From iTerm2
Changes since 3.7.0beta10:
Improvements:
- Scrollable tab bars are now on by default. Tabs that don't fit stay in the bar and are reached by scrolling instead of the "More tabs" overflow menu. You can turn this off in Settings.
- The built-in AI model list now includes Claude Sonnet 5, GPT-5.6, and the Gemini 3.x flash models, and the recommended defaults move to GPT-5.6 for OpenAI and Gemini 3.7 Flash for Gemini. Retired models (Opus 4.1, Gemini 2.0 flash) are removed.
- Settings > General > AI has a new "Automatically update available AI models" checkbox and an Update Now button. The model catalog can refresh itself from iterm2.com so new models appear without updating iTerm2; these controls let you turn the automatic check on or off and run a check on demand.
- The startup warning that a legacy script's pinned Python version will be bumped for the uv runtime now has an Upgrade Now button that migrates the affected scripts immediately, so a script you never launch no longer re-nags every launch.
- The tmux Dashboard's Open in Tabs button now works with a single selected window, matching Open in Window. Issue 12994.
- Dropping a local file on the terminal no longer offers to upload it over scp when your machine answers to more than one name (for example a .local name versus a DHCP-assigned name).
Bug Fixes:
- Fixed several AI chat request bugs on the OpenAI Responses API: every turn after the first could reach the model as bare context with the user's newest message dropped; some tool schemas were rejected with an HTTP 400 under strict mode; and a JSON null inside an array could crash the response parser.
- A selected tab in a scrollable tab bar no longer paints over the tab bar's rounded border.
- On macOS Tahoe, the tab bar overflow menu no longer drops the first hidden tab: with one hidden tab the chevron opened an empty menu, and with more the first was missing.
- Cmd-W now closes the Companion Device Settings window instead of beeping.
- The Companion Device Settings window no longer fires the Touch ID / password prompt on its own when opened or after unpairing. It shows a "Show QR Code" button and authenticates only after you click it.
- Fixed various crashes.
