[Fedora-packaging] Where Can I Find Previous Versions?

[Joseph D. Wagner]

I've noticed that mirrors no longer appear to contain previous versions 
of packages.  For example, when kernel-3.4.3 was released, kernel-3.4.2 
disappeared from all the mirrors.

I recently had regression troubles, and I wanted to downgrade to a 
previous version to resolve the issue.  However, I was surprised to find 
the previous version was gone.  My only option was to downgrade to the 
original version that came with the distribution.  I was very 
disappointed with that.

Is there some place I can find the previous version?  If not, is it 
possible to change this so at least 1 previous version is left in the 
mirrors?
