Stay up to date with the latest improvements, fixes, and new features.

February 27, 2026

Version 1.0.7 — Persistence and Stability

✨ New

• Chat history that stays with your project — Chat threads are now stored per workspace, so your conversations follow the project you’re working on and your active chat is restored when you return.

• Chat retention settings — Choose how long to keep chat history. Inactive threads beyond your chosen period are automatically removed to save space.

• Line diff when editing — When you edit a message or use the edit tool, you'll see a clear line-by-line diff of what changed.

• Improved write-file tool — The write-file tool has been updated for better reliability.

• Download Mirai directly from the web — A new download page lets you get the latest Mirai installer (DMG) directly from the website. The hero and footer now link to this page.

🐛 Fixes

• Scrolling — Fixed scrolling when viewing or editing older messages so the conversation stays easy to follow.

• Error messages — Errors are now shown outside the chat thread so they don't clutter the conversation.

• Command bar — More accurate calculations and line diff display in the command bar.

• Better summarization — Chat summarization has been improved with more accurate token handling and safer truncation.

• Sign-in experience — Removed the spinning wheel from the SSO login flow.

• Updates — The app now only prompts for an update when a newer version is actually available.

Version 1.0.6 — Developer Experience Refresh

✨ New

• [Opus 4.6] is here.

• [Pause / Resume Support] When your computer is locked or the application is closed, ongoing chats will be “Paused”. You’ll be able to press the “Play / Continue” button to keep going! No more “Continue” or “Keep going” prompts.

• [Chat queues] No more waiting—just queue messages up!

• [Atlassian and Github MCPs] come pre-configured in your mcp.json. Don’t like it? You can disable or remove them from mcp.json.

• [Draft persistence] Got something in your chatbox and you switch tabs? They stay now! If you open a new page, it’ll move over as well. Should feel very similar to other IDEs.

🐛 Fixes

• [Past Chats] button no longer opens a new chat and will show you the history page.

• [tsserver] is now bundled with the build. That’s why the warnings thought it was deleted—it didn’t come with the app. Now it does, and the error should disappear.

• [Checkpoints] work more reliably. No more losing half or more of your progress when going back into the past.

• [Summarization] no longer removes past chat history and works much more reliably.

• [The past chat scrollbar] was too large and made it difficult to click; we’ve turned it into a dropdown instead.

• [Knowledge base search] You shouldn’t get an error when you do the first knowledge base search any more.
