Github today announced new release of GitHub for Mac, codenamed Kona. You can download the latest version yourself directly from mac.github.com.

The biggest addition in GitHub for Mac is the ability to autocomplete GitHub usernames right within the commit summary and description fields. It works just like comment fields on GitHub.com, and almost everywhere else in the technology world: type @, start typing either the username or name of the GitHub user you want to mention, and you will get the following popover:

github autocomplete 520x365 GitHub updates Mac app with username autocompletion, drops support for Snow Leopard

GitHub also took the opportunity today to stop supporting OS X 10.6 (Snow Leopard) in order to make use of the improvements available to developers in OS X 10.7 (Lion) and 10.8 (Mountain Lion). As of Kona, releases of GitHub for Mac will require Lion or later to run. Snow Leopard users will be stuck on the previous version and won’t see new updates going forward.

The official Kona changelog is as follows:

  • Fixed: Visual bug where the divider in the Changes view does not extend to the bottom of the window.
  • Added: Typing ‘@‘ in a commit message will now display a list of usernames to autocomplete.
  • Fixed: Displaying the initial commit in a repository shows phantom changed folders.
  • Fixed: Potential crash when attempting to click on the source list while it is being refreshed.
  • Fixed: Potential crash when a file is selected or unselected whilst the app is committing.
  • Fixed: Potential crash when changing files in, or leaving, the Changes view.
  • Fixed: Stashed changes aren’t restored if the branch is renamed.
  • Improved: Command-Left and Command-Right now properly move within the text boxes in the Changes view.
  • Fixed: Login sheet detaches from the window if you attempt to clone without being logged-in.
  • Improved: Updated the app’s internal git version to v1.7.12.1.
  • Fixed: Revert button incorrectly hidden on the HEAD commit.
