I can understand (perhaps) bug fixes not being in the release notes but for something like this they should let owners know of the change.
I'm really not sure they should. They make a lot of little changes like this and it really isn't something that's going to affect me in a major way. It's a self-explanatory protect function that tells you everything you need to know if you happen to try meet the criteria required for it to override your command. I don't really want to sift through these types of things when reading about the major new features.
