iTerm2 3.7.0beta10

This version requires macOS 13 (Ventura) or later. macOS 12 is no longer supported. Sorry for the inconvenience!

New Features:

• Tab groups. Select tabs and gather them into a named, colored group marked by a chip on the tab bar. Groups stay contiguous, can be collapsed and expanded with an animation, and can be dragged as a unit within a window or out to a new or existing window. A right-click chip menu and a Firefox-style "Add Tab to Group" tab menu let you rename, recolor, close, or ungroup. Works on horizontal and vertical tab bars.
• Kitty terminal drag-and-drop (OSC 72). Programs that speak the protocol can accept files dropped onto the terminal window and can start a drag of their own content out to other apps, including across an SSH connection when using it2ssh.
• The left/right (vertical) tab bar can now be made scrollable: turn on the new setting and tabs that don't fit stay in the bar and are reached by scrolling instead of the "More tabs" overflow menu. This also works on horizontal tab bars.
• The uv-based Python runtime is now on by default. Newly created, imported, and migrated API scripts get a faster, self-managing interpreter instead of the bundled Python runtime. You can still override this in Advanced Settings, and already-provisioned scripts are unaffected.

Improvements:

• A new per-profile "Use ANSI colors for marks" setting (Profiles > Colors, off by default) draws command-prompt mark indicators using the color preset's ANSI blue, red, and yellow so they harmonize with your theme.
• The Advanced Paste indicator now has a keyboard toggle so you can switch a running paste between waiting for the shell prompt and sending keystrokes straight through, which lets you answer a password or other non-standard prompt mid-paste. Issue 5749.
• When a keystroke with a modifier matches no key binding by character but does match one for the same physical key (for example after switching keyboard layout or when an input method changes the character a key reports), iTerm2 now offers to turn on "Interpret key bindings based on physical key".
• The confirmation for closing a workgroup session now warns that the rest of the workgroup, its peers and their tabs, will close too.
• The ConEmu progress protocol's paused state (OSC 9;4;4) is now honored even when the percentage is omitted. Issue 723.

Bug Fixes:

• Restoring a session whose saved working directory no longer exists (for example a network drive that is not mounted at launch) no longer fails to relaunch the shell and silently closes the tab. Issue 12955.
• Decomposed Hangul jamo are now recomposed into a single cell instead of being split into separate cells. Issue 3063.
• The 16th parameter of an SGR trigger is no longer dropped by an off-by-one in the parameter store. Issue 722.
• Toolbelt list tools (Command History, Recent Directories, Captured Output) no longer draw their rows at zero width when a window opens with the toolbelt showing. Issue 12964.
• On macOS Tahoe dark themes, selected left/right tab chrome is drawn at the tab's real height again instead of a fixed cap-image height, so a custom tab bar height looks right. Issue 715.
• The top-right session indicators no longer smear while swiping between tabs.
• Fixed a window leak from the frame canonicalizer.
• A workgroup no longer shows a blank pane when it tears down while a non-main peer is on screen, and a peer host's toolbar now refreshes after its nested port is wired.
• Fixed word-boundary punctuation typos in the default settings. Issue 720.
• Fixed two format-string bugs in logging calls. Issue 712.
• Fixed various crashes.
