What's New
Go client implements AHP 1.0.0 with SDK API and protocol compatibility changes
Breaking Changes
- FileEdit and preview edits now use named models, breaking SDK APIs
- Protocol compatibility baselines are restricted to 1.0.0 and 0.9.0
New Features
- Background work support for chat-owned shells and subagents
- Atomic chat transfer and canvas metadata synchronization
Improvements
- Lightweight chat navigation data exposed without requiring a session subscription
- Enhanced automation support including customizations, disable conditions, and run counting
Upgrade Notes
Regenerate generated SDKs due to named model changes in FileEdit and preview edits. Ensure your host or client only targets protocol compatibility baselines 1.0.0 or 0.9.0.
