LinuxCNC 2.9.6 released

LinuxCNC 2.9.6 has been released.

This is a bug-fix release. Shortly after the release of 2.9.5 it was noticed
that a fix for a graphics bug in Gmoccapy had resulted in the Axis touch-off
dialog box no-longer working for non-zero entries.

This update is for all users, but especially users of the Axis GUI.

Packages for 2.9-uspace for amd64 (PC) for Debian Buster, Bullseye, Bookworm
and Trixie and for arm64 (Raspberry Pi 4/5) for Buster and Bookworm have
been added to the linuxcnc repository. If you installed from one of our live
images or Pi SD-card images then the update should be available immediately.

If you installed into a normally-installed Debian from the Debian repositories
then hopefully the new version can be queued up for the next point release. If
you can’t wait then it is possible to add the LinuxCNC repositories to the apt
sources. One way to do this and install the security keys is via the shell
script here: https://linuxcnc.org/docs/stable/html/getting-started/getting-
linuxcnc.html#_installing_on_debian_bookworm_with_preempt_rt_kernel

At the moment the live-image installer and SD card images will install 2.9.4
but update should be trivial (and possibly automatic)

RTAI is still supported, but in the short term building from source is likely
to be the most expedient way to get 2.9.6 on that platform.
