New CentOS 5.4 and Fedora 12 Beta both ship

The long-awaited CentOS update to 5.4 shipped yesterday! Release Notes and Mirrors (including .torrent files). Another great release in the line of a completely free, rock-solid stable Enterprise-grade Linux.

If you have an existing CentOS 5.x system configured to automatically update with Yum, or if you occasionally manually update via Yum, be sure to look at the Known Issues and follow these steps:

yum clean all
yum -y update glibc\*
yum -y update yum\* rpm\* python\*
yum clean all
yum -y update
shutdown -r now

Fedora 12 Beta also shipped yesterday with the customary Announcements, Feature List, and Common Bugs. Except for any major bugs (or even minor bugs), what versions you see in Fedora 12 Beta will essentially become Fedora 12.

It was a very busy day for the RedHat camps. I've very glad to see CentOS finally catch up to RHEL5.4 (all critical bugs were getting updated, but non-critical updates were awaiting the 5.4 release). I'm glad Fedora 12 has some great changes, like moving along the 32-bit code to drop pre-i686 processors and pick up a 1% speed boost, plus adding better compression for updates will be a nice change.

I'm curious to see if Fedora 12 will become what RHEL6 is based off of, or will they have time to squeeze out Fedora 13 first before the RHEL6 shipping in 2010 Q1? My guess is that they'll be basing it on F12.
