I can see there's a repo with kde core packages 4.8.5 for OpenSUSE 12.2 which I'm using right now. Upstream 4.8.5 has obviously some additional bugfixes comparing to the previous 4.8.4 but OpenSUSE official 4.8.4 has some own distribution patches. So what's better from the stability point of view? Additionaly, what's different in the official release comparing to the upstream generally? I have also Arch with 100% vanilla kde and subjectivelly it seems all the same so far except some unified greenish artwork. Thank you for your time.
