Mistral Vibe v2.23.0 Changelog

This update is all about making the software easier and more pleasant to use. It matters especially to developers and power users who spend a lot of time in the terminal, giving them quicker ways to manage tools, a cleaner interface, and a faster, less glitchy experience.

What's new

• Easier tool management: You can now use simple commands (vibe mcp add and vibe mcp remove) to connect to remote MCP servers (external programs that give the AI extra abilities). You no longer have to dig into config files to do this.
• Automatic themes: A new "Auto" theme follows your computer's light or dark mode, so the app always matches your setup.
• Cleaner tool displays: When the AI uses multiple tools at once, the results are now grouped tightly together so they don't clutter your screen.
• Desktop links: Added connections to ACP projects, making it easier to integrate with desktop apps.
• A/B testing tools: Added new built-in system tools to help run A/B tests (experiments comparing two versions of something to see which works better).

Improvements

• Simpler trust screen: When you open a folder, the safety prompt is simpler and defaults to "Trust folder" to save you a click.
• Less text clutter: Tool descriptions were shortened so they don't eat up the AI's limited memory (context bloat).
• Faster scrolling: Scrolling through really long conversations is now much smoother.
• No more lag spikes: Fixed a hidden issue where the app was unnecessarily recalculating text layout during animations, which used to cause stuttering.
• Major engine upgrade: The developers did a huge rebuild of the app's internal wiring. They replaced a messy system of direct connections with a standardized messaging system (JSON-RPC 2.0). This makes the core engine communicate with the user interface much more safely and reliably.

Fixes

• Word navigation: Fixed a bug where using Option+Left/Right arrow keys to jump between words in the chat box wasn't working.
• Lost "thinking" text: Fixed an issue where the AI's "thinking" notes were getting deleted if they weren't signed when replayed from the server.
• Mouse tracking: Fixed a glitch with how the app talks to your terminal emulator about mouse clicks.
• Resume crash: Fixed a crash that happened if you tried to delete a saved chat while resuming it.
• Config merging: Fixed a bug where completely empty settings would mess up the process of combining configuration files.
• Language settings: Fixed an issue in the bash (command line) tool where it was looking at the wrong language setting variable (LC_CTYPE instead of LC_ALL).
• Out-of-order text: Fixed a glitch where text would sometimes show up before the tool call that was supposed to generate it.
• Selection crashes: Fixed a crash that happened when trying to highlight text in certain detached parts of the screen.
• Mention errors: Fixed an OSError (system crash) that happened if you tried to auto-complete an @ mention that was way too long.
• First server setup: Fixed a bug where the system didn't properly create the registry when you added your very first server.
• Teleport ID bug: Fixed an issue where your conversation ID would get lost when using the "teleport" feature.
• Data retention link: Fixed a permissions bug so that regular users (not just admins) can now access the link to manage how long their data is kept.
