A lot of their early value-proposition were saner security defaults and additions to increase confidence in the software's security. A lot of the changes were attempted to upstream into Gitea, but not everything made its way in. They were a soft-fork for a while before hard-forking, and even after the hard-fork continued to sync changes from Gitea where possible.

Forgejo v10 is the first release I've seen where there's been a focus on tiny UX improvements (versus trying to remain compatible with Gitea). I'm hopeful these will continue to come, but it does still feel essentially identical in appearance and functionality with Gitea.
