Several years in the making, GitLab is now very actively implementing #ActivityPub! 🙌
https://gitlab.com/groups/gitlab-org/-/epics/11247
The end-goal is to support AP for merge requests (aka pull requests), meaning git.alice.dev can send a merge request to gitlab.com/Bob/project.git
First bite-sized todo on the implementation path there is ‘subscribe to project releases’.
Smart move by #GitLab; through ActivityPub they’re getting a distributed version of GitHub’s social layer.
