Can someone tell me what this is in reference to.
Yeah that was it, they were using SVN before. They migrated to their own self-hosted Gitlab instance.Also, I'm a bit surprised that Arch wouldn't keep doing their own thing and moved to Git. It's probably a lot less expensive than hosting it themselves, though surely they have a sponsor who provides all that.
Entirely unrelated, I was once pretty efficient with SVN. I don't think that's as widely used today, but I digress.
