This update breaks the updates policy. It is a non-essential major version update which makes irreversible changes to the DB format, preventing the same file being used by old clients. Changing the major version was not needed because upstream are still providing security support for the old version "for some time". However, now that the change has already been pushed to F23 arguably it's better to change F22 as well, to at least allow DB files to be shared between F22 and F23 machines.
powerdevil in this update completely borks the system, preventing kded5 from running, which makes kwallet (so you can't even easily get on wifi to downgrade again!)
