Message: 1 Date: Wed, 02 Mar 2011 15:37:36 -0600 From: Johnny Hughes johnny@centos.org Subject: [CentOS-announce] CentOS 4 i386 and x86_64 release of CentOS-4.9 To: CentOS-Announce centos-announce@centos.org Message-ID: 4D6EB8A0.7030508@centos.org Content-Type: text/plain; charset="windows-1252"

The CentOS development team is pleased to announce the release of CentOS 4.9 for i386 and x86_64.

This release corresponds to the upstream vendor 4.9 release.

Also released in the updates repository for CentOS-4.9 are all updates through March 1st, 2011.

If you are currently using an older CentOS 4 version, using this command will upgrade you to CentOS-4.9:

yum upgrade

NOTE: The upstream provider did not respin media for the 4.9 release and therefore the CentOS project will also not respin our install media. Installs moving forward will be off the 4.8 media and an upgrade will move you from version 4.8 to version 4.9. We do this to maintain compatibility with 3rd party kernel drivers which are designed to be installed as part of the installation process.

This is the last expected set of changes to add new functionality to the CentOS 4. We will continue to provide security updates and bug fixes for CentOS 4 until its End-of-Life scheduled for February 29, 2012.

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

* The kernel-utils package provides microcode_ctl utility code and the microcode data itself ? supplied by Intel ? to assist the kernel in updating the CPU microcode at system boot time. This microcode supports all current Intel x86- and Intel 64-based CPU models and takes advantage of the mechanism built-in to Linux that allows microcode to be updated after system boot. When loaded, the updated microcode corrects the behavior of various Intel processors, as described in processor specification updates issued by Intel for those processors. In the CentOS-4.9 release the kernel-utils package has been updated with the 2010-09-14 version of Intel's microcode.

* OProfile in CentOS 4.9 now supports Intel Xeon (formerly codenamed Nehalem) processor performance events.

* The KornShell (ksh) package in CentOS 4.9 has been upgraded to the upstream release version ksh93t+.

* CentOS-4.9 provides an updated coreutils package, containing checksum utilities for the whole SHA-2 family, allowing a user to easily count or verify SHA-224, SHA-256, SHA-384, and SHA-512 checksums.

* CentOS-4.9 features version 3.6.13 of the Mozilla Firefox open source web browser.

* SystemTap in CentOS-4.9 has been updated to version 1.3. Most notably, this update provides support for the newer kprobe capabilities.

* OpenOffice 2.0 is now included in this release as a Technology Preview. This suite features several improvements, including ODF and PDF functionalities, support for digital signatures and greater compatibility with open suites in terms of format and interface. In addition to this, the OpenOffice 2.0 spreadsheet has enhanced pivot table support, and can now handle up to 65,000 rows.
