Breaking changes: None
Adds new target_elements parameter to CrawlerRunConfig that allows more flexible content selection than css_selector. This enables focusing markdown generation and data extraction on specific elements while still processing the entire page for links and media.
Key changes:
- Added target_elements list parameter to CrawlerRunConfig
- Modified WebScrapingStrategy and LXMLWebScrapingStrategy to handle target_elements
- Updated documentation with examples and comparison between css_selector and target_elements
- Fixed table extraction in content_scraping_strategy.py
BREAKING CHANGE: Table extraction logic has been modified to better handle thead/tbody structures
Add new features to enhance browser automation and HTML extraction:
- Add CDP browser launch capability with customizable ports and profiles
- Implement JsonLxmlExtractionStrategy for faster HTML parsing
- Add CLI command 'crwl cdp' for launching standalone CDP browsers
- Support connecting to external CDP browsers via URL
- Optimize selector caching and context-sensitive queries
BREAKING CHANGE: LLMConfig import path changed from crawl4ai.types to crawl4ai
Rename LlmConfig to LLMConfig across the codebase to follow consistent naming conventions.
Update all imports and usages to use the new name.
Update documentation and examples to reflect the change.
BREAKING CHANGE: LlmConfig has been renamed to LLMConfig. Users need to update their imports and usage.

Remove content filter related code and parameters as part of simplifying the crawler configuration. This includes:
- Removing ContentFilter import and related classes
- Removing content_filter parameter from CrawlerRunConfig
- Cleaning up LLMExtractionStrategy constructor parameters
BREAKING CHANGE: Removed content_filter parameter from CrawlerRunConfig. Users should migrate to using extraction strategies for content filtering.
Implements a new proxy rotation system with the following changes:
- Add ProxyRotationStrategy abstract base class
- Add RoundRobinProxyStrategy concrete implementation
- Integrate proxy rotation with AsyncWebCrawler
- Add proxy_rotation_strategy parameter to CrawlerRunConfig
- Add example script demonstrating proxy rotation usage
- Remove deprecated synchronous WebCrawler code
- Clean up rate limiting documentation
BREAKING CHANGE: Removed synchronous WebCrawler support and related rate limiting configurations
Enhanced markdown formatting, fixed list indentation, and improved readability across multiple API documentation files:
- arun.md
- arun_many.md
- async-webcrawler.md
- parameters.md
Changes include:
- Consistent list formatting and indentation
- Better spacing between sections
