What's New
Drastic shift from Git VCS to AI agent framework with breaking API and UI changes
Breaking Changes
- Removed legacy file-editor modal in favor of unified shared Editor
- Made `llm_result` a required parameter in `hist_add_ai_response`
- Moved File Browser controls into a dedicated Settings category
New Features
- Unified text and code editing in shared Editor with ACE syntax highlighting
- Introduced CLI tools `a0-create-plugin` and `a0-manage-plugin`
- Movable and customizable canvas rail with improved UI responsiveness
- Independent, lazily loaded directory trees with unified styling
- Enhanced Responses API preserving native tool calls
Improvements
- Enforced negotiated WebSocket payload ceilings and atomic HTTP file transfers
- Enhanced prompt engineering efficiency and Context Doctor
- Improved UI responsiveness and bounds checking for Canvas
- Centralized streamed file transfers
Upgrade Notes
Code using the legacy file-editor modal must migrate to the new shared Editor. Ensure the `hist_add_ai_response` function includes the required `llm_result` parameter. Update UI references as File Browser controls have moved to Settings.
