Full changelog

Highlights

Conversation-Scoped MCP

MCP servers are now managed per conversation instead of being synced globally to CLI agents, so each chat keeps its own toolset without affecting others.
Importing MCP servers from JSON now validates the payload up front — bad URLs, missing commands, or malformed configs surface as clear UI errors instead of silent failures or unhandled crashes.

Friendlier Agent Errors

- When an agent fails to respond, you now get a readable explanation with a suggested fix, plus retry and feedback actions, instead of a raw error dump. - Error tips survive navigation and reload, and submitting feedback on a failed message automatically attaches the relevant error details to help diagnose the problem faster.

WebUI

The local WebUI now opens automatically in your browser on startup, for both bun run webui and the packaged web build. Use --no-open or AIONUI_OPEN_BROWSER if you'd rather control this yourself.

Bug Fixes

The image generation toggle no longer flashes blue while the model is still loading.
Team conversation badges initialize from confirmation counts instead of refetching the full list for every team chat at startup, making launch faster.
The web backend now reuses its original port after a crash-restart, so the UI no longer loses connection to a stale port.
Quitting the app during backend startup is now treated as a normal cancellation rather than a startup crash.
Backend startup timeouts now record diagnostic detail (last health-check error and response) to make failures easier to debug.
