- @unsupported now only accepts a single target and demands a reason for not running the test. - @exclude also demands an exclusion reason - Greatly expanded @testing.requires.<feature>, eliminating many decorators in the suite and signficantly easing integration of multi-driver support. - New ORM test base class, and a featureful base for mapped tests - Usage of 'global' for shared setup going away, * imports as well
