For a complete list of all changes, improvements, and bug fixes, please visit [our release notes page](https://www.git-tower.com/release-notes/mac).

### New 
- AI Commit Messages: Generate commit messages using AI directly from the Working Copy. Choose from different AI agents and prompts, manage them in Preferences, and assign them per repository or globally.
- Commit Action Bar: A new action bar in the commit message area provides quick access to commit templates, a hard line wrap toggle, AI message generation, and a resize handle — all in a redesigned layout with rounded text views and refined styling.
- Commit Body: You can now pin the commit message body to keep it permanently expanded.
- Partial Stash: You can now drag individual files from the Working Copy onto Stashes to create a partial stash, including untracked files.

### Improved
- Graphite: Performance with large numbers of branches has been significantly improved.
- Diff/Merge Tools: Tower now validates the tool configuration before launching and provides better error feedback on failure.
- License View: URLs in the license window are now clickable.
- Working Copy: Show File and Blame actions are now correctly disabled for untracked files.
- Workflows: The Git Flow tab in repository settings is now hidden when a non-Git-Flow workflow is active.
- Workflows: Updated icon for branch workflows.

### Fixed
- Fixed a crash related to the sidebar in tabbed windows on macOS 26.
- Fixed a crash that could occur when reloading history.
- Fixed a crash during app initialization that could prevent users from registering or using Tower.
- The fully merged badge and history banner now update correctly after fetch.
- Fixed an issue where worktree repositories could lose their connection to the main repository.
- Fixed unnecessary UI updates in repositories with Graphite or worktrees that could cause sluggish performance.
- macOS 26: Fixed an incorrect separator being drawn at the second split view divider in the toolbar. A proper tracking separator has been added for that divider.
- macOS 26: Disabled full size content scrolling for list and detail views to work around a system bug.
