General improvements

More room for the work: MCP Apps, smarter mentions, and a smoother path from context to action.

New

This release added support for MCP Apps and made @ mentions switch the active assistant when Multi‑Agent mode is off.

Better

Long pasted text became editable attachments. Audio files gained transcription with an OpenAI key. The release also refined prompt caching, document retrieval, and tool and image handling.

Fixed

MCP OAuth fixes improved connections, while legacy SSE transport support was removed.
