What's New
Newer release adds automation workflows and durable errors, requiring session and terminal handling updates.
Breaking Changes
- Annotations now carry a required `origin` field with a session URI.
- Renamed session lifecycle value `creationFailed` to `failed`.
- `TerminalSessionClaim` now requires the owning chat URI.
- Terminal state lifecycle is now explicitly `running` or `exited`.
- `SessionToolClientExecutionRequest.toolCall` is restricted to running state.
New Features
- Automation catalogue and automation-run channels for shared workflows.
- Turn errors are now durable and resumable via `chat/turnResume`.
- Host extensions can advertise capabilities via `InitializeResult._meta`.
- Annotations now support optional chat URI and turn ID fields.
- Session lifecycle management and terminal claims are improved.
Improvements
- Generated clients now preserve unknown values for nonexhaustive enums.
- Automation catalogue snapshots now use `AutomationState.entries`.
Upgrade Notes
Update code to handle the new `origin` field on annotations and ensure session lifecycle checks use the renamed `failed` value. Modify `TerminalSessionClaim` to include the required chat URI.
