There hasn't been a release in 3 years and no news updates in 2 years until the recent GSoC announcement. Modern linux distros are still shipping a version from 2021 on a older version of Qt, unless you get a nightly unofficial release from the snap store. That's not a great sign even if there are commits happening. I used OpenSCAD a lot in college and I really hope it has a future. I'm glad to see it's getting sponsors now.
I understand that but a project can still be active even if there are no releases. A lot of software doesn't even get published as packages in distros.
