Under the hood
- Responses API server-sent event streams now have dedicated error handling, so failures on the stream can be represented and surfaced as structured errors.
- Model-provider selection includes workspace-aware routing.
- Skills now keep a world-state layer for session context.
- Realtime-history presentation has been removed.
- API payloads around installed apps, catalog budget allocation, credit and usage responses, previous-turn settings, PR output, and cloud requirements were updated; unused sandbox-state arguments and some older account, plugin, and remote-pairing types were dropped.
- Client-message notifications were simplified by dropping the separate chunked event.
- Dependencies were refreshed.
