…strategy 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
Moves ProxyConfig from configs/ directory into proxy_strategy.py to improve code organization and reduce fragmentation. Updates all imports and type hints to reflect the new location. Key changes: - Moved ProxyConfig class from configs/proxy_config.py to proxy_strategy.py - Updated type hints in async_configs.py to support ProxyConfig - Fixed proxy configuration handling in browser_manager.py - Updated documentation and examples to use new import path BREAKING CHANGE: ProxyConfig import path has changed from crawl4ai.configs to crawl4ai.proxy_strategy
Adds a new 'reverse' parameter to URLPatternFilter that allows inverting the filter's logic. When reverse=True, URLs that would normally match are rejected and vice versa. Also removes unused 'scraped_html' from WebScrapingStrategy output to reduce memory usage. BREAKING CHANGE: WebScrapingStrategy no longer returns 'scraped_html' in its output dictionary
Add comprehensive table detection and extraction functionality to the web scraping system: - Implement intelligent table detection algorithm with scoring system - Add table extraction with support for headers, rows, captions - Update models to include tables in Media class - Add table_score_threshold configuration option - Add documentation and examples for table extraction - Include crypto analysis example demonstrating table usage This change enables users to extract structured data from HTML tables while intelligently filtering out layout tables.
…traction 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
…nagement Implements a comprehensive monitoring and visualization system for tracking web crawler operations in real-time. The system includes: - Terminal-based dashboard with rich UI for displaying task statuses - Memory pressure monitoring and adaptive dispatch control - Queue statistics and performance metrics tracking - Detailed task progress visualization - Stress testing framework for memory management This addition helps operators track crawler performance and manage memory usage more effectively.
Add new preprocess_html_for_schema utility function to better handle HTML cleaning for schema generation. This replaces the previous optimize_html function in the GoogleSearchCrawler and includes smarter attribute handling and pattern detection. Other changes: - Update default provider to gpt-4o - Add DEFAULT_PROVIDER_API_KEY constant - Make LLMConfig creation more flexible with create_llm_config helper - Add new dependencies: zstandard and msgpack This change improves schema generation reliability while reducing noise in the processed HTML.
…rison Add special handling for single URL requests in Docker API to use arun() instead of arun_many() Add new example script demonstrating performance differences between sequential and parallel crawling Update cache mode from aggressive to bypass in examples and tests Remove unused dependencies (zstandard, msgpack) BREAKING CHANGE: Changed default cache_mode from aggressive to bypass in examples
…ultiple URL processing
…er handling Add experimental parameters dictionary to CrawlerRunConfig to support beta features Make CSP nonce headers optional via experimental config Remove default cookie injection Clean up browser context creation code Improve code formatting in API handler BREAKING CHANGE: Default cookie injection has been removed from page initialization
…atures, changes, fixes, and breaking changes
Extend LLMConfig class to support more fine-grained control over LLM behavior by adding: - temperature control - max tokens limit - top_p sampling - frequency and presence penalties - stop sequences - number of completions These parameters allow for better customization of LLM responses.
Implements a persistent browser management system that allows running a single shared browser instance that can be reused across multiple crawler sessions. Key changes include: - Added browser_mode config option with 'builtin', 'dedicated', and 'custom' modes - Implemented builtin browser management in BrowserProfiler - Added CLI commands for managing builtin browser (start, stop, status, restart, view) - Modified browser process handling to support detached processes - Added automatic builtin browser setup during package installation BREAKING CHANGE: The browser_mode config option changes how browser instances are managed
Adds a new browser management system with strategy pattern implementation: - Introduces BrowserManager class with strategy pattern support - Adds PlaywrightBrowserStrategy, CDPBrowserStrategy, and BuiltinBrowserStrategy - Implements BrowserProfileManager for profile management - Adds PagePoolConfig for browser page pooling - Includes comprehensive test suite for all browser strategies BREAKING CHANGE: Browser management has been moved to browser/ module. Direct usage of browser_manager.py and browser_profiler.py is deprecated.
Remove PagePoolConfig in favor of direct page management in browser strategies. Add get_pages() method for efficient parallel page creation. Improve storage state handling and persistence. Add comprehensive parallel crawling tests and performance analysis. BREAKING CHANGE: Removed PagePoolConfig class and related functionality.
…ory support and improved storage state handling
Enhance storage state persistence mechanism in CDP browser strategy by: - Explicitly saving storage state for each browser context - Using proper file path for storage state - Removing unnecessary sleep delay Also includes test improvements: - Simplified test configurations in playwright tests - Temporarily disabled some CDP tests
Implements a new browser strategy that runs Chrome in Docker containers, providing better isolation and cross-platform consistency. Features include: - Connect and launch modes for different container configurations - Persistent storage support for maintaining browser state - Container registry for efficient reuse - Comprehensive test suite for Docker browser functionality This addition allows users to run browser automation workloads in isolated containers, improving security and resource management.
Adds new features to improve user experience and configuration: - Quick JSON extraction with -j flag for direct LLM-based structured data extraction - Global configuration management with 'crwl config' commands - Enhanced LLM extraction with better JSON handling and error management - New user settings for default behaviors (LLM provider, browser settings, etc.) Breaking changes: None
