LinuxCNC 2.9.2 has been released.

This is a bugfix release, with the most obvious change being that run-from-line in the Axis interface should now be working again.

Packages have been prepared for:

Buster - uspace - amd64 (PC) armhf (Pi) arm64 (Pi with 64-bit kernels)

Buster - RTAI - amd64

Bullseye - uspace - ams64 (only)

Bookworm - uspace - amd64, arm64

Bookworm - RTAI - amd64

For existing users of 2.9.1 on the above platforms this should be offered as an automatic update.

If anyone badly needs Bullseye debs for RTAI or arm64 / armhf then let me know. (all but the amd64 uspace builds have to be manually created)
