This update is all about smoothing out the rough edges. If you use this software for complex coding projects, you will notice fewer annoying glitches, more accurate memory tracking, and faster performance when juggling multiple tasks.
What's new
- Clearer prompts: When the app asks you for input, it now shows easy-to-understand descriptions instead of confusing computer code (internal IDs).
Improvements
- Faster workspace setup: Creating a "worktree" (a temporary copy of your project so you can test changes safely) is much quicker because the app no longer wastes time copying old, unnecessary data.
- Smarter memory tracking: The app now accurately tracks "tokens" (the pieces of words the AI reads and writes). It used to overestimate how much memory it was using after undoing an action or switching modes, but now it gets the numbers exactly right.
- Better context estimates: If you are having a deep conversation that requires the AI to "think" (reasoning) before answering, the app's guess about how much chat history it can remember is now much more accurate.
- Instant status updates: The "context bar" (the visual meter that shows how much memory is left) now updates immediately when the app starts condensing your chat to save space, rather than freezing until it finishes.
Fixes
- Copying tables fixed: If you copied a table cell that had a lot of text, it used to insert weird, unwanted spaces where the line breaks were. That’s fixed.
- Recovering from connection blips: If the connection to an "MCP server" (an outside tool the app relies on) hiccupped for a second, it used to just stay broken. Now, it automatically tries again.
- Unfreezing subagents: If you interrupted the AI while it was using "subagents" (smaller helper bots doing background chores), it used to freeze up while waiting on totally unrelated tasks. It now handles interruptions smoothly.
- Less confusing error messages: If the AI's response got cut off because it was too long, the error message used to tell you to "ask for a shorter answer." That unhelpful tip is gone.
- Fixing a bug for .NET on Linux: If you code in .NET on a Linux computer, the app used to accidentally create way too many "watchers" (background trackers looking for file changes), which slowed things down. This is fixed.
- Stopping random pop-ups: The app used to show an automatic summary ("auto recap") at annoying times, like right in the middle of a background task streaming an answer. It now waits until the right moment.
