v0.1.0
2026-06-16Highlights
- Bearer-First Origin Sessions: Direct login and registration now store bearer tokens for the origin server and use them for GraphQL HTTP and WebSocket authentication, with cookie fallback kept for compatibility paths.
- More Predictable Chat Entry: Returning to Chatto now remembers the last DM room as well as channel rooms, so the default chat entry points reopen the conversation you were using.
- Fresh Sessions Show Navigation: Fixed an issue where persisted sidebar state could hide primary navigation or room panels on a fresh session.
Upgrade Notes
- Client Authentication: Client developers should expect origin GraphQL requests and subscriptions to prefer bearer-token authentication after direct login or registration. Existing cookie-compatible paths remain available where needed.
- 0.1 Data Model: Server operators should continue treating this as the 0.1 event-sourced architecture. Pre-0.1 boot import paths are not part of this release line.
