Version 3.7.0beta10 was built on August 16, 2026.

Changes since 3.7.0beta9:

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.
