CentOS-Announce No Comments

We are pleased to announce the immediate availability of CentOS-6.3
for i386 and x86_64 Architectures. Release Notes for 6.3
are available at –
we recommend everyone looks through those once.

CentOS-6.3 is based on the upstream release EL 6.3 and includes packages from all variants. All upstream repositories have been combined into one, to make it easier for end users to work with.

All updates released since upstream 6.3 release are also released to the CentOS-6.3 mirrors.

Upgrading from CentOS-4 or CentOS-5:

We recommend everyone run through a reinstall rather than attempt an inplace upgrade from CentOS-4 or CentOS-5.

Upgrading from CentOS-6.0 / 6.1 or 6.2

Unless you have edited your yum configs, a ‘yum update’ should move your machine seamlessly from any previous CentOS-6.x release to CentOS-6.3

Downloading CentOS-6.3 for new installs:

When possible, consider using torrents to run the downloads. Usually its also the fastest means to download the distro.

Torrent files for the DVD’s are available at :

You can also use a mirror close to you :

Most mirrors will allow direct DVD downloads over http, ftp and rsync.

Please keep in mind that not all mirrors are currently updated, some might take upto another 24 hours before they have all the content.

We have also made efforts to try and ensure that most install types and roles can be run from DVD-1 itself.

Getting Help:

The best place to start when looking for help with CentOS is at the wiki

Contributing and joining the project:

We are always looking for people to join and help with various things in the project. If you are keen to help out a good place to start is the wiki page at . If you have questions or a specific area you would like to contribute towards that is not covered on that page, feel free to drop in on for a chat or email the CentOS-devel list

Thanks to everyone who contributed towards making CentOS 6.3, specially the effort put in, as always, by the QA team.

A special shout out to all the donors who have contributed hardware, network connectivity, hosting and resources over the years. The CentOS
project now has a fairly well setup resource pool, purely thanks to the donors.
