Mistral Vibe 3.0.0 lets the desktop onboarding import projects and sessions from another coding agent. Enabling the experimental model catalog adds Mistral’s curated models to the list while keeping config overrides. The Rust CLI now includes /leanstall and /unleanstall commands to install or uninstall the Lean agent. Use the new /branch command to fork the current conversation into a separate, resumable session. A built-in debug console opens with /debug or Ctrl+\ for live session logs.
