My Devuan ascii xfsprogs is still at 5.10.X . Daedalus has 6.1.X .

Reiserfs is, or was, the default FS for knoppix. I used it for years and
found it to be very stable.

Reiserfs 4 development is finished, but it suffers from a bug where if you
write to lots of little files then the FS has a tendency to corrupt. This
bug is very difficult to reproduce, so the devs haven't managed to track
it down to fix it yet.

The main (technical) reason reiserfs 4 was rejected from the linux
kernel, even for staging, was because it was using a plug-in system to do
everything instead of referring such work to the VFS block system.

Reiserfs 5 is in development, but the progress seems to be quite slow and
it's not open to public contributions or download at this time.
