In the particular example you quoted, it did certainly mean more than 
minimal updates.

Minimal updates:
  - the FC1 src.rpm, or if FC1 published a security update, that 
src.rpm
  - *any* further change to the package, unless it would be covered by 
the security update is a non-minimal update.

In this particular case, zlib was upgraded from 1.2.0.7 to 1.2.1.2. 
The change log for comparison for this is below *). This update 
removed the need to apply the security patch, and removed an 
additional patch as well.

For example, Red Hat folks might, for some reason, update packages
in all of their archs (FC1..FC3) even though FC1 is no longer being 
updated -- which would be a clear non-minimal update.  Bugfixes might 
also be put in all the releases at the same time.

We can debate whether these non-minimal updates are significant enough 
to worry about, and we can debate whether we need to care (in QA 
sense) -- at least in the same manner as with RHL9/RHL73 as Fedora 
Core users are more likely intentional "guinea pigs" in any case -- if 
Red Hat's changes break the users' systems in some way.
