+<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.

+2. Run a simple web crawl with Python:
+```python
+import asyncio
+from crawl4ai import *
+
+async def main():
+    async with AsyncWebCrawler() as crawler:
+        result = await crawler.arun(
+            url="https://www.nbcnews.com/business",
+        )
+        print(result.markdown)
+
+if __name__ == "__main__":
+    asyncio.run(main())
+```
+
+3. Or use the new command-line interface:
+```bash
+# Basic crawl with markdown output
+crwl https://www.nbcnews.com/business -o markdown
+
+# Deep crawl with BFS strategy, max 10 pages
+crwl https://docs.crawl4ai.com --deep-crawl bfs --max-pages 10
+
+# Use LLM extraction with a specific question
+crwl https://www.example.com/products -q "Extract all product prices"
+```

+
+## 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
+
+The sync version is deprecated and will be removed in future versions. If you need the synchronous version using Selenium:
+
+```bash
+pip install crawl4ai[sync]
+```
+
+---
+
+### Development Installation
+
+For contributors who plan to modify the source code:
+
+```bash
+git clone https://github.com/unclecode/crawl4ai.git
+cd crawl4ai
+pip install -e .                    # Basic installation in editable mode
+```
+
+Install optional features:
+
+```bash
+pip install -e ".[torch]"           # With PyTorch features
+pip install -e ".[transformer]"     # With Transformer features
+pip install -e ".[cosine]"          # With cosine similarity features
+pip install -e ".[sync]"            # With synchronous crawling (Selenium)
+pip install -e ".[all]"             # Install all optional features
+```

+## ✨ 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
+  ))
+  
+  urls = await seeder.discover("https://example.com")

+
+## 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>
 
-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.

+**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 v0.7.3: 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
+- **🧠 Memory Monitoring**: Enhanced memory usage tracking and optimization tools
+- **📊 Enhanced Table Extraction**: Improved table access and DataFrame conversion
+- **💰 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 \

+
+## 🚀 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")
+```
+

+Stealth Mode Example with Crawl4AI

+Key features demonstrated:
+1. Comparing crawling with and without stealth mode
+2. Testing against bot detection sites
+3. Accessing sites that block automated browsers

+## 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

+# 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

+        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:

+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

+
+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

+    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.

+- **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!

-### [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.
-
-## License Change
-
-Crawl4AI v0.5.0 updates the license to Apache 2.0 *with a required attribution clause*.  This means you are free to use, modify, and distribute Crawl4AI (even commercially), but you *must* clearly attribute the project in any public use or distribution.

+*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.

 ### 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 `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.

 *(Keep Deep Crawler Example)*
 
+### LLM Configuration Examples
+
+The Docker API supports dynamic LLM configuration through multiple levels:
+
+#### Temperature Control
+
+Temperature affects the randomness of LLM responses (0.0 = deterministic, 2.0 = very creative):
+
+```python
+import requests
+
+# Low temperature for factual extraction
+response = requests.post(
+    "http://localhost:11235/md",
+    json={
+        "url": "https://example.com",
+        "f": "llm",
+        "q": "Extract all dates and numbers from this page",
+        "temperature": 0.2  # Very focused, deterministic
+    }
+)
+
+# High temperature for creative tasks
+response = requests.post(
+    "http://localhost:11235/md",
+    json={
+        "url": "https://example.com", 
+        "f": "llm",
+        "q": "Write a creative summary of this content",
+        "temperature": 1.2  # More creative, varied responses
+    }
+)
+```
+
+#### Custom API Endpoints
+
+Use custom base URLs for proxy servers or alternative API endpoints:
+
+```python
+
+# Using a local LLM server
+response = requests.post(
+    "http://localhost:11235/md",
+    json={
+        "url": "https://example.com",
+        "f": "llm",
+        "q": "Extract key information",
+        "provider": "ollama/llama2",
+        "base_url": "http://localhost:11434/v1"
+    }
+)
+```
+
+#### Dynamic Provider Selection
+
+Switch between providers based on task requirements:
+
+```python
+async def smart_extraction(url: str, content_type: str):
+    """Select provider and temperature based on content type"""
+    
+    configs = {
+        "technical": {
+            "provider": "openai/gpt-4",
+            "temperature": 0.3,
+            "query": "Extract technical specifications and code examples"
+        },
+        "creative": {
+            "provider": "anthropic/claude-3-opus",
+            "temperature": 0.9,
+            "query": "Create an engaging narrative summary"
+        },

+        }
+    }

+    config = configs.get(content_type, configs["quick"])
+    
+    response = await httpx.post(
+        "http://localhost:11235/md",
+        json={
+            "url": url,

+# Table Extraction Strategies
+
+## Overview
+
+**New in v0.7.3+**: Table extraction now follows the **Strategy Design Pattern**, providing unprecedented flexibility and power for handling different table structures. Don't worry - **your existing code still works!** We maintain full backward compatibility while offering new capabilities.
+
+### What's Changed?
+- **Architecture**: Table extraction now uses pluggable strategies
+- **Backward Compatible**: Your existing code with `table_score_threshold` continues to work
+- **More Power**: Choose from multiple strategies or create your own
+- **Same Default Behavior**: By default, uses `DefaultTableExtraction` (same as before)
+
+### Key Points
+✅ **Old code still works** - No breaking changes  
+✅ **Same default behavior** - Uses the proven extraction algorithm  
+✅ **New capabilities** - Add LLM extraction or custom strategies when needed  
+✅ **Strategy pattern** - Clean, extensible architecture
+
+## Quick Start
+
+### The Simplest Way (Works Like Before)
+
+If you're already using Crawl4AI, nothing changes:
+
+```python
+import asyncio
+from crawl4ai import AsyncWebCrawler, CrawlerRunConfig
+
+async def extract_tables():
+    async with AsyncWebCrawler() as crawler:
+        # This works exactly like before - uses DefaultTableExtraction internally
+        result = await crawler.arun("https://example.com/data")
+        
+        # Tables are automatically extracted and available in result.tables
+        for table in result.tables:
+            print(f"Table with {len(table['rows'])} rows and {len(table['headers'])} columns")
+            print(f"Headers: {table['headers']}")
+            print(f"First row: {table['rows'][0] if table['rows'] else 'No data'}")
+
+asyncio.run(extract_tables())
+```
+
+### Using the Old Configuration (Still Supported)
+
+Your existing code with `table_score_threshold` continues to work:
+
+```python
+# This old approach STILL WORKS - we maintain backward compatibility
+config = CrawlerRunConfig(
+    table_score_threshold=7  # Internally creates DefaultTableExtraction(table_score_threshold=7)
+)
+result = await crawler.arun(url, config)
+```
+
+## Table Extraction Strategies
+
+### Understanding the Strategy Pattern
+
+The strategy pattern allows you to choose different table extraction algorithms at runtime. Think of it as having different tools in a toolbox - you pick the right one for the job:
+
+- **No explicit strategy?** → Uses `DefaultTableExtraction` automatically (same as v0.7.2 and earlier)
+- **Need complex table handling?** → Choose `LLMTableExtraction` (costs money, use sparingly)
+- **Want to disable tables?** → Use `NoTableExtraction`
+- **Have special requirements?** → Create a custom strategy
+
+### Available Strategies
+
+| Strategy | Description | Use Case | Cost | When to Use |
+|----------|-------------|----------|------|-------------|
+| `DefaultTableExtraction` | **RECOMMENDED**: Same algorithm as before v0.7.3 | General purpose (default) | Free | **Use this first - handles 95% of cases** |
+| `LLMTableExtraction` | AI-powered extraction for complex tables | Tables with complex rowspan/colspan | **$$$ Per API call** | Only when DefaultTableExtraction fails |
+| `NoTableExtraction` | Disables table extraction | When tables aren't needed | Free | For text-only extraction |
+| Custom strategies | User-defined extraction logic | Specialized requirements | Free | Domain-specific needs |
+
+> **⚠️ CRITICAL COST WARNING for LLMTableExtraction**: 
+> 
+> **DO NOT USE `LLMTableExtraction` UNLESS ABSOLUTELY NECESSARY!**
+> 
+> - **Always try `DefaultTableExtraction` first** - It's free and handles most tables perfectly
+> - LLM extraction **costs money** with every API call
+> - For large tables (100+ rows), LLM extraction can be **very slow**
+> - **For large tables**: If you must use LLM, choose fast providers:
+>   - ✅ **Groq** (fastest inference)
+>   - ✅ **Cerebras** (optimized for speed)
+>   - ⚠️ Avoid: OpenAI, Anthropic for large tables (slower)
+> 
+> **🚧 WORK IN PROGRESS**: 
+> We are actively developing an **advanced non-LLM algorithm** that will handle complex table structures (rowspan, colspan, nested tables) for **FREE**. This will replace the need for costly LLM extraction in most cases. Coming soon!
+
+### DefaultTableExtraction
+
+The default strategy uses a sophisticated scoring system to identify data tables:
+
+```python
+from crawl4ai import DefaultTableExtraction, CrawlerRunConfig
+
+# Customize the default extraction
+table_strategy = DefaultTableExtraction(
+    table_score_threshold=7,  # Scoring threshold (default: 7)
+    min_rows=2,               # Minimum rows required
+    min_cols=2,               # Minimum columns required
+    verbose=True              # Enable detailed logging
+)
+
+config = CrawlerRunConfig(
+    table_extraction=table_strategy
+)
+```
+
+#### Scoring System
+
+The scoring system evaluates multiple factors:
+
+| Factor | Score Impact | Description |
+|--------|--------------|-------------|
+| Has `<thead>` | +2 | Semantic table structure |
+| Has `<tbody>` | +1 | Organized table body |
+| Has `<th>` elements | +2 | Header cells present |
+| Headers in correct position | +1 | Proper semantic structure |
+| Consistent column count | +2 | Regular data structure |
+| Has caption | +2 | Descriptive caption |
+| Has summary | +1 | Summary attribute |
+| High text density | +2 to +3 | Content-rich cells |
+| Data attributes | +0.5 each | Data-* attributes |
+| Nested tables | -3 | Often indicates layout |
+| Role="presentation" | -3 | Explicitly non-data |
+| Too few rows | -2 | Insufficient data |
+
+### LLMTableExtraction (Use Sparingly!)
+
+**⚠️ WARNING**: Only use this when `DefaultTableExtraction` fails with complex tables!
+
+LLMTableExtraction uses AI to understand complex table structures that traditional parsers struggle with. It automatically handles large tables through intelligent chunking and parallel processing:
+
+```python
+from crawl4ai import LLMTableExtraction, LLMConfig, CrawlerRunConfig
+
+# Configure LLM (costs money per call!)
+llm_config = LLMConfig(
+    provider="groq/llama-3.3-70b-versatile",  # Fast provider for large tables
+    api_token="your_api_key",
+    temperature=0.1
+)
+
+# Create LLM extraction strategy with smart chunking
+table_strategy = LLMTableExtraction(
+    llm_config=llm_config,
+    max_tries=3,                      # Retry up to 3 times if extraction fails
+    css_selector="table",             # Optional: focus on specific tables
+    enable_chunking=True,             # Automatically chunk large tables (default: True)
+    chunk_token_threshold=3000,       # Split tables larger than this (default: 3000 tokens)
+    min_rows_per_chunk=10,            # Minimum rows per chunk (default: 10)
+    max_parallel_chunks=5,            # Process up to 5 chunks in parallel (default: 5)
+    verbose=True
+)
+
+config = CrawlerRunConfig(
+    table_extraction=table_strategy
+)
+
+result = await crawler.arun(url, config)
+```
+
+#### When to Use LLMTableExtraction
+
+✅ **Use ONLY when**:
+- Tables have complex merged cells (rowspan/colspan) that break DefaultTableExtraction
+- Nested tables that need semantic understanding
+- Tables with irregular structures
+- You've tried DefaultTableExtraction and it failed
+
+❌ **Never use when**:
+- DefaultTableExtraction works (99% of cases)
+- Tables are simple or well-structured
+- You're processing many pages (costs add up!)
+- Tables have 100+ rows (very slow)
+
+#### How Smart Chunking Works
+
+LLMTableExtraction automatically handles large tables through intelligent chunking:
+
+1. **Automatic Detection**: Tables exceeding the token threshold are automatically split
+2. **Smart Splitting**: Chunks are created at row boundaries, preserving table structure
+3. **Header Preservation**: Each chunk includes the original headers for context
+4. **Parallel Processing**: Multiple chunks are processed simultaneously for speed
+5. **Intelligent Merging**: Results are merged back into a single, complete table
+
+**Chunking Parameters**:
+- `enable_chunking` (default: `True`): Automatically handle large tables
+- `chunk_token_threshold` (default: `3000`): When to split tables
+- `min_rows_per_chunk` (default: `10`): Ensures meaningful chunk sizes
+- `max_parallel_chunks` (default: `5`): Concurrent processing for speed
+
+The chunking is completely transparent - you get the same output format whether the table was processed in one piece or multiple chunks.
+
+#### Performance Optimization for LLMTableExtraction
+
+**Provider Recommendations by Table Size**:
+
+| Table Size | Recommended Providers | Why |
+|------------|----------------------|-----|
+| Small (<50 rows) | Any provider | Fast enough |
+| Medium (50-200 rows) | Groq, Cerebras | Optimized inference |
+| Large (200+ rows) | **Groq** (best), Cerebras | Fastest inference + automatic chunking |
+| Very Large (500+ rows) | Groq with chunking | Parallel processing keeps it fast |
+
+### NoTableExtraction
+
+Disable table extraction for better performance when tables aren't needed:
+
+```python
+from crawl4ai import NoTableExtraction, CrawlerRunConfig
+
+config = CrawlerRunConfig(
+    table_extraction=NoTableExtraction()
+)
+
+# Tables won't be extracted, improving performance
+result = await crawler.arun(url, config)
+assert len(result.tables) == 0
+```
+
+## Extracted Table Structure
+
+Each extracted table contains:
+
+```python
+{
+    "headers": ["Column 1", "Column 2", ...],  # Column headers
+    "rows": [                                   # Data rows
+        ["Row 1 Col 1", "Row 1 Col 2", ...],

+        "class": "financial-data"               # Table class if present
+    }
+}
+```
+
+## Configuration Options
+
+### Basic Configuration
+
+```python
+config = CrawlerRunConfig(
+    # Table extraction settings
+    table_score_threshold=7,      # Default threshold (backward compatible)
+    table_extraction=strategy,     # Optional: custom strategy
+    
+    # Filter what to process
+    css_selector="main",          # Focus on specific area
+    excluded_tags=["nav", "aside"] # Exclude page sections
+)
+```
+
+### Advanced Configuration
+
+```python
+from crawl4ai import DefaultTableExtraction, CrawlerRunConfig
+
+# Fine-tuned extraction
+strategy = DefaultTableExtraction(
+    table_score_threshold=5,      # Lower = more permissive
+    min_rows=3,                   # Require at least 3 rows
+    min_cols=2,                   # Require at least 2 columns
+    verbose=True                  # Detailed logging
+)
+
+config = CrawlerRunConfig(
+    table_extraction=strategy,
+    css_selector="article.content", # Target specific content
+    exclude_domains=["ads.com"],   # Exclude ad domains
+    cache_mode=CacheMode.BYPASS    # Fresh extraction
+)
+```
+
+## Working with Extracted Tables
+
+### Convert to Pandas DataFrame
+
+```python
+import pandas as pd
+
+async def tables_to_dataframes(url):
+    async with AsyncWebCrawler() as crawler:
+        result = await crawler.arun(url)
+        
+        dataframes = []
+        for table_data in result.tables:
+            # Create DataFrame
+            if table_data['headers']:
+                df = pd.DataFrame(
+                    table_data['rows'],
+                    columns=table_data['headers']
+                )
+            else:
+                df = pd.DataFrame(table_data['rows'])
+            
+            # Add metadata as DataFrame attributes
+            df.attrs['caption'] = table_data.get('caption', '')
+            df.attrs['metadata'] = table_data.get('metadata', {})
+            
+            dataframes.append(df)
+        
+        return dataframes
+```
+
+### Filter Tables by Criteria
+
+```python
+async def extract_large_tables(url):
+    async with AsyncWebCrawler() as crawler:
+        # Configure minimum size requirements
+        strategy = DefaultTableExtraction(
+            min_rows=10,
+            min_cols=3,
+            table_score_threshold=6
+        )
+        
+        config = CrawlerRunConfig(
+            table_extraction=strategy
+        )
+        
+        result = await crawler.arun(url, config)
+        
+        # Further filter results
+        large_tables = [
+            table for table in result.tables
+            if table['metadata']['row_count'] > 10
+            and table['metadata']['column_count'] > 3
+        ]
+        
+        return large_tables
+```
+
+### Export Tables to Different Formats
+
+```python
+import json
+import csv
+
+async def export_tables(url):
+    async with AsyncWebCrawler() as crawler:
+        result = await crawler.arun(url)
+        
+        for i, table in enumerate(result.tables):
+            # Export as JSON
+            with open(f'table_{i}.json', 'w') as f:
+                json.dump(table, f, indent=2)
+            
+            # Export as CSV
+            with open(f'table_{i}.csv', 'w', newline='') as f:
+                writer = csv.writer(f)
+                if table['headers']:
+                    writer.writerow(table['headers'])
+                writer.writerows(table['rows'])
+            
+            # Export as Markdown
+            with open(f'table_{i}.md', 'w') as f:
+                # Write headers
+                if table['headers']:
+                    f.write('| ' + ' | '.join(table['headers']) + ' |\n')
+                    f.write('|' + '---|' * len(table['headers']) + '\n')
+                
+                # Write rows
+                for row in table['rows']:
+                    f.write('| ' + ' | '.join(str(cell) for cell in row) + ' |\n')
+```
+
+## Creating Custom Strategies
+
+Extend `TableExtractionStrategy` to create custom extraction logic:
+
+### Example: Financial Table Extractor
+
+```python
+from crawl4ai import TableExtractionStrategy
+from typing import List, Dict, Any
+import re
+
+class FinancialTableExtractor(TableExtractionStrategy):
+    """Extract tables containing financial data."""
+    
+    def __init__(self, currency_symbols=None, require_numbers=True, **kwargs):
+        super().__init__(**kwargs)
+        self.currency_symbols = currency_symbols or ['$', '€', '£', '¥']
+        self.require_numbers = require_numbers
+        self.number_pattern = re.compile(r'\d+[,.]?\d*')
+    
+    def extract_tables(self, element, **kwargs):
+        tables_data = []
+        
+        for table in element.xpath(".//table"):
+            # Check if table contains financial indicators
+            table_text = ''.join(table.itertext())
+            
+            # Must contain currency symbols
+            has_currency = any(sym in table_text for sym in self.currency_symbols)
+            if not has_currency:
+                continue
+            
+            # Must contain numbers if required
+            if self.require_numbers:
+                numbers = self.number_pattern.findall(table_text)
+                if len(numbers) < 3:  # Arbitrary minimum
+                    continue
+            
+            # Extract the table data
+            table_data = self._extract_financial_data(table)
+            if table_data:

+                # Clean currency formatting
+                text = re.sub(r'[$€£¥,]', '', text)
+                row.append(text)
+            if row:
+                rows.append(row)

+                "column_count": len(headers) or len(rows[0]) if rows else 0
+            }
+        }
+    
+    def _get_caption(self, table):
+        caption = table.xpath(".//caption/text()")
+        return caption[0].strip() if caption else ""
+
+# Usage
+strategy = FinancialTableExtractor(
+    currency_symbols=['$', 'EUR'],
+    require_numbers=True
+)
+
+config = CrawlerRunConfig(
+    table_extraction=strategy
+)
+```
+
+### Example: Specific Table Extractor
+
+```python
+class SpecificTableExtractor(TableExtractionStrategy):

+        
+        return tables_data
+```
+
+## Combining with Other Strategies
+
+Table extraction works seamlessly with other Crawl4AI strategies:
+
+```python
+from crawl4ai import (
+    AsyncWebCrawler,
+    CrawlerRunConfig,
+    DefaultTableExtraction,
+    LLMExtractionStrategy,
+    JsonCssExtractionStrategy
+)
+
+async def combined_extraction(url):
+    async with AsyncWebCrawler() as crawler:
+        config = CrawlerRunConfig(
+            # Table extraction
+            table_extraction=DefaultTableExtraction(
+                table_score_threshold=6,
+                min_rows=2
+            ),
+            
+            # CSS-based extraction for specific elements
+            extraction_strategy=JsonCssExtractionStrategy({
+                "title": "h1",
+                "summary": "p.summary",
+                "date": "time"
+            }),
+            
+            # Focus on main content
+            css_selector="main.content"
+        )
+        
+        result = await crawler.arun(url, config)
+        
+        # Access different extraction results
+        tables = result.tables  # Table data
+        structured = json.loads(result.extracted_content)  # CSS extraction
+        
+        return {
+            "tables": tables,
+            "structured_data": structured,
+            "markdown": result.markdown
+        }
+```
+
+## Performance Considerations
+
+### Optimization Tips
+
+1. **Disable when not needed**: Use `NoTableExtraction` if tables aren't required
+2. **Target specific areas**: Use `css_selector` to limit processing scope
+3. **Set minimum thresholds**: Filter out small/irrelevant tables early
+4. **Cache results**: Use appropriate cache modes for repeated extractions
+
+```python
+# Optimized configuration for large pages
+config = CrawlerRunConfig(
+    # Only process main content area
+    css_selector="article.main-content",
+    
+    # Exclude navigation and sidebars
+    excluded_tags=["nav", "aside", "footer"],
+    
+    # Higher threshold for stricter filtering
+    table_extraction=DefaultTableExtraction(
+        table_score_threshold=8,
+        min_rows=5,
+        min_cols=3
+    ),
+    
+    # Enable caching for repeated access
+    cache_mode=CacheMode.ENABLED
+)
+```
+
+## Migration Guide
+
+### Important: Your Code Still Works!
+
+**No changes required!** The transition to the strategy pattern is **fully backward compatible**.
+
+### How It Works Internally
+
+#### v0.7.2 and Earlier
+```python
+# Old way - directly passing table_score_threshold
+config = CrawlerRunConfig(
+    table_score_threshold=7
+)
+# Internally: No strategy pattern, direct implementation
+```
+
+#### v0.7.3+ (Current)
+```python
+# Old way STILL WORKS - we handle it internally
+config = CrawlerRunConfig(
+    table_score_threshold=7
+)
+# Internally: Automatically creates DefaultTableExtraction(table_score_threshold=7)
+```
+
+### Taking Advantage of New Features
+
+While your old code works, you can now use the strategy pattern for more control:
+
+```python
+# Option 1: Keep using the old way (perfectly fine!)
+config = CrawlerRunConfig(
+    table_score_threshold=7  # Still supported
+)
+
+# Option 2: Use the new strategy pattern (more flexibility)
+from crawl4ai import DefaultTableExtraction
+
+strategy = DefaultTableExtraction(
+    table_score_threshold=7,
+    min_rows=2,  # New capability!
+    min_cols=2   # New capability!
+)
+
+config = CrawlerRunConfig(
+    table_extraction=strategy
+)
+
+# Option 3: Use advanced strategies when needed
+from crawl4ai import LLMTableExtraction, LLMConfig
+
+# Only for complex tables that DefaultTableExtraction can't handle
+# Automatically handles large tables with smart chunking
+llm_strategy = LLMTableExtraction(
+    llm_config=LLMConfig(
+        provider="groq/llama-3.3-70b-versatile",
+        api_token="your_key"
+    ),
+    max_tries=3,
+    enable_chunking=True,  # Automatically chunk large tables
+    chunk_token_threshold=3000,  # Chunk when exceeding 3000 tokens
+    max_parallel_chunks=5  # Process up to 5 chunks in parallel
+)
+
+config = CrawlerRunConfig(
+    table_extraction=llm_strategy  # Advanced extraction with automatic chunking
+)
+```
+
+### Summary
+
+- ✅ **No breaking changes** - Old code works as-is
+- ✅ **Same defaults** - DefaultTableExtraction is automatically used
+- ✅ **Gradual adoption** - Use new features when you need them
+- ✅ **Full compatibility** - result.tables structure unchanged
+
+## Best Practices
+
+### 1. Choose the Right Strategy (Cost-Conscious Approach)
+
+**Decision Flow**:
+```
+1. Do you need tables? 
+   → No: Use NoTableExtraction
+   → Yes: Continue to #2
+
+2. Try DefaultTableExtraction first (FREE)
+   → Works? Done! ✅
+   → Fails? Continue to #3
+
+3. Is the table critical and complex?
+   → No: Accept DefaultTableExtraction results
+   → Yes: Continue to #4
+
+4. Use LLMTableExtraction (COSTS MONEY)
+   → Small table (<50 rows): Any LLM provider
+   → Large table (50+ rows): Use Groq or Cerebras
+   → Very large (500+ rows): Reconsider - maybe chunk the page
+```
+
+**Strategy Selection Guide**:
+- **DefaultTableExtraction**: Use for 99% of cases - it's free and effective
+- **LLMTableExtraction**: Only for complex tables with merged cells that break DefaultTableExtraction
+- **NoTableExtraction**: When you only need text/markdown content
+- **Custom Strategy**: For specialized requirements (financial, scientific, etc.)
+
+### 2. Validate Extracted Data
+
+```python
+def validate_table(table):
+    """Validate table data quality."""
+    # Check structure
+    if not table.get('rows'):
+        return False
+    
+    # Check consistency
+    if table.get('headers'):
+        expected_cols = len(table['headers'])
+        for row in table['rows']:
+            if len(row) != expected_cols:
+                return False
+    
+    # Check minimum content
+    total_cells = sum(len(row) for row in table['rows'])
+    non_empty = sum(1 for row in table['rows'] 
+                    for cell in row if cell.strip())
+    
+    if non_empty / total_cells < 0.5:  # Less than 50% non-empty
+        return False
+    
+    return True
+
+# Filter valid tables
+valid_tables = [t for t in result.tables if validate_table(t)]
+```
+
+### 3. Handle Edge Cases
+
+```python
+async def robust_table_extraction(url):
+    """Extract tables with error handling."""
+    async with AsyncWebCrawler() as crawler:
+        try:
+            config = CrawlerRunConfig(
+                table_extraction=DefaultTableExtraction(
+                    table_score_threshold=6,
+                    verbose=True
+                )
+            )
+            
+            result = await crawler.arun(url, config)
+            
+            if not result.success:
+                print(f"Crawl failed: {result.error}")
+                return []
+            
+            # Process tables safely
+            processed_tables = []
+            for table in result.tables:
+                try:
+                    # Validate and process
+                    if validate_table(table):
+                        processed_tables.append(table)
+                except Exception as e:
+                    print(f"Error processing table: {e}")
+                    continue
+            
+            return processed_tables
+            
+        except Exception as e:
+            print(f"Extraction error: {e}")
+            return []
+```
+
+## Troubleshooting
+
+### Common Issues and Solutions
+
+| Issue | Cause | Solution |
+|-------|-------|----------|
+| No tables extracted | Score too high | Lower `table_score_threshold` |
+| Layout tables included | Score too low | Increase `table_score_threshold` |
+| Missing tables | CSS selector too specific | Broaden or remove `css_selector` |
+| Incomplete data | Complex table structure | Create custom strategy |
+| Performance issues | Processing entire page | Use `css_selector` to limit scope |
+
+### Debug Logging
+
+Enable verbose logging to understand extraction decisions:
+
+```python
+import logging
+
+# Configure logging
+logging.basicConfig(level=logging.DEBUG)
+
+# Enable verbose mode in strategy
+strategy = DefaultTableExtraction(
+    table_score_threshold=7,
+    verbose=True  # Detailed extraction logs
+)
+
+config = CrawlerRunConfig(
+    table_extraction=strategy,
+    verbose=True  # General crawler logs
+)
+```

+# Migration Guide: Table Extraction v0.7.3
+
+## Overview
+
+Version 0.7.3 introduces the **Table Extraction Strategy Pattern**, providing a more flexible and extensible approach to table extraction while maintaining full backward compatibility.
+
+## What's New
+
+### Strategy Pattern Implementation
+
+Table extraction now follows the same strategy pattern used throughout Crawl4AI:
+
+- **Consistent Architecture**: Aligns with extraction, chunking, and markdown strategies
+- **Extensibility**: Easy to create custom table extraction strategies
+- **Better Separation**: Table logic moved from content scraping to dedicated module
+- **Full Control**: Fine-grained control over table detection and extraction
+
+### New Classes
+
+```python
+from crawl4ai import (
+    TableExtractionStrategy,    # Abstract base class
+    DefaultTableExtraction,      # Current implementation (default)
+    NoTableExtraction           # Explicitly disable extraction
+)
+```
+
+## Backward Compatibility
+
+**✅ All existing code continues to work without changes.**
+
+### No Changes Required
+
+If your code looks like this, it will continue to work:
+
+```python
+# This still works exactly the same
+config = CrawlerRunConfig(
+    table_score_threshold=7
+)
+result = await crawler.arun(url, config)
+tables = result.tables  # Same structure, same data
+```
+
+### What Happens Behind the Scenes
+
+When you don't specify a `table_extraction` strategy:
+
+1. `CrawlerRunConfig` automatically creates `DefaultTableExtraction`
+2. It uses your `table_score_threshold` parameter
+3. Tables are extracted exactly as before
+4. Results appear in `result.tables` with the same structure
+
+## New Capabilities
+
+### 1. Explicit Strategy Configuration
+
+You can now explicitly configure table extraction:
+
+```python
+# New: Explicit control
+strategy = DefaultTableExtraction(
+    table_score_threshold=7,
+    min_rows=2,              # New: minimum row filter
+    min_cols=2,              # New: minimum column filter
+    verbose=True             # New: detailed logging
+)
+
+config = CrawlerRunConfig(
+    table_extraction=strategy
+)
+```
+
+### 2. Disable Table Extraction
+
+Improve performance when tables aren't needed:
+
+```python
+# New: Skip table extraction entirely
+config = CrawlerRunConfig(
+    table_extraction=NoTableExtraction()
+)
+# No CPU cycles spent on table detection/extraction
+```
+
+### 3. Custom Extraction Strategies
+
+Create specialized extractors:
+
+```python
+class MyTableExtractor(TableExtractionStrategy):
+    def extract_tables(self, element, **kwargs):
+        # Custom extraction logic
+        return custom_tables
+
+config = CrawlerRunConfig(
+    table_extraction=MyTableExtractor()
+)
+```
+
+## Migration Scenarios
+
+### Scenario 1: Basic Usage (No Changes Needed)
+
+**Before (v0.7.2):**
+```python
+config = CrawlerRunConfig()
+result = await crawler.arun(url, config)
+for table in result.tables:
+    print(table['headers'])
+```
+
+**After (v0.7.3):**
+```python
+# Exactly the same - no changes required
+config = CrawlerRunConfig()
+result = await crawler.arun(url, config)
+for table in result.tables:
+    print(table['headers'])
+```
+
+### Scenario 2: Custom Threshold (No Changes Needed)
+
+**Before (v0.7.2):**
+```python
+config = CrawlerRunConfig(
+    table_score_threshold=5
+)
+```
+
+**After (v0.7.3):**
+```python
+# Still works the same
+config = CrawlerRunConfig(
+    table_score_threshold=5
+)
+
+# Or use new explicit approach for more control
+strategy = DefaultTableExtraction(
+    table_score_threshold=5,
+    min_rows=2  # Additional filtering
+)
+config = CrawlerRunConfig(
+    table_extraction=strategy
+)
+```
+
+### Scenario 3: Advanced Filtering (New Feature)
+
+**Before (v0.7.2):**
+```python
+# Had to filter after extraction
+config = CrawlerRunConfig(
+    table_score_threshold=5
+)
+result = await crawler.arun(url, config)
+
+# Manual filtering
+large_tables = [
+    t for t in result.tables 
+    if len(t['rows']) >= 5 and len(t['headers']) >= 3
+]
+```
+
+**After (v0.7.3):**
+```python
+# Filter during extraction (more efficient)
+strategy = DefaultTableExtraction(
+    table_score_threshold=5,
+    min_rows=5,
+    min_cols=3
+)
+config = CrawlerRunConfig(
+    table_extraction=strategy
+)
+result = await crawler.arun(url, config)
+# result.tables already filtered
+```
+
+## Code Organization Changes
+
+### Module Structure
+
+**Before (v0.7.2):**
+```
+crawl4ai/
+  content_scraping_strategy.py
+    - LXMLWebScrapingStrategy
+      - is_data_table()      # Table detection
+      - extract_table_data() # Table extraction
+```
+
+**After (v0.7.3):**
+```
+crawl4ai/
+  content_scraping_strategy.py
+    - LXMLWebScrapingStrategy
+      # Table methods removed, uses strategy
+  
+  table_extraction.py (NEW)
+    - TableExtractionStrategy    # Base class
+    - DefaultTableExtraction      # Moved logic here
+    - NoTableExtraction          # New option
+```
+
+### Import Changes
+
+**New imports available (optional):**
+```python
+# These are now available but not required for existing code
+from crawl4ai import (
+    TableExtractionStrategy,
+    DefaultTableExtraction,
+    NoTableExtraction
+)
+```
+
+## Performance Implications
+
+### No Performance Impact
+
+For existing code, performance remains identical:
+- Same extraction logic
+- Same scoring algorithm
+- Same processing time
+
+### Performance Improvements Available
+
+New options for better performance:
+
+```python
+# Skip tables entirely (faster)
+config = CrawlerRunConfig(
+    table_extraction=NoTableExtraction()
+)
+
+# Process only specific areas (faster)
+config = CrawlerRunConfig(
+    css_selector="main.content",
+    table_extraction=DefaultTableExtraction(
+        min_rows=5,  # Skip small tables
+        min_cols=3
+    )
+)
+```
+
+## Testing Your Migration
+
+### Verification Script
+
+Run this to verify your extraction still works:
+
+```python
+import asyncio
+from crawl4ai import AsyncWebCrawler, CrawlerRunConfig
+
+async def verify_extraction():
+    url = "your_url_here"
+    
+    async with AsyncWebCrawler() as crawler:
+        # Test 1: Old approach
+        config_old = CrawlerRunConfig(
+            table_score_threshold=7
+        )
+        result_old = await crawler.arun(url, config_old)
+        
+        # Test 2: New explicit approach
+        from crawl4ai import DefaultTableExtraction
+        config_new = CrawlerRunConfig(
+            table_extraction=DefaultTableExtraction(
+                table_score_threshold=7
+            )
+        )
+        result_new = await crawler.arun(url, config_new)
+        
+        # Compare results
+        assert len(result_old.tables) == len(result_new.tables)
+        print(f"✓ Both approaches extracted {len(result_old.tables)} tables")
+        
+        # Verify structure
+        for old, new in zip(result_old.tables, result_new.tables):
+            assert old['headers'] == new['headers']
+            assert old['rows'] == new['rows']
+        
+        print("✓ Table content identical")
+
+asyncio.run(verify_extraction())
+```
+
+## Deprecation Notes
+
+### No Deprecations
+
+- All existing parameters continue to work
+- `table_score_threshold` in `CrawlerRunConfig` is still supported
+- No breaking changes
+
+### Internal Changes (Transparent to Users)
+
+- `LXMLWebScrapingStrategy.is_data_table()` - Moved to `DefaultTableExtraction`
+- `LXMLWebScrapingStrategy.extract_table_data()` - Moved to `DefaultTableExtraction`
+
+These methods were internal and not part of the public API.
+
+## Benefits of Upgrading
+
+While not required, using the new pattern provides:
+
+1. **Better Control**: Filter tables during extraction, not after
+2. **Performance Options**: Skip extraction when not needed
+3. **Extensibility**: Create custom extractors for specific needs
+4. **Consistency**: Same pattern as other Crawl4AI strategies
+5. **Future-Proof**: Ready for upcoming advanced strategies
+
+## Troubleshooting
+
+### Issue: Different Number of Tables
+
+**Cause**: Threshold or filtering differences
+
+**Solution**: 
+```python
+# Ensure same threshold
+strategy = DefaultTableExtraction(
+    table_score_threshold=7,  # Match your old setting
+    min_rows=0,               # No filtering (default)
+    min_cols=0                # No filtering (default)
+)
+```
+
+### Issue: Import Errors
+
+**Cause**: Using new classes without importing
+
+**Solution**:
+```python
+# Add imports if using new features
+from crawl4ai import (
+    DefaultTableExtraction,
+    NoTableExtraction,
+    TableExtractionStrategy
+)
+```
+
+### Issue: Custom Strategy Not Working
+
+**Cause**: Incorrect method signature
+
+**Solution**:
+```python
+class CustomExtractor(TableExtractionStrategy):
+    def extract_tables(self, element, **kwargs):  # Correct signature
+        # Not: extract_tables(self, html)
+        # Not: extract(self, element)
+        return tables_list
+```
+
+## Getting Help
+
+If you encounter issues:
+
+1. Check your `table_score_threshold` matches previous settings
+2. Verify imports if using new classes
+3. Enable verbose logging: `DefaultTableExtraction(verbose=True)`
+4. Review the [Table Extraction Documentation](../core/table_extraction.md)
+5. Check [examples](../examples/table_extraction_example.py)
+
+## Summary
+
+- ✅ **Full backward compatibility** - No code changes required
+- ✅ **Same results** - Identical extraction behavior by default
+- ✅ **New options** - Additional control when needed
+- ✅ **Better architecture** - Consistent with Crawl4AI patterns
+- ✅ **Ready for future** - Foundation for advanced strategies
+
+The migration to v0.7.3 is seamless with no required changes while providing new capabilities for those who need them.

+# 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.
