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
Add DefaultMarkdownGenerator integration and automatic content filtering for markdown output formats. When using 'markdown-fit' or 'md-fit' output formats, automatically apply PruningContentFilter with default settings if no filter config is provided.
This change improves the user experience by providing sensible defaults for markdown generation while maintaining the ability to customize filtering behavior.
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
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.
Make 'crawl' the default command when no command is specified.
This improves user experience by allowing direct URL input without
explicitly specifying the 'crawl' command.
Also removes unnecessary blank lines in example code for better readability.
Adds new functionality to crawl websites using saved browser profiles directly from the CLI.
This includes:
- New CLI option to use profiles for crawling
- Helper functions for profile-based crawling
- Fixed type hints for config parameters
- Updated example to show browser window by default
This makes it easier for users to leverage saved browser profiles for crawling without writing code.
Adds new interactive browser profile management system that allows users to:
- Create and manage browser profiles for authenticated crawling
- List existing profiles with detailed information
- Delete unused profiles
- Use profiles during crawling with the new -p/--profile flag
Also restructures CLI to use Click groups and adds humanize dependency for better size formatting.
