Nothing concrete from what I can tell. Becoming a hard fork is relatively recent though (mid-November of last year, roughly).

As a side note, I understand why Gitea and Forgejo went for a "copy GitHub Actions" approach to their CI, but man do I wish more self-hosted repo software tried to copy Drone/Woodpecker instead. Iterative containers in the pipeline is such a smoother build experience, and it kind of sucks that Gitness is the only one doing it (that I know of).
