As of June 2, 2025, jemalloc repository on Github has been archived. [1] I have a differential revision open for jemalloc 5.3.0 [2], but have no idea how we will fix bugs and improve jemalloc on FreeBSD after the archive.
We could fork the repository to freebsd/jemalloc and continue to develop by ourselves. Then, we need to build our own CI systems for jemalloc to test on macOS/Linux as well. I CC'ed Warner as he guided me for D41421, so I'm seeking for his advice this time as well. [1] https://github.com/jemalloc/jemalloc [2] https://reviews.freebsd.org/D41421
