The only sad thing is that the previous no-updates message has been replaced. It used to read "Congratulations! Your apps are up to date (or your repositories are out of date)."
This always tickled me as a perfect evocation of the open-source software spirit: cheerful, optimistic, mildly pedantic, and technically correct.
The new message omits the parenthetical. More user friendly, but missing a bit of FOSS personality.
