There have been a few iterations with the hot end mounts where the versioning in the repo hasn't been changed. The initial 0.4.9.2 used a JHead Lite style hot end with mechanical endstops. There is now a traditional JHead version from Serge that uses a PCB mount end stop. I haven't pushed any of my changes for a few weeks, the original JHead Lite files for mechanical endstops are at [
github.com] . There are some other parts changes where the release version wasn't incremented as well.
