x86_64 - This distribution supports AMD (Athlon 64, Opteron) and Intel Pentium (Xeon EM64T) processors.
ia64 - This distribution supports Intel Itanium2 processors.
s390 - This distribution supports IBM S/390 processors.
s390x - This distribution supports IBM Z-Series servers.
alpha - This distribution supports the DEC Alpha processor.
There may be a separate release announcement for individual architectures.
--------------------------------------------------------------------
Current CentOS 4 users may upgrade by using up2date or yum and the normal upgrade process using the following commands:
yum upgrade
or
up2date -u
--------------------------------------------------------------------
The CentOS specific release notes for this upgrade are available here: http://mirror.centos.org/centos/4/os/i386/RELEASE-NOTES-en.html
Documentation for CentOS 4 (including upstream release notes) is available here: http://mirror.centos.org/centos/4/docs/
You may download the installation CD or DVD ISOs via bittorrent from this link:
http://mirror.centos.org/centos/4/isos/
CD ISOs may also be downloaded via publicly available external mirrors: http://www.centos.org/mirrors/
--------------------------------------------------------------------
Major changes in this version of CentOS include:
1. Upgraded yum. Yum has been upgraded to version 2.4.x, which adds a sqlite database backend for local metadata storage. This allows yum updates to be much faster than they were previously. The following packages are added or upgraded to facilitate the new yum: createrepo, centos-yumconf, sqlite, sqlite-devel, python-elementtree, python-sqlite, python-urlgrabber, yum.
2. SystemTap. CentOS-4.2 contains a technology preview release of SystemTap. SystemTap is a dynamic system profiling framework. SystemTap is only included as a preview, and should not be used in production at this time. Please see the SystemTap website for more information: http://sourceware.org/systemtap/
3. Updated and added packages. There is a list of all packages either added or upgraded since CentOS 4.1 in the upstream release notes, please see the upstream release notes for your architecture for CentOS-4.2 on the CentOS documentation page: http://mirror.centos.org/centos/4/docs/
--------------------------------------------------------------------
ISSUES:
There is a known issue upstream when upgrading x86_64 servers. The issue seems to be related to the new audit and kernel packages when performing an upgrade. If you first install the new kernel and audit packages, then reboot and upgrade the rest of the packages, it seems to minimize this problem. Please see this bug report: http://bugs.centos.org/view.php?id=1037

There was a slight problem on upstream provided sources and as i knew about it, i could not let the installation images go out in state where one would have hanging X after firstboot (new installations) or hanging X after boot. The xorg-x11-package is modified to disable DRI on Radeon 7000 (RV100) which is common on ia64-hardware as in the RX1600/RX2600 MC/ILO-board integrated VGA-conroller.
The other thing is that the shipped mx-package, if installed, will render new yum unusable. The fedora-devel version mx-2.0.6 (the shipped one is mx-2.0.5) doesn't have this problem and there is so little changes that i just decided to ship with the new version. We really wanted to get new yum on this release as it's using sqlite backend and should work much faster after initial update.
alpha - This distribution supports the DEC Alpha processor.
This baby has been a long way. I did make it release now as there is no reason to drag is as beta/rc for ever. It's not perfect, but it has been working for me very very good. Specially the patched kernel has been zero trouble free for what i've used it. Stable and working.
Now it's more like community thing to get things even better. There are lot of mods from mainstream centos on this arch. Most of those are just fixes to make things compile on alpha/axp tho.
The xorg-x11/radeon/DRI is fixed here too, but more radical manner. It's disabled for all radeon by default as i really don't render the X unusable after installation, which was case in my tests on Radeon 9250/PCI. If it's resolved later, there will be update on xorg-x11 to enable this.
So if you're a user, i am open for hearing about problems. Some of those might be features and some fixable, but i am only one man with lmited amount of hardware, so feedback is pretty much essential on making this even better with centos-4.3 time frame.
DVD-image should be bootable even on IDE/DVD-drives now too. I made ordering on the mkisofs, so the crucial parts are all located on begining of the DVD. At least it now worked on my ES45 w/ generic IDE/DVD-drive. Also the small boot.iso is there for network installations.
The latest version of tog-pegasus didn't quite make it in this. It doesn't weirdly sefault on late build process, but i didn't have time to dig it really further yet. The tog-pegasus in the one that was in BETA-set of sources. (i don't know if that even works tho :)
SPECIAL NOTE:
If you did install the 4.1beta for axp, you do have later kernel in your system and the release kernel won't get 'updated'. One must make manual actions to get the kernel installed if that is wanted. There is something on these beta -> rel updates always.
There should be new centos-release dropped on 4.1beta updates. That file, after updated, should direct all the beta-installations directly to release tree with pretty much automatically. If not, you should fetch it manually and install with rpm.
