This update is mostly about making the desktop app play nicely with the newest "current" servers (the background engines that actually do the work). It also fixes several bugs in how the app communicates with different AI models, making sure your chats stay smooth, smart, and logically organized.
What's new
- The desktop app now fully supports the newest "current" servers. This means the app can show live timelines of what the server is doing, stream text in real-time, and run commands directly from the server.
Improvements
- The desktop app is now smart enough to automatically detect whether it's connected to a brand-new "current" server or an older "legacy" server, so it works smoothly with both.
- When connected to the newer servers, the app hides old features that don't apply anymore, keeping your screen clean and uncluttered.
Fixes
- AI model fixes: Fixed how Claude handles "adaptive thinking" (the AI's ability to change its reasoning style). Also fixed a bug with OpenAI that was breaking some chats, and made sure Mistral remembers its reasoning from one message to the next.
- Search fixes: When searching files using the
greptool, if a result was a "symlink" (a shortcut to another file), the app used to lose the shortcut path. It now keeps the path intact. - Caching fixes: "Prompt caching" (saving parts of a conversation to speed things up) is now stabilized for Mistral, and the app now uses the correct save keys for different software kits.
- Interface fixes: Fixed the chat timeline so it updates instantly while the AI is typing, rather than making you wait. Also fixed an issue where paginated (multi-page) chat histories got scrambled out of order.
- File viewing: When you open a specific file tab, it now shows the plain file contents instead of confusingly showing a "diff" (a side-by-side comparison of changes).
- Security fix: The app stopped automatically accepting permission changes on new servers, which makes your setup safer.
