The CentOS development team is pleased to announce the release of CentOS 4.6 for i386, x86_64, s390, s390x and ia64. It is available on all CentOS.org mirrors and via bittorrent, see this link to download ISOs:

http://isoredirect.centos.org/centos/4.6/isos/

This release corresponds to the upstream vendor U6 release. Also released in the updates repository for CentOS-4.6 are all updates through December 15th, 2007.

The work for the i386 and x86_64 ServerCDs is in progress.

If you are currently using another version CentOS-4 version, using this command will upgrade you to CentOS-4.6:

yum update

--------------------------------------------------------------------
Major changes for this version are:

* samba has been updated to version 3.0.25b. This addresses several critical issues affecting interoperability with Windows 2003 and Windows Vista (resolved in recent upstream releases).

* autofs5 is included in this release as a Technology Preview. This new version of autofs resolves several long-standing interoperability issues in multi-vendor environments.

* 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.

* A new yum included in CentOS-4.6 requires the installation of yum-metadata-parser. The yum-metadata-parser package contains a metadata parser for yum written in C. It speeds up the metadata parsing phase of yum considerably and does not change yum behavior in any other way.
