Opalvision
ADpro 2.1.5 is the currently shipping product (and has been stable for a
good long time). The upgrade from 2.1.3 to 2.1.5 is free but contains only
some small bug fixes. I would recommend not going to the effort of
requesting 2.1.5 since 2.2.X will be released *very* shortly. This upgrade
will cost less than $50.
There is an OpalVision saver, and and OpalVision operator. Both of these
are provided by Centaur and will be provided on the 2.2.X upgrade.
