 ## ✨ Recent Updates
 
--   **🚀 New Dispatcher System**: Scale to thousands of URLs with intelligent **memory monitoring**, **concurrency control**, and optional **rate limiting**. (See `MemoryAdaptiveDispatcher`, `SemaphoreDispatcher`, `RateLimiter`, `CrawlerMonitor`)
+### Version 0.5.0 Major Release Highlights
--   **⚡ Streaming Mode**: Process results **as they arrive** instead of waiting for an entire batch to complete. (Set `stream=True` in `CrawlerRunConfig`)
--   **🤖 Enhanced LLM Integration**:
-    -   **Automatic schema generation**: Create extraction rules from HTML using OpenAI or Ollama, no manual CSS/XPath needed.
-    -   **LLM-powered Markdown filtering**: Refine your markdown output with a new `LLMContentFilter` that understands content relevance.
-    -   **Ollama Support**: Use open-source or self-hosted models for private or cost-effective extraction.
--   **🏎️ Faster Scraping Option**: New `LXMLWebScrapingStrategy` offers **10-20x speedup** for large, complex pages (experimental).
--   **🤖 robots.txt Compliance**: Respect website rules with `check_robots_txt=True` and efficient local caching.
--   **🔄 Proxy Rotation**: Built-in support for dynamic proxy switching and IP verification, with support for authenticated proxies and session persistence.
--   **➡️ URL Redirection Tracking**: The `redirected_url` field now captures the final destination after any redirects.
--   **🪞 Improved Mirroring**: The `LXMLWebScrapingStrategy` now has much greater fidelity, allowing for almost pixel-perfect mirroring of websites.
--   **📈 Enhanced Monitoring**: Track memory, CPU, and individual crawler status with `CrawlerMonitor`.
--   **📝 Improved Documentation**: More examples, clearer explanations, and updated tutorials.
