[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).
