CentOS 4 のサポート終了

ちなみに、他リリースのサポート終了は、CentOS5は 2014/3/31 、CentOS6は 2017/11/30になっています。


CentOS ML の内容は以下になります。
==========================================================================
All,

The CentOS-4 distribution (current version 4.9) will be at End of Life
on February 29, 2012.  That means there is only 3 months left in the
life cycle.

This coincides with the date that the upstream provider stops releasing
updates for their EL4 products.

Users who still need the EL4 platform can contact Red Hat for their
Extended Lifecycle Support (ELS) product:

http://www.redhat.com/rhel/server/extended_lifecycle_support/

Be advised that the upstream provider does NOT release their ELS source
code publicly and therefore after February 29, 2012 they will no longer
release security updates for their EL4 product line.

Soon after 1 March 2012, the CentOS-4.9 tree will be moved off the main
CentOS mirrors and placed on http://vault.centos.org/ where it will be
available for reference.

All users currently using CentOS-4 are advised to begin planning the
upgrade to CentOS-5 (EOL Date: March 31, 2014) or CentOS-6 (EOL Date:
November 30, 2017) ... or a move to the upstream ELS program for EL4.

This will be the 3rd enterprise Linux distribution that the CentOS
Project has taken to EOL, with CentOS-4.9 joining CentOS-3.9 and
CentOS-2.1 in the vault.
