We are pleased to announce the immediate availability of CentOS-5.1 for the i386 and x86_64 Architectures.
CentOS-5.1 is based on the upstream release 5.1, 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.
Further Arch support for PowerPC, IA64 and Sparc are planned and will be released soon. These arch's will follow the existing pattern of release to Beta first, and then to Final.
This is the first release where we are also publishing a special netinstall iso that can be used to start a remote install. Its included in the isos/ directory. This iso is in addition to the boot.iso published in the images/ directory of the distribution - there are no changes to that file.
The distro release notes are only available online at http://wiki.centos.org/Manuals/ReleaseNotes/CentOS5.1/ . The release notes include important changelog info as well as notes about the installer and outcomes from test situations which the centos-qa team worked through. Its considered essential reading.
Upstream release notes are available in the NOTES/ directory of the install media, as well as online at http://www.centos.org/docs/5/ . These include release specific technologies, new features in the distro and other misc information that can help you better utilize the distro. Always something worth reading.
