Unfortunately, we lost some old, long unsused repositories recently. You can restore them by creating a new, empty repository in the project view and then pushing there using something like for x in $(git branch -r | grep -v HEAD); do git push origin $x:refs/heads/${x#*/}; done; git push --tags

The SSH username for accessing EduGit changed: Please update your remotes to use git@ instead of gitlab@.

Tags give the ability to mark specific points in history as being important
Repository has no tags yet.
Use git tag command to add a new one:
git tag -a v1.4 -m 'version 1.4'
