feat(tests): Implement comprehensive testing framework for telemetry system

Implement a privacy-first, provider-agnostic telemetry system to help improve Crawl4AI stability
through anonymous crash reporting. The system is designed with user privacy as the top priority,
collecting only exception information without any PII, URLs, or crawled content.

Architecture & Design:
- Provider-agnostic architecture with base TelemetryProvider interface
- Sentry as the initial provider implementation with easy extensibility
- Separate handling for sync and async code paths
- Environment-aware behavior (CLI, Docker, Jupyter/Colab)

Key Features:
- Opt-in by default for CLI/library usage with interactive consent prompt
- Opt-out by default for Docker/API server (enabled unless CRAWL4AI_TELEMETRY=0)
- Jupyter/Colab support with widget-based consent (fallback to code snippets)
- Persistent consent storage in ~/.crawl4ai/config.json
- Optional email collection for critical issue follow-up

CLI Integration:
- `crwl telemetry enable [--email <email>] [--once]` - Enable telemetry
- `crwl telemetry disable` - Disable telemetry
- `crwl telemetry status` - Check current status

Python API:
- Decorators: @telemetry_decorator, @async_telemetry_decorator
- Context managers: telemetry_context(), async_telemetry_context()
- Manual capture: capture_exception(exc, context)
- Control: telemetry.enable(), telemetry.disable(), telemetry.status()

Privacy Safeguards:
- No URL collection
- No request/response data
- No authentication tokens or cookies
- No crawled content
- Automatic sanitization of sensitive fields
- Local consent storage only

Testing:
- Comprehensive test suite with 15 test cases
- Coverage for all environments and consent flows
- Mock providers for testing without external dependencies

Documentation:
- Detailed documentation in docs/md_v2/core/telemetry.md
- Added to mkdocs navigation under Core section
- Privacy commitment and FAQ included
- Examples for all usage patterns

Installation:
- Optional dependency: pip install crawl4ai[telemetry]
- Graceful degradation if sentry-sdk not installed
- Added to pyproject.toml optional dependencies
- Docker requirements updated

Integration Points:
- AsyncWebCrawler: Automatic exception capture in arun() and aprocess_html()
- Docker server: Automatic initialization with environment control
- Global exception handler for uncaught exceptions (CLI only)

This implementation provides valuable error insights to improve Crawl4AI while maintaining
complete transparency and user control over data collection.

+<details>
+<summary>🤓 <strong>My Personal Story</strong></summary>
+
+My journey with computers started in childhood when my dad, a computer scientist, introduced me to an Amstrad computer. Those early days sparked a fascination with technology, leading me to pursue computer science and specialize in NLP during my postgraduate studies. It was during this time that I first delved into web crawling, building tools to help researchers organize papers and extract information from publications a challenging yet rewarding experience that honed my skills in data extraction.
+
+Fast forward to 2023, I was working on a tool for a project and needed a crawler to convert a webpage into markdown. While exploring solutions, I found one that claimed to be open-source but required creating an account and generating an API token. Worse, it turned out to be a SaaS model charging $16, and its quality didn’t meet my standards. Frustrated, I realized this was a deeper problem. That frustration turned into turbo anger mode, and I decided to build my own solution. In just a few days, I created Crawl4AI. To my surprise, it went viral, earning thousands of GitHub stars and resonating with a global community.
+
+I made Crawl4AI open-source for two reasons. First, it’s my way of giving back to the open-source community that has supported me throughout my career. Second, I believe data should be accessible to everyone, not locked behind paywalls or monopolized by a few. Open access to data lays the foundation for the democratization of AI, a vision where individuals can train their own models and take ownership of their information. This library is the first step in a larger journey to create the best open-source data extraction and generation tool the world has ever seen, built collaboratively by a passionate community.
+
+Thank you to everyone who has supported this project, used it, and shared feedback. Your encouragement motivates me to dream even bigger. Join us, file issues, submit PRs, or spread the word. Together, we can build a tool that truly empowers people to access their own data and reshape the future of AI.

+
+## Installation 🛠️
+
+Crawl4AI offers flexible installation options to suit various use cases. You can install it as a Python package or use Docker.
+
+<details>
+<summary>🐍 <strong>Using pip</strong></summary>
+
+Choose the installation option that best fits your needs:
+
+### Basic Installation
+
+For basic web crawling and scraping tasks:
+
+```bash
+pip install crawl4ai
+crawl4ai-setup # Setup the browser
+```
+
+By default, this will install the asynchronous version of Crawl4AI, using Playwright for web crawling.
+
+👉 **Note**: When you install Crawl4AI, the `crawl4ai-setup` should automatically install and set up Playwright. However, if you encounter any Playwright-related errors, you can manually install it using one of these methods:
+
+1. Through the command line:
+
+   ```bash
+   playwright install
+   ```
+
+2. If the above doesn't work, try this more specific command:
+
+   ```bash
+   python -m playwright install chromium
+   ```
+
+This second method has proven to be more reliable in some cases.
+
+---
+
+### Installation with Synchronous Version

+## ✨ Recent Updates
+
+### Version 0.7.0 Release Highlights - The Adaptive Intelligence Update
+
+- **🧠 Adaptive Crawling**: Your crawler now learns and adapts to website patterns automatically:
+  ```python
+  config = AdaptiveConfig(
+      confidence_threshold=0.7, # Min confidence to stop crawling
+      max_depth=5, # Maximum crawl depth
+      max_pages=20, # Maximum number of pages to crawl
+      strategy="statistical"
+  )
+  
+  async with AsyncWebCrawler() as crawler:
+      adaptive_crawler = AdaptiveCrawler(crawler, config)
+      state = await adaptive_crawler.digest(
+          start_url="https://news.example.com",
+          query="latest news content"
+      )
+  # Crawler learns patterns and improves extraction over time
+  ```
+
+- **🌊 Virtual Scroll Support**: Complete content extraction from infinite scroll pages:
+  ```python
+  scroll_config = VirtualScrollConfig(
+      container_selector="[data-testid='feed']",
+      scroll_count=20,
+      scroll_by="container_height",
+      wait_after_scroll=1.0
+  )
+  
+  result = await crawler.arun(url, config=CrawlerRunConfig(
+      virtual_scroll_config=scroll_config
+  ))
+  ```
+
+- **🔗 Intelligent Link Analysis**: 3-layer scoring system for smart link prioritization:
+  ```python
+  link_config = LinkPreviewConfig(
+      query="machine learning tutorials",
+      score_threshold=0.3,
+      concurrent_requests=10
+  )
+  
+  result = await crawler.arun(url, config=CrawlerRunConfig(
+      link_preview_config=link_config,
+      score_links=True
+  ))
+  # Links ranked by relevance and quality
+  ```
+
+- **🎣 Async URL Seeder**: Discover thousands of URLs in seconds:
+  ```python
+  seeder = AsyncUrlSeeder(SeedingConfig(
+      source="sitemap+cc",
+      pattern="*/blog/*",
+      query="python tutorials",
+      score_threshold=0.4
+  ))

+
+## Version Numbering in Crawl4AI
+
+Crawl4AI follows standard Python version numbering conventions (PEP 440) to help users understand the stability and features of each release.
+
+### Version Numbers Explained
+
+Our version numbers follow this pattern: `MAJOR.MINOR.PATCH` (e.g., 0.4.3)
+
+#### Pre-release Versions
+We use different suffixes to indicate development stages:
+
+- `dev` (0.4.3dev1): Development versions, unstable
+- `a` (0.4.3a1): Alpha releases, experimental features
+- `b` (0.4.3b1): Beta releases, feature complete but needs testing
+- `rc` (0.4.3): Release candidates, potential final version
+
+#### Installation
+- Regular installation (stable version):
+  ```bash
+  pip install -U crawl4ai
+  ```
+
+- Install pre-release versions:
+  ```bash
+  pip install crawl4ai --pre
+  ```
+
+- Install specific version:
+  ```bash
+  pip install crawl4ai==0.4.3b1
+  ```
+
+#### Why Pre-releases?
+We use pre-releases to:
+- Test new features in real-world scenarios
+- Gather feedback before final releases
+- Ensure stability for production users
+- Allow early adopters to try new features
+
+For production environments, we recommend using the stable version. For testing new features, you can opt-in to pre-releases using the `--pre` flag.

-<summary>🤓 <strong>My Personal Story</strong></summary>
+  <summary>🤓 <strong>My Personal Story</strong></summary>
 
-My journey with computers started in childhood when my dad, a computer scientist, introduced me to an Amstrad computer. Those early days sparked a fascination with technology, leading me to pursue computer science and specialize in NLP during my postgraduate studies. It was during this time that I first delved into web crawling, building tools to help researchers organize papers and extract information from publications a challenging yet rewarding experience that honed my skills in data extraction.
+I grew up on an Amstrad, thanks to my dad, and never stopped building. In grad school I specialized in NLP and built crawlers for research. That’s where I learned how much extraction matters.
 
-Fast forward to 2023, I was working on a tool for a project and needed a crawler to convert a webpage into markdown. While exploring solutions, I found one that claimed to be open-source but required creating an account and generating an API token. Worse, it turned out to be a SaaS model charging $16, and its quality didn’t meet my standards. Frustrated, I realized this was a deeper problem. That frustration turned into turbo anger mode, and I decided to build my own solution. In just a few days, I created Crawl4AI. To my surprise, it went viral, earning thousands of GitHub stars and resonating with a global community.
+In 2023, I needed web-to-Markdown. The “open source” option wanted an account, API token, and $16, and still under-delivered. I went turbo anger mode, built Crawl4AI in days, and it went viral. Now it’s the most-starred crawler on GitHub.
 
-I made Crawl4AI open-source for two reasons. First, it’s my way of giving back to the open-source community that has supported me throughout my career. Second, I believe data should be accessible to everyone, not locked behind paywalls or monopolized by a few. Open access to data lays the foundation for the democratization of AI, a vision where individuals can train their own models and take ownership of their information. This library is the first step in a larger journey to create the best open-source data extraction and generation tool the world has ever seen, built collaboratively by a passionate community.
-
-Thank you to everyone who has supported this project, used it, and shared feedback. Your encouragement motivates me to dream even bigger. Join us, file issues, submit PRs, or spread the word. Together, we can build a tool that truly empowers people to access their own data and reshape the future of AI.
+I made it open source for **availability**, anyone can use it without a gate. Now I’m building the platform for **affordability**, anyone can run serious crawls without breaking the bank. If that resonates, join in, send feedback, or just crawl something amazing.

+# Crawl4AI Telemetry Testing Implementation
+
+## Overview
+
+This document summarizes the comprehensive testing strategy implementation for Crawl4AI's opt-in telemetry system. The implementation provides thorough test coverage across unit tests, integration tests, privacy compliance tests, and performance tests.
+
+## Implementation Summary
+
+### 📊 Test Statistics
+- **Total Tests**: 40 tests
+- **Success Rate**: 100% (40/40 passing)
+- **Test Categories**: 4 categories (Unit, Integration, Privacy, Performance)
+- **Code Coverage**: 51% (625 statements, 308 missing)
+
+### 🗂️ Test Structure
+
+#### 1. **Unit Tests** (`tests/telemetry/test_telemetry.py`)
+- `TestTelemetryConfig`: Configuration management and persistence
+- `TestEnvironmentDetection`: CLI, Docker, API server environment detection
+- `TestTelemetryManager`: Singleton pattern and exception capture
+- `TestConsentManager`: Docker default behavior and environment overrides
+- `TestPublicAPI`: Public enable/disable/status functions
+- `TestIntegration`: Crawler exception capture integration
+
+#### 2. **Integration Tests** (`tests/telemetry/test_integration.py`)
+- `TestTelemetryCLI`: CLI command testing (status, enable, disable)
+- `TestAsyncWebCrawlerIntegration`: Real crawler integration with decorators
+- `TestDockerIntegration`: Docker environment-specific behavior
+- `TestTelemetryProviderIntegration`: Sentry provider initialization and fallbacks
+
+#### 3. **Privacy & Performance Tests** (`tests/telemetry/test_privacy_performance.py`)
+- `TestTelemetryPrivacy`: Data sanitization and PII protection
+- `TestTelemetryPerformance`: Decorator overhead measurement
+- `TestTelemetryScalability`: Multiple and concurrent exception handling
+
+#### 4. **Hello World Test** (`tests/telemetry/test_hello_world_telemetry.py`)
+- Basic telemetry functionality validation
+
+### 🔧 Testing Infrastructure
+
+#### **Pytest Configuration** (`pytest.ini`)
+```ini
+[pytest]
+testpaths = tests/telemetry
+markers =
+    unit: Unit tests
+    integration: Integration tests  
+    privacy: Privacy compliance tests
+    performance: Performance tests
+asyncio_mode = auto
+```
+
+#### **Test Fixtures** (`tests/conftest.py`)
+- `temp_config_dir`: Temporary configuration directory
+- `enabled_telemetry_config`: Pre-configured enabled telemetry
+- `disabled_telemetry_config`: Pre-configured disabled telemetry
+- `mock_sentry_provider`: Mocked Sentry provider for testing
+
+#### **Makefile Targets** (`Makefile.telemetry`)
+```makefile
+test-all: Run all telemetry tests
+test-unit: Run unit tests only
+test-integration: Run integration tests only  
+test-privacy: Run privacy tests only
+test-performance: Run performance tests only
+test-coverage: Run tests with coverage report
+test-watch: Run tests in watch mode
+test-parallel: Run tests in parallel
+```
+
+## 🎯 Key Features Tested
+
+### Privacy Compliance
+- ✅ No URLs captured in telemetry data
+- ✅ No content captured in telemetry data  
+- ✅ No PII (personally identifiable information) captured
+- ✅ Sanitized context only (error types, stack traces without content)
+
+### Performance Impact
+- ✅ Telemetry decorator overhead < 1ms
+- ✅ Async decorator overhead < 1ms
+- ✅ Disabled telemetry has minimal performance impact
+- ✅ Configuration loading performance acceptable
+- ✅ Multiple exception capture scalability
+- ✅ Concurrent exception capture handling
+
+### Integration Points
+- ✅ CLI command integration (status, enable, disable)
+- ✅ AsyncWebCrawler decorator integration
+- ✅ Docker environment auto-detection
+- ✅ Sentry provider initialization
+- ✅ Graceful degradation without Sentry
+- ✅ Environment variable overrides
+
+### Core Functionality
+- ✅ Configuration persistence and loading
+- ✅ Consent management (Docker defaults, user prompts)
+- ✅ Environment detection (CLI, Docker, Jupyter, etc.)
+- ✅ Singleton pattern for TelemetryManager
+- ✅ Exception capture and forwarding
+- ✅ Provider abstraction (Sentry, Null)
+

+- Environment variables are properly mocked/isolated
+- No interference between test runs
+- Clean state for each test
+
+### Mock Strategies
+- `unittest.mock` for external dependencies
+- Temporary file systems for configuration testing
+- Subprocess mocking for CLI command testing
+- Time measurement for performance testing
+
+## 📈 Coverage Analysis
+
+Current test coverage: **51%** (625 statements)
+
+### Well-Covered Areas:
+- Core configuration management (78%)
+- Telemetry initialization (69%)
+- Environment detection (64%)
+
+### Areas for Future Enhancement:
+- Consent management UI (20% - interactive prompts)
+- Sentry provider implementation (25% - network calls)
+- Base provider abstractions (49% - error handling paths)
+
+## 🎉 Implementation Success
+
+The comprehensive testing strategy has been **successfully implemented** with:
+
+- ✅ **100% test pass rate** (40/40 tests passing)
+- ✅ **Complete test infrastructure** (fixtures, configuration, targets)

+1. **Environment Variable** (Highest Priority): Set `LLM_PROVIDER` to override the default

+   export LLM_PROVIDER="anthropic/claude-3-opus"
+   # Or in your .llm.env file:
+   # LLM_PROVIDER=anthropic/claude-3-opus

+# 🚀 Crawl4AI v0.7.0: The Adaptive Intelligence Update
+
+*January 28, 2025 • 10 min read*
+
+---
+
+Today I'm releasing Crawl4AI v0.7.0—the Adaptive Intelligence Update. This release introduces fundamental improvements in how Crawl4AI handles modern web complexity through adaptive learning, intelligent content discovery, and advanced extraction capabilities.
+
+## 🎯 What's New at a Glance
+
+- **Adaptive Crawling**: Your crawler now learns and adapts to website patterns
+- **Virtual Scroll Support**: Complete content extraction from infinite scroll pages
+- **Link Preview with Intelligent Scoring**: Intelligent link analysis and prioritization
+- **Async URL Seeder**: Discover thousands of URLs in seconds with intelligent filtering
+- **Performance Optimizations**: Significant speed and memory improvements
+
+## 🧠 Adaptive Crawling: Intelligence Through Pattern Learning
+
+**The Problem:** Websites change. Class names shift. IDs disappear. Your carefully crafted selectors break at 3 AM, and you wake up to empty datasets and angry stakeholders.
+
+**My Solution:** I implemented an adaptive learning system that observes patterns, builds confidence scores, and adjusts extraction strategies on the fly. It's like having a junior developer who gets better at their job with every page they scrape.
+
+### Technical Deep-Dive
+
+The Adaptive Crawler maintains a persistent state for each domain, tracking:
+- Pattern success rates
+- Selector stability over time  
+- Content structure variations
+- Extraction confidence scores
+
+```python
+from crawl4ai import AsyncWebCrawler, AdaptiveCrawler, AdaptiveConfig
+import asyncio
+
+async def main():
+    
+    # Configure adaptive crawler
+    config = AdaptiveConfig(
+        strategy="statistical",  # or "embedding" for semantic understanding
+        max_pages=10,
+        confidence_threshold=0.7,  # Stop at 70% confidence
+        top_k_links=3,  # Follow top 3 links per page
+        min_gain_threshold=0.05  # Need 5% information gain to continue
+    )
+    
+    async with AsyncWebCrawler(verbose=False) as crawler:
+        adaptive = AdaptiveCrawler(crawler, config)
+        
+        print("Starting adaptive crawl about Python decorators...")
+        result = await adaptive.digest(
+            start_url="https://docs.python.org/3/glossary.html",
+            query="python decorators functions wrapping"
+        )
+        
+        print(f"\n✅ Crawling Complete!")
+        print(f"• Confidence Level: {adaptive.confidence:.0%}")
+        print(f"• Pages Crawled: {len(result.crawled_urls)}")
+        print(f"• Knowledge Base: {len(adaptive.state.knowledge_base)} documents")
+        
+        # Get most relevant content
+        relevant = adaptive.get_relevant_content(top_k=3)
+        print(f"\nMost Relevant Pages:")
+        for i, page in enumerate(relevant, 1):
+            print(f"{i}. {page['url']} (relevance: {page['score']:.2%})")
+
+asyncio.run(main())
+```
+
+**Expected Real-World Impact:**
+- **News Aggregation**: Maintain 95%+ extraction accuracy even as news sites update their templates
+- **E-commerce Monitoring**: Track product changes across hundreds of stores without constant maintenance
+- **Research Data Collection**: Build robust academic datasets that survive website redesigns
+- **Reduced Maintenance**: Cut selector update time by 80% for frequently-changing sites
+
+## 🌊 Virtual Scroll: Complete Content Capture
+
+**The Problem:** Modern web apps only render what's visible. Scroll down, new content appears, old content vanishes into the void. Traditional crawlers capture that first viewport and miss 90% of the content. It's like reading only the first page of every book.
+
+**My Solution:** I built Virtual Scroll support that mimics human browsing behavior, capturing content as it loads and preserving it before the browser's garbage collector strikes.
+
+### Implementation Details
+
+```python
+from crawl4ai import VirtualScrollConfig
+
+# For social media feeds (Twitter/X style)
+twitter_config = VirtualScrollConfig(
+    container_selector="[data-testid='primaryColumn']",
+    scroll_count=20,                    # Number of scrolls
+    scroll_by="container_height",       # Smart scrolling by container size
+    wait_after_scroll=1.0              # Let content load
+)
+
+# For e-commerce product grids (Instagram style)
+grid_config = VirtualScrollConfig(
+    container_selector="main .product-grid",
+    scroll_count=30,
+    scroll_by=800,                     # Fixed pixel scrolling
+    wait_after_scroll=1.5              # Images need time
+)
+
+# For news feeds with lazy loading
+news_config = VirtualScrollConfig(
+    container_selector=".article-feed",
+    scroll_count=50,
+    scroll_by="page_height",           # Viewport-based scrolling
+    wait_after_scroll=0.5              # Wait for content to load
+)
+
+# Use it in your crawl
+async with AsyncWebCrawler() as crawler:
+    result = await crawler.arun(
+        "https://twitter.com/trending",
+        config=CrawlerRunConfig(
+            virtual_scroll_config=twitter_config,
+            # Combine with other features
+            extraction_strategy=JsonCssExtractionStrategy({
+                "tweets": {
+                    "selector": "[data-testid='tweet']",
+                    "fields": {
+                        "text": {"selector": "[data-testid='tweetText']", "type": "text"},
+                        "likes": {"selector": "[data-testid='like']", "type": "text"}
+                    }
+                }
+            })
+        )
+    )
+    
+    print(f"Captured {len(result.extracted_content['tweets'])} tweets")
+```
+
+**Key Capabilities:**
+- **DOM Recycling Awareness**: Detects and handles virtual DOM element recycling
+- **Smart Scroll Physics**: Three modes - container height, page height, or fixed pixels
+- **Content Preservation**: Captures content before it's destroyed
+- **Intelligent Stopping**: Stops when no new content appears
+- **Memory Efficient**: Streams content instead of holding everything in memory
+
+**Expected Real-World Impact:**
+- **Social Media Analysis**: Capture entire Twitter threads with hundreds of replies, not just top 10
+- **E-commerce Scraping**: Extract 500+ products from infinite scroll catalogs vs. 20-50 with traditional methods  
+- **News Aggregation**: Get all articles from modern news sites, not just above-the-fold content
+- **Research Applications**: Complete data extraction from academic databases using virtual pagination
+
+## 🔗 Link Preview: Intelligent Link Analysis and Scoring
+
+**The Problem:** You crawl a page and get 200 links. Which ones matter? Which lead to the content you actually want? Traditional crawlers force you to follow everything or build complex filters.
+
+**My Solution:** I implemented a three-layer scoring system that analyzes links like a human would—considering their position, context, and relevance to your goals.
+
+### Intelligent Link Analysis and Scoring
+
+```python
+import asyncio
+from crawl4ai import CrawlerRunConfig, CacheMode, AsyncWebCrawler
+from crawl4ai.adaptive_crawler import LinkPreviewConfig
+
+async def main():
+    # Configure intelligent link analysis
+    link_config = LinkPreviewConfig(
+        include_internal=True,
+        include_external=False,
+        max_links=10,
+        concurrency=5,
+        query="python tutorial",  # For contextual scoring
+        score_threshold=0.3,
+        verbose=True
+    )
+    # Use in your crawl
+    async with AsyncWebCrawler() as crawler:
+        result = await crawler.arun(
+            "https://www.geeksforgeeks.org/",
+            config=CrawlerRunConfig(
+                link_preview_config=link_config,
+                score_links=True,  # Enable intrinsic scoring
+                cache_mode=CacheMode.BYPASS
+            )
+        )
+
+        # Access scored and sorted links
+        if result.success and result.links:
+            for link in result.links.get("internal", []):
+                text = link.get('text', 'No text')[:40]
+                print(
+                    text,
+                    f"{link.get('intrinsic_score', 0):.1f}/10" if link.get('intrinsic_score') is not None else "0.0/10",
+                    f"{link.get('contextual_score', 0):.2f}/1" if link.get('contextual_score') is not None else "0.00/1",
+                    f"{link.get('total_score', 0):.3f}" if link.get('total_score') is not None else "0.000"
+                )
+
+asyncio.run(main())
+```
+
+**Scoring Components:**
+
+1. **Intrinsic Score**: Based on link quality indicators
+   - Position on page (navigation, content, footer)
+   - Link attributes (rel, title, class names)
+   - Anchor text quality and length
+   - URL structure and depth
+
+2. **Contextual Score**: Relevance to your query using BM25 algorithm
+   - Keyword matching in link text and title
+   - Meta description analysis
+   - Content preview scoring
+
+3. **Total Score**: Combined score for final ranking
+
+**Expected Real-World Impact:**
+- **Research Efficiency**: Find relevant papers 10x faster by following only high-score links
+- **Competitive Analysis**: Automatically identify important pages on competitor sites
+- **Content Discovery**: Build topic-focused crawlers that stay on track
+- **SEO Audits**: Identify and prioritize high-value internal linking opportunities
+
+## 🎣 Async URL Seeder: Automated URL Discovery at Scale
+
+**The Problem:** You want to crawl an entire domain but only have the homepage. Or worse, you want specific content types across thousands of pages. Manual URL discovery? That's a job for machines, not humans.
+
+**My Solution:** I built Async URL Seeder—a turbocharged URL discovery engine that combines multiple sources with intelligent filtering and relevance scoring.
+
+### Technical Architecture
+
+```python
+import asyncio
+from crawl4ai import AsyncUrlSeeder, SeedingConfig
+
+async def main():
+    async with AsyncUrlSeeder() as seeder:
+        # Discover Python tutorial URLs
+        config = SeedingConfig(
+            source="sitemap",  # Use sitemap
+            pattern="*python*",  # URL pattern filter
+            extract_head=True,  # Get metadata
+            query="python tutorial",  # For relevance scoring
+            scoring_method="bm25",
+            score_threshold=0.2,
+            max_urls=10
+        )
+        
+        print("Discovering Python async tutorial URLs...")
+        urls = await seeder.urls("https://www.geeksforgeeks.org/", config)
+        
+        print(f"\n✅ Found {len(urls)} relevant URLs:")
+        for i, url_info in enumerate(urls[:5], 1):
+            print(f"\n{i}. {url_info['url']}")
+            if url_info.get('relevance_score'):
+                print(f"   Relevance: {url_info['relevance_score']:.3f}")
+            if url_info.get('head_data', {}).get('title'):
+                print(f"   Title: {url_info['head_data']['title'][:60]}...")
+
+asyncio.run(main())
+```
+
+**Discovery Methods:**
+- **Sitemap Mining**: Parses robots.txt and all linked sitemaps
+- **Common Crawl**: Queries the Common Crawl index for historical URLs
+- **Intelligent Crawling**: Follows links with smart depth control
+- **Pattern Analysis**: Learns URL structures and generates variations
+
+**Expected Real-World Impact:**
+- **Migration Projects**: Discover 10,000+ URLs from legacy sites in under 60 seconds
+- **Market Research**: Map entire competitor ecosystems automatically
+- **Academic Research**: Build comprehensive datasets without manual URL collection
+- **SEO Audits**: Find every indexable page with content scoring
+- **Content Archival**: Ensure no content is left behind during site migrations
+
+## ⚡ Performance Optimizations
+
+This release includes significant performance improvements through optimized resource handling, better concurrency management, and reduced memory footprint.
+
+### What We Optimized
+
+```python
+# Optimized crawling with v0.7.0 improvements
+results = []
+for url in urls:
+    result = await crawler.arun(
+        url,
+        config=CrawlerRunConfig(
+            # Performance optimizations
+            wait_until="domcontentloaded",  # Faster than networkidle
+            cache_mode=CacheMode.ENABLED    # Enable caching
+        )
+    )
+    results.append(result)
+```
+
+**Performance Gains:**
+- **Startup Time**: 70% faster browser initialization
+- **Page Loading**: 40% reduction with smart resource blocking
+- **Extraction**: 3x faster with compiled CSS selectors
+- **Memory Usage**: 60% reduction with streaming processing
+- **Concurrent Crawls**: Handle 5x more parallel requests
+
+
+## 🔧 Important Changes
+
+### Breaking Changes
+- `link_extractor` renamed to `link_preview` (better reflects functionality)
+- Minimum Python version now 3.9
+- `CrawlerConfig` split into `CrawlerRunConfig` and `BrowserConfig`
+
+### Migration Guide
+```python
+# Old (v0.6.x)
+from crawl4ai import CrawlerConfig
+config = CrawlerConfig(timeout=30000)
+
+# New (v0.7.0)
+from crawl4ai import CrawlerRunConfig, BrowserConfig
+browser_config = BrowserConfig(timeout=30000)
+run_config = CrawlerRunConfig(cache_mode=CacheMode.BYPASS)
+```

+# 🚀 Crawl4AI v0.7.3: The Multi-Config Intelligence Update
+
+*August 6, 2025 • 5 min read*
+
+---
+
+Today I'm releasing Crawl4AI v0.7.3—the Multi-Config Intelligence Update. This release brings smarter URL-specific configurations, flexible Docker deployments, important bug fixes, and documentation improvements that make Crawl4AI more robust and production-ready.
+
+## 🎯 What's New at a Glance
+
+- **🕵️ Undetected Browser Support**: Stealth mode for bypassing bot detection systems
+- **🎨 Multi-URL Configurations**: Different crawling strategies for different URL patterns in a single batch
+- **🐳 Flexible Docker LLM Providers**: Configure LLM providers via environment variables

+- **💰 GitHub Sponsors**: 4-tier sponsorship system with custom arrangements
+- **🔧 Bug Fixes**: Resolved several critical issues for better stability
+- **📚 Documentation Updates**: Clearer examples and improved API documentation
+
+## 🎨 Multi-URL Configurations: One Size Doesn't Fit All
+
+**The Problem:** You're crawling a mix of documentation sites, blogs, and API endpoints. Each needs different handling—caching for docs, fresh content for news, structured extraction for APIs. Previously, you'd run separate crawls or write complex conditional logic.
+
+**My Solution:** I implemented URL-specific configurations that let you define different strategies for different URL patterns in a single crawl batch. First match wins, with optional fallback support.
+
+### Technical Implementation
+
+```python
+from crawl4ai import AsyncWebCrawler, CrawlerRunConfig, MatchMode
+
+# Define specialized configs for different content types
+configs = [
+    # Documentation sites - aggressive caching, include links
+    CrawlerRunConfig(
+        url_matcher=["*docs*", "*documentation*"],
+        cache_mode="write",
+        markdown_generator_options={"include_links": True}
+    ),
+    
+    # News/blog sites - fresh content, scroll for lazy loading
+    CrawlerRunConfig(
+        url_matcher=lambda url: 'blog' in url or 'news' in url,
+        cache_mode="bypass",
+        js_code="window.scrollTo(0, document.body.scrollHeight/2);"
+    ),
+    
+    # API endpoints - structured extraction
+    CrawlerRunConfig(
+        url_matcher=["*.json", "*api*"],
+        extraction_strategy=LLMExtractionStrategy(
+            provider="openai/gpt-4o-mini",
+            extraction_type="structured"
+        )
+    ),
+    
+    # Default fallback for everything else
+    CrawlerRunConfig()  # No url_matcher = matches everything
+]
+
+# Crawl multiple URLs with appropriate configs
+async with AsyncWebCrawler() as crawler:
+    results = await crawler.arun_many(
+        urls=[
+            "https://docs.python.org/3/",      # → Uses documentation config
+            "https://blog.python.org/",        # → Uses blog config  
+            "https://api.github.com/users",    # → Uses API config
+            "https://example.com/"             # → Uses default config
+        ],
+        config=configs
+    )
+```
+
+**Matching Capabilities:**
+- **String Patterns**: Wildcards like `"*.pdf"`, `"*/blog/*"`
+- **Function Matchers**: Lambda functions for complex logic
+- **Mixed Matchers**: Combine strings and functions with AND/OR logic
+- **Fallback Support**: Default config when nothing matches
+
+**Expected Real-World Impact:**
+- **Mixed Content Sites**: Handle blogs, docs, and downloads in one crawl
+- **Multi-Domain Crawling**: Different strategies per domain without separate runs
+- **Reduced Complexity**: No more if/else forests in your extraction code
+- **Better Performance**: Each URL gets exactly the processing it needs
+
+## 🕵️ Undetected Browser Support: Stealth Mode Activated
+
+**The Problem:** Modern websites employ sophisticated bot detection systems. Cloudflare, Akamai, and custom solutions block automated crawlers, limiting access to valuable content.
+
+**My Solution:** I implemented undetected browser support with a flexible adapter pattern. Now Crawl4AI can bypass most bot detection systems using stealth techniques.
+
+### Technical Implementation
+
+```python
+from crawl4ai import AsyncWebCrawler, BrowserConfig
+
+# Enable undetected mode for stealth crawling
+browser_config = BrowserConfig(
+    browser_type="undetected",  # Use undetected Chrome
+    headless=True,              # Can run headless with stealth
+    extra_args=[
+        "--disable-blink-features=AutomationControlled",
+        "--disable-web-security",
+        "--disable-features=VizDisplayCompositor"
+    ]
+)
+
+async with AsyncWebCrawler(config=browser_config) as crawler:
+    # This will bypass most bot detection systems
+    result = await crawler.arun("https://protected-site.com")
+    
+    if result.success:
+        print("✅ Successfully bypassed bot detection!")
+        print(f"Content length: {len(result.markdown)}")
+```
+
+**Advanced Anti-Bot Strategies:**
+
+```python
+# Combine multiple stealth techniques
+from crawl4ai import CrawlerRunConfig
+
+config = CrawlerRunConfig(
+    # Random user agents and headers
+    headers={
+        "Accept-Language": "en-US,en;q=0.9",
+        "Accept-Encoding": "gzip, deflate, br",
+        "DNT": "1"
+    },
+    
+    # Human-like behavior simulation
+    js_code="""
+        // Random mouse movements
+        const simulateHuman = () => {
+            const event = new MouseEvent('mousemove', {
+                clientX: Math.random() * window.innerWidth,
+                clientY: Math.random() * window.innerHeight
+            });
+            document.dispatchEvent(event);
+        };
+        setInterval(simulateHuman, 100 + Math.random() * 200);
+        
+        // Random scrolling
+        const randomScroll = () => {
+            const scrollY = Math.random() * (document.body.scrollHeight - window.innerHeight);
+            window.scrollTo(0, scrollY);
+        };
+        setTimeout(randomScroll, 500 + Math.random() * 1000);
+    """,
+    
+    # Delay to appear more human
+    delay_before_return_html=2.0
+)
+
+result = await crawler.arun("https://bot-protected-site.com", config=config)
+```
+
+**Expected Real-World Impact:**
+- **Enterprise Scraping**: Access previously blocked corporate sites and databases
+- **Market Research**: Gather data from competitor sites with protection
+- **Price Monitoring**: Track e-commerce sites that block automated access
+- **Content Aggregation**: Collect news and social media despite anti-bot measures
+- **Compliance Testing**: Verify your own site's bot protection effectiveness
+
+## 🧠 Memory Monitoring & Optimization
+
+**The Problem:** Long-running crawl sessions consuming excessive memory, especially when processing large batches or heavy JavaScript sites.
+
+**My Solution:** Built comprehensive memory monitoring and optimization utilities that track usage patterns and provide actionable insights.
+
+### Memory Tracking Implementation
+
+```python
+from crawl4ai.memory_utils import MemoryMonitor, get_memory_info
+
+# Monitor memory during crawling
+monitor = MemoryMonitor()
+
+async with AsyncWebCrawler() as crawler:
+    # Start monitoring
+    monitor.start_monitoring()
+    
+    # Perform memory-intensive operations
+    results = await crawler.arun_many([
+        "https://heavy-js-site.com",
+        "https://large-images-site.com", 
+        "https://dynamic-content-site.com"
+    ])
+    
+    # Get detailed memory report
+    memory_report = monitor.get_report()
+    print(f"Peak memory usage: {memory_report['peak_mb']:.1f} MB")
+    print(f"Memory efficiency: {memory_report['efficiency']:.1f}%")
+    
+    # Automatic cleanup suggestions
+    if memory_report['peak_mb'] > 1000:  # > 1GB
+        print("💡 Consider batch size optimization")
+        print("💡 Enable aggressive garbage collection")
+```
+
+**Expected Real-World Impact:**
+- **Production Stability**: Prevent memory-related crashes in long-running services
+- **Cost Optimization**: Right-size server resources based on actual usage
+- **Performance Tuning**: Identify memory bottlenecks and optimization opportunities
+- **Scalability Planning**: Understand memory patterns for horizontal scaling
+
+## 📊 Enhanced Table Extraction
+
+**The Problem:** Table data was accessed through the generic `result.media` interface, making DataFrame conversion cumbersome and unclear.
+
+**My Solution:** Dedicated `result.tables` interface with direct DataFrame conversion and improved detection algorithms.
+
+### New Table Access Pattern
+
+```python
+# Old way (deprecated)
+# tables_data = result.media.get('tables', [])
+
+# New way (v0.7.3+)
+result = await crawler.arun("https://site-with-tables.com")
+
+# Direct table access
+if result.tables:
+    print(f"Found {len(result.tables)} tables")
+    
+    # Convert to pandas DataFrame instantly
+    import pandas as pd
+    
+    for i, table in enumerate(result.tables):
+        df = pd.DataFrame(table['data'])
+        print(f"Table {i}: {df.shape[0]} rows × {df.shape[1]} columns")
+        print(df.head())
+        
+        # Table metadata
+        print(f"Source: {table.get('source_xpath', 'Unknown')}")
+        print(f"Headers: {table.get('headers', [])}")
+```
+
+**Expected Real-World Impact:**
+- **Data Analysis**: Faster transition from web data to analysis-ready DataFrames
+- **ETL Pipelines**: Cleaner integration with data processing workflows
+- **Reporting**: Simplified table extraction for automated reporting systems

+## 🐳 Docker: Flexible LLM Provider Configuration
+
+**The Problem:** Hardcoded LLM providers in Docker deployments. Want to switch from OpenAI to Groq? Rebuild and redeploy. Testing different models? Multiple Docker images.
+
+**My Solution:** Configure LLM providers via environment variables. Switch providers without touching code or rebuilding images.
+
+### Deployment Flexibility
+
+```bash
+# Option 1: Direct environment variables
+docker run -d \
+  -e LLM_PROVIDER="groq/llama-3.2-3b-preview" \
+  -e GROQ_API_KEY="your-key" \
+  -p 11235:11235 \
+  unclecode/crawl4ai:latest
+
+# Option 2: Using .llm.env file (recommended for production)
+# Create .llm.env file:
+# LLM_PROVIDER=openai/gpt-4o-mini
+# OPENAI_API_KEY=your-openai-key
+# GROQ_API_KEY=your-groq-key
+
+docker run -d \
+  --env-file .llm.env \
+  -p 11235:11235 \
+  unclecode/crawl4ai:latest
+```
+
+Override per request when needed:
+```python
+# Use default provider from .llm.env
+response = requests.post("http://localhost:11235/crawl", json={
+    "url": "https://example.com",
+    "extraction_strategy": {"type": "llm"}
+})
+
+# Override to use different provider for this specific request
+response = requests.post("http://localhost:11235/crawl", json={
+    "url": "https://complex-page.com",
+    "extraction_strategy": {
+        "type": "llm",
+        "provider": "openai/gpt-4"  # Override default
+    }
+})
+```
+
+**Expected Real-World Impact:**
+- **Cost Optimization**: Use cheaper models for simple tasks, premium for complex
+- **A/B Testing**: Compare provider performance without deployment changes
+- **Fallback Strategies**: Switch providers on-the-fly during outages
+- **Development Flexibility**: Test locally with one provider, deploy with another
+- **Secure Configuration**: Keep API keys in `.llm.env` file, not in commands
+
+## 🔧 Bug Fixes & Improvements
+
+This release includes several important bug fixes that improve stability and reliability:
+
+- **URL Matcher Fallback**: Fixed edge cases in URL pattern matching logic
+- **Memory Management**: Resolved memory leaks in long-running crawl sessions

+
+## 🚀 LLMTableExtraction: Revolutionary Table Processing
+
+**The Problem:** Complex tables with rowspan, colspan, nested structures, or massive datasets that traditional HTML parsing can't handle effectively. Large tables that exceed token limits crash extraction processes.
+
+**My Solution:** I developed LLMTableExtraction—an intelligent table extraction strategy that uses Large Language Models with automatic chunking to handle tables of any size and complexity.
+
+### Technical Implementation
+
+```python
+from crawl4ai import (
+    AsyncWebCrawler,
+    CrawlerRunConfig, 
+    LLMConfig,
+    LLMTableExtraction,
+    CacheMode
+)
+
+# Configure LLM for table extraction
+llm_config = LLMConfig(
+    provider="openai/gpt-4.1-mini",
+    api_token="env:OPENAI_API_KEY",
+    temperature=0.1,  # Low temperature for consistency
+    max_tokens=32000
+)
+
+# Create intelligent table extraction strategy
+table_strategy = LLMTableExtraction(
+    llm_config=llm_config,
+    verbose=True,
+    max_tries=2,
+    enable_chunking=True,           # Handle massive tables
+    chunk_token_threshold=5000,     # Smart chunking threshold
+    overlap_threshold=100,          # Maintain context between chunks
+    extraction_type="structured"    # Get structured data output
+)
+
+# Apply to crawler configuration
+config = CrawlerRunConfig(
+    table_extraction_strategy=table_strategy,
+    cache_mode=CacheMode.BYPASS
+)
+
+async with AsyncWebCrawler() as crawler:
+    # Extract complex tables with intelligence
+    result = await crawler.arun(
+        "https://en.wikipedia.org/wiki/List_of_countries_by_GDP", 
+        config=config
+    )
+    
+    # Access extracted tables directly
+    for i, table in enumerate(result.tables):
+        print(f"Table {i}: {len(table['data'])} rows × {len(table['headers'])} columns")
+        
+        # Convert to pandas DataFrame instantly
+        import pandas as pd
+        df = pd.DataFrame(table['data'], columns=table['headers'])
+        print(df.head())
+```
+
+**Intelligent Chunking for Massive Tables:**
+
+```python
+# Handle tables that exceed token limits
+large_table_strategy = LLMTableExtraction(
+    llm_config=llm_config,
+    enable_chunking=True,
+    chunk_token_threshold=3000,    # Conservative threshold
+    overlap_threshold=150,         # Preserve context
+    max_concurrent_chunks=3,       # Parallel processing
+    merge_strategy="intelligent"   # Smart chunk merging
+)
+
+# Process Wikipedia comparison tables, financial reports, etc.
+config = CrawlerRunConfig(
+    table_extraction_strategy=large_table_strategy,
+    # Target specific table containers
+    css_selector="div.wikitable, table.sortable",
+    delay_before_return_html=2.0
+)
+
+result = await crawler.arun(
+    "https://en.wikipedia.org/wiki/Comparison_of_operating_systems",
+    config=config
+)
+
+# Tables are automatically chunked, processed, and merged
+print(f"Extracted {len(result.tables)} complex tables")
+for table in result.tables:
+    print(f"Merged table: {len(table['data'])} total rows")
+```
+
+**Advanced Features:**
+
+- **Intelligent Chunking**: Automatically splits massive tables while preserving structure
+- **Context Preservation**: Overlapping chunks maintain column relationships
+- **Parallel Processing**: Concurrent chunk processing for speed
+- **Smart Merging**: Reconstructs complete tables from processed chunks
+- **Complex Structure Support**: Handles rowspan, colspan, nested tables
+- **Metadata Extraction**: Captures table context, captions, and relationships
+
+**Expected Real-World Impact:**
+- **Financial Analysis**: Extract complex earnings tables and financial statements
+- **Research & Academia**: Process large datasets from Wikipedia, research papers
+- **E-commerce**: Handle product comparison tables with complex layouts
+- **Government Data**: Extract census data, statistical tables from official sources
+- **Competitive Intelligence**: Process competitor pricing and feature tables
+
+## ⚡ Enhanced Concurrency: True Performance Gains
+
+**The Problem:** The `arun_many()` method wasn't achieving true concurrency for fast-completing tasks, leading to sequential processing bottlenecks in batch operations.
+
+**My Solution:** I implemented true concurrency improvements in the dispatcher that enable genuine parallel processing for fast-completing tasks.
+
+### Performance Optimization
+
+```python
+# Before v0.7.4: Sequential-like behavior for fast tasks
+# After v0.7.4: True concurrency
+
+async with AsyncWebCrawler() as crawler:
+    # These will now run with true concurrency
+    urls = [
+        "https://httpbin.org/delay/1",
+        "https://httpbin.org/delay/1", 
+        "https://httpbin.org/delay/1",
+        "https://httpbin.org/delay/1"
+    ]
+    
+    # Processes in truly parallel fashion
+    results = await crawler.arun_many(urls)
+    
+    # Performance improvement: ~4x faster for fast-completing tasks
+    print(f"Processed {len(results)} URLs with true concurrency")
+```
+
+**Expected Real-World Impact:**
+- **API Crawling**: 3-4x faster processing of REST endpoints and API documentation
+- **Batch URL Processing**: Significant speedup for large URL lists
+- **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
+
+## 🔧 Critical Stability Fixes
+
+### Browser Manager Race Condition Resolution
+
+**The Problem:** Concurrent page creation in persistent browser contexts caused "Target page/context closed" errors during high-concurrency operations.
+
+**My Solution:** Implemented thread-safe page creation with proper locking mechanisms.
+
+```python
+# Fixed: Safe concurrent page creation
+browser_config = BrowserConfig(
+    browser_type="chromium",
+    use_persistent_context=True,  # Now thread-safe
+    max_concurrent_sessions=10    # Safely handle concurrent requests
+)
+
+async with AsyncWebCrawler(config=browser_config) as crawler:
+    # These concurrent operations are now stable
+    tasks = [crawler.arun(url) for url in url_list]
+    results = await asyncio.gather(*tasks)  # No more race conditions
+```
+
+### Enhanced Browser Profiler
+
+**The Problem:** Inconsistent keyboard handling across platforms and unreliable quit mechanisms.
+
+**My Solution:** Cross-platform keyboard listeners with improved quit handling.
+
+### Advanced URL Processing
+
+**The Problem:** Raw URL formats (`raw://` and `raw:`) weren't properly handled, and base tag link resolution was incomplete.
+
+**My Solution:** Enhanced URL preprocessing and base tag support.
+
+```python
+# Now properly handles all URL formats
+urls = [
+    "https://example.com",
+    "raw://static-html-content", 
+    "raw:file://local-file.html"
+]
+
+# Base tag links are now correctly resolved
+config = CrawlerRunConfig(
+    include_links=True,  # Links properly resolved with base tags
+    resolve_absolute_urls=True
+)
+```
+
+## 🛡️ Enhanced Proxy Configuration
+
+**The Problem:** Proxy configuration only accepted specific formats, limiting flexibility.
+
+**My Solution:** Enhanced ProxyConfig to support both dictionary and string formats.
+
+```python
+# Multiple proxy configuration formats now supported
+from crawl4ai import BrowserConfig, ProxyConfig
+
+# String format
+proxy_config = ProxyConfig("http://proxy.example.com:8080")
+
+# Dictionary format  
+proxy_config = ProxyConfig({
+    "server": "http://proxy.example.com:8080",
+    "username": "user",
+    "password": "pass"
+})
+
+# Use with crawler
+browser_config = BrowserConfig(proxy_config=proxy_config)
+async with AsyncWebCrawler(config=browser_config) as crawler:
+    result = await crawler.arun("https://httpbin.org/ip")
+```
+

+## 7. Anti-Bot Features (Stealth Mode & Undetected Browser)
+
+Crawl4AI provides two powerful features to bypass bot detection:
+
+### 7.1 Stealth Mode
+
+Stealth mode uses playwright-stealth to modify browser fingerprints and behaviors. Enable it with a simple flag:
+
+```python
+browser_config = BrowserConfig(
+    enable_stealth=True,  # Activates stealth mode
+    headless=False
+)
+```
+
+**When to use**: Sites with basic bot detection (checking navigator.webdriver, plugins, etc.)
+
+### 7.2 Undetected Browser
+
+For advanced bot detection, use the undetected browser adapter:
+
+```python
+from crawl4ai import UndetectedAdapter
+from crawl4ai.async_crawler_strategy import AsyncPlaywrightCrawlerStrategy
+
+# Create undetected adapter
+adapter = UndetectedAdapter()
+strategy = AsyncPlaywrightCrawlerStrategy(
+    browser_config=browser_config,
+    browser_adapter=adapter
+)
+
+async with AsyncWebCrawler(crawler_strategy=strategy, config=browser_config) as crawler:
+    # Your crawling code
+```
+
+**When to use**: Sites with sophisticated bot detection (Cloudflare, DataDome, etc.)
+
+### 7.3 Combining Both
+
+For maximum evasion, combine stealth mode with undetected browser:
+
+```python
+browser_config = BrowserConfig(
+    enable_stealth=True,  # Enable stealth
+    headless=False
+)
+
+adapter = UndetectedAdapter()  # Use undetected browser
+```
+
+### Choosing the Right Approach
+
+| Detection Level | Recommended Approach |
+|----------------|---------------------|
+| No protection | Regular browser |
+| Basic checks | Regular + Stealth mode |
+| Advanced protection | Undetected browser |
+| Maximum evasion | Undetected + Stealth mode |
+
+**Best Practice**: Start with regular browser + stealth mode. Only use undetected browser if needed, as it may be slightly slower.
+
+See [Undetected Browser Mode](undetected-browser.md) for detailed examples.

-## 6. Summary
+## 6. URL-Specific Configurations
+
+When crawling diverse content types, you often need different configurations for different URLs. For example:
+- PDFs need specialized extraction
+- Blog pages benefit from content filtering
+- Dynamic sites need JavaScript execution
+- API endpoints need JSON parsing
+
+### 6.1 Basic URL Pattern Matching
+
+```python
+from crawl4ai import AsyncWebCrawler, CrawlerRunConfig, MatchMode
+from crawl4ai.processors.pdf import PDFContentScrapingStrategy
+from crawl4ai.extraction_strategy import JsonCssExtractionStrategy
+from crawl4ai.content_filter_strategy import PruningContentFilter
+from crawl4ai.markdown_generation_strategy import DefaultMarkdownGenerator
+
+async def crawl_mixed_content():
+    # Configure different strategies for different content
+    configs = [
+        # PDF files - specialized extraction
+        CrawlerRunConfig(
+            url_matcher="*.pdf",
+            scraping_strategy=PDFContentScrapingStrategy()
+        ),
+        
+        # Blog/article pages - content filtering
+        CrawlerRunConfig(
+            url_matcher=["*/blog/*", "*/article/*"],
+            markdown_generator=DefaultMarkdownGenerator(
+                content_filter=PruningContentFilter(threshold=0.48)
+            )
+        ),
+        
+        # Dynamic pages - JavaScript execution
+        CrawlerRunConfig(
+            url_matcher=lambda url: 'github.com' in url,
+            js_code="window.scrollTo(0, 500);"
+        ),
+        
+        # API endpoints - JSON extraction
+        CrawlerRunConfig(
+            url_matcher=lambda url: 'api' in url or url.endswith('.json'),
+            # Custome settings for JSON extraction
+        ),
+        
+        # Default config for everything else
+        CrawlerRunConfig()  # No url_matcher means it matches ALL URLs (fallback)
+    ]
+    
+    # Mixed URLs
+    urls = [
+        "https://www.w3.org/WAI/ER/tests/xhtml/testfiles/resources/pdf/dummy.pdf",
+        "https://blog.python.org/",
+        "https://github.com/microsoft/playwright",
+        "https://httpbin.org/json",
+        "https://example.com/"
+    ]
+    
+    async with AsyncWebCrawler() as crawler:
+        results = await crawler.arun_many(
+            urls=urls,
+            config=configs  # Pass list of configs
+        )
+        
+        for result in results:
+            print(f"{result.url}: {len(result.markdown)} chars")
+```
+
+### 6.2 Advanced Pattern Matching
+
+**Important**: A `CrawlerRunConfig` without `url_matcher` (or with `url_matcher=None`) matches ALL URLs. This makes it perfect as a default/fallback configuration.
+
+The `url_matcher` parameter supports three types of patterns:
+
+#### Glob Patterns (Strings)
+```python
+# Simple patterns
+"*.pdf"                    # Any PDF file
+"*/api/*"                  # Any URL with /api/ in path
+"https://*.example.com/*"  # Subdomain matching
+"*://example.com/blog/*"   # Any protocol
+```
+
+#### Custom Functions
+```python
+# Complex logic with lambdas
+lambda url: url.startswith('https://') and 'secure' in url
+lambda url: len(url) > 50 and url.count('/') > 5
+lambda url: any(domain in url for domain in ['api.', 'data.', 'feed.'])
+```
+
+#### Mixed Lists with AND/OR Logic
+```python
+# Combine multiple conditions
+CrawlerRunConfig(
+    url_matcher=[
+        "https://*",                        # Must be HTTPS
+        lambda url: 'internal' in url,      # Must contain 'internal'
+        lambda url: not url.endswith('.pdf') # Must not be PDF
+    ],
+    match_mode=MatchMode.AND  # ALL conditions must match
+)
+```
+
+### 6.3 Practical Example: News Site Crawler
+
+```python
+async def crawl_news_site():
+    dispatcher = MemoryAdaptiveDispatcher(
+        memory_threshold_percent=70.0,
+        rate_limiter=RateLimiter(base_delay=(1.0, 2.0))
+    )
+    
+    configs = [
+        # Homepage - light extraction
+        CrawlerRunConfig(
+            url_matcher=lambda url: url.rstrip('/') == 'https://news.ycombinator.com',
+            css_selector="nav, .headline",
+            extraction_strategy=None
+        ),
+        
+        # Article pages - full extraction
+        CrawlerRunConfig(
+            url_matcher="*/article/*",
+            extraction_strategy=CosineStrategy(
+                semantic_filter="article content",
+                word_count_threshold=100
+            ),
+            screenshot=True,
+            excluded_tags=["nav", "aside", "footer"]
+        ),
+        
+        # Author pages - metadata focus
+        CrawlerRunConfig(
+            url_matcher="*/author/*",
+            extraction_strategy=JsonCssExtractionStrategy({
+                "name": "h1.author-name",
+                "bio": ".author-bio",
+                "articles": "article.post-card h2"
+            })
+        ),
+        
+        # Everything else
+        CrawlerRunConfig()
+    ]
+    
+    async with AsyncWebCrawler() as crawler:
+        results = await crawler.arun_many(
+            urls=news_urls,
+            config=configs,
+            dispatcher=dispatcher
+        )
+```
+
+### 6.4 Best Practices
+
+1. **Order Matters**: Configs are evaluated in order - put specific patterns before general ones
+2. **Default Config Behavior**: 
+   - A config without `url_matcher` matches ALL URLs
+   - Always include a default config as the last item if you want to handle all URLs
+   - Without a default config, unmatched URLs will fail with "No matching configuration found"
+3. **Test Your Patterns**: Use the config's `is_match()` method to test patterns:
+   ```python
+   config = CrawlerRunConfig(url_matcher="*.pdf")
+   print(config.is_match("https://example.com/doc.pdf"))  # True
+   
+   default_config = CrawlerRunConfig()  # No url_matcher
+   print(default_config.is_match("https://any-url.com"))  # True - matches everything!
+   ```
+4. **Optimize for Performance**: 
+   - Disable JS for static content
+   - Skip screenshots for data APIs
+   - Use appropriate extraction strategies

+`PDFCrawlerStrategy` is an implementation of `AsyncCrawlerStrategy` designed specifically for PDF documents. Instead of interpreting the input URL as an HTML webpage, this strategy treats it as a pointer to a PDF file. It doesn't perform deep crawling or HTML parsing itself but rather prepares the PDF source for a dedicated PDF scraping strategy. Its primary role is to identify the PDF source (web URL or local file) and pass it along the processing pipeline in a way that `AsyncWebCrawler` can handle.
+
+### When to Use
+Use `PDFCrawlerStrategy` when you need to:
+- Process PDF files using the `AsyncWebCrawler`.
+- Handle PDFs from both web URLs (e.g., `https://example.com/document.pdf`) and local file paths (e.g., `file:///path/to/your/document.pdf`).
+- Integrate PDF content extraction into a unified `CrawlResult` object, allowing consistent handling of PDF data alongside web page data.
+
+### Key Methods and Their Behavior
+-   **`__init__(self, logger: AsyncLogger = None)`**:
+    -   Initializes the strategy.
+    -   `logger`: An optional `AsyncLogger` instance (from `crawl4ai.async_logger`) for logging purposes.
+-   **`async crawl(self, url: str, **kwargs) -> AsyncCrawlResponse`**:
+    -   This method is called by the `AsyncWebCrawler` during the `arun` process.
+    -   It takes the `url` (which should point to a PDF) and creates a minimal `AsyncCrawlResponse`.
+    -   The `html` attribute of this response is typically empty or a placeholder, as the actual PDF content processing is deferred to the `PDFContentScrapingStrategy` (or a similar PDF-aware scraping strategy).
+    -   It sets `response_headers` to indicate "application/pdf" and `status_code` to 200.
+-   **`async close(self)`**:
+    -   A method for cleaning up any resources used by the strategy. For `PDFCrawlerStrategy`, this is usually minimal.
+-   **`async __aenter__(self)` / `async __aexit__(self, exc_type, exc_val, exc_tb)`**:
+    -   Enables asynchronous context management for the strategy, allowing it to be used with `async with`.
+
+### Example Usage
+```python
+import asyncio
+from crawl4ai import AsyncWebCrawler, CrawlerRunConfig
+from crawl4ai.processors.pdf import PDFCrawlerStrategy, PDFContentScrapingStrategy
+
+async def main():
+    # Initialize the PDF crawler strategy
+    pdf_crawler_strategy = PDFCrawlerStrategy()
+
+    # PDFCrawlerStrategy is typically used in conjunction with PDFContentScrapingStrategy
+    # The scraping strategy handles the actual PDF content extraction
+    pdf_scraping_strategy = PDFContentScrapingStrategy()
+    run_config = CrawlerRunConfig(scraping_strategy=pdf_scraping_strategy)
+
+    async with AsyncWebCrawler(crawler_strategy=pdf_crawler_strategy) as crawler:
+        # Example with a remote PDF URL
+        pdf_url = "https://arxiv.org/pdf/2310.06825.pdf" # A public PDF from arXiv
+        
+        print(f"Attempting to process PDF: {pdf_url}")
+        result = await crawler.arun(url=pdf_url, config=run_config)
+
+        if result.success:
+            print(f"Successfully processed PDF: {result.url}")
+            print(f"Metadata Title: {result.metadata.get('title', 'N/A')}")
+            # Further processing of result.markdown, result.media, etc.
+            # would be done here, based on what PDFContentScrapingStrategy extracts.
+            if result.markdown and hasattr(result.markdown, 'raw_markdown'):
+                print(f"Extracted text (first 200 chars): {result.markdown.raw_markdown[:200]}...")
+            else:
+                print("No markdown (text) content extracted.")
+        else:
+            print(f"Failed to process PDF: {result.error_message}")
+
+if __name__ == "__main__":
+    asyncio.run(main())
+```
+
+### Pros and Cons
+**Pros:**
+-   Enables `AsyncWebCrawler` to handle PDF sources directly using familiar `arun` calls.
+-   Provides a consistent interface for specifying PDF sources (URLs or local paths).
+-   Abstracts the source handling, allowing a separate scraping strategy to focus on PDF content parsing.
+
+**Cons:**
+-   Does not perform any PDF data extraction itself; it strictly relies on a compatible scraping strategy (like `PDFContentScrapingStrategy`) to process the PDF.
+-   Has limited utility on its own; most of its value comes from being paired with a PDF-specific content scraping strategy.

+
+## `PDFContentScrapingStrategy`
+
+### Overview
+`PDFContentScrapingStrategy` is an implementation of `ContentScrapingStrategy` designed to extract text, metadata, and optionally images from PDF documents. It is intended to be used in conjunction with a crawler strategy that can provide it with a PDF source, such as `PDFCrawlerStrategy`. This strategy uses the `NaivePDFProcessorStrategy` internally to perform the low-level PDF parsing.
+
+### When to Use
+Use `PDFContentScrapingStrategy` when your `AsyncWebCrawler` (often configured with `PDFCrawlerStrategy`) needs to:
+-   Extract textual content page by page from a PDF document.
+-   Retrieve standard metadata embedded within the PDF (e.g., title, author, subject, creation date, page count).
+-   Optionally, extract images contained within the PDF pages. These images can be saved to a local directory or made available for further processing.
+-   Produce a `ScrapingResult` that can be converted into a `CrawlResult`, making PDF content accessible in a manner similar to HTML web content (e.g., text in `result.markdown`, metadata in `result.metadata`).
+
+### Key Configuration Attributes
+When initializing `PDFContentScrapingStrategy`, you can configure its behavior using the following attributes:
+-   **`extract_images: bool = False`**: If `True`, the strategy will attempt to extract images from the PDF.
+-   **`save_images_locally: bool = False`**: If `True` (and `extract_images` is also `True`), extracted images will be saved to disk in the `image_save_dir`. If `False`, image data might be available in another form (e.g., base64, depending on the underlying processor) but not saved as separate files by this strategy.
+-   **`image_save_dir: str = None`**: Specifies the directory where extracted images should be saved if `save_images_locally` is `True`. If `None`, a default or temporary directory might be used.
+-   **`batch_size: int = 4`**: Defines how many PDF pages are processed in a single batch. This can be useful for managing memory when dealing with very large PDF documents.
+-   **`logger: AsyncLogger = None`**: An optional `AsyncLogger` instance for logging.
+
+### Key Methods and Their Behavior
+-   **`__init__(self, save_images_locally: bool = False, extract_images: bool = False, image_save_dir: str = None, batch_size: int = 4, logger: AsyncLogger = None)`**:
+    -   Initializes the strategy with configurations for image handling, batch processing, and logging. It sets up an internal `NaivePDFProcessorStrategy` instance which performs the actual PDF parsing.
+-   **`scrap(self, url: str, html: str, **params) -> ScrapingResult`**:
+    -   This is the primary synchronous method called by the crawler (via `ascrap`) to process the PDF.
+    -   `url`: The path or URL to the PDF file (provided by `PDFCrawlerStrategy` or similar).
+    -   `html`: Typically an empty string when used with `PDFCrawlerStrategy`, as the content is a PDF, not HTML.
+    -   It first ensures the PDF is accessible locally (downloads it to a temporary file if `url` is remote).
+    -   It then uses its internal PDF processor to extract text, metadata, and images (if configured).
+    -   The extracted information is compiled into a `ScrapingResult` object:
+        -   `cleaned_html`: Contains an HTML-like representation of the PDF, where each page's content is often wrapped in a `<div>` with page number information.
+        -   `media`: A dictionary where `media["images"]` will contain information about extracted images if `extract_images` was `True`.
+        -   `links`: A dictionary where `links["urls"]` can contain URLs found within the PDF content.
+        -   `metadata`: A dictionary holding PDF metadata (e.g., title, author, num_pages).
+-   **`async ascrap(self, url: str, html: str, **kwargs) -> ScrapingResult`**:
+    -   The asynchronous version of `scrap`. Under the hood, it typically runs the synchronous `scrap` method in a separate thread using `asyncio.to_thread` to avoid blocking the event loop.
+-   **`_get_pdf_path(self, url: str) -> str`**:
+    -   A private helper method to manage PDF file access. If the `url` is remote (http/https), it downloads the PDF to a temporary local file and returns its path. If `url` indicates a local file (`file://` or a direct path), it resolves and returns the local path.
+
+### Example Usage
+```python
+import asyncio
+from crawl4ai import AsyncWebCrawler, CrawlerRunConfig
+from crawl4ai.processors.pdf import PDFCrawlerStrategy, PDFContentScrapingStrategy
+import os # For creating image directory
+
+async def main():
+    # Define the directory for saving extracted images
+    image_output_dir = "./my_pdf_images"
+    os.makedirs(image_output_dir, exist_ok=True)
+
+    # Configure the PDF content scraping strategy
+    # Enable image extraction and specify where to save them
+    pdf_scraping_cfg = PDFContentScrapingStrategy(
+        extract_images=True,
+        save_images_locally=True,
+        image_save_dir=image_output_dir,
+        batch_size=2 # Process 2 pages at a time for demonstration
+    )

+    # Configure the overall crawl run
+    run_cfg = CrawlerRunConfig(
+        scraping_strategy=pdf_scraping_cfg # Use our PDF scraping strategy
+    )
+
+    # Initialize the crawler with the PDF-specific crawler strategy
+    async with AsyncWebCrawler(crawler_strategy=pdf_crawler_cfg) as crawler:
+        pdf_url = "https://arxiv.org/pdf/2310.06825.pdf" # Example PDF
+        
+        print(f"Starting PDF processing for: {pdf_url}")
+        result = await crawler.arun(url=pdf_url, config=run_cfg)
+

+                print(f"\n--- Image Extraction ---")
+                print(f"Extracted {len(result.media['images'])} image(s).")
+                for i, img_info in enumerate(result.media["images"][:2]): # Show info for first 2 images
+                    print(f"  Image {i+1}:")
+                    print(f"    Page: {img_info.get('page')}")
+                    print(f"    Format: {img_info.get('format', 'N/A')}")
+                    if img_info.get('path'):
+                        print(f"    Saved at: {img_info.get('path')}")
+            else:
+                print("\nNo images were extracted (or extract_images was False).")
+        else:

+            print(f"Error: {result.error_message}")
+
+if __name__ == "__main__":
+    asyncio.run(main())
+```
+
+### Pros and Cons
+
+**Pros:**
+-   Provides a comprehensive way to extract text, metadata, and (optionally) images from PDF documents.
+-   Handles both remote PDFs (via URL) and local PDF files.
+-   Configurable image extraction allows saving images to disk or accessing their data.
+-   Integrates smoothly with the `CrawlResult` object structure, making PDF-derived data accessible in a way consistent with web-scraped data.
+-   The `batch_size` parameter can help in managing memory consumption when processing large or numerous PDF pages.
+
+**Cons:**
+-   Extraction quality and performance can vary significantly depending on the PDF's complexity, encoding, and whether it's image-based (scanned) or text-based.
+-   Image extraction can be resource-intensive (both CPU and disk space if `save_images_locally` is true).
+-   Relies on `NaivePDFProcessorStrategy` internally, which might have limitations with very complex layouts, encrypted PDFs, or forms compared to more sophisticated PDF parsing libraries. Scanned PDFs will not yield text unless an OCR step is performed (which is not part of this strategy by default).
+-   Link extraction from PDFs can be basic and depends on how hyperlinks are embedded in the document.

+# Undetected Browser Mode
+
+## Overview
+
+Crawl4AI offers two powerful anti-bot features to help you access websites with bot detection:
+
+1. **Stealth Mode** - Uses playwright-stealth to modify browser fingerprints and behaviors
+2. **Undetected Browser Mode** - Advanced browser adapter with deep-level patches for sophisticated bot detection
+
+This guide covers both features and helps you choose the right approach for your needs.
+
+## Anti-Bot Features Comparison
+
+| Feature | Regular Browser | Stealth Mode | Undetected Browser |
+|---------|----------------|--------------|-------------------|
+| WebDriver Detection | ❌ | ✅ | ✅ |
+| Navigator Properties | ❌ | ✅ | ✅ |
+| Plugin Emulation | ❌ | ✅ | ✅ |
+| CDP Detection | ❌ | Partial | ✅ |
+| Deep Browser Patches | ❌ | ❌ | ✅ |
+| Performance Impact | None | Minimal | Moderate |
+| Setup Complexity | None | None | Minimal |
+
+## When to Use Each Approach
+
+### Use Regular Browser + Stealth Mode When:
+- Sites have basic bot detection (checking navigator.webdriver, plugins, etc.)
+- You need good performance with basic protection
+- Sites check for common automation indicators
+
+### Use Undetected Browser When:
+- Sites employ sophisticated bot detection services (Cloudflare, DataDome, etc.)
+- Stealth mode alone isn't sufficient
+- You're willing to trade some performance for better evasion
+
+### Best Practice: Progressive Enhancement
+1. **Start with**: Regular browser + Stealth mode
+2. **If blocked**: Switch to Undetected browser
+3. **If still blocked**: Combine Undetected browser + Stealth mode
+
+## Stealth Mode
+
+Stealth mode is the simpler anti-bot solution that works with both regular and undetected browsers:
+
+```python
+from crawl4ai import AsyncWebCrawler, BrowserConfig
+
+# Enable stealth mode with regular browser
+browser_config = BrowserConfig(
+    enable_stealth=True,  # Simple flag to enable
+    headless=False       # Better for avoiding detection
+)
+
+async with AsyncWebCrawler(config=browser_config) as crawler:
+    result = await crawler.arun("https://example.com")
+```
+
+### What Stealth Mode Does:
+- Removes `navigator.webdriver` flag
+- Modifies browser fingerprints
+- Emulates realistic plugin behavior
+- Adjusts navigator properties
+- Fixes common automation leaks
+
+## Undetected Browser Mode
+
+For sites with sophisticated bot detection that stealth mode can't bypass, use the undetected browser adapter:
+
+### Key Features
+
+- **Drop-in Replacement**: Uses the same API as regular browser mode
+- **Enhanced Stealth**: Built-in patches to evade common detection methods
+- **Browser Adapter Pattern**: Seamlessly switch between regular and undetected modes
+- **Automatic Installation**: `crawl4ai-setup` installs all necessary browser dependencies
+
+### Quick Start
+
+```python
+import asyncio
+from crawl4ai import (
+    AsyncWebCrawler, 
+    BrowserConfig, 
+    CrawlerRunConfig,
+    UndetectedAdapter
+)
+from crawl4ai.async_crawler_strategy import AsyncPlaywrightCrawlerStrategy
+
+async def main():
+    # Create the undetected adapter
+    undetected_adapter = UndetectedAdapter()
+    
+    # Create browser config
+    browser_config = BrowserConfig(
+        headless=False,  # Headless mode can be detected easier
+        verbose=True,
+    )
+    
+    # Create the crawler strategy with undetected adapter
+    crawler_strategy = AsyncPlaywrightCrawlerStrategy(
+        browser_config=browser_config,
+        browser_adapter=undetected_adapter
+    )
+    
+    # Create the crawler with our custom strategy
+    async with AsyncWebCrawler(
+        crawler_strategy=crawler_strategy,
+        config=browser_config
+    ) as crawler:
+        # Your crawling code here
+        result = await crawler.arun(
+            url="https://example.com",
+            config=CrawlerRunConfig()
+        )
+        print(result.markdown[:500])
+
+asyncio.run(main())
+```
+
+## Combining Both Features
+
+For maximum evasion, combine stealth mode with undetected browser:
+
+```python
+from crawl4ai import AsyncWebCrawler, BrowserConfig, UndetectedAdapter
+from crawl4ai.async_crawler_strategy import AsyncPlaywrightCrawlerStrategy
+
+# Create browser config with stealth enabled
+browser_config = BrowserConfig(
+    enable_stealth=True,  # Enable stealth mode
+    headless=False
+)
+
+# Create undetected adapter
+adapter = UndetectedAdapter()
+
+# Create strategy with both features
+strategy = AsyncPlaywrightCrawlerStrategy(
+    browser_config=browser_config,
+    browser_adapter=adapter
+)
+
+async with AsyncWebCrawler(
+    crawler_strategy=strategy,
+    config=browser_config
+) as crawler:
+    result = await crawler.arun("https://protected-site.com")
+```
+
+## Examples
+
+### Example 1: Basic Stealth Mode
+
+```python
+import asyncio
+from crawl4ai import AsyncWebCrawler, BrowserConfig, CrawlerRunConfig
+
+async def test_stealth_mode():
+    # Simple stealth mode configuration
+    browser_config = BrowserConfig(
+        enable_stealth=True,
+        headless=False
+    )
+    
+    async with AsyncWebCrawler(config=browser_config) as crawler:
+        result = await crawler.arun(
+            url="https://bot.sannysoft.com",
+            config=CrawlerRunConfig(screenshot=True)
+        )
+        
+        if result.success:
+            print("✓ Successfully accessed bot detection test site")
+            # Save screenshot to verify detection results
+            if result.screenshot:
+                import base64
+                with open("stealth_test.png", "wb") as f:
+                    f.write(base64.b64decode(result.screenshot))
+                print("✓ Screenshot saved - check for green (passed) tests")
+
+asyncio.run(test_stealth_mode())
+```
+
+### Example 2: Undetected Browser Mode
+
+```python
+import asyncio
+from crawl4ai import (
+    AsyncWebCrawler,
+    BrowserConfig,
+    CrawlerRunConfig,
+    UndetectedAdapter
+)

+            ),
+            capture_console_messages=True,  # Test adapter console capture
+        )
+

+        result: CrawlResult = await crawler.arun(
+            url="https://www.helloworld.org",

+
+
+if __name__ == "__main__":
+    asyncio.run(main())
+```
+
+## Browser Adapter Pattern
+
+The undetected browser support is implemented using an adapter pattern, allowing seamless switching between different browser implementations:
+
+```python
+# Regular browser adapter (default)
+from crawl4ai import PlaywrightAdapter
+regular_adapter = PlaywrightAdapter()
+
+# Undetected browser adapter
+from crawl4ai import UndetectedAdapter
+undetected_adapter = UndetectedAdapter()
+```
+
+The adapter handles:
+- JavaScript execution
+- Console message capture
+- Error handling
+- Browser-specific optimizations
+
+## Best Practices
+
+1. **Avoid Headless Mode**: Detection is easier in headless mode
+   ```python
+   browser_config = BrowserConfig(headless=False)
+   ```
+
+2. **Use Reasonable Delays**: Don't rush through pages
+   ```python
+   crawler_config = CrawlerRunConfig(
+       wait_time=3.0,  # Wait 3 seconds after page load
+       delay_before_return_html=2.0  # Additional delay
+   )
+   ```
+
+3. **Rotate User Agents**: You can customize user agents
+   ```python
+   browser_config = BrowserConfig(
+       headers={"User-Agent": "your-user-agent"}
+   )
+   ```
+
+4. **Handle Failures Gracefully**: Some sites may still detect and block
+   ```python
+   if not result.success:
+       print(f"Crawl failed: {result.error_message}")
+   ```
+
+## Advanced Usage Tips
+
+### Progressive Detection Handling
+
+```python
+async def crawl_with_progressive_evasion(url):
+    # Step 1: Try regular browser with stealth
+    browser_config = BrowserConfig(
+        enable_stealth=True,
+        headless=False
+    )
+    
+    async with AsyncWebCrawler(config=browser_config) as crawler:
+        result = await crawler.arun(url)
+        if result.success and "Access Denied" not in result.html:
+            return result
+    
+    # Step 2: If blocked, try undetected browser
+    print("Regular + stealth blocked, trying undetected browser...")
+    
+    adapter = UndetectedAdapter()
+    strategy = AsyncPlaywrightCrawlerStrategy(
+        browser_config=browser_config,
+        browser_adapter=adapter
+    )
+    
+    async with AsyncWebCrawler(
+        crawler_strategy=strategy,
+        config=browser_config
+    ) as crawler:
+        result = await crawler.arun(url)
+        return result
+```
+
+## Installation
+
+The undetected browser dependencies are automatically installed when you run:
+
+```bash
+crawl4ai-setup
+```
+
+This command installs all necessary browser dependencies for both regular and undetected modes.
+
+## Limitations
+
+- **Performance**: Slightly slower than regular mode due to additional patches
+- **Headless Detection**: Some sites can still detect headless mode
+- **Resource Usage**: May use more resources than regular mode
+- **Not 100% Guaranteed**: Advanced anti-bot services are constantly evolving
+
+## Troubleshooting
+
+### Browser Not Found
+
+Run the setup command:
+```bash
+crawl4ai-setup
+```
+
+### Detection Still Occurring
+
+Try combining with other features:
+```python
+crawler_config = CrawlerRunConfig(
+    simulate_user=True,  # Add user simulation
+    magic=True,  # Enable magic mode
+    wait_time=5.0,  # Longer waits
+)
+```
+
+### Performance Issues
+
+If experiencing slow performance:
+```python
+# Use selective undetected mode only for protected sites
+if is_protected_site(url):
+    adapter = UndetectedAdapter()
+else:
+    adapter = PlaywrightAdapter()  # Default adapter
+```
+
+## Future Plans
+
+**Note**: In future versions of Crawl4AI, we may enable stealth mode and undetected browser by default to provide better out-of-the-box success rates. For now, users should explicitly enable these features when needed.
+
+## Conclusion
+
+Crawl4AI provides flexible anti-bot solutions:
+
+1. **Start Simple**: Use regular browser + stealth mode for most sites
+2. **Escalate if Needed**: Switch to undetected browser for sophisticated protection
+3. **Combine for Maximum Effect**: Use both features together when facing the toughest challenges
+
+Remember:
+- Always respect robots.txt and website terms of service
+- Use appropriate delays to avoid overwhelming servers
+- Consider the performance trade-offs of each approach
+- Test progressively to find the minimum necessary evasion level

+### URL-Specific Configurations
+
+Instead of using one config for all URLs, provide a list of configs with `url_matcher` patterns:

+```python
+from crawl4ai import CrawlerRunConfig, MatchMode
+from crawl4ai.processors.pdf import PDFContentScrapingStrategy
+from crawl4ai.extraction_strategy import JsonCssExtractionStrategy
+from crawl4ai.content_filter_strategy import PruningContentFilter

+# Dynamic pages - JavaScript execution
+github_config = CrawlerRunConfig(
+    url_matcher=lambda url: 'github.com' in url,
+    js_code="window.scrollTo(0, 500);"
+)
+
+# API endpoints - JSON extraction
+api_config = CrawlerRunConfig(
+    url_matcher=lambda url: 'api' in url or url.endswith('.json'),
+    # Custome settings for JSON extraction
+)
+
+# Default fallback config
+default_config = CrawlerRunConfig()  # No url_matcher means it never matches except as fallback
+
+# Pass the list of configs - first match wins!
+results = await crawler.arun_many(
+    urls=[
+        "https://www.w3.org/WAI/ER/tests/xhtml/testfiles/resources/pdf/dummy.pdf",  # → pdf_config
+        "https://blog.python.org/",  # → blog_config
+        "https://github.com/microsoft/playwright",  # → github_config
+        "https://httpbin.org/json",  # → api_config
+        "https://example.com/"  # → default_config
+    ],
+    config=[pdf_config, blog_config, github_config, api_config, default_config]
+)
+```
+
+**URL Matching Features**:
+- **String patterns**: `"*.pdf"`, `"*/blog/*"`, `"*python.org*"`
+- **Function matchers**: `lambda url: 'api' in url`
+- **Mixed patterns**: Combine strings and functions with `MatchMode.OR` or `MatchMode.AND`
+- **First match wins**: Configs are evaluated in order
+
 **Key Points**:
 - Each URL is processed by the same or separate sessions, depending on the dispatcher’s strategy.
 - `dispatch_result` in each `CrawlResult` (if using concurrency) can hold memory and timing info.  
 - If you need to handle authentication or session IDs, pass them in each individual task or within your run config.
+- **Important**: Always include a default config (without `url_matcher`) as the last item if you want to handle all URLs. Otherwise, unmatched URLs will fail.

-### [Crawl4AI v0.5.0: Deep Crawling, Scalability, and a New CLI!](releases/0.5.0.md)
-
-My dear friends and crawlers, there you go, this is the release of Crawl4AI v0.5.0! This release brings a wealth of new features, performance improvements, and a more streamlined developer experience.  Here's a breakdown of what's new:
-
-**Major New Features:**
-
-*   **Deep Crawling:** Explore entire websites with configurable strategies (BFS, DFS, Best-First).  Define custom filters and URL scoring for targeted crawls.
-*   **Memory-Adaptive Dispatcher:**  Handle large-scale crawls with ease!  Our new dispatcher dynamically adjusts concurrency based on available memory and includes built-in rate limiting.
-*   **Multiple Crawler Strategies:** Choose between the full-featured Playwright browser-based crawler or a new, *much* faster HTTP-only crawler for simpler tasks.
-*   **Docker Deployment:**  Deploy Crawl4AI as a scalable, self-contained service with built-in API endpoints and optional JWT authentication.
-*   **Command-Line Interface (CLI):**  Interact with Crawl4AI directly from your terminal.  Crawl, configure, and extract data with simple commands.
-*   **LLM Configuration (`LLMConfig`):** A new, unified way to configure LLM providers (OpenAI, Anthropic, Ollama, etc.) for extraction, filtering, and schema generation.  Simplifies API key management and switching between models.
-
-**Minor Updates & Improvements:**
-
-*   **LXML Scraping Mode:** Faster HTML parsing with `LXMLWebScrapingStrategy`.
-*   **Proxy Rotation:** Added `ProxyRotationStrategy` with a `RoundRobinProxyStrategy` implementation.
-*   **PDF Processing:** Extract text, images, and metadata from PDF files.
-*   **URL Redirection Tracking:**  Automatically follows and records redirects.
-*   **Robots.txt Compliance:**  Optionally respect website crawling rules.
-*   **LLM-Powered Schema Generation:**  Automatically create extraction schemas using an LLM.
-*   **`LLMContentFilter`:** Generate high-quality, focused markdown using an LLM.
-*   **Improved Error Handling & Stability:** Numerous bug fixes and performance enhancements.
-*   **Enhanced Documentation:**  Updated guides and examples.
-
-**Breaking Changes & Migration:**
-
-This release includes several breaking changes to improve the library's structure and consistency.  Here's what you need to know:
-
-*   **`arun_many()` Behavior:** Now uses the `MemoryAdaptiveDispatcher` by default.  The return type depends on the `stream` parameter in `CrawlerRunConfig`.  Adjust code that relied on unbounded concurrency.
-*   **`max_depth` Location:** Moved to `CrawlerRunConfig` and now controls *crawl depth*.
-*   **Deep Crawling Imports:**  Import `DeepCrawlStrategy` and related classes from `crawl4ai.deep_crawling`.
-*   **`BrowserContext` API:**  Updated; the old `get_context` method is deprecated.
-*   **Optional Model Fields:** Many data model fields are now optional.  Handle potential `None` values.
-*   **`ScrapingMode` Enum:** Replaced with strategy pattern (`WebScrapingStrategy`, `LXMLWebScrapingStrategy`).
-*   **`content_filter` Parameter:** Removed from `CrawlerRunConfig`. Use extraction strategies or markdown generators with filters.
-*   **Removed Functionality:** The synchronous `WebCrawler`, the old CLI, and docs management tools have been removed.
-*   **Docker:**  Significant changes to deployment.  See the [Docker documentation](../deploy/docker/README.md).
-*   **`ssl_certificate.json`:** This file has been removed.
-* **Config**: FastFilterChain has been replaced with FilterChain
-* **Deep-Crawl**: DeepCrawlStrategy.arun now returns Union[CrawlResultT, List[CrawlResultT], AsyncGenerator[CrawlResultT, None]]
-* **Proxy**: Removed synchronous WebCrawler support and related rate limiting configurations
-*   **LLM Parameters:** Use the new `LLMConfig` object instead of passing `provider`, `api_token`, `base_url`, and `api_base` directly to `LLMExtractionStrategy` and `LLMContentFilter`.
-
-**In short:** Update imports, adjust `arun_many()` usage, check for optional fields, and review the Docker deployment guide.
-

+# 🚀 Crawl4AI v0.7.0: The Adaptive Intelligence Update
+
+*January 28, 2025 • 10 min read*
+
+---
+
+Today I'm releasing Crawl4AI v0.7.0—the Adaptive Intelligence Update. This release introduces fundamental improvements in how Crawl4AI handles modern web complexity through adaptive learning, intelligent content discovery, and advanced extraction capabilities.
+
+## 🎯 What's New at a Glance
+
+- **Adaptive Crawling**: Your crawler now learns and adapts to website patterns
+- **Virtual Scroll Support**: Complete content extraction from infinite scroll pages
+- **Link Preview with Intelligent Scoring**: Intelligent link analysis and prioritization
+- **Async URL Seeder**: Discover thousands of URLs in seconds with intelligent filtering
+- **Performance Optimizations**: Significant speed and memory improvements
+
+## 🧠 Adaptive Crawling: Intelligence Through Pattern Learning
+
+**The Problem:** Websites change. Class names shift. IDs disappear. Your carefully crafted selectors break at 3 AM, and you wake up to empty datasets and angry stakeholders.
+
+**My Solution:** I implemented an adaptive learning system that observes patterns, builds confidence scores, and adjusts extraction strategies on the fly. It's like having a junior developer who gets better at their job with every page they scrape.
+
+### Technical Deep-Dive
+
+The Adaptive Crawler maintains a persistent state for each domain, tracking:
+- Pattern success rates
+- Selector stability over time  
+- Content structure variations
+- Extraction confidence scores
+
+```python
+from crawl4ai import AsyncWebCrawler, AdaptiveCrawler, AdaptiveConfig
+import asyncio
+
+async def main():
+    
+    # Configure adaptive crawler
+    config = AdaptiveConfig(
+        strategy="statistical",  # or "embedding" for semantic understanding
+        max_pages=10,
+        confidence_threshold=0.7,  # Stop at 70% confidence
+        top_k_links=3,  # Follow top 3 links per page
+        min_gain_threshold=0.05  # Need 5% information gain to continue
+    )
+    
+    async with AsyncWebCrawler(verbose=False) as crawler:
+        adaptive = AdaptiveCrawler(crawler, config)
+        
+        print("Starting adaptive crawl about Python decorators...")
+        result = await adaptive.digest(
+            start_url="https://docs.python.org/3/glossary.html",
+            query="python decorators functions wrapping"
+        )
+        
+        print(f"\n✅ Crawling Complete!")
+        print(f"• Confidence Level: {adaptive.confidence:.0%}")
+        print(f"• Pages Crawled: {len(result.crawled_urls)}")
+        print(f"• Knowledge Base: {len(adaptive.state.knowledge_base)} documents")
+        
+        # Get most relevant content
+        relevant = adaptive.get_relevant_content(top_k=3)
+        print(f"\nMost Relevant Pages:")
+        for i, page in enumerate(relevant, 1):
+            print(f"{i}. {page['url']} (relevance: {page['score']:.2%})")
+
+asyncio.run(main())
+```
+
+**Expected Real-World Impact:**
+- **News Aggregation**: Maintain 95%+ extraction accuracy even as news sites update their templates
+- **E-commerce Monitoring**: Track product changes across hundreds of stores without constant maintenance
+- **Research Data Collection**: Build robust academic datasets that survive website redesigns
+- **Reduced Maintenance**: Cut selector update time by 80% for frequently-changing sites
+
+## 🌊 Virtual Scroll: Complete Content Capture
+
+**The Problem:** Modern web apps only render what's visible. Scroll down, new content appears, old content vanishes into the void. Traditional crawlers capture that first viewport and miss 90% of the content. It's like reading only the first page of every book.
+
+**My Solution:** I built Virtual Scroll support that mimics human browsing behavior, capturing content as it loads and preserving it before the browser's garbage collector strikes.
+
+### Implementation Details
+
+```python
+from crawl4ai import VirtualScrollConfig
+
+# For social media feeds (Twitter/X style)
+twitter_config = VirtualScrollConfig(
+    container_selector="[data-testid='primaryColumn']",
+    scroll_count=20,                    # Number of scrolls
+    scroll_by="container_height",       # Smart scrolling by container size
+    wait_after_scroll=1.0              # Let content load
+)
+
+# For e-commerce product grids (Instagram style)
+grid_config = VirtualScrollConfig(
+    container_selector="main .product-grid",
+    scroll_count=30,
+    scroll_by=800,                     # Fixed pixel scrolling
+    wait_after_scroll=1.5              # Images need time
+)
+
+# For news feeds with lazy loading
+news_config = VirtualScrollConfig(
+    container_selector=".article-feed",
+    scroll_count=50,
+    scroll_by="page_height",           # Viewport-based scrolling
+    wait_after_scroll=0.5              # Wait for content to load
+)
+
+# Use it in your crawl
+async with AsyncWebCrawler() as crawler:
+    result = await crawler.arun(
+        "https://twitter.com/trending",
+        config=CrawlerRunConfig(
+            virtual_scroll_config=twitter_config,
+            # Combine with other features
+            extraction_strategy=JsonCssExtractionStrategy({
+                "tweets": {
+                    "selector": "[data-testid='tweet']",
+                    "fields": {
+                        "text": {"selector": "[data-testid='tweetText']", "type": "text"},
+                        "likes": {"selector": "[data-testid='like']", "type": "text"}
+                    }
+                }
+            })
+        )
+    )
+    
+    print(f"Captured {len(result.extracted_content['tweets'])} tweets")
+```
+
+**Key Capabilities:**
+- **DOM Recycling Awareness**: Detects and handles virtual DOM element recycling
+- **Smart Scroll Physics**: Three modes - container height, page height, or fixed pixels
+- **Content Preservation**: Captures content before it's destroyed
+- **Intelligent Stopping**: Stops when no new content appears
+- **Memory Efficient**: Streams content instead of holding everything in memory
+
+**Expected Real-World Impact:**
+- **Social Media Analysis**: Capture entire Twitter threads with hundreds of replies, not just top 10
+- **E-commerce Scraping**: Extract 500+ products from infinite scroll catalogs vs. 20-50 with traditional methods  
+- **News Aggregation**: Get all articles from modern news sites, not just above-the-fold content
+- **Research Applications**: Complete data extraction from academic databases using virtual pagination
+
+## 🔗 Link Preview: Intelligent Link Analysis and Scoring
+
+**The Problem:** You crawl a page and get 200 links. Which ones matter? Which lead to the content you actually want? Traditional crawlers force you to follow everything or build complex filters.
+
+**My Solution:** I implemented a three-layer scoring system that analyzes links like a human would—considering their position, context, and relevance to your goals.
+
+### Intelligent Link Analysis and Scoring
+
+```python
+import asyncio
+from crawl4ai import CrawlerRunConfig, CacheMode, AsyncWebCrawler
+from crawl4ai.adaptive_crawler import LinkPreviewConfig
+
+async def main():
+    # Configure intelligent link analysis
+    link_config = LinkPreviewConfig(
+        include_internal=True,
+        include_external=False,
+        max_links=10,
+        concurrency=5,
+        query="python tutorial",  # For contextual scoring
+        score_threshold=0.3,
+        verbose=True
+    )
+    # Use in your crawl
+    async with AsyncWebCrawler() as crawler:
+        result = await crawler.arun(
+            "https://www.geeksforgeeks.org/",
+            config=CrawlerRunConfig(
+                link_preview_config=link_config,
+                score_links=True,  # Enable intrinsic scoring
+                cache_mode=CacheMode.BYPASS
+            )
+        )
+
+        # Access scored and sorted links
+        if result.success and result.links:
+            for link in result.links.get("internal", []):
+                text = link.get('text', 'No text')[:40]
+                print(

+                )
+
+asyncio.run(main())
+```
+
+**Scoring Components:**
+
+1. **Intrinsic Score**: Based on link quality indicators
+   - Position on page (navigation, content, footer)
+   - Link attributes (rel, title, class names)
+   - Anchor text quality and length
+   - URL structure and depth
+
+2. **Contextual Score**: Relevance to your query using BM25 algorithm
+   - Keyword matching in link text and title
+   - Meta description analysis
+   - Content preview scoring
+
+3. **Total Score**: Combined score for final ranking
+
+**Expected Real-World Impact:**
+- **Research Efficiency**: Find relevant papers 10x faster by following only high-score links
+- **Competitive Analysis**: Automatically identify important pages on competitor sites
+- **Content Discovery**: Build topic-focused crawlers that stay on track
+- **SEO Audits**: Identify and prioritize high-value internal linking opportunities
+
+## 🎣 Async URL Seeder: Automated URL Discovery at Scale
+
+**The Problem:** You want to crawl an entire domain but only have the homepage. Or worse, you want specific content types across thousands of pages. Manual URL discovery? That's a job for machines, not humans.
+
+**My Solution:** I built Async URL Seeder—a turbocharged URL discovery engine that combines multiple sources with intelligent filtering and relevance scoring.
+
+### Technical Architecture
+
+```python
+import asyncio
+from crawl4ai import AsyncUrlSeeder, SeedingConfig
+
+async def main():
+    async with AsyncUrlSeeder() as seeder:
+        # Discover Python tutorial URLs
+        config = SeedingConfig(
+            source="sitemap",  # Use sitemap
+            pattern="*python*",  # URL pattern filter
+            extract_head=True,  # Get metadata
+            query="python tutorial",  # For relevance scoring
+            scoring_method="bm25",
+            score_threshold=0.2,
+            max_urls=10
+        )
+        
+        print("Discovering Python async tutorial URLs...")
+        urls = await seeder.urls("https://www.geeksforgeeks.org/", config)
+        
+        print(f"\n✅ Found {len(urls)} relevant URLs:")
+        for i, url_info in enumerate(urls[:5], 1):
+            print(f"\n{i}. {url_info['url']}")
+            if url_info.get('relevance_score'):
+                print(f"   Relevance: {url_info['relevance_score']:.3f}")
+            if url_info.get('head_data', {}).get('title'):
+                print(f"   Title: {url_info['head_data']['title'][:60]}...")
+
+asyncio.run(main())
+```
+
+**Discovery Methods:**
+- **Sitemap Mining**: Parses robots.txt and all linked sitemaps
+- **Common Crawl**: Queries the Common Crawl index for historical URLs
+- **Intelligent Crawling**: Follows links with smart depth control
+- **Pattern Analysis**: Learns URL structures and generates variations
+
+**Expected Real-World Impact:**
+- **Migration Projects**: Discover 10,000+ URLs from legacy sites in under 60 seconds
+- **Market Research**: Map entire competitor ecosystems automatically
+- **Academic Research**: Build comprehensive datasets without manual URL collection
+- **SEO Audits**: Find every indexable page with content scoring
+- **Content Archival**: Ensure no content is left behind during site migrations
+
+## ⚡ Performance Optimizations
+
+This release includes significant performance improvements through optimized resource handling, better concurrency management, and reduced memory footprint.
+
+### What We Optimized
+
+```python
+# Optimized crawling with v0.7.0 improvements
+results = []
+for url in urls:
+    result = await crawler.arun(
+        url,
+        config=CrawlerRunConfig(
+            # Performance optimizations
+            wait_until="domcontentloaded",  # Faster than networkidle
+            cache_mode=CacheMode.ENABLED    # Enable caching
+        )
+    )
+    results.append(result)
+```
+
+**Performance Gains:**
+- **Startup Time**: 70% faster browser initialization
+- **Page Loading**: 40% reduction with smart resource blocking
+- **Extraction**: 3x faster with compiled CSS selectors
+- **Memory Usage**: 60% reduction with streaming processing
+- **Concurrent Crawls**: Handle 5x more parallel requests
+
+
+## 🔧 Important Changes
+
+### Breaking Changes
+- `link_extractor` renamed to `link_preview` (better reflects functionality)
+- Minimum Python version now 3.9
+- `CrawlerConfig` split into `CrawlerRunConfig` and `BrowserConfig`
+
+### Migration Guide
+```python
+# Old (v0.6.x)
+from crawl4ai import CrawlerConfig
+config = CrawlerConfig(timeout=30000)
+
+# New (v0.7.0)
+from crawl4ai import CrawlerRunConfig, BrowserConfig
+browser_config = BrowserConfig(timeout=30000)
+run_config = CrawlerRunConfig(cache_mode=CacheMode.BYPASS)
+```
+
+## 🤖 Coming Soon: Intelligent Web Automation

+# 🚀 Crawl4AI v0.7.3: The Multi-Config Intelligence Update
+
+*August 6, 2025 • 5 min read*
+
+---
+
+Today I'm releasing Crawl4AI v0.7.3—the Multi-Config Intelligence Update. This release brings smarter URL-specific configurations, flexible Docker deployments, important bug fixes, and documentation improvements that make Crawl4AI more robust and production-ready.
+
+## 🎯 What's New at a Glance
+
+- **Multi-URL Configurations**: Different crawling strategies for different URL patterns in a single batch
+- **Flexible Docker LLM Providers**: Configure LLM providers via environment variables
+- **Bug Fixes**: Resolved several critical issues for better stability
+- **Documentation Updates**: Clearer examples and improved API documentation
+
+## 🎨 Multi-URL Configurations: One Size Doesn't Fit All
+
+**The Problem:** You're crawling a mix of documentation sites, blogs, and API endpoints. Each needs different handling—caching for docs, fresh content for news, structured extraction for APIs. Previously, you'd run separate crawls or write complex conditional logic.
+
+**My Solution:** I implemented URL-specific configurations that let you define different strategies for different URL patterns in a single crawl batch. First match wins, with optional fallback support.
+
+### Technical Implementation
+
+```python
+from crawl4ai import AsyncWebCrawler, CrawlerRunConfig, MatchMode
+
+# Define specialized configs for different content types
+configs = [
+    # Documentation sites - aggressive caching, include links
+    CrawlerRunConfig(
+        url_matcher=["*docs*", "*documentation*"],
+        cache_mode="write",
+        markdown_generator_options={"include_links": True}
+    ),
+    
+    # News/blog sites - fresh content, scroll for lazy loading
+    CrawlerRunConfig(
+        url_matcher=lambda url: 'blog' in url or 'news' in url,
+        cache_mode="bypass",
+        js_code="window.scrollTo(0, document.body.scrollHeight/2);"
+    ),
+    
+    # API endpoints - structured extraction
+    CrawlerRunConfig(
+        url_matcher=["*.json", "*api*"],
+        extraction_strategy=LLMExtractionStrategy(
+            provider="openai/gpt-4o-mini",
+            extraction_type="structured"
+        )
+    ),
+    
+    # Default fallback for everything else
+    CrawlerRunConfig()  # No url_matcher = matches everything
+]
+
+# Crawl multiple URLs with appropriate configs
+async with AsyncWebCrawler() as crawler:
+    results = await crawler.arun_many(
+        urls=[
+            "https://docs.python.org/3/",      # → Uses documentation config
+            "https://blog.python.org/",        # → Uses blog config  
+            "https://api.github.com/users",    # → Uses API config
+            "https://example.com/"             # → Uses default config
+        ],
+        config=configs
+    )
+```
+
+**Matching Capabilities:**
+- **String Patterns**: Wildcards like `"*.pdf"`, `"*/blog/*"`
+- **Function Matchers**: Lambda functions for complex logic
+- **Mixed Matchers**: Combine strings and functions with AND/OR logic
+- **Fallback Support**: Default config when nothing matches
+
+**Expected Real-World Impact:**
+- **Mixed Content Sites**: Handle blogs, docs, and downloads in one crawl
+- **Multi-Domain Crawling**: Different strategies per domain without separate runs
+- **Reduced Complexity**: No more if/else forests in your extraction code
+- **Better Performance**: Each URL gets exactly the processing it needs
+
+## 🐳 Docker: Flexible LLM Provider Configuration
+
+**The Problem:** Hardcoded LLM providers in Docker deployments. Want to switch from OpenAI to Groq? Rebuild and redeploy. Testing different models? Multiple Docker images.
+
+**My Solution:** Configure LLM providers via environment variables. Switch providers without touching code or rebuilding images.
+
+### Deployment Flexibility
+
+```bash
+# Option 1: Direct environment variables
+docker run -d \
+  -e LLM_PROVIDER="groq/llama-3.2-3b-preview" \
+  -e GROQ_API_KEY="your-key" \
+  -p 11235:11235 \
+  unclecode/crawl4ai:latest
+
+# Option 2: Using .llm.env file (recommended for production)
+# Create .llm.env file:
+# LLM_PROVIDER=openai/gpt-4o-mini
+# OPENAI_API_KEY=your-openai-key
+# GROQ_API_KEY=your-groq-key
+
+docker run -d \
+  --env-file .llm.env \
+  -p 11235:11235 \
+  unclecode/crawl4ai:latest
+```
+
+Override per request when needed:
+```python
+# Use default provider from .llm.env
+response = requests.post("http://localhost:11235/crawl", json={
+    "url": "https://example.com",
+    "extraction_strategy": {"type": "llm"}
+})
+
+# Override to use different provider for this specific request
+response = requests.post("http://localhost:11235/crawl", json={
+    "url": "https://complex-page.com",
+    "extraction_strategy": {
+        "type": "llm",
+        "provider": "openai/gpt-4"  # Override default
+    }
+})
+```
+
+**Expected Real-World Impact:**
+- **Cost Optimization**: Use cheaper models for simple tasks, premium for complex
+- **A/B Testing**: Compare provider performance without deployment changes
+- **Fallback Strategies**: Switch providers on-the-fly during outages
+- **Development Flexibility**: Test locally with one provider, deploy with another
+- **Secure Configuration**: Keep API keys in `.llm.env` file, not in commands
+
+## 🔧 Bug Fixes & Improvements
+
+This release includes several important bug fixes that improve stability and reliability:
+
+- **URL Matcher Fallback**: Fixed edge cases in URL pattern matching logic
+- **Memory Management**: Resolved memory leaks in long-running crawl sessions
+- **Sitemap Processing**: Fixed redirect handling in sitemap fetching
+- **Table Extraction**: Improved table detection and extraction accuracy
+- **Error Handling**: Better error messages and recovery from network failures
+
+## 📚 Documentation Enhancements
+
+Based on community feedback, we've updated:
+- Clearer examples for multi-URL configuration
+- Improved CrawlResult documentation with all available fields
+- Fixed typos and inconsistencies across documentation
+- Added real-world URLs in examples for better understanding
+- New comprehensive demo showcasing all v0.7.3 features

 ## 6. Scraping Modes
 
-Crawl4AI provides two different scraping strategies for HTML content processing: `WebScrapingStrategy` (BeautifulSoup-based, default) and `LXMLWebScrapingStrategy` (LXML-based). The LXML strategy offers significantly better performance, especially for large HTML documents.
+Crawl4AI uses `LXMLWebScrapingStrategy` (LXML-based) as the default scraping strategy for HTML content processing. This strategy offers excellent performance, especially for large HTML documents.
+
+**Note:** For backward compatibility, `WebScrapingStrategy` is still available as an alias for `LXMLWebScrapingStrategy`.
 
 ```python
 from crawl4ai import AsyncWebCrawler, CrawlerRunConfig, LXMLWebScrapingStrategy

-        scraping_strategy=LXMLWebScrapingStrategy()  # Faster alternative to default BeautifulSoup

 ### Performance Considerations
 
-The LXML strategy can be up to 10-20x faster than BeautifulSoup strategy, particularly when processing large HTML documents. However, please note:
+The LXML strategy provides excellent performance, particularly when processing large HTML documents, offering up to 10-20x faster processing compared to BeautifulSoup-based approaches.
 
-1. LXML strategy is currently experimental
-2. In some edge cases, the parsing results might differ slightly from BeautifulSoup
-3. If you encounter any inconsistencies between LXML and BeautifulSoup results, please [raise an issue](https://github.com/codeium/crawl4ai/issues) with a reproducible example
+Benefits of LXML strategy:
+- Fast processing of large HTML documents (especially >100KB)
+- Efficient memory usage
+- Good handling of well-formed HTML
+- Robust table detection and extraction
 
-Choose LXML strategy when:
-- Processing large HTML documents (recommended for >100KB)
-- Performance is critical
-- Working with well-formed HTML
+### Backward Compatibility
 
-Stick to BeautifulSoup strategy (default) when:
-- Maximum compatibility is needed
-- Working with malformed HTML
-- Exact parsing behavior is critical
+For users upgrading from earlier versions:
+- `WebScrapingStrategy` is now an alias for `LXMLWebScrapingStrategy`
+- Existing code using `WebScrapingStrategy` will continue to work without modification
+- No changes are required to your existing code

-### 5.3 `screenshot`, `pdf`, and `mhtml`
+### 5.3 `tables`
+
+The `tables` field contains structured data extracted from HTML tables found on the crawled page. Tables are analyzed based on various criteria to determine if they are actual data tables (as opposed to layout tables), including:
+
+- Presence of thead and tbody sections
+- Use of th elements for headers
+- Column consistency
+- Text density
+- And other factors
+
+Tables that score above the threshold (default: 7) are extracted and stored in result.tables.
+
+### Accessing Table data:
+```python
+import asyncio
+from crawl4ai import AsyncWebCrawler, CrawlerRunConfig
+
+async def main():
+    async with AsyncWebCrawler() as crawler:
+        result = await crawler.arun(
+            url="https://www.w3schools.com/html/html_tables.asp",
+            config=CrawlerRunConfig(
+                table_score_threshold=7  # Minimum score for table detection
+            )
+        )
+
+        if result.success and result.tables:
+            print(f"Found {len(result.tables)} tables")
+
+            for i, table in enumerate(result.tables):
+                print(f"\nTable {i+1}:")
+                print(f"Caption: {table.get('caption', 'No caption')}")
+                print(f"Headers: {table['headers']}")
+                print(f"Rows: {len(table['rows'])}")
+
+                # Print first few rows as example
+                for j, row in enumerate(table['rows'][:3]):
+                    print(f"  Row {j+1}: {row}")
+
+if __name__ == "__main__":
+    asyncio.run(main())
+
+```
+
+### Configuring Table Extraction:
+
+You can adjust the sensitivity of the table detection algorithm with:
+
+```python
+config = CrawlerRunConfig(
+    table_score_threshold=5  # Lower value = more tables detected (default: 7)
+)
+```
+
+Each extracted table contains: 
+
+- `headers`: Column header names 
+- `rows`: List of rows, each containing cell values
+- `caption`: Table caption text (if available) 
+- `summary`: Table summary attribute (if specified)
+
+### Table Extraction Tips
+
+- Not all HTML tables are extracted - only those detected as "data tables" vs. layout tables.
+- Tables with inconsistent cell counts, nested tables, or those used purely for layout may be skipped.
+- If you're missing tables, try adjusting the `table_score_threshold` to a lower value (default is 7).
+
+The table detection algorithm scores tables based on features like consistent columns, presence of headers, text density, and more. Tables scoring above the threshold are considered data tables worth extracting.
