Hmm - of course I went looking for the past HN discussion and it seems there wasn't one - that's a bummer:

Show HN: Open-source version control for game developers - https://news.ycombinator.com/item?id=36485377 - June 2023 (0 comments)

(Hopefully we're making up for it with this one)

Edit: ah here we go: Show HN: A version control system based on rsync - https://news.ycombinator.com/item?id=34439461 - Jan 2023 (118 comments)

Actually this https://news.ycombinator.com/item?id=34439461 contains some great discussion about JamHub if people are curious. I changed the name from jamsync to jamhub. :)

Partially why I got so excited about version control is how well this post blew up when I posted.
