I just updates to 4.5.4 from 4.5.3 from the openSUSE 4.5 stable repo and when I open aboutKDE (from most KDE apps; Help->About KDE), it says I have KDE 4.5.3 Release 1! I hope this is just a string problem.
Hello Lin-unix,
Did you restart KDE after updating?
It might be caused by the fact that KDE is still running.
If it still shows the wrong version then maybe not all packages are updated?
Good luck!
I have that too. Also take a look here (post #2):
Release 45 Repo moves to 4.5.4
So, this doesn’t appear to be indicative of anything severe.
