I have just fixed up a couple of issues with tags and how they are displayed. I am now considering the Drupal 6.x version feature complete and other than bugs I am not going to be working on this version.
I am going to be starting now to work on the Drupal 7.x version which will take advantage of things like the stream wrappers to be able to access the file contents of the git repository and be able to take advantage of the new updating system.
Fix up some issues with detecting the current branch when checking out a tag. This pulls into the entire origin instead of just the current branch, so the is enough information to find the current branch from the currently checked out tag.
