There was literally a commit only a few hours ago and there doesn't seem to be any announcement about it being archived or abandoned. I feel like this has to be either a mistake or some disgruntled ownership drama but I think it's pretty fair to assume it's not abandoned, however this shakes out there will still be people working on it or some fork of it.

maybe it's finished

Hmm, it shows archived on Jun 2 for me, but this person’s screenshot says May 31:

So did they unarchive it, make two commits, and then archive it again?

Should I rewrite it in D, so not everything gets rewritten in Rust?

And someone just committed to it only 2 hours ago. That’s really strange.

As far as I am concerned, “upstream” jemalloc development has concluded.
