Source for freeradius-server-2.0.4

[Charles H. Fisher]

I have  heavily patched version of freeradius-server-2.0.4 That I would 
like to migrate forward to the current version. This requires that I 
know what changes were made to the standard 2.0.4. I have not been able 
to find a copy of it on the internet, and the archives on this site do 
not have any of older files any later than the end of the 1.x series. Do 
you know where I can find a copy of the freeradius-server-2.0.4 source 
tarball.

Thanks
