We are planning to upgrade GitLab to the latest version this Friday morning. Expect some downtime! (oh, and there are still some GitLab stickers available at the C&CZ office ;-) )

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'
