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.
