If I remember correctly, Makkonen got the Touch Pro up to speed with the rest of the development and there wasn't as big of a need to have a separate build anymore. Correct me if I am wrong Makkonen?
As far as those files, earlier builds would create those for some reason pertaining to startup/shutdown, but as the devices were not shutting down correctly anyways, they were not needed. Newest build has shutdown working, and there has been a good amount of other changes since July as well.
