[CentOS] FreeRadius version

It seems to me that the ver of FreeRadius is 1.0.1:

yum list | grep "radius"
freeradius.i386                          1.0.1-3.RHEL4 
installed
freeradius-mysql.i386                    1.0.1-3.RHEL4          base 

freeradius-postgresql.i386               1.0.1-3.RHEL4          base 

freeradius-unixODBC.i386                 1.0.1-3.RHEL4          base

According to freeradius.org, this was released 8/17/04 and 1.1.0 was 
released 1/12/06

Why is the distributed version so far behind?

Also I am trying to figure out how to get dialup_admin working.  I 
cannot find any reference to it, how to get it working within Apache 
and access it....

(Hopefully Alan is here at IETF, and can help me).
