-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1

We are pleased to announce the immediate availability of CentOS-5.7 for i386 and x86_64 Architectures.

CentOS-5.7 is based on the upstream release EL 5.7 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-5.7 can be found on-line at : http://wiki.centos.org/Manuals/ReleaseNotes/CentOS5.7 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-5.6 ( or CentOS-5.0/5.1/5.2/5.3/5.4/5.5):

If you are already running CentOS-5.6 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-5.7, run : 'rpm -q centos-release' and that should return: 'centos-release-5-7.el5.centos.1'

If you are running CentOS-5.6 and have the CR repo enabled, a simple 'yum update' will still move your machine to 5.7. But since the CR repo already contained all the 5.7 updates, there will only be a handful of rpms that need to be installed for the 5.6 to 5.7 upgrade. If you are not running the CR repo, we highly encourage everyone to install and run this repository on their machines. More details on the CR repo can be found online at http://wiki.centos.org/AdditionalResources/Repositories/CR

+++++++++++++++++++++++ Downloading CentOS-5.7 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 a hundred people seeding CentOS-5 and it's possible to get upto 100mbps downloads via these torrents.

While torrent files will do their own content checks, and only the right torrent will register and download from torrent.centos.org - its very important for your own security that an md5/sha1sum check is done on the .torrent file itself, and ensure that only the torrent.centos.org tracker is being used. Sha1sum's are more secure than md5's. Whenever possible, use sha1sum's instead of md5.

- -- 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.

+++++++++++++++++++++++ Note about media:

We have tried to standardise on the media between the i386 and x86_64 architectures. Each now has the same number of CD images and the same number of DVD images. CD #8 on i386 contains no rpms, and is not needed for any install type. DVD #2 on both i386 and x86_64 only contain Openoffice langpacks for languages others than english. Therefore DVD#2 is only needed when doing a desktop install, with the openoffice components selected with other than English language support.

+++++++++++++++++++++++ Sources and Debuginfo packages:

srpms and debuginfo packages are still making their way to the CentOS mirrors and should be online by the 20th September. We are considering changing the way we handle sources and debuginfo rpms in order to better manage publishing them and to free up mirror space. For now there will be no change to the way things are running. Any change will be communicated clearly, and we will do our best to make sure it has as little user impact as possible.

+++++++++++++++++++++++ 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. And a special shout out to all the donors who have contributed machines, bandwidth and infrastructure towards the CentOS Project.

Enjoy!
