The CentOS development team is pleased to announce the availability of
CentOS-4.2 in the following architectures:

i386 - This distribution supports AMD (K6, K7, Thunderbird, Athlon,
Athlon XP, Sempron), Pentium (Classic, Pro, II, III, 4, Celeron, M,
Xeon), VIA (C3, Eden, Luke, C7) processors.

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


Current CentOS 4 users may upgrade by using up2date or yum and the
normal upgrade process using the following commands:

yum upgrade


up2date -u


The CentOS specific release notes for this upgrade are available here:

Documentation for CentOS 4 (including upstream release notes) is
available here:

You may download the installation CD or DVD ISOs via bittorrent from
this link:


CD ISOs may also be downloaded via publicly available external 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

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:



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:

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

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 :)


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.
