The CentOS development team is pleased to announce the release of CentOS
4.5 for i386, x86_64 and ia64.

It is available on all CentOS.org mirrors and via bittorrent.

This release corresponds to the upstream vendor U5 release.  Also
released in the updates repository for CentOS-4.5 are all updates
through May 16th, 2007.

The work for the i386 and x86_64 ServerCDs and all other arches is in

If you are currently using another version CentOS-4 version, using this
command will upgrade you to CentOS-4.5:

yum update

Major changes for this version are:

 * The up2date options "--undo" and "--list-rollbacks" are now
deprecated. You must use "yum remove <pkg_name>" or "rpm -e <pkg_name>"
to remove packages, or "rpm -Uvh --oldpackage --nosignature --nodigest
<pkg_name>" to revert to an older package.

 * CentOS-4.5 contains a Xen kernel that is now supported as a
paravirtualized (PV) Guest, but it cannot be used as a dom0.  There are
issues with erratic mouse movements in PV Guests that will be corrected
in future updates. You can install CentOS-4.5 PV Guests onto CentOS-5
machines, using the CentOS-5 Xen kernel as Dom0 and the CentOS-4.5 PV
Guest as DomU.

 * There is a technology preview of OpenOffice-2.0 included in the
updates directory.  You can install this OOo2 preview alongside the
current OOo-1.1.5 version, or you may install the OOo2 preview alone.
We apologize that this was not included on the ISOs, however it was not
on the upstream ISOs and we followed that layout.  To List the new
OpenOffice-2.0 RPMS with yum use this command:

       yum search openoffice.org2 | grep i386 | grep -v langpack

   For finding Language Packs (if you want other than English) do:

       yum search openoffice.org2 | grep langpack

   Use "yum install <pkg_name1> <pkg_name2>" to install the packages
that you want, or "yum info <pkg_name1> <pkg_name2>" to obtain more
information about them.
