Karanbir Singh has announced the release of CentOS 5.4, a free, enterprise-class distribution built from source code for Red Hat Enterprise Linux: “We are pleased to announce the immediate availability of CentOS 5.4 for i386 and x86_64 architectures. CentOS 5.4 is based on the upstream release EL 5.4.0, and includes packages from all variants including server and client. All upstream repositories have been combined into one, to make it easier for end users to work with. And the option to further enable external repositories at install time is now available in the installer. For the first time, we are also releasing the i386 CentOS 5.4 live CD at the same time as the main distro.” See the release announcement and release notes for further information. Download (mirrors, SHA1): CentOS-5.4-i386-bin-DVD.iso (3,815MB, torrent), CentOS-5.4-x86_64-bin-DVD.iso (4,405MB, torrent).

================================
Upgrading from CentOS-5.3 ( or CentOS-5.0 / 5.1 / 5.2 ):

If you are already running CentOS-5.3 or an older CentOS-5 distro, all
you need to do is update your machine via yum by running :

'yum update'

Running 'yum list updates' before doing the update is recommended, so
you can get a list of packages that are going to be updated. To check
you are indeed on CentOS-5.4, run : 'rpm -q centos-release' and that
should return: 'centos-release-5-4.el5.centos.1'
