In the environment we are in, regression testing implies more than just making
sure bug fixes are carried into new levels. It implies that new levels of the
EXEC and layered products with their new features (and changes to existing
features) do not cause programs and configurations which currently work to stop
workings [unless it has been explicitly documented that a user will observe the
effect]. Although your definition is probably how things started out, this
definition seems to be the current state of the term. {At least for a Unisys
1100/2200 software environment.}
