How compatible with 7.0 and 7.1 be from an application standpoint?
Will applications linked with libraries from 7.0 be able to talk to
the 7.1 database?  Any changes in library major versions? The other
way? 

The reason I'm asking is that Red Hat wants to maintain binary
compatibility in a for all x in y.x (that's what distribution
numbering means to us, other Linux distributions have other (and
sometimes rather weird) schemes), but I'm also interested in upgrading
the database component.
