I just tried the new build and it breaks CEC control. I found the problem already.
kodi.log reported
03:18:07 12.709553 T:1959215664 ERROR: Unable to load libcec.so.3.0, reason: libcec.so.3.0: cannot open shared object file: No such file or directory
So I found that that file didn’t exist in /usr/osmc/lib/ so I just created a symlink to libcec.so.3.0.1 and rebooted which fixed it.
