For the record, Enterprise Linux distributions do not normally switch
major server versions during the lifetime of the distribution.  This is
ACTUALLY the whole reason ENTERPRISE distros exist.

Backporting of security and bug fixes is done to make the released
version more stable and more secure over the lifetime of the distro so
that custom software that you pay to be written does not become obsolete
with an API/ABI change of a component.

See this link about backporting by Red Hat:


So, for almost any server related services (IPA, LDAP, EMail, httpd,
samba, etc., etc., ... ), there will likely not be an upgrade of the
service within the main distribution.

CentOS-6 will most likely always have httpd version 2.2.15-XX (where XX
will change, but not 2.2.15).  CentOS-7  will have version 2.4.6-XX of

If you want server services always moving to the latest and greatest,
CentOS is the distribution you are looking for.  That is Fedora (if you
want a Red Hat family equivalent).
