Upgrade Git to 2.12.3 or 2.13.0

Git 2.12 Release Notes

Backward compatibility notes.

  • Use of an empty string that is used for 'everything matches' is still warned and Git asks users to use a more explicit '.' for that instead. The hope is that existing users will not mind this change, and eventually the warning can be turned into a hard error, upgrading the deprecation into removal of this (mis)feature. That is not scheduled to happen in the upcoming release (yet).

  • The historical argument order "git merge HEAD ..." has been deprecated for quite some time, and will be removed in a future release.

  • An ancient script "git relink" has been removed.

Git 2.13 Release Notes

Backward compatibility notes.

  • Use of an empty string as a pathspec element that is used for 'everything matches' is still warned and Git asks users to use a more explicit '.' for that instead. The hope is that existing users will not mind this change, and eventually the warning can be turned into a hard error, upgrading the deprecation into removal of this (mis)feature. That is not scheduled to happen in the upcoming release (yet).

  • The historical argument order "git merge HEAD ..." has been deprecated for quite some time, and is now removed.

  • The default location "/.git-credential-cache/socket" for the socket used to communicate with the credential-cache daemon has been moved to "/.cache/git/credential/socket".

  • Git now avoids blindly falling back to ".git" when the setup sequence said we are not in Git repository. A corner case that happens to work right now may be broken by a call to die("BUG"). We've tried hard to locate such cases and fixed them, but there might still be cases that need to be addressed--bug reports are greatly appreciated.

Note: Git 2.13 includes the SHA-1 collision detection (gitlab-org/gitlab-ce#29785).
