We're currently are in the process of replacing GitLab and are migrating to Gitea. The new Gitea instance can be found at https://gitea.zom.bi but will ultimately also be reachable via https://git.zom.bi. We will migrate your repositories to Gitea, but you can help us by migrating them yourself (see how in the wiki https://w.zom.bi/index.php/Git#Migrate_a_project_from_GitLab_to_Gitea)

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'
