The CentOS team today released CentOS 5.1. This is good news there has been a ton of bug fixes upstream.
It is still trickling out to a few mirrors so should be available everywhere soon, I updated my 2 development servers using:
yum –disablerepo=\* –enablerepo=base –enablerepo=updates update
And so far it is all good, be aware that there seems to be a small issue with /etc/redhat-release still showing things as it was with 5.0, but this will probably be fixed soon as there has already been mentions of this on the forums.
As always, read the release notes before you upgrade as there are some outstanding issues you should know about.
Well done, the Wiki has also recently had a layout upgrade and it is all starting to look much more professional than before.
