CentOS 5.5 Released

The CentOS team just announced the release of CentOS 5.5.

The wiki has the Release Notes. Most major changes can be found in the RHEL 5.5 release information (which CentOS is based).

yum update
should update your system. Keep in mind the recent post-release updates should be syncing with the CentOS mirror soon.

As always, relatively smooth sailing with CentOS!
