One of my chores is keeping track of rpm.org changes.

Today, a pre-existing tag was changed from an integer array
to an integer.

     http://devel.linux.duke.edu/gitweb/? 
p=rpm.git;a=commitdiff;h=05be2a2fdb44558d2b6bc1b785128c1decae2aae

Note "pre-existing". Changes to pre-existing tags will create
RPM package incompatibilities in the future.

If deliberate incompatibilities are the goal, fine. But I see to  
recall a promise from
rpm.org to keep at least the tag space identical with same numbers &  
types.

And -- as usual -- no credit whatsoever for the prior implementation  
@rpm5.org,
clear plagarism is involved, even to identical variable names.
