feat: make LLM backoff configurable end-to-end

- extend LLMConfig with backoff delay/attempt/factor fields and thread them
  through LLMExtractionStrategy, LLMContentFilter, table extraction, and
  Docker API handlers
- expose the backoff parameter knobs on perform_completion_with_backoff/aperform_completion_with_backoff
  and document them in the md_v2 guides

+## Component Details
+
+### 1. Release Pipeline (release.yml)
+
+#### Purpose
+Fast publication of Python package and GitHub release.
+
+#### Input
+- **Trigger**: Git tag matching `v*` (excluding `test-v*`)
+- **Example**: `v1.2.3`
+
+#### Processing Stages
+
+##### Stage 1: Version Extraction
+```bash
+Input:  refs/tags/v1.2.3
+Output: VERSION=1.2.3
+```
+
+**Implementation**:
+```bash
+TAG_VERSION=${GITHUB_REF#refs/tags/v}  # Remove 'refs/tags/v' prefix
+echo "VERSION=$TAG_VERSION" >> $GITHUB_OUTPUT
+```
+
+##### Stage 2: Version Validation
+```bash
+Input:  TAG_VERSION=1.2.3
+Check:  crawl4ai/__version__.py contains __version__ = "1.2.3"
+Output: Pass/Fail
+```
+
+**Implementation**:
+```bash
+PACKAGE_VERSION=$(python -c "from crawl4ai.__version__ import __version__; print(__version__)")
+if [ "$TAG_VERSION" != "$PACKAGE_VERSION" ]; then
+  exit 1
+fi
+```
+
+##### Stage 3: Package Build
+```bash
+Input:  Source code + pyproject.toml
+Output: dist/crawl4ai-1.2.3.tar.gz
+        dist/crawl4ai-1.2.3-py3-none-any.whl
+```
+
+**Implementation**:
+```bash
+python -m build
+# Uses build backend defined in pyproject.toml
+```
+
+##### Stage 4: PyPI Upload
+```bash
+Input:  dist/*.{tar.gz,whl}
+Auth:   PYPI_TOKEN
+Output: Package published to PyPI
+```
+
+**Implementation**:
+```bash
+twine upload dist/*
+# Environment:
+#   TWINE_USERNAME: __token__
+#   TWINE_PASSWORD: ${{ secrets.PYPI_TOKEN }}
+```
+
+##### Stage 5: GitHub Release Creation
+```bash
+Input:  Tag: v1.2.3
+        Body: Markdown content
+Output: Published GitHub release
+```
+
+**Implementation**:
+```yaml
+uses: softprops/action-gh-release@v2
+with:
+  tag_name: v1.2.3
+  name: Release v1.2.3
+  body: |
+    Installation instructions and changelog
+  draft: false
+  prerelease: false
+```
+
+#### Output
+- **PyPI Package**: https://pypi.org/project/crawl4ai/1.2.3/
+- **GitHub Release**: Published release on repository
+- **Event**: `release.published` (triggers Docker workflow)
+
+#### Timeline
+```
+0:00 - Tag pushed
+0:01 - Checkout + Python setup
+0:02 - Version validation
+0:03 - Package build
+0:04 - PyPI upload starts
+0:06 - PyPI upload complete
+0:07 - GitHub release created
+0:08 - Workflow complete
+```
+
+---
+
+### 2. Docker Release Pipeline (docker-release.yml)
+
+#### Purpose
+Build and publish multi-architecture Docker images.
+
+#### Inputs
+
+##### Input 1: Release Event (Automatic)
+```yaml
+Event: release.published
+Data:  github.event.release.tag_name = "v1.2.3"
+```
+
+##### Input 2: Docker Rebuild Tag (Manual)
+```yaml
+Tag: docker-rebuild-v1.2.3
+```
+
+#### Processing Stages
+
+##### Stage 1: Version Detection
+```bash
+# From release event:
+VERSION = github.event.release.tag_name.strip("v")
+# Result: "1.2.3"
+
+# From rebuild tag:
+VERSION = GITHUB_REF.replace("refs/tags/docker-rebuild-v", "")
+# Result: "1.2.3"
+```
+
+##### Stage 2: Semantic Version Parsing
+```bash
+Input:  VERSION=1.2.3
+Output: MAJOR=1
+        MINOR=1.2
+        PATCH=3 (implicit)
+```
+
+**Implementation**:
+```bash
+MAJOR=$(echo $VERSION | cut -d. -f1)    # Extract first component
+MINOR=$(echo $VERSION | cut -d. -f1-2)  # Extract first two components
+```
+
+##### Stage 3: Multi-Architecture Setup
+```yaml
+Setup:
+  - Docker Buildx (multi-platform builder)
+  - QEMU (ARM emulation on x86)
+
+Platforms:
+  - linux/amd64 (x86_64)
+  - linux/arm64 (aarch64)
+```
+
+**Architecture**:
+```
+GitHub Runner (linux/amd64)
+  ├─ Buildx Builder
+  │   ├─ Native: Build linux/amd64 image
+  │   └─ QEMU: Emulate ARM to build linux/arm64 image
+  └─ Generate manifest list (points to both images)
+```
+
+##### Stage 4: Docker Hub Authentication
+```bash
+Input:  DOCKER_USERNAME
+        DOCKER_TOKEN
+Output: Authenticated Docker client
+```
+
+##### Stage 5: Build with Cache
+```yaml
+Cache Configuration:
+  cache-from: type=gha           # Read from GitHub Actions cache
+  cache-to: type=gha,mode=max    # Write all layers
+
+Cache Key Components:
+  - Workflow file path
+  - Branch name
+  - Architecture (amd64/arm64)
+```
+
+**Cache Hierarchy**:
+```
+Cache Entry: main/docker-release.yml/linux-amd64
+  ├─ Layer: sha256:abc123... (FROM python:3.12)
+  ├─ Layer: sha256:def456... (RUN apt-get update)
+  ├─ Layer: sha256:ghi789... (COPY requirements.txt)
+  ├─ Layer: sha256:jkl012... (RUN pip install)
+  └─ Layer: sha256:mno345... (COPY . /app)
+
+Cache Hit/Miss Logic:
+  - If layer input unchanged → cache hit → skip build
+  - If layer input changed → cache miss → rebuild + all subsequent layers
+```
+
+##### Stage 6: Tag Generation
+```bash
+Input:  VERSION=1.2.3, MAJOR=1, MINOR=1.2
+
+Output Tags:
+  - unclecode/crawl4ai:1.2.3    (exact version)
+  - unclecode/crawl4ai:1.2      (minor version)
+  - unclecode/crawl4ai:1        (major version)
+  - unclecode/crawl4ai:latest   (latest stable)
+```
+
+**Tag Strategy**:
+- All tags point to same image SHA
+- Users can pin to desired stability level
+- Pushing new version updates `1`, `1.2`, and `latest` automatically
+
+##### Stage 7: Push to Registry
+```bash
+For each tag:
+  For each platform (amd64, arm64):
+    Push image to Docker Hub
+
+Create manifest list:
+  Manifest: unclecode/crawl4ai:1.2.3
+    ├─ linux/amd64: sha256:abc...
+    └─ linux/arm64: sha256:def...
+
+Docker CLI automatically selects correct platform on pull
+```
+
+#### Output
+- **Docker Images**: 4 tags × 2 platforms = 8 image variants + 4 manifests
+- **Docker Hub**: https://hub.docker.com/r/unclecode/crawl4ai/tags
+
+#### Timeline
+
+**Cold Cache (First Build)**:
+```
+0:00 - Release event received
+0:01 - Checkout + Buildx setup
+0:02 - Docker Hub auth
+0:03 - Start build (amd64)
+0:08 - Complete amd64 build
+0:09 - Start build (arm64)
+0:14 - Complete arm64 build
+0:15 - Generate manifests
+0:16 - Push all tags
+0:17 - Workflow complete

+## Security Architecture
+
+### Threat Model
+
+#### Threats Mitigated
+
+1. **Secret Exposure**
+   - Mitigation: GitHub Actions secret masking
+   - Evidence: Secrets never appear in logs
+
+2. **Unauthorized Package Upload**
+   - Mitigation: Scoped PyPI tokens
+   - Evidence: Token limited to `crawl4ai` project
+
+3. **Man-in-the-Middle**
+   - Mitigation: HTTPS for all API calls
+   - Evidence: PyPI, Docker Hub, GitHub all use TLS
+
+4. **Supply Chain Tampering**
+   - Mitigation: Immutable artifacts, content checksums
+   - Evidence: PyPI stores SHA256, Docker uses content-addressable storage
+
+#### Trust Boundaries

+```
+Creation (Developer)

+  ├─► PyPI: Create API token (scoped to project)
+  ├─► Docker Hub: Create access token (read/write)
+  │
+  ▼
+Storage (GitHub)
+  │
+  ├─► Encrypted at rest (AES-256)
+  ├─► Access controlled (repo-scoped)
+  │
+  ▼
+Usage (Workflow)
+  │
+  ├─► Injected as env vars
+  ├─► Masked in logs (GitHub redacts on output)
+  ├─► Never persisted to disk (in-memory only)
+  │
+  ▼
+Transmission (API Call)
+  │
+  ├─► HTTPS only
+  ├─► TLS 1.2+ with strong ciphers
+  │
+  ▼
+Rotation (Manual)
+  │
+  └─► Regenerate on PyPI/Docker Hub
+      Update GitHub secret

+
+## Performance Characteristics
+
+### Release Pipeline Performance
+
+| Metric | Value | Notes |
+|--------|-------|-------|
+| Cold start | ~2-3 min | First run on new runner |
+| Warm start | ~2-3 min | Minimal caching benefit |
+| PyPI upload | ~30-60 sec | Network-bound |
+| Package build | ~30 sec | CPU-bound |
+| Parallelization | None | Sequential by design |
+
+### Docker Pipeline Performance
+
+| Metric | Cold Cache | Warm Cache (code) | Warm Cache (deps) |
+|--------|-----------|-------------------|-------------------|
+| Total time | 10-15 min | 1-2 min | 3-5 min |
+| amd64 build | 5-7 min | 30-60 sec | 1-2 min |
+| arm64 build | 5-7 min | 30-60 sec | 1-2 min |
+| Push time | 1-2 min | 30 sec | 30 sec |
+| Cache hit rate | 0% | 85% | 60% |
+
+### Cache Performance Model
+
+```python
+def estimate_build_time(changes):
+    base_time = 60  # seconds (setup + push)
+
+    if "Dockerfile" in changes:
+        return base_time + (10 * 60)  # Full rebuild: ~11 min
+    elif "requirements.txt" in changes:
+        return base_time + (3 * 60)   # Deps rebuild: ~4 min
+    elif any(f.endswith(".py") for f in changes):
+        return base_time + 60          # Code only: ~2 min
+    else:
+        return base_time               # No changes: ~1 min
+```
+
+---
+
+## Scalability Considerations
+
+### Current Limits
+
+| Resource | Limit | Impact |
+|----------|-------|--------|
+| Workflow concurrency | 20 (default) | Max 20 releases in parallel |
+| Artifact storage | 500 MB/artifact | PyPI packages small (<10 MB) |
+| Cache storage | 10 GB/repo | Docker layers fit comfortably |
+| Workflow run time | 6 hours | Plenty of headroom |
+
+### Scaling Strategies
+
+#### Horizontal Scaling (Multiple Repos)
+```
+crawl4ai (main)
+  ├─ release.yml
+  └─ docker-release.yml
+
+crawl4ai-plugins (separate)
+  ├─ release.yml
+  └─ docker-release.yml
+
+Each repo has independent:
+  - Secrets
+  - Cache (10 GB each)
+  - Concurrency limits (20 each)
+```
+
+#### Vertical Scaling (Larger Runners)
+```yaml
+jobs:
+  docker:
+    runs-on: ubuntu-latest-8-cores  # GitHub-hosted larger runner
+    # 4x faster builds for CPU-bound layers
+```
+
+---
+
+## Disaster Recovery
+
+### Failure Scenarios
+
+#### Scenario 1: Release Pipeline Fails
+
+**Failure Point**: PyPI upload fails (network error)
+
+**State**:
+- ✓ Version validated
+- ✓ Package built
+- ✗ PyPI upload
+- ✗ GitHub release
+
+**Recovery**:
+```bash
+# Manual upload
+twine upload dist/*
+
+# Retry workflow (re-run from GitHub Actions UI)
+```
+
+**Prevention**: Add retry logic to PyPI upload
+
+#### Scenario 2: Docker Pipeline Fails
+
+**Failure Point**: ARM build fails (dependency issue)
+
+**State**:
+- ✓ PyPI published
+- ✓ GitHub release created
+- ✓ amd64 image built
+- ✗ arm64 image build
+
+**Recovery**:
+```bash
+# Fix Dockerfile
+git commit -am "fix: ARM build dependency"
+
+# Trigger rebuild
+git tag docker-rebuild-v1.2.3
+git push origin docker-rebuild-v1.2.3
+```
+
+**Impact**: PyPI package available, only Docker ARM users affected
+
+#### Scenario 3: Partial Release
+
+**Failure Point**: GitHub release creation fails
+
+**State**:
+- ✓ PyPI published
+- ✗ GitHub release
+- ✗ Docker images
+
+**Recovery**:
+```bash
+# Create release manually
+gh release create v1.2.3 \
+  --title "Release v1.2.3" \
+  --notes "..."
+
+# This triggers docker-release.yml automatically
+```
+
+---
+
+## Monitoring and Observability
+
+### Metrics to Track
+
+#### Release Pipeline
+- Success rate (target: >99%)
+- Duration (target: <3 min)
+- PyPI upload time (target: <60 sec)
+
+#### Docker Pipeline
+- Success rate (target: >95%)
+- Duration (target: <15 min cold, <2 min warm)
+- Cache hit rate (target: >80% for code changes)
+
+### Alerting
+
+**Critical Alerts**:
+- Release pipeline failure (blocks release)
+- PyPI authentication failure (expired token)
+
+**Warning Alerts**:
+- Docker build >15 min (performance degradation)
+- Cache hit rate <50% (cache issue)
+
+### Logging
+
+**GitHub Actions Logs**:
+- Retention: 90 days
+- Downloadable: Yes
+- Searchable: Limited
+
+**Recommended External Logging**:
+```yaml
+- name: Send logs to external service
+  if: failure()
+  run: |
+    curl -X POST https://logs.example.com/api/v1/logs \
+      -H "Content-Type: application/json" \
+      -d "{\"workflow\": \"${{ github.workflow }}\", \"status\": \"failed\"}"
+```
+
+---
+
+## Future Enhancements
+
+### Planned Improvements
+
+1. **Automated Changelog Generation**
+   - Use conventional commits
+   - Generate CHANGELOG.md automatically
+
+2. **Pre-release Testing**
+   - Test builds on `test-v*` tags
+   - Upload to TestPyPI
+
+3. **Notification System**
+   - Slack/Discord notifications on release
+   - Email on failure
+
+4. **Performance Optimization**
+   - Parallel Docker builds (amd64 + arm64 simultaneously)
+   - Persistent runners for better caching
+
+5. **Enhanced Validation**
+   - Smoke tests after PyPI upload
+   - Container security scanning

+### Asynchronous Jobs with Webhooks
+
+For long-running crawls or when you want to avoid keeping connections open, use the job queue endpoints. Instead of polling for results, configure a webhook to receive notifications when jobs complete.
+
+#### Why Use Jobs & Webhooks?
+
+- **No Polling Required** - Get notified when crawls complete instead of constantly checking status
+- **Better Resource Usage** - Free up client connections while jobs run in the background
+- **Scalable Architecture** - Ideal for high-volume crawling with TypeScript/Node.js clients or microservices
+- **Reliable Delivery** - Automatic retry with exponential backoff (5 attempts: 1s → 2s → 4s → 8s → 16s)
+
+#### How It Works
+
+1. **Submit Job** → POST to `/crawl/job` with optional `webhook_config`
+2. **Get Task ID** → Receive a `task_id` immediately
+3. **Job Runs** → Crawl executes in the background
+4. **Webhook Fired** → Server POSTs completion notification to your webhook URL
+5. **Fetch Results** → If data wasn't included in webhook, GET `/crawl/job/{task_id}`
+
+#### Quick Example
+
+```bash
+# Submit a crawl job with webhook notification
+curl -X POST http://localhost:11235/crawl/job \
+  -H "Content-Type: application/json" \
+  -d '{
+    "urls": ["https://example.com"],
+    "webhook_config": {
+      "webhook_url": "https://myapp.com/webhooks/crawl-complete",
+      "webhook_data_in_payload": false
+    }
+  }'
+
+# Response: {"task_id": "crawl_a1b2c3d4"}
+```
+
+**Your webhook receives:**
+```json
+{
+  "task_id": "crawl_a1b2c3d4",
+  "task_type": "crawl",
+  "status": "completed",
+  "timestamp": "2025-10-21T10:30:00.000000+00:00",
+  "urls": ["https://example.com"]
+}
+```
+
+Then fetch the results:
+```bash
+curl http://localhost:11235/crawl/job/crawl_a1b2c3d4
+```
+
+#### Include Data in Webhook
+
+Set `webhook_data_in_payload: true` to receive the full crawl results directly in the webhook:
+
+```bash
+curl -X POST http://localhost:11235/crawl/job \
+  -H "Content-Type: application/json" \
+  -d '{
+    "urls": ["https://example.com"],
+    "webhook_config": {
+      "webhook_url": "https://myapp.com/webhooks/crawl-complete",
+      "webhook_data_in_payload": true
+    }
+  }'
+```
+
+**Your webhook receives the complete data:**
+```json
+{
+  "task_id": "crawl_a1b2c3d4",
+  "task_type": "crawl",
+  "status": "completed",
+  "timestamp": "2025-10-21T10:30:00.000000+00:00",
+  "urls": ["https://example.com"],
+  "data": {
+    "markdown": "...",
+    "html": "...",
+    "links": {...},
+    "metadata": {...}
+  }
+}
+```
+
+#### Webhook Authentication
+
+Add custom headers for authentication:
+
+```json
+{
+  "urls": ["https://example.com"],
+  "webhook_config": {
+    "webhook_url": "https://myapp.com/webhooks/crawl",
+    "webhook_data_in_payload": false,
+    "webhook_headers": {
+      "X-Webhook-Secret": "your-secret-token",
+      "X-Service-ID": "crawl4ai-prod"
+    }
+  }
+}
+```
+
+#### Global Default Webhook
+
+Configure a default webhook URL in `config.yml` for all jobs:
+
+```yaml
+webhooks:
+  enabled: true
+  default_url: "https://myapp.com/webhooks/default"
+  data_in_payload: false
+  retry:
+    max_attempts: 5
+    initial_delay_ms: 1000
+    max_delay_ms: 32000
+    timeout_ms: 30000
+```
+
+Now jobs without `webhook_config` automatically use the default webhook.
+
+#### Job Status Polling (Without Webhooks)
+
+If you prefer polling instead of webhooks, just omit `webhook_config`:
+
+```bash
+# Submit job
+curl -X POST http://localhost:11235/crawl/job \
+  -H "Content-Type: application/json" \
+  -d '{"urls": ["https://example.com"]}'
+# Response: {"task_id": "crawl_xyz"}
+
+# Poll for status
+curl http://localhost:11235/crawl/job/crawl_xyz
+```
+
+The response includes `status` field: `"processing"`, `"completed"`, or `"failed"`.
+
+#### LLM Extraction Jobs with Webhooks
+
+The same webhook system works for LLM extraction jobs via `/llm/job`:
+
+```bash
+# Submit LLM extraction job with webhook
+curl -X POST http://localhost:11235/llm/job \
+  -H "Content-Type: application/json" \
+  -d '{
+    "url": "https://example.com/article",
+    "q": "Extract the article title, author, and main points",
+    "provider": "openai/gpt-4o-mini",
+    "webhook_config": {
+      "webhook_url": "https://myapp.com/webhooks/llm-complete",
+      "webhook_data_in_payload": true,
+      "webhook_headers": {
+        "X-Webhook-Secret": "your-secret-token"
+      }
+    }
+  }'
+
+# Response: {"task_id": "llm_1234567890"}
+```
+
+**Your webhook receives:**
+```json
+{
+  "task_id": "llm_1234567890",
+  "task_type": "llm_extraction",
+  "status": "completed",
+  "timestamp": "2025-10-22T12:30:00.000000+00:00",
+  "urls": ["https://example.com/article"],
+  "data": {
+    "extracted_content": {
+      "title": "Understanding Web Scraping",
+      "author": "John Doe",
+      "main_points": ["Point 1", "Point 2", "Point 3"]
+    }
+  }
+}
+```
+
+**Key Differences for LLM Jobs:**
+- Task type is `"llm_extraction"` instead of `"crawl"`
+- Extracted data is in `data.extracted_content`
+- Single URL only (not an array)
+- Supports schema-based extraction with `schema` parameter
+
+> 💡 **Pro tip**: See [WEBHOOK_EXAMPLES.md](./WEBHOOK_EXAMPLES.md) for detailed examples including TypeScript client code, Flask webhook handlers, and failure handling.

+# Crawl4AI Docker Memory & Pool Optimization - Implementation Log
+
+## Critical Issues Identified
+
+### Memory Management
+- **Host vs Container**: `psutil.virtual_memory()` reported host memory, not container limits
+- **Browser Pooling**: No pool reuse - every endpoint created new browsers
+- **Warmup Waste**: Permanent browser sat idle with mismatched config signature
+- **Idle Cleanup**: 30min TTL too long, janitor ran every 60s
+- **Endpoint Inconsistency**: 75% of endpoints bypassed pool (`/md`, `/html`, `/screenshot`, `/pdf`, `/execute_js`, `/llm`)
+
+### Pool Design Flaws
+- **Config Mismatch**: Permanent browser used `config.yml` args, endpoints used empty `BrowserConfig()`
+- **Logging Level**: Pool hit markers at DEBUG, invisible with INFO logging
+
+## Implementation Changes
+
+### 1. Container-Aware Memory Detection (`utils.py`)
+```python
+def get_container_memory_percent() -> float:
+    # Try cgroup v2 → v1 → fallback to psutil
+    # Reads /sys/fs/cgroup/memory.{current,max} OR memory/memory.{usage,limit}_in_bytes
+```
+
+### 2. Smart Browser Pool (`crawler_pool.py`)
+**3-Tier System:**
+- **PERMANENT**: Always-ready default browser (never cleaned)
+- **HOT_POOL**: Configs used 3+ times (longer TTL)
+- **COLD_POOL**: New/rare configs (short TTL)
+
+**Key Functions:**
+- `get_crawler(cfg)`: Check permanent → hot → cold → create new
+- `init_permanent(cfg)`: Initialize permanent at startup
+- `janitor()`: Adaptive cleanup (10s/30s/60s intervals based on memory)
+- `_sig(cfg)`: SHA1 hash of config dict for pool keys
+
+**Logging Fix**: Changed `logger.debug()` → `logger.info()` for pool hits
+
+### 3. Endpoint Unification
+**Helper Function** (`server.py`):
+```python
+def get_default_browser_config() -> BrowserConfig:
+    return BrowserConfig(
+        extra_args=config["crawler"]["browser"].get("extra_args", []),
+        **config["crawler"]["browser"].get("kwargs", {}),
+    )
+```
+
+**Migrated Endpoints:**
+- `/html`, `/screenshot`, `/pdf`, `/execute_js` → use `get_default_browser_config()`
+- `handle_llm_qa()`, `handle_markdown_request()` → same
+
+**Result**: All endpoints now hit permanent browser pool
+
+### 4. Config Updates (`config.yml`)
+- `idle_ttl_sec: 1800` → `300` (30min → 5min base TTL)
+- `port: 11234` → `11235` (fixed mismatch with Gunicorn)
+
+### 5. Lifespan Fix (`server.py`)
+```python
+await init_permanent(BrowserConfig(
+    extra_args=config["crawler"]["browser"].get("extra_args", []),
+    **config["crawler"]["browser"].get("kwargs", {}),
+))
+```
+Permanent browser now matches endpoint config signatures
+
+## Test Results
+
+### Test 1: Basic Health
+- 10 requests to `/health`
+- **Result**: 100% success, avg 3ms latency
+- **Baseline**: Container starts in ~5s, 270 MB idle
+
+### Test 2: Memory Monitoring
+- 20 requests with Docker stats tracking
+- **Result**: 100% success, no memory leak (-0.2 MB delta)
+- **Baseline**: 269.7 MB container overhead
+
+### Test 3: Pool Validation
+- 30 requests to `/html` endpoint
+- **Result**: **100% permanent browser hits**, 0 new browsers created
+- **Memory**: 287 MB baseline → 396 MB active (+109 MB)
+- **Latency**: Avg 4s (includes network to httpbin.org)
+
+### Test 4: Concurrent Load
+- Light (10) → Medium (50) → Heavy (100) concurrent
+- **Total**: 320 requests
+- **Result**: 100% success, **320/320 permanent hits**, 0 new browsers
+- **Memory**: 269 MB → peak 1533 MB → final 993 MB
+- **Latency**: P99 at 100 concurrent = 34s (expected with single browser)
+
+### Test 5: Pool Stress (Mixed Configs)
+- 20 requests with 4 different viewport configs
+- **Result**: 4 new browsers, 4 cold hits, **4 promotions to hot**, 8 hot hits
+- **Reuse Rate**: 60% (12 pool hits / 20 requests)
+- **Memory**: 270 MB → 928 MB peak (+658 MB = ~165 MB per browser)
+- **Proves**: Cold → hot promotion at 3 uses working perfectly
+
+### Test 6: Multi-Endpoint
+- 10 requests each: `/html`, `/screenshot`, `/pdf`, `/crawl`
+- **Result**: 100% success across all 4 endpoints
+- **Latency**: 5-8s avg (PDF slowest at 7.2s)
+
+### Test 7: Cleanup Verification
+- 20 requests (load spike) → 90s idle
+- **Memory**: 269 MB → peak 1107 MB → final 780 MB
+- **Recovery**: 327 MB (39%) - partial cleanup
+- **Note**: Hot pool browsers persist (by design), janitor working correctly
+
+## Performance Metrics
+
+| Metric | Before | After | Improvement |
+|--------|--------|-------|-------------|
+| Pool Reuse | 0% | 100% (default config) | ∞ |
+| Memory Leak | Unknown | 0 MB/cycle | Stable |
+| Browser Reuse | No | Yes | ~3-5s saved per request |
+| Idle Memory | 500-700 MB × N | 270-400 MB | 10x reduction |
+| Concurrent Capacity | ~20 | 100+ | 5x |
+
+## Key Learnings
+
+1. **Config Signature Matching**: Permanent browser MUST match endpoint default config exactly (SHA1 hash)
+2. **Logging Levels**: Pool diagnostics need INFO level, not DEBUG
+3. **Memory in Docker**: Must read cgroup files, not host metrics
+4. **Janitor Timing**: 60s interval adequate, but TTLs should be short (5min) for cold pool
+5. **Hot Promotion**: 3-use threshold works well for production patterns
+6. **Memory Per Browser**: ~150-200 MB per Chromium instance with headless + text_mode
+
+## Test Infrastructure
+
+**Location**: `deploy/docker/tests/`
+**Dependencies**: `httpx`, `docker` (Python SDK)
+**Pattern**: Sequential build - each test adds one capability
+
+**Files**:
+- `test_1_basic.py`: Health check + container lifecycle
+- `test_2_memory.py`: + Docker stats monitoring
+- `test_3_pool.py`: + Log analysis for pool markers
+- `test_4_concurrent.py`: + asyncio.Semaphore for concurrency control
+- `test_5_pool_stress.py`: + Config variants (viewports)
+- `test_6_multi_endpoint.py`: + Multiple endpoint testing
+- `test_7_cleanup.py`: + Time-series memory tracking for janitor
+
+**Run Pattern**:
+```bash
+cd deploy/docker/tests
+pip install -r requirements.txt
+# Rebuild after code changes:
+cd /path/to/repo && docker buildx build -t crawl4ai-local:latest --load .
+# Run test:
+python test_N_name.py
+```
+
+## Architecture Decisions
+
+**Why Permanent Browser?**
+- 90% of requests use default config → single browser serves most traffic
+- Eliminates 3-5s startup overhead per request
+
+**Why 3-Tier Pool?**
+- Permanent: Zero cost for common case
+- Hot: Amortized cost for frequent variants
+- Cold: Lazy allocation for rare configs
+
+**Why Adaptive Janitor?**
+- Memory pressure triggers aggressive cleanup
+- Low memory allows longer TTLs for better reuse
+
+**Why Not Close After Each Request?**
+- Browser startup: 3-5s overhead
+- Pool reuse: <100ms overhead
+- Net: 30-50x faster
+
+## Future Optimizations
+
+1. **Request Queuing**: When at capacity, queue instead of reject
+2. **Pre-warming**: Predict common configs, pre-create browsers
+3. **Metrics Export**: Prometheus metrics for pool efficiency
+4. **Config Normalization**: Group similar viewports (e.g., 1920±50 → 1920)
+
+## Critical Code Paths
+
+**Browser Acquisition** (`crawler_pool.py:34-78`):
+```
+get_crawler(cfg) →
+  _sig(cfg) →
+  if sig == DEFAULT_CONFIG_SIG → PERMANENT
+  elif sig in HOT_POOL → HOT_POOL[sig]
+  elif sig in COLD_POOL → promote if count >= 3
+  else → create new in COLD_POOL
+```
+
+**Janitor Loop** (`crawler_pool.py:107-146`):
+```
+while True:
+  mem% = get_container_memory_percent()
+  if mem% > 80: interval=10s, cold_ttl=30s
+  elif mem% > 60: interval=30s, cold_ttl=60s
+  else: interval=60s, cold_ttl=300s
+  sleep(interval)
+  close idle browsers (COLD then HOT)
+```
+
+**Endpoint Pattern** (`server.py` example):
+```python
+@app.post("/html")
+async def generate_html(...):
+    from crawler_pool import get_crawler
+    crawler = await get_crawler(get_default_browser_config())
+    results = await crawler.arun(url=body.url, config=cfg)
+    # No crawler.close() - returned to pool
+```
+
+## Debugging Tips
+
+**Check Pool Activity**:
+```bash
+docker logs crawl4ai-test | grep -E "(🔥|♨️|❄️|🆕|⬆️)"
+```
+
+**Verify Config Signature**:
+```python
+from crawl4ai import BrowserConfig
+import json, hashlib
+cfg = BrowserConfig(...)
+sig = hashlib.sha1(json.dumps(cfg.to_dict(), sort_keys=True).encode()).hexdigest()
+print(sig[:8])  # Compare with logs
+```
+
+**Monitor Memory**:
+```bash
+docker stats crawl4ai-test
+```
+
+## Known Limitations
+
+- **Mac Docker Stats**: CPU metrics unreliable, memory works
+- **PDF Generation**: Slowest endpoint (~7s), no optimization yet
+- **Hot Pool Persistence**: May hold memory longer than needed (trade-off for performance)
+- **Janitor Lag**: Up to 60s before cleanup triggers in low-memory scenarios

+# Webhook Feature Examples
+
+This document provides examples of how to use the webhook feature for crawl jobs in Crawl4AI.
+
+## Overview
+
+The webhook feature allows you to receive notifications when crawl jobs complete, eliminating the need for polling. Webhooks are sent with exponential backoff retry logic to ensure reliable delivery.
+
+## Configuration
+
+### Global Configuration (config.yml)
+
+You can configure default webhook settings in `config.yml`:
+
+```yaml
+webhooks:
+  enabled: true
+  default_url: null  # Optional: default webhook URL for all jobs
+  data_in_payload: false  # Optional: default behavior for including data
+  retry:
+    max_attempts: 5
+    initial_delay_ms: 1000  # 1s, 2s, 4s, 8s, 16s exponential backoff
+    max_delay_ms: 32000
+    timeout_ms: 30000  # 30s timeout per webhook call
+  headers:  # Optional: default headers to include
+    User-Agent: "Crawl4AI-Webhook/1.0"
+```
+
+## API Usage Examples
+
+### Example 1: Basic Webhook (Notification Only)
+
+Send a webhook notification without including the crawl data in the payload.
+
+**Request:**
+```bash
+curl -X POST http://localhost:11235/crawl/job \
+  -H "Content-Type: application/json" \
+  -d '{
+    "urls": ["https://example.com"],
+    "webhook_config": {
+      "webhook_url": "https://myapp.com/webhooks/crawl-complete",
+      "webhook_data_in_payload": false
+    }
+  }'
+```
+
+**Response:**
+```json
+{
+  "task_id": "crawl_a1b2c3d4"
+}
+```
+
+**Webhook Payload Received:**
+```json
+{
+  "task_id": "crawl_a1b2c3d4",
+  "task_type": "crawl",
+  "status": "completed",
+  "timestamp": "2025-10-21T10:30:00.000000+00:00",
+  "urls": ["https://example.com"]
+}
+```
+
+Your webhook handler should then fetch the results:
+```bash
+curl http://localhost:11235/crawl/job/crawl_a1b2c3d4
+```
+
+### Example 2: Webhook with Data Included
+
+Include the full crawl results in the webhook payload.
+
+**Request:**
+```bash
+curl -X POST http://localhost:11235/crawl/job \
+  -H "Content-Type: application/json" \
+  -d '{
+    "urls": ["https://example.com"],
+    "webhook_config": {
+      "webhook_url": "https://myapp.com/webhooks/crawl-complete",
+      "webhook_data_in_payload": true
+    }
+  }'
+```
+
+**Webhook Payload Received:**
+```json
+{
+  "task_id": "crawl_a1b2c3d4",
+  "task_type": "crawl",
+  "status": "completed",
+  "timestamp": "2025-10-21T10:30:00.000000+00:00",
+  "urls": ["https://example.com"],
+  "data": {
+    "markdown": "...",
+    "html": "...",
+    "links": {...},
+    "metadata": {...}
+  }
+}
+```
+
+### Example 3: Webhook with Custom Headers
+
+Include custom headers for authentication or identification.
+
+**Request:**
+```bash
+curl -X POST http://localhost:11235/crawl/job \
+  -H "Content-Type: application/json" \
+  -d '{
+    "urls": ["https://example.com"],
+    "webhook_config": {
+      "webhook_url": "https://myapp.com/webhooks/crawl-complete",
+      "webhook_data_in_payload": false,
+      "webhook_headers": {
+        "X-Webhook-Secret": "my-secret-token",
+        "X-Service-ID": "crawl4ai-production"
+      }
+    }
+  }'
+```
+
+The webhook will be sent with these additional headers plus the default headers from config.
+
+### Example 4: Failure Notification
+
+When a crawl job fails, a webhook is sent with error details.
+
+**Webhook Payload on Failure:**
+```json
+{
+  "task_id": "crawl_a1b2c3d4",
+  "task_type": "crawl",
+  "status": "failed",
+  "timestamp": "2025-10-21T10:30:00.000000+00:00",
+  "urls": ["https://example.com"],
+  "error": "Connection timeout after 30s"
+}
+```
+
+### Example 5: Using Global Default Webhook
+
+If you set a `default_url` in config.yml, jobs without webhook_config will use it:
+
+**config.yml:**
+```yaml
+webhooks:
+  enabled: true
+  default_url: "https://myapp.com/webhooks/default"
+  data_in_payload: false
+```
+
+**Request (no webhook_config needed):**
+```bash
+curl -X POST http://localhost:11235/crawl/job \
+  -H "Content-Type: application/json" \
+  -d '{
+    "urls": ["https://example.com"]
+  }'
+```
+
+The webhook will be sent to the default URL configured in config.yml.
+
+### Example 6: LLM Extraction Job with Webhook
+
+Use webhooks with the LLM extraction endpoint for asynchronous processing.
+
+**Request:**
+```bash
+curl -X POST http://localhost:11235/llm/job \
+  -H "Content-Type: application/json" \
+  -d '{
+    "url": "https://example.com/article",
+    "q": "Extract the article title, author, and publication date",
+    "schema": "{\"type\": \"object\", \"properties\": {\"title\": {\"type\": \"string\"}, \"author\": {\"type\": \"string\"}, \"date\": {\"type\": \"string\"}}}",
+    "cache": false,
+    "provider": "openai/gpt-4o-mini",
+    "webhook_config": {
+      "webhook_url": "https://myapp.com/webhooks/llm-complete",
+      "webhook_data_in_payload": true
+    }
+  }'
+```
+
+**Response:**
+```json
+{
+  "task_id": "llm_1698765432_12345"
+}
+```
+
+**Webhook Payload Received:**
+```json
+{
+  "task_id": "llm_1698765432_12345",
+  "task_type": "llm_extraction",
+  "status": "completed",
+  "timestamp": "2025-10-21T10:30:00.000000+00:00",
+  "urls": ["https://example.com/article"],
+  "data": {
+    "extracted_content": {
+      "title": "Understanding Web Scraping",
+      "author": "John Doe",
+      "date": "2025-10-21"
+    }
+  }
+}
+```
+
+## Webhook Handler Example
+
+Here's a simple Python Flask webhook handler that supports both crawl and LLM extraction jobs:
+
+```python
+from flask import Flask, request, jsonify
+import requests
+
+app = Flask(__name__)
+
+@app.route('/webhooks/crawl-complete', methods=['POST'])
+def handle_crawl_webhook():
+    payload = request.json
+
+    task_id = payload['task_id']
+    task_type = payload['task_type']
+    status = payload['status']
+
+    if status == 'completed':
+        # If data not in payload, fetch it
+        if 'data' not in payload:
+            # Determine endpoint based on task type
+            endpoint = 'crawl' if task_type == 'crawl' else 'llm'
+            response = requests.get(f'http://localhost:11235/{endpoint}/job/{task_id}')
+            data = response.json()
+        else:
+            data = payload['data']
+
+        # Process based on task type
+        if task_type == 'crawl':
+            print(f"Processing crawl results for {task_id}")
+            # Handle crawl results
+            results = data.get('results', [])
+            for result in results:
+                print(f"  - {result.get('url')}: {len(result.get('markdown', ''))} chars")
+
+        elif task_type == 'llm_extraction':
+            print(f"Processing LLM extraction for {task_id}")
+            # Handle LLM extraction
+            # Note: Webhook sends 'extracted_content', API returns 'result'
+            extracted = data.get('extracted_content', data.get('result', {}))
+            print(f"  - Extracted: {extracted}")
+
+        # Your business logic here...
+
+    elif status == 'failed':
+        error = payload.get('error', 'Unknown error')
+        print(f"{task_type} job {task_id} failed: {error}")
+        # Handle failure...
+
+    return jsonify({"status": "received"}), 200
+
+if __name__ == '__main__':
+    app.run(port=8080)
+```
+
+## Retry Logic
+
+The webhook delivery service uses exponential backoff retry logic:
+
+- **Attempts:** Up to 5 attempts by default
+- **Delays:** 1s → 2s → 4s → 8s → 16s
+- **Timeout:** 30 seconds per attempt
+- **Retry Conditions:**
+  - Server errors (5xx status codes)
+  - Network errors
+  - Timeouts
+- **No Retry:**
+  - Client errors (4xx status codes)
+  - Successful delivery (2xx status codes)
+
+## Benefits
+
+1. **No Polling Required** - Eliminates constant API calls to check job status
+2. **Real-time Notifications** - Immediate notification when jobs complete
+3. **Reliable Delivery** - Exponential backoff ensures webhooks are delivered
+4. **Flexible** - Choose between notification-only or full data delivery
+5. **Secure** - Support for custom headers for authentication
+6. **Configurable** - Global defaults or per-job configuration
+7. **Universal Support** - Works with both `/crawl/job` and `/llm/job` endpoints
+

+    webhook_headers: {
+      'X-Webhook-Secret': 'my-secret'
+    }
+  }
+});
+```
+
+## Monitoring and Debugging
+
+Webhook delivery attempts are logged at INFO level:

 - **Monitoring Systems**: Faster health checks and status page monitoring
 - **Data Aggregation**: Improved performance for real-time data collection
 
-## 🧹 Memory Management Refactor: Cleaner Architecture
-
-**The Problem:** Memory utilities were scattered and difficult to maintain, with potential import conflicts and unclear organization.
-
-**My Solution:** I consolidated all memory-related utilities into the main `utils.py` module, creating a cleaner, more maintainable architecture.
-
-### Improved Memory Handling
-
-```python
-# All memory utilities now consolidated
-from crawl4ai.utils import get_true_memory_usage_percent, MemoryMonitor
-
-# Enhanced memory monitoring
-monitor = MemoryMonitor()
-monitor.start_monitoring()
-
-async with AsyncWebCrawler() as crawler:
-    # Memory-efficient batch processing
-    results = await crawler.arun_many(large_url_list)
-    
-    # Get accurate memory metrics
-    memory_usage = get_true_memory_usage_percent()
-    memory_report = monitor.get_report()
-    
-    print(f"Memory efficiency: {memory_report['efficiency']:.1f}%")
-    print(f"Peak usage: {memory_report['peak_mb']:.1f} MB")
-```
-
-**Expected Real-World Impact:**
-- **Production Stability**: More reliable memory tracking and management
-- **Code Maintainability**: Cleaner architecture for easier debugging
-- **Import Clarity**: Resolved potential conflicts and import issues
-- **Developer Experience**: Simpler API for memory monitoring

+
+Today I'm releasing Crawl4AI v0.7.5—focused on extensibility and security. This update introduces the Docker Hooks System for pipeline customization, enhanced LLM integration, and important security improvements.
+
+## 🎯 What's New at a Glance
+
+- **Docker Hooks System**: Custom Python functions at key pipeline points with function-based API
+- **Function-Based Hooks**: New `hooks_to_string()` utility with Docker client auto-conversion
+- **Enhanced LLM Integration**: Custom providers with temperature control
+- **HTTPS Preservation**: Secure internal link handling
+- **Bug Fixes**: Resolved multiple community-reported issues
+- **Improved Docker Error Handling**: Better debugging and reliability
+
+## 🔧 Docker Hooks System: Pipeline Customization
+
+Every scraping project needs custom logic—authentication, performance optimization, content processing. Traditional solutions require forking or complex workarounds. Docker Hooks let you inject custom Python functions at 8 key points in the crawling pipeline.
+
+### Real Example: Authentication & Performance
+
+```python
+import requests
+
+# Real working hooks for httpbin.org
+hooks_config = {
+    "on_page_context_created": """
+async def hook(page, context, **kwargs):
+    print("Hook: Setting up page context")
+    # Block images to speed up crawling
+    await context.route("**/*.{png,jpg,jpeg,gif,webp}", lambda route: route.abort())
+    print("Hook: Images blocked")
+    return page
+""",
+
+    "before_retrieve_html": """
+async def hook(page, context, **kwargs):
+    print("Hook: Before retrieving HTML")
+    # Scroll to bottom to load lazy content
+    await page.evaluate("window.scrollTo(0, document.body.scrollHeight)")
+    await page.wait_for_timeout(1000)
+    print("Hook: Scrolled to bottom")
+    return page
+""",
+
+    "before_goto": """
+async def hook(page, context, url, **kwargs):
+    print(f"Hook: About to navigate to {url}")
+    # Add custom headers
+    await page.set_extra_http_headers({
+        'X-Test-Header': 'crawl4ai-hooks-test'
+    })
+    return page
+"""
+}
+
+# Test with Docker API
+payload = {
+    "urls": ["https://httpbin.org/html"],
+    "hooks": {
+        "code": hooks_config,
+        "timeout": 30
+    }
+}
+
+response = requests.post("http://localhost:11235/crawl", json=payload)
+result = response.json()
+
+if result.get('success'):
+    print("✅ Hooks executed successfully!")
+    print(f"Content length: {len(result.get('markdown', ''))} characters")
+```
+
+**Available Hook Points:**
+- `on_browser_created`: Browser setup
+- `on_page_context_created`: Page context configuration
+- `before_goto`: Pre-navigation setup
+- `after_goto`: Post-navigation processing
+- `on_user_agent_updated`: User agent changes
+- `on_execution_started`: Crawl initialization
+- `before_retrieve_html`: Pre-extraction processing
+- `before_return_html`: Final HTML processing
+
+### Function-Based Hooks API
+
+Writing hooks as strings works, but lacks IDE support and type checking. v0.7.5 introduces a function-based approach with automatic conversion!
+
+**Option 1: Using the `hooks_to_string()` Utility**
+
+```python
+from crawl4ai import hooks_to_string
+import requests
+
+# Define hooks as regular Python functions (with full IDE support!)
+async def on_page_context_created(page, context, **kwargs):
+    """Block images to speed up crawling"""
+    await context.route("**/*.{png,jpg,jpeg,gif,webp}", lambda route: route.abort())
+    await page.set_viewport_size({"width": 1920, "height": 1080})
+    return page
+
+async def before_goto(page, context, url, **kwargs):
+    """Add custom headers"""
+    await page.set_extra_http_headers({
+        'X-Crawl4AI': 'v0.7.5',
+        'X-Custom-Header': 'my-value'
+    })
+    return page
+
+# Convert functions to strings
+hooks_code = hooks_to_string({
+    "on_page_context_created": on_page_context_created,
+    "before_goto": before_goto
+})
+
+# Use with REST API
+payload = {
+    "urls": ["https://httpbin.org/html"],
+    "hooks": {"code": hooks_code, "timeout": 30}
+}
+response = requests.post("http://localhost:11235/crawl", json=payload)
+```
+
+**Option 2: Docker Client with Automatic Conversion (Recommended!)**
+
+```python
+from crawl4ai.docker_client import Crawl4aiDockerClient
+
+# Define hooks as functions (same as above)
+async def on_page_context_created(page, context, **kwargs):
+    await context.route("**/*.{png,jpg,jpeg,gif,webp}", lambda route: route.abort())
+    return page
+
+async def before_retrieve_html(page, context, **kwargs):
+    # Scroll to load lazy content
+    await page.evaluate("window.scrollTo(0, document.body.scrollHeight)")
+    await page.wait_for_timeout(1000)
+    return page
+
+# Use Docker client - conversion happens automatically!
+client = Crawl4aiDockerClient(base_url="http://localhost:11235")
+
+results = await client.crawl(
+    urls=["https://httpbin.org/html"],
+    hooks={
+        "on_page_context_created": on_page_context_created,
+        "before_retrieve_html": before_retrieve_html
+    },
+    hooks_timeout=30
+)
+
+if results and results.success:
+    print(f"✅ Hooks executed! HTML length: {len(results.html)}")
+```
+
+**Benefits of Function-Based Hooks:**
+- ✅ Full IDE support (autocomplete, syntax highlighting)
+- ✅ Type checking and linting
+- ✅ Easier to test and debug
+- ✅ Reusable across projects
+- ✅ Automatic conversion in Docker client
+- ✅ No breaking changes - string hooks still work!
+
+## 🤖 Enhanced LLM Integration
+
+Enhanced LLM integration with custom providers, temperature control, and base URL configuration.
+
+### Multi-Provider Support
+
+```python
+from crawl4ai import AsyncWebCrawler, CrawlerRunConfig
+from crawl4ai.extraction_strategy import LLMExtractionStrategy
+
+# Test with different providers
+async def test_llm_providers():
+    # OpenAI with custom temperature
+    openai_strategy = LLMExtractionStrategy(
+        provider="gemini/gemini-2.5-flash-lite",
+        api_token="your-api-token",
+        temperature=0.7,  # New in v0.7.5
+        instruction="Summarize this page in one sentence"
+    )
+
+    async with AsyncWebCrawler() as crawler:
+        result = await crawler.arun(
+            "https://example.com",
+            config=CrawlerRunConfig(extraction_strategy=openai_strategy)
+        )
+
+        if result.success:
+            print("✅ LLM extraction completed")
+            print(result.extracted_content)
+
+# Docker API with enhanced LLM config
+llm_payload = {
+    "url": "https://example.com",
+    "f": "llm",
+    "q": "Summarize this page in one sentence.",
+    "provider": "gemini/gemini-2.5-flash-lite",
+    "temperature": 0.7
+}
+
+response = requests.post("http://localhost:11235/md", json=llm_payload)
+```
+
+**New Features:**
+- Custom `temperature` parameter for creativity control
+- `base_url` for custom API endpoints
+- Multi-provider environment variable support
+- Docker API integration
+
+## 🔒 HTTPS Preservation
+
+**The Problem:** Modern web apps require HTTPS everywhere. When crawlers downgrade internal links from HTTPS to HTTP, authentication breaks and security warnings appear.
+
+**Solution:** HTTPS preservation maintains secure protocols throughout crawling.
+
+```python
+from crawl4ai import AsyncWebCrawler, CrawlerRunConfig, FilterChain, URLPatternFilter, BFSDeepCrawlStrategy
+
+async def test_https_preservation():
+    # Enable HTTPS preservation
+    url_filter = URLPatternFilter(
+        patterns=["^(https:\/\/)?quotes\.toscrape\.com(\/.*)?$"]
+    )
+
+    config = CrawlerRunConfig(
+        exclude_external_links=True,
+        preserve_https_for_internal_links=True,  # New in v0.7.5
+        deep_crawl_strategy=BFSDeepCrawlStrategy(
+            max_depth=2,
+            max_pages=5,
+            filter_chain=FilterChain([url_filter])
+        )
+    )
+
+    async with AsyncWebCrawler() as crawler:
+        async for result in await crawler.arun(
+            url="https://quotes.toscrape.com",
+            config=config
+        ):
+            # All internal links maintain HTTPS
+            internal_links = [link['href'] for link in result.links['internal']]
+            https_links = [link for link in internal_links if link.startswith('https://')]
+
+            print(f"HTTPS links preserved: {len(https_links)}/{len(internal_links)}")
+            for link in https_links[:3]:
+                print(f"  → {link}")
+```
+

+# Crawl4AI v0.7.6 Release Notes
+
+*Release Date: October 22, 2025*
+
+I'm excited to announce Crawl4AI v0.7.6, featuring a complete webhook infrastructure for the Docker job queue API! This release eliminates polling and brings real-time notifications to both crawling and LLM extraction workflows.
+
+## 🎯 What's New
+
+### Webhook Support for Docker Job Queue API
+
+The headline feature of v0.7.6 is comprehensive webhook support for asynchronous job processing. No more constant polling to check if your jobs are done - get instant notifications when they complete!
+
+**Key Capabilities:**
+
+- ✅ **Universal Webhook Support**: Both `/crawl/job` and `/llm/job` endpoints now support webhooks
+- ✅ **Flexible Delivery Modes**: Choose notification-only or include full data in the webhook payload
+- ✅ **Reliable Delivery**: Exponential backoff retry mechanism (5 attempts: 1s → 2s → 4s → 8s → 16s)
+- ✅ **Custom Authentication**: Add custom headers for webhook authentication
+- ✅ **Global Configuration**: Set default webhook URL in `config.yml` for all jobs
+- ✅ **Task Type Identification**: Distinguish between `crawl` and `llm_extraction` tasks
+
+### How It Works
+
+Instead of constantly checking job status:
+
+**OLD WAY (Polling):**
+```python
+# Submit job
+response = requests.post("http://localhost:11235/crawl/job", json=payload)
+task_id = response.json()['task_id']
+
+# Poll until complete
+while True:
+    status = requests.get(f"http://localhost:11235/crawl/job/{task_id}")
+    if status.json()['status'] == 'completed':
+        break
+    time.sleep(5)  # Wait and try again
+```
+
+**NEW WAY (Webhooks):**
+```python
+# Submit job with webhook
+payload = {
+    "urls": ["https://example.com"],
+    "webhook_config": {
+        "webhook_url": "https://myapp.com/webhook",
+        "webhook_data_in_payload": True
+    }
+}
+response = requests.post("http://localhost:11235/crawl/job", json=payload)
+
+# Done! Webhook will notify you when complete
+# Your webhook handler receives the results automatically
+```
+
+### Crawl Job Webhooks
+
+```bash
+curl -X POST http://localhost:11235/crawl/job \
+  -H "Content-Type: application/json" \
+  -d '{
+    "urls": ["https://example.com"],
+    "browser_config": {"headless": true},
+    "crawler_config": {"cache_mode": "bypass"},
+    "webhook_config": {
+      "webhook_url": "https://myapp.com/webhooks/crawl-complete",
+      "webhook_data_in_payload": false,
+      "webhook_headers": {
+        "X-Webhook-Secret": "your-secret-token"
+      }
+    }
+  }'
+```
+
+### LLM Extraction Job Webhooks (NEW!)
+
+```bash
+curl -X POST http://localhost:11235/llm/job \
+  -H "Content-Type: application/json" \
+  -d '{
+    "url": "https://example.com/article",
+    "q": "Extract the article title, author, and publication date",
+    "schema": "{\"type\":\"object\",\"properties\":{\"title\":{\"type\":\"string\"}}}",
+    "provider": "openai/gpt-4o-mini",
+    "webhook_config": {
+      "webhook_url": "https://myapp.com/webhooks/llm-complete",
+      "webhook_data_in_payload": true
+    }
+  }'
+```
+
+### Webhook Payload Structure
+
+**Success (with data):**
+```json
+{
+  "task_id": "llm_1698765432",
+  "task_type": "llm_extraction",
+  "status": "completed",
+  "timestamp": "2025-10-22T10:30:00.000000+00:00",
+  "urls": ["https://example.com/article"],
+  "data": {
+    "extracted_content": {
+      "title": "Understanding Web Scraping",
+      "author": "John Doe",
+      "date": "2025-10-22"
+    }
+  }
+}
+```
+
+**Failure:**
+```json
+{
+  "task_id": "crawl_abc123",
+  "task_type": "crawl",
+  "status": "failed",
+  "timestamp": "2025-10-22T10:30:00.000000+00:00",
+  "urls": ["https://example.com"],
+  "error": "Connection timeout after 30s"
+}
+```
+
+### Simple Webhook Handler Example
+
+```python
+from flask import Flask, request, jsonify
+
+app = Flask(__name__)
+
+@app.route('/webhook', methods=['POST'])
+def handle_webhook():
+    payload = request.json
+
+    task_id = payload['task_id']
+    task_type = payload['task_type']
+    status = payload['status']
+
+    if status == 'completed':
+        if 'data' in payload:
+            # Process data directly
+            data = payload['data']
+        else:
+            # Fetch from API
+            endpoint = 'crawl' if task_type == 'crawl' else 'llm'
+            response = requests.get(f'http://localhost:11235/{endpoint}/job/{task_id}')
+            data = response.json()
+
+        # Your business logic here
+        print(f"Job {task_id} completed!")
+
+    elif status == 'failed':
+        error = payload.get('error', 'Unknown error')
+        print(f"Job {task_id} failed: {error}")
+
+    return jsonify({"status": "received"}), 200
+
+app.run(port=8080)
+```
+
+## 📊 Performance Improvements
+
+- **Reduced Server Load**: Eliminates constant polling requests
+- **Lower Latency**: Instant notification vs. polling interval delay
+- **Better Resource Usage**: Frees up client connections while jobs run in background
+- **Scalable Architecture**: Handles high-volume crawling workflows efficiently
+
+## 🐛 Bug Fixes
+
+- Fixed webhook configuration serialization for Pydantic HttpUrl fields
+- Improved error handling in webhook delivery service
+- Enhanced Redis task storage for webhook config persistence
+
+## 🌍 Expected Real-World Impact
+
+### For Web Scraping Workflows
+- **Reduced Costs**: Less API calls = lower bandwidth and server costs
+- **Better UX**: Instant notifications improve user experience
+- **Scalability**: Handle 100s of concurrent jobs without polling overhead
+
+### For LLM Extraction Pipelines
+- **Async Processing**: Submit LLM extraction jobs and move on
+- **Batch Processing**: Queue multiple extractions, get notified as they complete
+- **Integration**: Easy integration with workflow automation tools (Zapier, n8n, etc.)
+
+### For Microservices
+- **Event-Driven**: Perfect for event-driven microservice architectures
+- **Decoupling**: Decouple job submission from result processing
+- **Reliability**: Automatic retries ensure webhooks are delivered
+
+## 🔄 Breaking Changes
+
+**None!** This release is fully backward compatible.
+
+- Webhook configuration is optional
+- Existing code continues to work without modification
+- Polling is still supported for jobs without webhook config
+
+## 📚 Documentation
+
+### New Documentation
+- **[WEBHOOK_EXAMPLES.md](../deploy/docker/WEBHOOK_EXAMPLES.md)** - Comprehensive webhook usage guide
+- **[docker_webhook_example.py](../docs/examples/docker_webhook_example.py)** - Working code examples
+
+### Updated Documentation
+- **[Docker README](../deploy/docker/README.md)** - Added webhook sections
+- API documentation with webhook examples
+
+## 🛠️ Migration Guide
+
+No migration needed! Webhooks are opt-in:
+
+1. **To use webhooks**: Add `webhook_config` to your job payload
+2. **To keep polling**: Continue using your existing code
+
+### Quick Start
+
+```python
+# Just add webhook_config to your existing payload
+payload = {
+    # Your existing configuration
+    "urls": ["https://example.com"],
+    "browser_config": {...},
+    "crawler_config": {...},
+
+    # NEW: Add webhook configuration
+    "webhook_config": {
+        "webhook_url": "https://myapp.com/webhook",
+        "webhook_data_in_payload": True
+    }
+}
+```
+
+## 🔧 Configuration
+
+### Global Webhook Configuration (config.yml)
+
+```yaml
+webhooks:
+  enabled: true
+  default_url: "https://myapp.com/webhooks/default"  # Optional
+  data_in_payload: false
+  retry:
+    max_attempts: 5
+    initial_delay_ms: 1000
+    max_delay_ms: 32000
+    timeout_ms: 30000
+  headers:
+    User-Agent: "Crawl4AI-Webhook/1.0"
+```
+
+## 🚀 Upgrade Instructions
+
+### Docker
+
+```bash
+# Pull the latest image
+docker pull unclecode/crawl4ai:0.7.6
+
+# Or use latest tag
+docker pull unclecode/crawl4ai:latest
+
+# Run with webhook support
+docker run -d \
+  -p 11235:11235 \
+  --env-file .llm.env \
+  --name crawl4ai \
+  unclecode/crawl4ai:0.7.6
+```
+
+### Python Package
+
+```bash
+pip install --upgrade crawl4ai
+```
+
+## 💡 Pro Tips
+
+1. **Use notification-only mode** for large results - fetch data separately to avoid large webhook payloads
+2. **Set custom headers** for webhook authentication and request tracking
+3. **Configure global default webhook** for consistent handling across all jobs
+4. **Implement idempotent webhook handlers** - same webhook may be delivered multiple times on retry
+5. **Use structured schemas** with LLM extraction for predictable webhook data
+

+# 🚀 Crawl4AI v0.7.7: The Self-Hosting & Monitoring Update
+
+*November 14, 2025 • 10 min read*
+
+---
+
+Today I'm releasing Crawl4AI v0.7.7—the Self-Hosting & Monitoring Update. This release transforms Crawl4AI Docker from a simple containerized crawler into a complete self-hosting platform with enterprise-grade real-time monitoring, full operational transparency, and production-ready observability.
+
+## 🎯 What's New at a Glance
+
+- **📊 Real-time Monitoring Dashboard**: Interactive web UI with live system metrics and browser pool status
+- **🔌 Comprehensive Monitor API**: Complete REST API for programmatic access to all monitoring data
+- **⚡ WebSocket Streaming**: Real-time updates every 2 seconds for custom dashboards
+- **🎮 Control Actions**: Manual browser management (kill, restart, cleanup)
+- **🔥 Smart Browser Pool**: 3-tier architecture (permanent/hot/cold) with automatic promotion
+- **🧹 Janitor Cleanup System**: Automatic resource management with event logging
+- **📈 Production Metrics**: 6 critical metrics for operational excellence
+- **🏭 Integration Ready**: Prometheus, alerting, and log aggregation examples
+- **🐛 Critical Bug Fixes**: Async LLM extraction, DFS crawling, viewport config, and more
+
+## 📊 Real-time Monitoring Dashboard: Complete Visibility
+
+**The Problem:** Running Crawl4AI in Docker was like flying blind. Users had no visibility into what was happening inside the container—memory usage, active requests, browser pools, or errors. Troubleshooting required checking logs, and there was no way to monitor performance or manually intervene when issues occurred.
+
+**My Solution:** I built a complete real-time monitoring system with an interactive dashboard, comprehensive REST API, WebSocket streaming, and manual control actions. Now you have full transparency and control over your crawling infrastructure.
+
+### The Self-Hosting Value Proposition
+
+Before v0.7.7, Docker was just a containerized crawler. After v0.7.7, it's a complete self-hosting platform that gives you:
+
+- **🔒 Data Privacy**: Your data never leaves your infrastructure
+- **💰 Cost Control**: No per-request pricing or rate limits
+- **🎯 Full Customization**: Complete control over configurations and strategies
+- **📊 Complete Transparency**: Real-time visibility into every aspect
+- **⚡ Performance**: Direct access without network overhead
+- **🛡️ Enterprise Security**: Keep workflows behind your firewall
+
+### Interactive Monitoring Dashboard
+
+Access the dashboard at `http://localhost:11235/dashboard` to see:
+
+- **System Health Overview**: CPU, memory, network, and uptime in real-time
+- **Live Request Tracking**: Active and completed requests with full details
+- **Browser Pool Management**: Interactive table with permanent/hot/cold browsers
+- **Janitor Events Log**: Automatic cleanup activities
+- **Error Monitoring**: Full context error logs
+
+The dashboard updates every 2 seconds via WebSocket, giving you live visibility into your crawling operations.
+
+## 🔌 Monitor API: Programmatic Access
+
+**The Problem:** Monitoring dashboards are great for humans, but automation and integration require programmatic access.
+
+**My Solution:** A comprehensive REST API that exposes all monitoring data for integration with your existing infrastructure.
+
+### System Health Endpoint
+
+```python
+import httpx
+import asyncio
+
+async def monitor_system_health():
+    async with httpx.AsyncClient() as client:
+        response = await client.get("http://localhost:11235/monitor/health")
+        health = response.json()
+
+        print(f"Container Metrics:")
+        print(f"  CPU: {health['container']['cpu_percent']:.1f}%")
+        print(f"  Memory: {health['container']['memory_percent']:.1f}%")
+        print(f"  Uptime: {health['container']['uptime_seconds']}s")
+
+        print(f"\nBrowser Pool:")
+        print(f"  Permanent: {health['pool']['permanent']['active']} active")
+        print(f"  Hot Pool: {health['pool']['hot']['count']} browsers")
+        print(f"  Cold Pool: {health['pool']['cold']['count']} browsers")
+
+        print(f"\nStatistics:")
+        print(f"  Total Requests: {health['stats']['total_requests']}")
+        print(f"  Success Rate: {health['stats']['success_rate_percent']:.1f}%")
+        print(f"  Avg Latency: {health['stats']['avg_latency_ms']:.0f}ms")
+
+asyncio.run(monitor_system_health())
+```
+
+### Request Tracking
+
+```python
+async def track_requests():
+    async with httpx.AsyncClient() as client:
+        response = await client.get("http://localhost:11235/monitor/requests")
+        requests_data = response.json()
+
+        print(f"Active Requests: {len(requests_data['active'])}")
+        print(f"Completed Requests: {len(requests_data['completed'])}")
+
+        # See details of recent requests
+        for req in requests_data['completed'][:5]:
+            status_icon = "✅" if req['success'] else "❌"
+            print(f"{status_icon} {req['endpoint']} - {req['latency_ms']:.0f}ms")
+```
+
+### Browser Pool Management
+
+```python
+async def monitor_browser_pool():
+    async with httpx.AsyncClient() as client:
+        response = await client.get("http://localhost:11235/monitor/browsers")
+        browsers = response.json()
+
+        print(f"Pool Summary:")
+        print(f"  Total Browsers: {browsers['summary']['total_count']}")
+        print(f"  Total Memory: {browsers['summary']['total_memory_mb']} MB")
+        print(f"  Reuse Rate: {browsers['summary']['reuse_rate_percent']:.1f}%")
+
+        # List all browsers
+        for browser in browsers['permanent']:
+            print(f"🔥 Permanent: {browser['browser_id'][:8]}... | "
+                  f"Requests: {browser['request_count']} | "
+                  f"Memory: {browser['memory_mb']:.0f} MB")
+```
+
+### Endpoint Performance Statistics
+
+```python
+async def get_endpoint_stats():
+    async with httpx.AsyncClient() as client:
+        response = await client.get("http://localhost:11235/monitor/endpoints/stats")
+        stats = response.json()
+
+        print("Endpoint Analytics:")
+        for endpoint, data in stats.items():
+            print(f"  {endpoint}:")
+            print(f"    Requests: {data['count']}")
+            print(f"    Avg Latency: {data['avg_latency_ms']:.0f}ms")
+            print(f"    Success Rate: {data['success_rate_percent']:.1f}%")
+```
+
+### Complete API Reference
+
+The Monitor API includes these endpoints:
+
+- `GET /monitor/health` - System health with pool statistics
+- `GET /monitor/requests` - Active and completed request tracking
+- `GET /monitor/browsers` - Browser pool details and efficiency

+
+## ⚡ WebSocket Streaming: Real-time Updates
+
+**The Problem:** Polling the API every few seconds wastes resources and adds latency. Real-time dashboards need instant updates.
+
+**My Solution:** WebSocket streaming with 2-second update intervals for building custom real-time dashboards.
+
+### WebSocket Integration Example
+
+```python
+import websockets
+import json
+import asyncio
+
+async def monitor_realtime():
+    uri = "ws://localhost:11235/monitor/ws"
+
+    async with websockets.connect(uri) as websocket:
+        print("Connected to real-time monitoring stream")
+
+        while True:
+            # Receive update every 2 seconds
+            data = await websocket.recv()
+            update = json.loads(data)
+
+            # Access all monitoring data
+            print(f"\n--- Update at {update['timestamp']} ---")
+            print(f"Memory: {update['health']['container']['memory_percent']:.1f}%")
+            print(f"Active Requests: {len(update['requests']['active'])}")
+            print(f"Total Browsers: {update['browsers']['summary']['total_count']}")
+
+            if update['errors']:
+                print(f"⚠️  Recent Errors: {len(update['errors'])}")
+
+asyncio.run(monitor_realtime())
+```
+
+**Expected Real-World Impact:**
+- **Custom Dashboards**: Build tailored monitoring UIs for your team
+- **Real-time Alerting**: Trigger alerts instantly when metrics exceed thresholds
+- **Integration**: Feed live data into monitoring tools like Grafana
+- **Automation**: React to events in real-time without polling
+
+## 🔥 Smart Browser Pool: 3-Tier Architecture
+
+**The Problem:** Creating a new browser for every request is slow and memory-intensive. Traditional browser pools are static and inefficient.
+
+**My Solution:** A smart 3-tier browser pool that automatically adapts to usage patterns.
+
+### How It Works
+
+```python
+import httpx
+
+async def demonstrate_browser_pool():
+    async with httpx.AsyncClient() as client:
+        # Request 1-3: Default config → Uses permanent browser
+        print("Phase 1: Using permanent browser")
+        for i in range(3):
+            await client.post(
+                "http://localhost:11235/crawl",
+                json={"urls": [f"https://httpbin.org/html?req={i}"]}
+            )
+            print(f"  Request {i+1}: Reused permanent browser")
+
+        # Request 4-6: Custom viewport → Cold pool (first use)
+        print("\nPhase 2: Custom config creates cold pool browser")
+        viewport_config = {"viewport": {"width": 1280, "height": 720}}
+        for i in range(4):
+            await client.post(
+                "http://localhost:11235/crawl",
+                json={
+                    "urls": [f"https://httpbin.org/json?v={i}"],
+                    "browser_config": viewport_config
+                }
+            )
+            if i < 2:
+                print(f"  Request {i+1}: Cold pool browser")
+            else:
+                print(f"  Request {i+1}: Promoted to hot pool! (after 3 uses)")
+
+        # Check pool status
+        response = await client.get("http://localhost:11235/monitor/browsers")
+        browsers = response.json()
+
+        print(f"\nPool Status:")
+        print(f"  Permanent: {len(browsers['permanent'])} (always active)")
+        print(f"  Hot: {len(browsers['hot'])} (frequently used configs)")
+        print(f"  Cold: {len(browsers['cold'])} (on-demand)")
+        print(f"  Reuse Rate: {browsers['summary']['reuse_rate_percent']:.1f}%")
+
+asyncio.run(demonstrate_browser_pool())
+```
+
+**Pool Tiers:**
+
+- **🔥 Permanent Browser**: Always-on, default configuration, instant response
+- **♨️ Hot Pool**: Browsers promoted after 3+ uses, kept warm for quick access
+- **❄️ Cold Pool**: On-demand browsers for variant configs, cleaned up when idle
+
+**Expected Real-World Impact:**
+- **Memory Efficiency**: 10x reduction in memory usage vs creating browsers per request
+- **Performance**: Instant access to frequently-used configurations
+- **Automatic Optimization**: Pool adapts to your usage patterns
+- **Resource Management**: Janitor automatically cleans up idle browsers
+
+## 🧹 Janitor System: Automatic Cleanup
+
+**The Problem:** Long-running crawlers accumulate idle browsers and consume memory over time.
+
+**My Solution:** An automatic janitor system that monitors and cleans up idle resources.
+
+```python
+async def monitor_janitor_activity():
+    async with httpx.AsyncClient() as client:
+        response = await client.get("http://localhost:11235/monitor/logs/janitor?limit=5")
+        logs = response.json()
+
+        print("Recent Cleanup Activities:")
+        for log in logs:
+            print(f"  {log['timestamp']}: {log['message']}")
+
+# Example output:
+# 2025-11-14 10:30:00: Cleaned up 2 cold pool browsers (idle > 5min)
+# 2025-11-14 10:25:00: Browser reuse rate: 85.3%
+# 2025-11-14 10:20:00: Hot pool browser promoted (10 requests)
+```
+
+## 🎮 Control Actions: Manual Management
+
+**The Problem:** Sometimes you need to manually intervene—kill a stuck browser, force cleanup, or restart resources.
+
+**My Solution:** Manual control actions via the API for operational troubleshooting.
+
+### Force Cleanup
+
+```python
+async def force_cleanup():
+    async with httpx.AsyncClient() as client:
+        response = await client.post("http://localhost:11235/monitor/actions/cleanup")
+        result = response.json()
+
+        print(f"Cleanup completed:")
+        print(f"  Browsers cleaned: {result.get('cleaned_count', 0)}")
+        print(f"  Memory freed: {result.get('memory_freed_mb', 0):.1f} MB")
+```
+
+### Kill Specific Browser
+
+```python
+async def kill_stuck_browser(browser_id: str):
+    async with httpx.AsyncClient() as client:
+        response = await client.post(
+            "http://localhost:11235/monitor/actions/kill_browser",
+            json={"browser_id": browser_id}
+        )
+
+        if response.status_code == 200:
+            print(f"✅ Browser {browser_id} killed successfully")
+```
+
+### Reset Statistics
+
+```python
+async def reset_stats():
+    async with httpx.AsyncClient() as client:
+        response = await client.post("http://localhost:11235/monitor/stats/reset")
+        print("📊 Statistics reset for fresh monitoring")
+```
+
+## 📈 Production Integration Patterns
+
+### Prometheus Integration
+
+```python
+# Export metrics for Prometheus scraping
+async def export_prometheus_metrics():
+    async with httpx.AsyncClient() as client:
+        health = await client.get("http://localhost:11235/monitor/health")
+        data = health.json()
+
+        # Export in Prometheus format
+        metrics = f"""
+# HELP crawl4ai_memory_usage_percent Memory usage percentage
+# TYPE crawl4ai_memory_usage_percent gauge
+crawl4ai_memory_usage_percent {data['container']['memory_percent']}
+
+# HELP crawl4ai_request_success_rate Request success rate
+# TYPE crawl4ai_request_success_rate gauge
+crawl4ai_request_success_rate {data['stats']['success_rate_percent']}
+
+# HELP crawl4ai_browser_pool_count Total browsers in pool
+# TYPE crawl4ai_browser_pool_count gauge
+crawl4ai_browser_pool_count {data['pool']['permanent']['active'] + data['pool']['hot']['count'] + data['pool']['cold']['count']}
+"""
+        return metrics
+```
+
+### Alerting Example
+
+```python
+async def check_alerts():
+    async with httpx.AsyncClient() as client:
+        health = await client.get("http://localhost:11235/monitor/health")
+        data = health.json()
+
+        # Memory alert
+        if data['container']['memory_percent'] > 80:
+            print("🚨 ALERT: Memory usage above 80%")
+            # Trigger cleanup
+            await client.post("http://localhost:11235/monitor/actions/cleanup")
+
+        # Success rate alert
+        if data['stats']['success_rate_percent'] < 90:
+            print("🚨 ALERT: Success rate below 90%")
+            # Check error logs
+            errors = await client.get("http://localhost:11235/monitor/logs/errors")
+            print(f"Recent errors: {len(errors.json())}")
+
+        # Latency alert
+        if data['stats']['avg_latency_ms'] > 5000:
+            print("🚨 ALERT: Average latency above 5s")
+```
+
+### Key Metrics to Track
+
+```python
+CRITICAL_METRICS = {
+    "memory_usage": {
+        "current": "container.memory_percent",
+        "target": "<80%",
+        "alert_threshold": ">80%",
+        "action": "Force cleanup or scale"
+    },
+    "success_rate": {
+        "current": "stats.success_rate_percent",
+        "target": ">95%",
+        "alert_threshold": "<90%",
+        "action": "Check error logs"
+    },
+    "avg_latency": {
+        "current": "stats.avg_latency_ms",
+        "target": "<2000ms",
+        "alert_threshold": ">5000ms",
+        "action": "Investigate slow requests"
+    },
+    "browser_reuse_rate": {
+        "current": "browsers.summary.reuse_rate_percent",
+        "target": ">80%",
+        "alert_threshold": "<60%",
+        "action": "Check pool configuration"
+    },
+    "total_browsers": {

+        "target": "<15",
+        "alert_threshold": ">20",
+        "action": "Check for browser leaks"
+    },
+    "error_frequency": {
+        "current": "len(errors)",
+        "target": "<5/hour",
+        "alert_threshold": ">10/hour",
+        "action": "Review error patterns"
+    }
+}
+```
+
+## 🐛 Critical Bug Fixes
+
+This release includes significant bug fixes that improve stability and performance:
+
+### Async LLM Extraction (#1590)
+
+**The Problem:** LLM extraction was blocking async execution, causing URLs to be processed sequentially instead of in parallel (issue #1055).
+
+**The Fix:** Resolved the blocking issue to enable true parallel processing for LLM extraction.
+
+```python
+# Before v0.7.7: Sequential processing
+# After v0.7.7: True parallel processing
+
+async with AsyncWebCrawler() as crawler:
+    urls = ["url1", "url2", "url3", "url4"]
+
+    # Now processes truly in parallel with LLM extraction
+    results = await crawler.arun_many(
+        urls,
+        config=CrawlerRunConfig(
+            extraction_strategy=LLMExtractionStrategy(...)
+        )
+    )
+    # 4x faster for parallel LLM extraction!
+```
+
+**Expected Impact:** Major performance improvement for batch LLM extraction workflows.
+
+### DFS Deep Crawling (#1607)
+
+**The Problem:** DFS (Depth-First Search) deep crawl strategy had implementation issues.
+
+**The Fix:** Enhanced DFSDeepCrawlStrategy with proper seen URL tracking and improved documentation.
+
+### Browser & Crawler Config Documentation (#1609)
+
+**The Problem:** Documentation didn't match the actual `async_configs.py` implementation.
+
+**The Fix:** Updated all configuration documentation to accurately reflect the current implementation.
+
+### Sitemap Seeder (#1598)
+
+**The Problem:** Sitemap parsing and URL normalization issues in AsyncUrlSeeder (issue #1559).
+
+**The Fix:** Added comprehensive tests and fixes for sitemap namespace parsing and URL normalization.
+
+### Remove Overlay Elements (#1529)
+
+**The Problem:** The `remove_overlay_elements` functionality wasn't working (issue #1396).
+
+**The Fix:** Fixed by properly calling the injected JavaScript function.
+
+### Viewport Configuration (#1495)
+
+**The Problem:** Viewport configuration wasn't working in managed browsers (issue #1490).
+
+**The Fix:** Added proper viewport size configuration support for browser launch.
+
+### Managed Browser CDP Timing (#1528)
+
+**The Problem:** CDP (Chrome DevTools Protocol) endpoint verification had timing issues causing connection failures (issue #1445).
+
+**The Fix:** Added exponential backoff for CDP endpoint verification to handle timing variations.

+Docker Webhook Example for Crawl4AI
+
+This example demonstrates how to use webhooks with the Crawl4AI job queue API.
+Instead of polling for results, webhooks notify your application when jobs complete.
+
+Supports both:
+- /crawl/job - Raw crawling with markdown extraction
+- /llm/job - LLM-powered content extraction
+
+Prerequisites:
+1. Crawl4AI Docker container running on localhost:11235
+2. Flask installed: pip install flask requests
+3. LLM API key configured in .llm.env (for LLM extraction examples)
+
+Usage:

+### Creating a Profile Using the Crawl4AI CLI (Easiest)
+
+If you prefer a guided, interactive setup, use the built-in CLI to create and manage persistent browser profiles.
+
+1.⠀Launch the profile manager:
+   ```bash
+   crwl profiles
+   ```
+
+2.⠀Choose "Create new profile" and enter a profile name. A Chromium window opens so you can log in to sites and configure settings. When finished, return to the terminal and press `q` to save the profile.
+
+3.⠀Profiles are saved under `~/.crawl4ai/profiles/<profile_name>` (for example: `/home/<you>/.crawl4ai/profiles/test_profile_1`) along with a `storage_state.json` for cookies and session data.
+
+4.⠀Optionally, choose "List profiles" in the CLI to view available profiles and their paths.
+
+5.⠀Use the saved path with `BrowserConfig.user_data_dir`:
+   ```python
+   from crawl4ai import AsyncWebCrawler, BrowserConfig
+
+   profile_path = "/home/<you>/.crawl4ai/profiles/test_profile_1"
+
+   browser_config = BrowserConfig(
+       headless=True,
+       use_managed_browser=True,
+       user_data_dir=profile_path,
+       browser_type="chromium",
+   )
+
+   async with AsyncWebCrawler(config=browser_config) as crawler:
+       result = await crawler.arun(url="https://example.com/private")
+   ```
+
+The CLI also supports listing and deleting profiles, and even testing a crawl directly from the menu.

-# Proxy 
+# Proxy & Security
+
+This guide covers proxy configuration and security features in Crawl4AI, including SSL certificate analysis and proxy rotation strategies.
+
+## Understanding Proxy Configuration
+
+Crawl4AI recommends configuring proxies per request through `CrawlerRunConfig.proxy_config`. This gives you precise control, enables rotation strategies, and keeps examples simple enough to copy, paste, and run.
 
 ## Basic Proxy Setup
 
-Simple proxy configuration with `BrowserConfig`:
+Configure proxies that apply to each crawl operation:
 
 ```python
-from crawl4ai.async_configs import BrowserConfig
-
-# Using HTTP proxy
-browser_config = BrowserConfig(proxy_config={"server": "http://proxy.example.com:8080"})
-async with AsyncWebCrawler(config=browser_config) as crawler:
-    result = await crawler.arun(url="https://example.com")
-
-# Using SOCKS proxy
-browser_config = BrowserConfig(proxy_config={"server": "socks5://proxy.example.com:1080"})
-async with AsyncWebCrawler(config=browser_config) as crawler:
-    result = await crawler.arun(url="https://example.com")
-```
-
-## Authenticated Proxy
-
-Use an authenticated proxy with `BrowserConfig`:
-
-```python
-from crawl4ai.async_configs import BrowserConfig
-
-browser_config = BrowserConfig(proxy_config={
-    "server": "http://[host]:[port]",
-    "username": "[username]",
-    "password": "[password]",
-})
-async with AsyncWebCrawler(config=browser_config) as crawler:
-    result = await crawler.arun(url="https://example.com")
-```
-
-
-## Rotating Proxies 
-
-Example using a proxy rotation service dynamically:
-
-```python
-import re
-from crawl4ai import (
-    AsyncWebCrawler,
-    BrowserConfig,
-    CrawlerRunConfig,
-    CacheMode,
-    RoundRobinProxyStrategy,
-)
 import asyncio
-from crawl4ai import ProxyConfig
+from crawl4ai import AsyncWebCrawler, BrowserConfig, CrawlerRunConfig, ProxyConfig
+
+run_config = CrawlerRunConfig(proxy_config=ProxyConfig(server="http://proxy.example.com:8080"))
+# run_config = CrawlerRunConfig(proxy_config={"server": "http://proxy.example.com:8080"})
+# run_config = CrawlerRunConfig(proxy_config="http://proxy.example.com:8080")
+
+
 async def main():
-    # Load proxies and create rotation strategy
+    browser_config = BrowserConfig()
+    async with AsyncWebCrawler(config=browser_config) as crawler:
+        result = await crawler.arun(url="https://example.com", config=run_config)
+        print(f"Success: {result.success} -> {result.url}")
+
+
+if __name__ == "__main__":
+    asyncio.run(main())
+```
+
+!!! note "Why request-level?"
+    `CrawlerRunConfig.proxy_config` keeps each request self-contained, so swapping proxies or rotation strategies is just a matter of building a new run configuration.
+
+## Supported Proxy Formats
+
+The `ProxyConfig.from_string()` method supports multiple formats:
+
+```python
+from crawl4ai import ProxyConfig
+
+# HTTP proxy with authentication
+proxy1 = ProxyConfig.from_string("http://user:pass@192.168.1.1:8080")
+
+# HTTPS proxy
+proxy2 = ProxyConfig.from_string("https://proxy.example.com:8080")
+
+# SOCKS5 proxy
+proxy3 = ProxyConfig.from_string("socks5://proxy.example.com:1080")
+
+# Simple IP:port format
+proxy4 = ProxyConfig.from_string("192.168.1.1:8080")
+
+# IP:port:user:pass format
+proxy5 = ProxyConfig.from_string("192.168.1.1:8080:user:pass")
+```
+
+## Authenticated Proxies
+
+For proxies requiring authentication:
+
+```python
+import asyncio
+from crawl4ai import AsyncWebCrawler,BrowserConfig, CrawlerRunConfig, ProxyConfig
+
+run_config = CrawlerRunConfig(
+    proxy_config=ProxyConfig(
+        server="http://proxy.example.com:8080",
+        username="your_username",
+        password="your_password",
+    )
+)
+# Or dictionary style:
+# run_config = CrawlerRunConfig(proxy_config={
+#     "server": "http://proxy.example.com:8080",
+#     "username": "your_username",
+#     "password": "your_password",
+# })
+
+
+async def main():
+    browser_config = BrowserConfig()
+    async with AsyncWebCrawler(config=browser_config) as crawler:
+        result = await crawler.arun(url="https://example.com", config=run_config)
+        print(f"Success: {result.success} -> {result.url}")
+
+
+if __name__ == "__main__":
+    asyncio.run(main())
+```
+
+## Environment Variable Configuration
+
+Load proxies from environment variables for easy configuration:
+
+```python
+import os
+from crawl4ai import ProxyConfig, CrawlerRunConfig
+
+# Set environment variable
+os.environ["PROXIES"] = "ip1:port1:user1:pass1,ip2:port2:user2:pass2,ip3:port3"
+
+# Load all proxies
+proxies = ProxyConfig.from_env()
+print(f"Loaded {len(proxies)} proxies")
+
+# Use first proxy
+if proxies:
+    run_config = CrawlerRunConfig(proxy_config=proxies[0])
+```
+
+## Rotating Proxies
+
+Crawl4AI supports automatic proxy rotation to distribute requests across multiple proxy servers. Rotation is applied per request using a rotation strategy on `CrawlerRunConfig`.
+
+### Proxy Rotation (recommended)
+```python
+import asyncio
+import re
+from crawl4ai import AsyncWebCrawler, BrowserConfig, CrawlerRunConfig, CacheMode, ProxyConfig
+from crawl4ai.proxy_strategy import RoundRobinProxyStrategy
+
+async def main():
+    # Load proxies from environment
     proxies = ProxyConfig.from_env()
-    #eg: export PROXIES="ip1:port1:username1:password1,ip2:port2:username2:password2"
     if not proxies:
-        print("No proxies found in environment. Set PROXIES env variable!")
+        print("No proxies found! Set PROXIES environment variable.")
         return
 
+    # Create rotation strategy
     proxy_strategy = RoundRobinProxyStrategy(proxies)
 
-    # Create configs
+    # Configure per-request with proxy rotation
     browser_config = BrowserConfig(headless=True, verbose=False)
     run_config = CrawlerRunConfig(
         cache_mode=CacheMode.BYPASS,
-        proxy_rotation_strategy=proxy_strategy
+        proxy_rotation_strategy=proxy_strategy,
     )
 
     async with AsyncWebCrawler(config=browser_config) as crawler:
         urls = ["https://httpbin.org/ip"] * (len(proxies) * 2)  # Test each proxy twice
 
-        print("\n📈 Initializing crawler with proxy rotation...")
-        async with AsyncWebCrawler(config=browser_config) as crawler:
-            print("\n🚀 Starting batch crawl with proxy rotation...")
-            results = await crawler.arun_many(
-                urls=urls,
-                config=run_config
-            )
-            for result in results:
-                if result.success:

-                    current_proxy = run_config.proxy_config if run_config.proxy_config else None
+        print(f"🚀 Testing {len(proxies)} proxies with rotation...")
+        results = await crawler.arun_many(urls=urls, config=run_config)
 
-                    if current_proxy and ip_match:
-                        print(f"URL {result.url}")
-                        print(f"Proxy {current_proxy.server} -> Response IP: {ip_match.group(0)}")
-                        verified = ip_match.group(0) == current_proxy.ip
-                        if verified:
-                            print(f"✅ Proxy working! IP matches: {current_proxy.ip}")
-                        else:
-                            print("❌ Proxy failed or IP mismatch!")
-                    print("---")
+        for i, result in enumerate(results):
+            if result.success:
+                # Extract IP from response
+                ip_match = re.search(r'(?:[0-9]{1,3}\.){3}[0-9]{1,3}', result.html)
+                if ip_match:
+                    detected_ip = ip_match.group(0)
+                    proxy_index = i % len(proxies)
+                    expected_ip = proxies[proxy_index].ip
 
-asyncio.run(main())
+                    print(f"✅ Request {i+1}: Proxy {proxy_index+1} -> IP {detected_ip}")
+                    if detected_ip == expected_ip:
+                        print("   🎯 IP matches proxy configuration")
+                    else:
+                        print(f"   ⚠️  IP mismatch (expected {expected_ip})")
+                else:
+                    print(f"❌ Request {i+1}: Could not extract IP from response")
+            else:
+                print(f"❌ Request {i+1}: Failed - {result.error_message}")
 
+if __name__ == "__main__":
+    asyncio.run(main())
 ```
 
+## SSL Certificate Analysis
+
+Combine proxy usage with SSL certificate inspection for enhanced security analysis. SSL certificate fetching is configured per request via `CrawlerRunConfig`.
+
+### Per-Request SSL Certificate Analysis
+```python
+import asyncio
+from crawl4ai import AsyncWebCrawler, BrowserConfig, CrawlerRunConfig
+
+run_config = CrawlerRunConfig(
+    proxy_config={
+        "server": "http://proxy.example.com:8080",
+        "username": "user",
+        "password": "pass",
+    },
+    fetch_ssl_certificate=True,  # Enable SSL certificate analysis for this request
+)
+
+
+async def main():
+    browser_config = BrowserConfig()
+    async with AsyncWebCrawler(config=browser_config) as crawler:
+        result = await crawler.arun(url="https://example.com", config=run_config)
+
+        if result.success:
+            print(f"✅ Crawled via proxy: {result.url}")
+
+            # Analyze SSL certificate
+            if result.ssl_certificate:
+                cert = result.ssl_certificate
+                print("🔒 SSL Certificate Info:")
+                print(f"   Issuer: {cert.issuer}")
+                print(f"   Subject: {cert.subject}")
+                print(f"   Valid until: {cert.valid_until}")
+                print(f"   Fingerprint: {cert.fingerprint}")
+
+                # Export certificate
+                cert.to_json("certificate.json")
+                print("💾 Certificate exported to certificate.json")
+            else:
+                print("⚠️  No SSL certificate information available")
+
+
+if __name__ == "__main__":
+    asyncio.run(main())
+```
+
+## Security Best Practices
+
+### 1. Proxy Rotation for Anonymity
+```python
+from crawl4ai import CrawlerRunConfig, ProxyConfig
+from crawl4ai.proxy_strategy import RoundRobinProxyStrategy
+
+# Use multiple proxies to avoid IP blocking
+proxies = ProxyConfig.from_env("PROXIES")
+strategy = RoundRobinProxyStrategy(proxies)
+
+# Configure rotation per request (recommended)
+run_config = CrawlerRunConfig(proxy_rotation_strategy=strategy)
+
+# For a fixed proxy across all requests, just reuse the same run_config instance
+static_run_config = run_config
+```
+
+### 2. SSL Certificate Verification
+```python
+from crawl4ai import CrawlerRunConfig
+
+# Always verify SSL certificates when possible
+# Per-request (affects specific requests)
+run_config = CrawlerRunConfig(fetch_ssl_certificate=True)
+```
+
+### 3. Environment Variable Security
+```bash
+# Use environment variables for sensitive proxy credentials
+# Avoid hardcoding usernames/passwords in code
+export PROXIES="ip1:port1:user1:pass1,ip2:port2:user2:pass2"
+```
+
+### 4. SOCKS5 for Enhanced Security
+```python
+from crawl4ai import CrawlerRunConfig
+
+# Prefer SOCKS5 proxies for better protocol support
+run_config = CrawlerRunConfig(proxy_config="socks5://proxy.example.com:1080")
+```
+
+## Migration from Deprecated `proxy` Parameter
+
+- "Deprecation Notice"
+    The legacy `proxy` argument on `BrowserConfig` is deprecated. Configure proxies through `CrawlerRunConfig.proxy_config` so each request fully describes its network settings.
+
+```python
+# Old (deprecated) approach
+# from crawl4ai import BrowserConfig
+# browser_config = BrowserConfig(proxy="http://proxy.example.com:8080")
+
+# New (preferred) approach
+from crawl4ai import CrawlerRunConfig
+run_config = CrawlerRunConfig(proxy_config="http://proxy.example.com:8080")
+```
+
+### Safe Logging of Proxies
+```python
+from crawl4ai import ProxyConfig
+
+def safe_proxy_repr(proxy: ProxyConfig):
+    if getattr(proxy, "username", None):
+        return f"{proxy.server} (auth: ****)"
+    return proxy.server
+```
+
+## Troubleshooting
+
+### Common Issues
+
+- "Proxy connection failed"
+    - Verify the proxy server is reachable from your network.
+    - Double-check authentication credentials.
+    - Ensure the protocol matches (`http`, `https`, or `socks5`).
+
+- "SSL certificate errors"
+    - Some proxies break SSL inspection; switch proxies if you see repeated failures.
+    - Consider temporarily disabling certificate fetching to isolate the issue.
+
+- "Environment variables not loading"
+    - Confirm `PROXIES` (or your custom env var) is set before running the script.
+    - Check formatting: `ip:port:user:pass,ip:port:user:pass`.
+
+- "Proxy rotation not working"
+    - Ensure `ProxyConfig.from_env()` actually loaded entries (`len(proxies) > 0`).
+    - Attach `proxy_rotation_strategy` to `CrawlerRunConfig`.
+    - Validate the proxy definitions you pass into the strategy.

+# Crawl4AI v0.7.6 Release Notes
+
+*Release Date: October 22, 2025*
+
+I'm excited to announce Crawl4AI v0.7.6, featuring a complete webhook infrastructure for the Docker job queue API! This release eliminates polling and brings real-time notifications to both crawling and LLM extraction workflows.
+
+## 🎯 What's New
+
+### Webhook Support for Docker Job Queue API
+
+The headline feature of v0.7.6 is comprehensive webhook support for asynchronous job processing. No more constant polling to check if your jobs are done - get instant notifications when they complete!
+
+**Key Capabilities:**
+
+- ✅ **Universal Webhook Support**: Both `/crawl/job` and `/llm/job` endpoints now support webhooks
+- ✅ **Flexible Delivery Modes**: Choose notification-only or include full data in the webhook payload
+- ✅ **Reliable Delivery**: Exponential backoff retry mechanism (5 attempts: 1s → 2s → 4s → 8s → 16s)
+- ✅ **Custom Authentication**: Add custom headers for webhook authentication
+- ✅ **Global Configuration**: Set default webhook URL in `config.yml` for all jobs
+- ✅ **Task Type Identification**: Distinguish between `crawl` and `llm_extraction` tasks
+
+### How It Works
+
+Instead of constantly checking job status:
+
+**OLD WAY (Polling):**
+```python
+# Submit job
+response = requests.post("http://localhost:11235/crawl/job", json=payload)
+task_id = response.json()['task_id']
+
+# Poll until complete
+while True:
+    status = requests.get(f"http://localhost:11235/crawl/job/{task_id}")
+    if status.json()['status'] == 'completed':
+        break
+    time.sleep(5)  # Wait and try again
+```
+
+**NEW WAY (Webhooks):**
+```python
+# Submit job with webhook
+payload = {
+    "urls": ["https://example.com"],
+    "webhook_config": {
+        "webhook_url": "https://myapp.com/webhook",
+        "webhook_data_in_payload": True
+    }
+}
+response = requests.post("http://localhost:11235/crawl/job", json=payload)
+
+# Done! Webhook will notify you when complete
+# Your webhook handler receives the results automatically
+```
+
+### Crawl Job Webhooks
+
+```bash
+curl -X POST http://localhost:11235/crawl/job \
+  -H "Content-Type: application/json" \
+  -d '{
+    "urls": ["https://example.com"],
+    "browser_config": {"headless": true},
+    "crawler_config": {"cache_mode": "bypass"},
+    "webhook_config": {
+      "webhook_url": "https://myapp.com/webhooks/crawl-complete",
+      "webhook_data_in_payload": false,
+      "webhook_headers": {
+        "X-Webhook-Secret": "your-secret-token"
+      }
+    }
+  }'
+```
+
+### LLM Extraction Job Webhooks (NEW!)
+
+```bash
+curl -X POST http://localhost:11235/llm/job \
+  -H "Content-Type: application/json" \
+  -d '{
+    "url": "https://example.com/article",
+    "q": "Extract the article title, author, and publication date",
+    "schema": "{\"type\":\"object\",\"properties\":{\"title\":{\"type\":\"string\"}}}",
+    "provider": "openai/gpt-4o-mini",
+    "webhook_config": {
+      "webhook_url": "https://myapp.com/webhooks/llm-complete",
+      "webhook_data_in_payload": true
+    }
+  }'
+```
+
+### Webhook Payload Structure
+
+**Success (with data):**
+```json
+{
+  "task_id": "llm_1698765432",
+  "task_type": "llm_extraction",
+  "status": "completed",
+  "timestamp": "2025-10-22T10:30:00.000000+00:00",
+  "urls": ["https://example.com/article"],
+  "data": {
+    "extracted_content": {
+      "title": "Understanding Web Scraping",
+      "author": "John Doe",
+      "date": "2025-10-22"
+    }
+  }
+}
+```
+
+**Failure:**
+```json
+{
+  "task_id": "crawl_abc123",
+  "task_type": "crawl",
+  "status": "failed",
+  "timestamp": "2025-10-22T10:30:00.000000+00:00",
+  "urls": ["https://example.com"],
+  "error": "Connection timeout after 30s"
+}
+```
+
+### Simple Webhook Handler Example
+
+```python
+from flask import Flask, request, jsonify
+
+app = Flask(__name__)
+
+@app.route('/webhook', methods=['POST'])
+def handle_webhook():
+    payload = request.json
+
+    task_id = payload['task_id']
+    task_type = payload['task_type']
+    status = payload['status']
+
+    if status == 'completed':
+        if 'data' in payload:
+            # Process data directly
+            data = payload['data']
+        else:
+            # Fetch from API
+            endpoint = 'crawl' if task_type == 'crawl' else 'llm'
+            response = requests.get(f'http://localhost:11235/{endpoint}/job/{task_id}')
+            data = response.json()
+
+        # Your business logic here
+        print(f"Job {task_id} completed!")
+
+    elif status == 'failed':
+        error = payload.get('error', 'Unknown error')
+        print(f"Job {task_id} failed: {error}")
+
+    return jsonify({"status": "received"}), 200
+
+app.run(port=8080)
+```

+
+## 🛠️ Migration Guide
+
+No migration needed! Webhooks are opt-in:
+
+1. **To use webhooks**: Add `webhook_config` to your job payload
+2. **To keep polling**: Continue using your existing code
+
+### Quick Start
+
+```python
+# Just add webhook_config to your existing payload
+payload = {
+    # Your existing configuration
+    "urls": ["https://example.com"],
+    "browser_config": {...},
+    "crawler_config": {...},
+
+    # NEW: Add webhook configuration
+    "webhook_config": {
+        "webhook_url": "https://myapp.com/webhook",
+        "webhook_data_in_payload": True
+    }
+}
+```
+
+## 🔧 Configuration
+
+### Global Webhook Configuration (config.yml)
+
+```yaml
+webhooks:
+  enabled: true
+  default_url: "https://myapp.com/webhooks/default"  # Optional
+  data_in_payload: false
+  retry:
+    max_attempts: 5
+    initial_delay_ms: 1000
+    max_delay_ms: 32000
+    timeout_ms: 30000
+  headers:
+    User-Agent: "Crawl4AI-Webhook/1.0"
+```
+
+## 🚀 Upgrade Instructions
+
+### Docker
+
+```bash
+# Pull the latest image
+docker pull unclecode/crawl4ai:0.7.6
+
+# Or use latest tag
+docker pull unclecode/crawl4ai:latest
+
+# Run with webhook support
+docker run -d \
+  -p 11235:11235 \
+  --env-file .llm.env \
+  --name crawl4ai \
+  unclecode/crawl4ai:0.7.6
+```
+
+### Python Package
+
+```bash
+pip install --upgrade crawl4ai
+```
+
+## 💡 Pro Tips
+
+1. **Use notification-only mode** for large results - fetch data separately to avoid large webhook payloads
+2. **Set custom headers** for webhook authentication and request tracking
+3. **Configure global default webhook** for consistent handling across all jobs
+4. **Implement idempotent webhook handlers** - same webhook may be delivered multiple times on retry
+5. **Use structured schemas** with LLM extraction for predictable webhook data

+# 🚀 Crawl4AI v0.7.5: The Docker Hooks & Security Update
+
+*September 29, 2025 • 8 min read*
+
+---
+
+Today I'm releasing Crawl4AI v0.7.5—focused on extensibility and security. This update introduces the Docker Hooks System for pipeline customization, enhanced LLM integration, and important security improvements.
+
+## 🎯 What's New at a Glance
+
+- **Docker Hooks System**: Custom Python functions at key pipeline points with function-based API
+- **Function-Based Hooks**: New `hooks_to_string()` utility with Docker client auto-conversion
+- **Enhanced LLM Integration**: Custom providers with temperature control
+- **HTTPS Preservation**: Secure internal link handling
+- **Bug Fixes**: Resolved multiple community-reported issues
+- **Improved Docker Error Handling**: Better debugging and reliability
+
+## 🔧 Docker Hooks System: Pipeline Customization
+
+Every scraping project needs custom logic—authentication, performance optimization, content processing. Traditional solutions require forking or complex workarounds. Docker Hooks let you inject custom Python functions at 8 key points in the crawling pipeline.
+
+### Real Example: Authentication & Performance
+
+```python
+import requests
+
+# Real working hooks for httpbin.org
+hooks_config = {
+    "on_page_context_created": """
+async def hook(page, context, **kwargs):
+    print("Hook: Setting up page context")
+    # Block images to speed up crawling
+    await context.route("**/*.{png,jpg,jpeg,gif,webp}", lambda route: route.abort())
+    print("Hook: Images blocked")
+    return page
+""",
+
+    "before_retrieve_html": """
+async def hook(page, context, **kwargs):
+    print("Hook: Before retrieving HTML")
+    # Scroll to bottom to load lazy content
+    await page.evaluate("window.scrollTo(0, document.body.scrollHeight)")
+    await page.wait_for_timeout(1000)
+    print("Hook: Scrolled to bottom")
+    return page
+""",
+
+    "before_goto": """
+async def hook(page, context, url, **kwargs):
+    print(f"Hook: About to navigate to {url}")
+    # Add custom headers
+    await page.set_extra_http_headers({
+        'X-Test-Header': 'crawl4ai-hooks-test'
+    })
+    return page
+"""
+}
+
+# Test with Docker API
+payload = {
+    "urls": ["https://httpbin.org/html"],
+    "hooks": {
+        "code": hooks_config,
+        "timeout": 30
+    }
+}
+
+response = requests.post("http://localhost:11235/crawl", json=payload)
+result = response.json()
+
+if result.get('success'):
+    print("✅ Hooks executed successfully!")
+    print(f"Content length: {len(result.get('markdown', ''))} characters")
+```
+
+**Available Hook Points:**
+- `on_browser_created`: Browser setup
+- `on_page_context_created`: Page context configuration
+- `before_goto`: Pre-navigation setup
+- `after_goto`: Post-navigation processing
+- `on_user_agent_updated`: User agent changes
+- `on_execution_started`: Crawl initialization
+- `before_retrieve_html`: Pre-extraction processing
+- `before_return_html`: Final HTML processing
+
+### Function-Based Hooks API
+
+Writing hooks as strings works, but lacks IDE support and type checking. v0.7.5 introduces a function-based approach with automatic conversion!
+
+**Option 1: Using the `hooks_to_string()` Utility**
+
+```python
+from crawl4ai import hooks_to_string
+import requests
+
+# Define hooks as regular Python functions (with full IDE support!)
+async def on_page_context_created(page, context, **kwargs):
+    """Block images to speed up crawling"""
+    await context.route("**/*.{png,jpg,jpeg,gif,webp}", lambda route: route.abort())
+    await page.set_viewport_size({"width": 1920, "height": 1080})
+    return page
+
+async def before_goto(page, context, url, **kwargs):
+    """Add custom headers"""
+    await page.set_extra_http_headers({
+        'X-Crawl4AI': 'v0.7.5',
+        'X-Custom-Header': 'my-value'
+    })
+    return page
+
+# Convert functions to strings
+hooks_code = hooks_to_string({
+    "on_page_context_created": on_page_context_created,
+    "before_goto": before_goto
+})
+
+# Use with REST API
+payload = {
+    "urls": ["https://httpbin.org/html"],
+    "hooks": {"code": hooks_code, "timeout": 30}
+}
+response = requests.post("http://localhost:11235/crawl", json=payload)
+```
+
+**Option 2: Docker Client with Automatic Conversion (Recommended!)**
+
+```python
+from crawl4ai.docker_client import Crawl4aiDockerClient
+
+# Define hooks as functions (same as above)
+async def on_page_context_created(page, context, **kwargs):
+    await context.route("**/*.{png,jpg,jpeg,gif,webp}", lambda route: route.abort())
+    return page
+
+async def before_retrieve_html(page, context, **kwargs):
+    # Scroll to load lazy content
+    await page.evaluate("window.scrollTo(0, document.body.scrollHeight)")
+    await page.wait_for_timeout(1000)
+    return page
+
+# Use Docker client - conversion happens automatically!
+client = Crawl4aiDockerClient(base_url="http://localhost:11235")
+
+results = await client.crawl(
+    urls=["https://httpbin.org/html"],
+    hooks={
+        "on_page_context_created": on_page_context_created,
+        "before_retrieve_html": before_retrieve_html
+    },
+    hooks_timeout=30
+)
+
+if results and results.success:
+    print(f"✅ Hooks executed! HTML length: {len(results.html)}")
+```
+
+**Benefits of Function-Based Hooks:**
+- ✅ Full IDE support (autocomplete, syntax highlighting)
+- ✅ Type checking and linting
+- ✅ Easier to test and debug
+- ✅ Reusable across projects
+- ✅ Automatic conversion in Docker client
+- ✅ No breaking changes - string hooks still work!
+
+## 🤖 Enhanced LLM Integration
+
+Enhanced LLM integration with custom providers, temperature control, and base URL configuration.
+
+### Multi-Provider Support
+
+```python
+from crawl4ai import AsyncWebCrawler, CrawlerRunConfig
+from crawl4ai.extraction_strategy import LLMExtractionStrategy
+
+# Test with different providers
+async def test_llm_providers():
+    # OpenAI with custom temperature
+    openai_strategy = LLMExtractionStrategy(
+        provider="gemini/gemini-2.5-flash-lite",
+        api_token="your-api-token",
+        temperature=0.7,  # New in v0.7.5
+        instruction="Summarize this page in one sentence"
+    )
+
+    async with AsyncWebCrawler() as crawler:
+        result = await crawler.arun(
+            "https://example.com",
+            config=CrawlerRunConfig(extraction_strategy=openai_strategy)
+        )
+
+        if result.success:
+            print("✅ LLM extraction completed")
+            print(result.extracted_content)
+
+# Docker API with enhanced LLM config
+llm_payload = {
+    "url": "https://example.com",
+    "f": "llm",
+    "q": "Summarize this page in one sentence.",
+    "provider": "gemini/gemini-2.5-flash-lite",
+    "temperature": 0.7
+}
+
+response = requests.post("http://localhost:11235/md", json=llm_payload)
+```
+
+**New Features:**
+- Custom `temperature` parameter for creativity control
+- `base_url` for custom API endpoints
+- Multi-provider environment variable support
+- Docker API integration
+
+## 🔒 HTTPS Preservation
+
+**The Problem:** Modern web apps require HTTPS everywhere. When crawlers downgrade internal links from HTTPS to HTTP, authentication breaks and security warnings appear.
+
+**Solution:** HTTPS preservation maintains secure protocols throughout crawling.
+
+```python
+from crawl4ai import AsyncWebCrawler, CrawlerRunConfig, FilterChain, URLPatternFilter, BFSDeepCrawlStrategy
+
+async def test_https_preservation():
+    # Enable HTTPS preservation
+    url_filter = URLPatternFilter(
+        patterns=["^(https:\/\/)?quotes\.toscrape\.com(\/.*)?$"]
+    )
+
+    config = CrawlerRunConfig(
+        exclude_external_links=True,
+        preserve_https_for_internal_links=True,  # New in v0.7.5
+        deep_crawl_strategy=BFSDeepCrawlStrategy(
+            max_depth=2,
+            max_pages=5,
+            filter_chain=FilterChain([url_filter])
+        )
+    )
+
+    async with AsyncWebCrawler() as crawler:
+        async for result in await crawler.arun(
+            url="https://quotes.toscrape.com",
+            config=config
+        ):
+            # All internal links maintain HTTPS
+            internal_links = [link['href'] for link in result.links['internal']]
+            https_links = [link for link in internal_links if link.startswith('https://')]
+
+            print(f"HTTPS links preserved: {len(https_links)}/{len(internal_links)}")
+            for link in https_links[:3]:
+                print(f"  → {link}")
+```
+

+
+## 📊 Real-time Monitoring Dashboard: Complete Visibility
+
+**The Problem:** Running Crawl4AI in Docker was like flying blind. Users had no visibility into what was happening inside the container—memory usage, active requests, browser pools, or errors. Troubleshooting required checking logs, and there was no way to monitor performance or manually intervene when issues occurred.
+
+**My Solution:** I built a complete real-time monitoring system with an interactive dashboard, comprehensive REST API, WebSocket streaming, and manual control actions. Now you have full transparency and control over your crawling infrastructure.
+
+### The Self-Hosting Value Proposition
+
+Before v0.7.7, Docker was just a containerized crawler. After v0.7.7, it's a complete self-hosting platform that gives you:
+
+- **🔒 Data Privacy**: Your data never leaves your infrastructure
+- **💰 Cost Control**: No per-request pricing or rate limits
+- **🎯 Full Customization**: Complete control over configurations and strategies
+- **📊 Complete Transparency**: Real-time visibility into every aspect
+- **⚡ Performance**: Direct access without network overhead
+- **🛡️ Enterprise Security**: Keep workflows behind your firewall
+
+### Interactive Monitoring Dashboard
+
+Access the dashboard at `http://localhost:11235/dashboard` to see:
+
+- **System Health Overview**: CPU, memory, network, and uptime in real-time
+- **Live Request Tracking**: Active and completed requests with full details
+- **Browser Pool Management**: Interactive table with permanent/hot/cold browsers
+- **Janitor Events Log**: Automatic cleanup activities
+- **Error Monitoring**: Full context error logs
+
+The dashboard updates every 2 seconds via WebSocket, giving you live visibility into your crawling operations.
+
+## 🔌 Monitor API: Programmatic Access
+
+**The Problem:** Monitoring dashboards are great for humans, but automation and integration require programmatic access.
+
+**My Solution:** A comprehensive REST API that exposes all monitoring data for integration with your existing infrastructure.
+
+### System Health Endpoint
+
+```python
+import httpx
+import asyncio
+
+async def monitor_system_health():
+    async with httpx.AsyncClient() as client:
+        response = await client.get("http://localhost:11235/monitor/health")
+        health = response.json()
+
+        print(f"Container Metrics:")
+        print(f"  CPU: {health['container']['cpu_percent']:.1f}%")
+        print(f"  Memory: {health['container']['memory_percent']:.1f}%")
+        print(f"  Uptime: {health['container']['uptime_seconds']}s")
+
+        print(f"\nBrowser Pool:")
+        print(f"  Permanent: {health['pool']['permanent']['active']} active")
+        print(f"  Hot Pool: {health['pool']['hot']['count']} browsers")
+        print(f"  Cold Pool: {health['pool']['cold']['count']} browsers")
+
+        print(f"\nStatistics:")
+        print(f"  Total Requests: {health['stats']['total_requests']}")
+        print(f"  Success Rate: {health['stats']['success_rate_percent']:.1f}%")
+        print(f"  Avg Latency: {health['stats']['avg_latency_ms']:.0f}ms")
+
+asyncio.run(monitor_system_health())
+```
+
+### Request Tracking
+
+```python
+async def track_requests():
+    async with httpx.AsyncClient() as client:
+        response = await client.get("http://localhost:11235/monitor/requests")
+        requests_data = response.json()
+
+        print(f"Active Requests: {len(requests_data['active'])}")
+        print(f"Completed Requests: {len(requests_data['completed'])}")
+
+        # See details of recent requests
+        for req in requests_data['completed'][:5]:
+            status_icon = "✅" if req['success'] else "❌"
+            print(f"{status_icon} {req['endpoint']} - {req['latency_ms']:.0f}ms")
+```
+
+### Browser Pool Management
+
+```python
+async def monitor_browser_pool():
+    async with httpx.AsyncClient() as client:
+        response = await client.get("http://localhost:11235/monitor/browsers")
+        browsers = response.json()
+
+        print(f"Pool Summary:")
+        print(f"  Total Browsers: {browsers['summary']['total_count']}")
+        print(f"  Total Memory: {browsers['summary']['total_memory_mb']} MB")
+        print(f"  Reuse Rate: {browsers['summary']['reuse_rate_percent']:.1f}%")
+
+        # List all browsers
+        for browser in browsers['permanent']:
+            print(f"🔥 Permanent: {browser['browser_id'][:8]}... | "
+                  f"Requests: {browser['request_count']} | "
+                  f"Memory: {browser['memory_mb']:.0f} MB")
+```
+
+### Endpoint Performance Statistics
+
+```python
+async def get_endpoint_stats():
+    async with httpx.AsyncClient() as client:
+        response = await client.get("http://localhost:11235/monitor/endpoints/stats")
+        stats = response.json()
+
+        print("Endpoint Analytics:")
+        for endpoint, data in stats.items():
+            print(f"  {endpoint}:")
+            print(f"    Requests: {data['count']}")
+            print(f"    Avg Latency: {data['avg_latency_ms']:.0f}ms")
+            print(f"    Success Rate: {data['success_rate_percent']:.1f}%")
+```
+
+### Complete API Reference
+
+The Monitor API includes these endpoints:
+
+- `GET /monitor/health` - System health with pool statistics
+- `GET /monitor/requests` - Active and completed request tracking
+- `GET /monitor/browsers` - Browser pool details and efficiency
+- `GET /monitor/endpoints/stats` - Per-endpoint performance analytics
+- `GET /monitor/timeline?minutes=5` - Time-series data for charts
+- `GET /monitor/logs/janitor?limit=10` - Cleanup activity logs
+- `GET /monitor/logs/errors?limit=10` - Error logs with context
+- `POST /monitor/actions/cleanup` - Force immediate cleanup
+- `POST /monitor/actions/kill_browser` - Kill specific browser
+- `POST /monitor/actions/restart_browser` - Restart browser
+- `POST /monitor/stats/reset` - Reset accumulated statistics
+
+## ⚡ WebSocket Streaming: Real-time Updates
+
+**The Problem:** Polling the API every few seconds wastes resources and adds latency. Real-time dashboards need instant updates.
+
+**My Solution:** WebSocket streaming with 2-second update intervals for building custom real-time dashboards.
+
+### WebSocket Integration Example
+
+```python
+import websockets
+import json
+import asyncio
+
+async def monitor_realtime():
+    uri = "ws://localhost:11235/monitor/ws"
+
+    async with websockets.connect(uri) as websocket:
+        print("Connected to real-time monitoring stream")
+
+        while True:
+            # Receive update every 2 seconds
+            data = await websocket.recv()
+            update = json.loads(data)
+
+            # Access all monitoring data
+            print(f"\n--- Update at {update['timestamp']} ---")
+            print(f"Memory: {update['health']['container']['memory_percent']:.1f}%")
+            print(f"Active Requests: {len(update['requests']['active'])}")
+            print(f"Total Browsers: {update['browsers']['summary']['total_count']}")
+
+            if update['errors']:
+                print(f"⚠️  Recent Errors: {len(update['errors'])}")
+
+asyncio.run(monitor_realtime())
+```
+
+**Expected Real-World Impact:**
+- **Custom Dashboards**: Build tailored monitoring UIs for your team
+- **Real-time Alerting**: Trigger alerts instantly when metrics exceed thresholds
+- **Integration**: Feed live data into monitoring tools like Grafana
+- **Automation**: React to events in real-time without polling
+
+## 🔥 Smart Browser Pool: 3-Tier Architecture
+
+**The Problem:** Creating a new browser for every request is slow and memory-intensive. Traditional browser pools are static and inefficient.
+
+**My Solution:** A smart 3-tier browser pool that automatically adapts to usage patterns.
+
+### How It Works
+
+```python
+import httpx
+
+async def demonstrate_browser_pool():
+    async with httpx.AsyncClient() as client:
+        # Request 1-3: Default config → Uses permanent browser
+        print("Phase 1: Using permanent browser")
+        for i in range(3):
+            await client.post(
+                "http://localhost:11235/crawl",
+                json={"urls": [f"https://httpbin.org/html?req={i}"]}
+            )
+            print(f"  Request {i+1}: Reused permanent browser")
+
+        # Request 4-6: Custom viewport → Cold pool (first use)
+        print("\nPhase 2: Custom config creates cold pool browser")
+        viewport_config = {"viewport": {"width": 1280, "height": 720}}
+        for i in range(4):
+            await client.post(
+                "http://localhost:11235/crawl",
+                json={
+                    "urls": [f"https://httpbin.org/json?v={i}"],
+                    "browser_config": viewport_config
+                }
+            )
+            if i < 2:
+                print(f"  Request {i+1}: Cold pool browser")
+            else:
+                print(f"  Request {i+1}: Promoted to hot pool! (after 3 uses)")
+
+        # Check pool status
+        response = await client.get("http://localhost:11235/monitor/browsers")
+        browsers = response.json()
+
+        print(f"\nPool Status:")
+        print(f"  Permanent: {len(browsers['permanent'])} (always active)")
+        print(f"  Hot: {len(browsers['hot'])} (frequently used configs)")
+        print(f"  Cold: {len(browsers['cold'])} (on-demand)")
+        print(f"  Reuse Rate: {browsers['summary']['reuse_rate_percent']:.1f}%")
+
+asyncio.run(demonstrate_browser_pool())
+```
+
+**Pool Tiers:**
+
+- **🔥 Permanent Browser**: Always-on, default configuration, instant response
+- **♨️ Hot Pool**: Browsers promoted after 3+ uses, kept warm for quick access
+- **❄️ Cold Pool**: On-demand browsers for variant configs, cleaned up when idle
+
+**Expected Real-World Impact:**
+- **Memory Efficiency**: 10x reduction in memory usage vs creating browsers per request
+- **Performance**: Instant access to frequently-used configurations
+- **Automatic Optimization**: Pool adapts to your usage patterns
+- **Resource Management**: Janitor automatically cleans up idle browsers
+
+## 🧹 Janitor System: Automatic Cleanup
+
+**The Problem:** Long-running crawlers accumulate idle browsers and consume memory over time.
+
+**My Solution:** An automatic janitor system that monitors and cleans up idle resources.
+
+```python
+async def monitor_janitor_activity():
+    async with httpx.AsyncClient() as client:
+        response = await client.get("http://localhost:11235/monitor/logs/janitor?limit=5")
+        logs = response.json()
+
+        print("Recent Cleanup Activities:")
+        for log in logs:
+            print(f"  {log['timestamp']}: {log['message']}")
+
+# Example output:
+# 2025-11-14 10:30:00: Cleaned up 2 cold pool browsers (idle > 5min)
+# 2025-11-14 10:25:00: Browser reuse rate: 85.3%
+# 2025-11-14 10:20:00: Hot pool browser promoted (10 requests)
+```
+
+## 🎮 Control Actions: Manual Management
+
+**The Problem:** Sometimes you need to manually intervene—kill a stuck browser, force cleanup, or restart resources.
+
+**My Solution:** Manual control actions via the API for operational troubleshooting.
+
+### Force Cleanup
+
+```python
+async def force_cleanup():
+    async with httpx.AsyncClient() as client:
+        response = await client.post("http://localhost:11235/monitor/actions/cleanup")
+        result = response.json()
+
+        print(f"Cleanup completed:")
+        print(f"  Browsers cleaned: {result.get('cleaned_count', 0)}")
+        print(f"  Memory freed: {result.get('memory_freed_mb', 0):.1f} MB")
+```
+
+### Kill Specific Browser
+
+```python
+async def kill_stuck_browser(browser_id: str):
+    async with httpx.AsyncClient() as client:
+        response = await client.post(
+            "http://localhost:11235/monitor/actions/kill_browser",
+            json={"browser_id": browser_id}
+        )
+
+        if response.status_code == 200:
+            print(f"✅ Browser {browser_id} killed successfully")
+```
+
+### Reset Statistics
+
+```python
+async def reset_stats():
+    async with httpx.AsyncClient() as client:
+        response = await client.post("http://localhost:11235/monitor/stats/reset")
+        print("📊 Statistics reset for fresh monitoring")
+```
+
+## 📈 Production Integration Patterns
+
+### Prometheus Integration
+
+```python
+# Export metrics for Prometheus scraping
+async def export_prometheus_metrics():
+    async with httpx.AsyncClient() as client:
+        health = await client.get("http://localhost:11235/monitor/health")
+        data = health.json()
+
+        # Export in Prometheus format
+        metrics = f"""
+# HELP crawl4ai_memory_usage_percent Memory usage percentage
+# TYPE crawl4ai_memory_usage_percent gauge
+crawl4ai_memory_usage_percent {data['container']['memory_percent']}
+
+# HELP crawl4ai_request_success_rate Request success rate
+# TYPE crawl4ai_request_success_rate gauge
+crawl4ai_request_success_rate {data['stats']['success_rate_percent']}
+
+# HELP crawl4ai_browser_pool_count Total browsers in pool
+# TYPE crawl4ai_browser_pool_count gauge
+crawl4ai_browser_pool_count {data['pool']['permanent']['active'] + data['pool']['hot']['count'] + data['pool']['cold']['count']}
+"""
+        return metrics
+```
+
+### Alerting Example
+
+```python
+async def check_alerts():
+    async with httpx.AsyncClient() as client:
+        health = await client.get("http://localhost:11235/monitor/health")
+        data = health.json()
+
+        # Memory alert
+        if data['container']['memory_percent'] > 80:
+            print("🚨 ALERT: Memory usage above 80%")
+            # Trigger cleanup
+            await client.post("http://localhost:11235/monitor/actions/cleanup")
+
+        # Success rate alert
+        if data['stats']['success_rate_percent'] < 90:
+            print("🚨 ALERT: Success rate below 90%")
+            # Check error logs
+            errors = await client.get("http://localhost:11235/monitor/logs/errors")
+            print(f"Recent errors: {len(errors.json())}")
+
+        # Latency alert
+        if data['stats']['avg_latency_ms'] > 5000:
+            print("🚨 ALERT: Average latency above 5s")
+```
+
+### Key Metrics to Track
+
+```python
+CRITICAL_METRICS = {
+    "memory_usage": {
+        "current": "container.memory_percent",
+        "target": "<80%",
+        "alert_threshold": ">80%",
+        "action": "Force cleanup or scale"
+    },
+    "success_rate": {
+        "current": "stats.success_rate_percent",
+        "target": ">95%",
+        "alert_threshold": "<90%",
+        "action": "Check error logs"
+    },
+    "avg_latency": {
+        "current": "stats.avg_latency_ms",
+        "target": "<2000ms",
+        "alert_threshold": ">5000ms",
+        "action": "Investigate slow requests"
+    },
+    "browser_reuse_rate": {
+        "current": "browsers.summary.reuse_rate_percent",
+        "target": ">80%",
+        "alert_threshold": "<60%",

+        "target": "<5/hour",
+        "alert_threshold": ">10/hour",
+        "action": "Review error patterns"
+    }
+}
+```
+
+## 🐛 Critical Bug Fixes
+
+This release includes significant bug fixes that improve stability and performance:
+
+### Async LLM Extraction (#1590)
+
+**The Problem:** LLM extraction was blocking async execution, causing URLs to be processed sequentially instead of in parallel (issue #1055).
+
+**The Fix:** Resolved the blocking issue to enable true parallel processing for LLM extraction.
+
+```python
+# Before v0.7.7: Sequential processing
+# After v0.7.7: True parallel processing
+
+async with AsyncWebCrawler() as crawler:
+    urls = ["url1", "url2", "url3", "url4"]
+
+    # Now processes truly in parallel with LLM extraction
+    results = await crawler.arun_many(
+        urls,
+        config=CrawlerRunConfig(
+            extraction_strategy=LLMExtractionStrategy(...)
+        )
+    )
+    # 4x faster for parallel LLM extraction!
+```
+
+**Expected Impact:** Major performance improvement for batch LLM extraction workflows.
+
+### DFS Deep Crawling (#1607)
+
+**The Problem:** DFS (Depth-First Search) deep crawl strategy had implementation issues.
+
+**The Fix:** Enhanced DFSDeepCrawlStrategy with proper seen URL tracking and improved documentation.
+
+### Browser & Crawler Config Documentation (#1609)
+
+**The Problem:** Documentation didn't match the actual `async_configs.py` implementation.
+
+**The Fix:** Updated all configuration documentation to accurately reflect the current implementation.
+
+### Sitemap Seeder (#1598)
+
+**The Problem:** Sitemap parsing and URL normalization issues in AsyncUrlSeeder (issue #1559).
+
+**The Fix:** Added comprehensive tests and fixes for sitemap namespace parsing and URL normalization.
+
+### Remove Overlay Elements (#1529)
+
+**The Problem:** The `remove_overlay_elements` functionality wasn't working (issue #1396).
+
+**The Fix:** Fixed by properly calling the injected JavaScript function.
+
+### Viewport Configuration (#1495)
+
+**The Problem:** Viewport configuration wasn't working in managed browsers (issue #1490).
+
+**The Fix:** Added proper viewport size configuration support for browser launch.
+
+### Managed Browser CDP Timing (#1528)
+
+**The Problem:** CDP (Chrome DevTools Protocol) endpoint verification had timing issues causing connection failures (issue #1445).
+
+**The Fix:** Added exponential backoff for CDP endpoint verification to handle timing variations.
