LinuxCNC 2.7.5 has been released.

This release includes a fairly large change to the controller, intended to make Abort (eg, hitting Escape while running a program in Axis) work more correctly. This change also affects controller startup, including the processing of [RS274NGC]STARTUP_GCODE. Please be on the lookout for any surprises in these areas, and let us know if you notice anything amiss.

This release also includes many other bug fixes, especially in PncConf and Stepconf, the Gmoccapy GUI, GladeVCP, the ‘carousel’ toolchanger component, and more.

All 2.7 users are encouraged to upgrade.
