What

When a conversation is resumed, the available tools, allowed agent types, slash commands and MCP configuration are now read fresh at that moment instead of being inherited from whatever the previous screen was holding. Changes you made to MCP servers or commands take effect on resume.

Details
  • API key re-verification now goes through the shared verification path with current credentials rather than a value passed down.
