LinuxCNC 2.9.7 released 26 October 2025.
LinuxCNC 2.9.7 has been released. This is another bug-fix release to fix an unexpected interaction in a previous bugfix. (In this case the driver for the popular XHC pendants was incompatible with changes made to HALUI pin creation) In addition changes to the CI (continuous integration) in Github mean that the install debs will be available from the LinuxCNC Github repository under the "releases tab" This update is for all users, but especially users of the XHC pendants and Gmoccapy. Packages for 2.9-uspace for amd64 (PC) and arm64 (Pi) for Debian Buster, Bullseye, Bookworm, Trixie and Sid 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 This script has been updated to include a new, longer key required by Debian versions from Trixie onwards. 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 2.9.7 on that platform.
