Gen_Devices/AllCommands.h (or something like that) had a booboo for a gazillion years. It was fixed by phenigma 17 month ago, which brought all new bins to all of us. However, after that fix, others committed older versions of that file, reverting phenigma's fix, so we ended up with binaries containing different states of the header file. So far, the upgrade seems to go through painless, from what I and phenigma have experienced in our installs.
