Major changes in this version of CentOS include:
1. Upgraded update system. The CentOS Project has designed a new
update system to deal with the issues that we had during the last CentOS
4 update cycle. This new system provides more that 100 total mirrors
for updates and picks geographically close and non-stale mirrors based
on our master server's content. It provides failover capability, so if
a mirror is unavailable another will be chosen. Combined with the
optional yum-plugin-fastestmirror, it will also pick the mirror that has
the fastest connection to your location.
The new update system uses yum only. Up2date will work for updates, but
does not provide any of the new functionality, therefore yum is the
recommended way for you to do CentOS updates.
To utilize the new update system with yum, you first need to update yum
and centos-yumconf to the latest versions. These updates were released
for CentOS 4 on February 16th (CEEA:2006:0216-001, centos-yumconf) and
February 20th (CEBA:2006:0220-001, yum), so you may already have them.
You can check to see if you have the new yum and centos-yumconf with
rpm -q yum centos-yumconf
If you have the below listed files, you are ready to use the new update
If you have earlier versions of either program, you should be able to
upgrade them with the command:
yum upgrade yum centos-yumconf
Note: If you have previously modified your /etc/yum.repos.d/CentOS-
Base.repo file, a file named /etc/yum.repos.d/CentOS-Base.repo.rpmnew
will be created. If you want to use the new update system, this file
should be copied to CentOS-Base.repo. An example of the new
default /etc/yum.repos.d/CentOS-Base.repo file should look like is
