+### Added
+- **Flexible LLM Provider Configuration** (Docker): 
+  - Support for `LLM_PROVIDER` environment variable to override default provider
+  - Per-request provider override via optional `provider` parameter in API endpoints
+  - Automatic provider validation with clear error messages
+  - Updated Docker documentation and examples
+
+### Changed
+- **WebScrapingStrategy Refactoring**: Simplified content scraping architecture
+  - `WebScrapingStrategy` is now an alias for `LXMLWebScrapingStrategy` for backward compatibility
+  - Removed redundant BeautifulSoup-based implementation (~1000 lines of code)
+  - `LXMLWebScrapingStrategy` now inherits directly from `ContentScrapingStrategy`
+  - All existing code using `WebScrapingStrategy` continues to work without modification
+  - Default scraping strategy remains `LXMLWebScrapingStrategy` for optimal performance
+
 ### Added
 - **AsyncUrlSeeder**: High-performance URL discovery system for intelligent crawling at scale
   - Discover URLs from sitemaps and Common Crawl index

+**Flexible LLM Provider Configuration:**
+
+The Docker setup now supports flexible LLM provider configuration through three methods:
+
+1. **Environment Variable** (Highest Priority): Set `LLM_PROVIDER` to override the default
+   ```bash
+   export LLM_PROVIDER="anthropic/claude-3-opus"
+   # Or in your .llm.env file:
+   # LLM_PROVIDER=anthropic/claude-3-opus
+   ```
+
+2. **API Request Parameter**: Specify provider per request
+   ```json
+   {
+     "url": "https://example.com",
+     "provider": "groq/mixtral-8x7b"
+   }
+   ```
+
+3. **Config File Default**: Falls back to `config.yml` (default: `openai/gpt-4o-mini`)
+
+The system automatically selects the appropriate API key based on the provider.
+
 #### 3. Build and Run with Compose
 
 The `docker-compose.yml` file in the project root provides a simplified approach that automatically handles architecture detection using buildx.

+# 🛠️ Crawl4AI v0.7.1: Minor Cleanup Update
+
+*July 17, 2025 • 2 min read*
+
+---
+
+A small maintenance release that removes unused code and improves documentation.
+
+## 🎯 What's Changed
+
+- **Removed unused StealthConfig** from `crawl4ai/browser_manager.py`
+- **Updated documentation** with better examples and parameter explanations
+- **Fixed virtual scroll configuration** examples in docs
+
+## 🧹 Code Cleanup
+
+Removed unused `StealthConfig` import and configuration that wasn't being used anywhere in the codebase. The project uses its own custom stealth implementation through JavaScript injection instead.
+
+```python
+# Removed unused code:
+from playwright_stealth import StealthConfig
+stealth_config = StealthConfig(...)  # This was never used
+```
+
+## 📖 Documentation Updates
+
+- Fixed adaptive crawling parameter examples
+- Updated session management documentation
+- Corrected virtual scroll configuration examples
+
+## 🚀 Installation
+
+```bash
+pip install crawl4ai==0.7.1
+```
+
+No breaking changes - upgrade directly from v0.7.0.

-## 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

+    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(

+        "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.

+    match_mode=MatchMode.AND  # Must be HTTPS AND contain .doc
+)
+
+# Default config - matches ALL URLs
+default_config = CrawlerRunConfig()  # No url_matcher = matches everything
+```
+
+**UrlMatcher Types:**
+- **None (default)**: When `url_matcher` is None or not set, the config matches ALL URLs
+- **String patterns**: Glob-style patterns like `"*.pdf"`, `"*/api/*"`, `"https://*.example.com/*"`
+- **Functions**: `lambda url: bool` - Custom logic for complex matching
+- **Lists**: Mix strings and functions, combined with `MatchMode.OR` or `MatchMode.AND`
+
+**Important Behavior:**
+- When passing a list of configs to `arun_many()`, URLs are matched against each config's `url_matcher` in order. First match wins!
+- If no config matches a URL and there's no default config (one without `url_matcher`), the URL will fail with "No matching configuration found"
+- Always include a default config as the last item if you want to handle all URLs

+# 🛠️ Crawl4AI v0.7.1: Minor Cleanup Update
+
+*July 17, 2025 • 2 min read*
+
+---
+
+A small maintenance release that removes unused code and improves documentation.
+
+## 🎯 What's Changed
+
+- **Removed unused StealthConfig** from `crawl4ai/browser_manager.py`

+
+## 🧹 Code Cleanup
+
+Removed unused `StealthConfig` import and configuration that wasn't being used anywhere in the codebase. The project uses its own custom stealth implementation through JavaScript injection instead.
+
+```python
+# Removed unused code:
+from playwright_stealth import StealthConfig
+stealth_config = StealthConfig(...)  # This was never used
+```
+
+## 📖 Documentation Updates
+
+- Fixed adaptive crawling parameter examples
+- Updated session management documentation
+- Corrected virtual scroll configuration examples
+
+## 🚀 Installation
+
+```bash
+pip install crawl4ai==0.7.1
+```
+
+No breaking changes - upgrade directly from v0.7.0.

+# 🚀 Crawl4AI v0.7.2: CI/CD & Dependency Optimization Update
+
+*July 25, 2025 • 3 min read*
+
+---
+
+This release introduces automated CI/CD pipelines for seamless releases and optimizes dependencies for a lighter, more efficient package.
+
+## 🎯 What's New
+
+### 🔄 Automated Release Pipeline
+- **GitHub Actions CI/CD**: Automated PyPI and Docker Hub releases on tag push
+- **Multi-platform Docker images**: Support for both AMD64 and ARM64 architectures
+- **Version consistency checks**: Ensures tag, package, and Docker versions align
+- **Automated release notes**: GitHub releases created automatically
+
+### 📦 Dependency Optimization
+- **Moved sentence-transformers to optional dependencies**: Significantly reduces default installation size
+- **Lighter Docker images**: Optimized Dockerfile for faster builds and smaller images
+- **Better dependency management**: Core vs. optional dependencies clearly separated
+
+## 🏗️ CI/CD Pipeline
+
+The new automated release process ensures consistent, reliable releases:
+
+```yaml
+# Trigger releases with a simple tag
+git tag v0.7.2
+git push origin v0.7.2
+
+# Automatically:
+# ✅ Validates version consistency
+# ✅ Builds and publishes to PyPI
+# ✅ Builds multi-platform Docker images
+# ✅ Pushes to Docker Hub with proper tags
+# ✅ Creates GitHub release
+```
+
+## 💾 Lighter Installation
+
+Default installation is now significantly smaller:
+
+```bash
+# Core installation (smaller, faster)
+pip install crawl4ai==0.7.2
+
+# With ML features (includes sentence-transformers)
+pip install crawl4ai[transformer]==0.7.2
+
+# Full installation
+pip install crawl4ai[all]==0.7.2
+```
+
+## 🐳 Docker Improvements
+
+Enhanced Docker support with multi-platform images:
+
+```bash
+# Pull the latest version
+docker pull unclecode/crawl4ai:0.7.2
+docker pull unclecode/crawl4ai:latest
+
+# Available tags:
+# - unclecode/crawl4ai:0.7.2 (specific version)
+# - unclecode/crawl4ai:0.7 (minor version)
+# - unclecode/crawl4ai:0 (major version)
+# - unclecode/crawl4ai:latest
+```
+
+## 🔧 Technical Details
+
+### Dependency Changes
+- `sentence-transformers` moved from required to optional dependencies
+- Reduces default installation by ~500MB
+- No impact on functionality when transformer features aren't needed
+
+### CI/CD Configuration
+- GitHub Actions workflows for automated releases
+- Version validation before publishing
+- Parallel PyPI and Docker Hub deployments
+- Automatic tagging strategy for Docker images
+
+## 🚀 Installation
+
+```bash
+pip install crawl4ai==0.7.2
+```
+
+No breaking changes - direct upgrade from v0.7.0 or v0.7.1.

+Crawl4AI uses `LXMLWebScrapingStrategy` (LXML-based) as the default scraping strategy for HTML content processing. This strategy offers excellent performance, especially for large HTML documents.

 ### 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

+# WebScrapingStrategy Migration Guide
+
+## Overview
+
+Crawl4AI has simplified its content scraping architecture. The BeautifulSoup-based `WebScrapingStrategy` has been deprecated in favor of the faster LXML-based implementation. However, **no action is required** - your existing code will continue to work.
+
+## What Changed?
+
+1. **`WebScrapingStrategy` is now an alias** for `LXMLWebScrapingStrategy`
+2. **The BeautifulSoup implementation has been removed** (~1000 lines of redundant code)
+3. **`LXMLWebScrapingStrategy` inherits directly** from `ContentScrapingStrategy`
+4. **Performance remains optimal** with LXML as the sole implementation
+
+## Backward Compatibility
+
+**Your existing code continues to work without any changes:**
+
+```python
+# This still works perfectly
+from crawl4ai import AsyncWebCrawler, CrawlerRunConfig, WebScrapingStrategy
+
+config = CrawlerRunConfig(
+    scraping_strategy=WebScrapingStrategy()  # Works as before
+)
+```
+
+## Migration Options
+
+You have three options:
+
+### Option 1: Do Nothing (Recommended)
+Your code will continue to work. `WebScrapingStrategy` is permanently aliased to `LXMLWebScrapingStrategy`.
+
+### Option 2: Update Imports (Optional)
+For clarity, you can update your imports:
+
+```python
+# Old (still works)
+from crawl4ai import WebScrapingStrategy
+strategy = WebScrapingStrategy()
+
+# New (more explicit)
+from crawl4ai import LXMLWebScrapingStrategy
+strategy = LXMLWebScrapingStrategy()
+```
+
+### Option 3: Use Default Configuration
+Since `LXMLWebScrapingStrategy` is the default, you can omit the strategy parameter:
+
+```python
+# Simplest approach - uses LXMLWebScrapingStrategy by default
+config = CrawlerRunConfig()
+```
+
+## Type Hints
+
+If you use type hints, both work:
+
+```python
+from crawl4ai import WebScrapingStrategy, LXMLWebScrapingStrategy
+
+def process_with_strategy(strategy: WebScrapingStrategy) -> None:
+    # Works with both WebScrapingStrategy and LXMLWebScrapingStrategy
+    pass
+
+# Both are valid
+process_with_strategy(WebScrapingStrategy())
+process_with_strategy(LXMLWebScrapingStrategy())
+```
+
+## Subclassing
+
+If you've subclassed `WebScrapingStrategy`, it continues to work:
+
+```python
+class MyCustomStrategy(WebScrapingStrategy):
+    def __init__(self):
+        super().__init__()
+        # Your custom code
+```
+
+## Performance Benefits
+
+By consolidating to LXML:
+- **10-20x faster** HTML parsing for large documents
+- **Lower memory usage**
+- **Consistent behavior** across all use cases
+- **Simplified maintenance** and bug fixes
+
+## Summary
+
+This change simplifies Crawl4AI's internals while maintaining 100% backward compatibility. Your existing code continues to work, and you get better performance automatically.
