This update is all about making the software more stable and cheaper to run, especially for people using it for heavy-duty tasks like coding or long, complex conversations. If you use tools to help the AI do things, or if you write code with its help, this release makes your day-to-day experience a lot smoother.

Improvements

  • Smarter memory for long chats: The software now does a better job "caching" (temporarily saving) earlier parts of your conversation. This means it doesn't have to re-process the entire chat history every time you send a new message, which makes long chats respond faster and saves money on computing costs.

Fixes

  • Fixed chat history corruption: If you asked the AI to use a tool (like a calculator or web search) to do the exact same thing over and over, it used to glitch and duplicate the results, which eventually caused a "400 error" (a bad request error). This is now fixed.
  • Fixed frozen previews: If you were trying to view an embedded link or preview and your browser's privacy settings blocked cookies (tiny data files websites use), the page would get stuck refreshing over and over again in an infinite loop. It now handles this gracefully.
  • Fixed annoying pop-up messages: The software had a warning that popped up to tell you when you were repeating a tool request. It was a bit too sensitive and would sometimes lie, saying your requests were identical when they weren't. The warning is now smarter.
  • Fixed Windows login tools: Commands that let you use outside login services (like signing in with Google or GitHub) simply didn't work if you were using a Windows computer. They work now.
  • Fixed false "cancelled" alerts: Sometimes the system would tell you "Turn cancelled by user" even when you didn't cancel anything. That confusing glitch is gone.
  • Fixed coding assistant crashes: If you were writing C# code, the language server (the background program that checks your code for errors as you type) would crash on every single keystroke. That's fixed, and error-checking for other programming languages is more reliable, too.

Breaking changes
