This major release adds deep crawling capabilities, memory-adaptive dispatcher,
multiple crawling strategies, Docker deployment, and a new CLI. It also includes
significant improvements to proxy handling, PDF processing, and LLM integration.
BREAKING CHANGES:
- Add memory-adaptive dispatcher as default for arun_many()
- Move max_depth to CrawlerRunConfig
- Replace ScrapingMode enum with strategy pattern
- Update BrowserContext API
- Make model fields optional with defaults
- Remove content_filter parameter from CrawlerRunConfig
- Remove synchronous WebCrawler and old CLI
- Update Docker deployment configuration
- Replace FastFilterChain with FilterChain
- Change license to Apache 2.0 with attribution clause
### New Features:
- **Text-Only Mode**: Added support for text-only crawling by disabling images, JavaScript, GPU, and other non-essential features.
- **Light Mode**: Optimized browser settings to reduce resource usage and improve efficiency during crawling.
- **Dynamic Viewport Adjustment**: Automatically adjusts viewport dimensions based on content size, ensuring accurate rendering and scaling.
- **Full Page Scanning**: Introduced a feature to scroll and capture dynamic content for pages with infinite scroll or lazy-loading elements.
- **Session Management**: Added `create_session` method for creating and managing browser sessions with unique IDs.
### Improvements:
- Unified viewport handling across contexts by dynamically setting dimensions using `self.viewport_width` and `self.viewport_height`.
- Enhanced logging and error handling for viewport adjustments, page scanning, and content evaluation.
- Reduced resource usage with additional browser flags for both `light_mode` and `text_only` configurations.
- Improved handling of cookies, headers, and proxies in session creation.
### Refactoring:
- Removed hardcoded viewport dimensions and replaced them with dynamic configurations.
- Cleaned up unused and commented-out code for better readability and maintainability.
- Introduced defaults for frequently used parameters like `delay_before_return_html`.
### Fixes:
- Resolved potential inconsistencies in viewport handling.
- Improved robustness of content loading and dynamic adjustments to avoid failures and timeouts.
### Docs Update:
- Updated schema usage in `quickstart_async.py` example:
- Changed `OpenAIModelFee.schema()` to `OpenAIModelFee.model_json_schema()` for compatibility.
- Enhanced LLM extraction instruction documentation.
This commit introduces significant enhancements to improve efficiency, flexibility, and reliability of the crawler strategy.
