GitLab is used only for code review, issue tracking and project management. Canonical locations for source code are still https://gitweb.torproject.org/ https://git.torproject.org/ and git-rw.torproject.org.
The lastest version shown at https://guardianproject.info/repo/ is 12.0.3, while the Play Store and https://guardianproject.info/releases/ have 12.0.5.
The default FDroid repo lists an even older version.
