"CentOS-5.5 is based on the upstream release EL 5.5 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.

This is just an announcement email, not the release notes. The Release Notes for CentOS-5.5 can be found on-line at : http://wiki.centos.org/Manuals/ReleaseNotes/CentOS5.5 and everyone is
encouraged to look through them once. Also worth browsing through are the CentOS FAQs at http://wiki.centos.org/FAQ

+++++++++++++++++++++++
Upgrading from CentOS-5.4 ( or CentOS-5.0 / 5.1 / 5.2 / 5.3 ):

If you are already running CentOS-5.4 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-5.5, run : 'rpm -q centos-release' and that should return: 'centos-release-5-5.el5.centos'

+++++++++++++++++++++++
Live-CD:

LiveCDs for CentOS-5.5 on i386 and x86_64 are being released at the same time as the main distro. The LiveCDs are meant to be used to run a CentOS 5.5 environment or to start a network based install. The LiveCDs are setup in a way so as to allow running from either optical media like cds and dvds or from USB keys and other portable media.

+++++++++++++++++++++++
Change in iso counts:

The i386 distro is now spread onto 7 CD iso files, while the x86_64 distro is now 8 CD isos. The x86_64 DVD set is now spread over 2 DVD isos, while the i386 DVD remains as 1 iso file.

We've had to split the x86_64 dvd media over multiple disks due to the increase in the binary packages size. We have, however, tried to build them in a way that dvd#1 should be all that is needed by most people. x86_64 DVD#2 is limited to some OpenOffice.org language packages. x86_64 DVD#1 includes the rest of the distro and also includes the most popular OpenOffice.org language packs. More details on the exact split are available in the Release Notes.

Downloading CentOS-5.5 for new installs:

When possible, consider using torrents to run the downloads. Not only does it help the community and keeps mirrors from running up high bandwidth bills, in most cases you will find its also the fastest means to download the distro. There are currently over three hundred people seeding CentOS-5 and it's possible to get upto 100mbps downloads via these torrents.

-- Via direct download:
Due to bandwidth considerations the CentOS Project does not publish ISOS directly from our network machines. However direct downloads are available from external mirrors over http, ftp and rsync. A geoip based list is available at http://isoredirect.centos.org/centos/5/isos/ to give you the best predictable match ( and only lists mirrors that are updated already, so you don't need to waste time looking for a sync'd mirror )

Some mirrors also publish DVD images that can be downloaded directly. Refer to the mirrors list page at http://www.centos.org/mirrors for more details Mirrors that offer DVDs are clearly marked on the page.

srpms and debuginfo packages are still making their way to the CentOS mirrors and should be online within the next few days. Most sources are already in place, while the debuginfos are only stating to get uploaded now.

Getting Help:

The best place to start when looking for help with CentOS is at the wiki ( http://wiki.centos.org/GettingHelp ) which lists various options and communities who might be able to help. If you think there is a bug in the system, do report it at http://bugs.centos.org/ - but keep in mind that the bugs system is *not* a support mechanism.

A big thanks to everyone who contributed towards this release, including the translation teams, the qa team, the artwork team, the CentOS Developers and all the users out there. A special thanks to my fellow CntOS Infrastructure team members: Ralph Angenendt and Tru Huynh, who have both put in many extra-long days. And a shout out to all the donors who have contributed machines, bandwidth and infrastructure towards the CentOS Project.

Enjoy this release, tell all your friends about it too!
