Comment:

 7.10.3 is a minor release before the quite major 8.0 and consequently we
 are trying to keep the delta small. This desire, coupled with the fact
 that Cabal can be easily updated after installation, convinced me that the
 potential risk that a bump (which involves more than 20k lines of changes)
 would carry outweighs the relatively minor benefits. Sorry!
