While HES/FPS/Barco Entertainment Lighting Controllers, Inc. does keep an extensive database of enhancements/bugs (squashed or otherwise), it is their policy not to make this list public for obvious competitive and PR reasons.
As was mentioned here and here, the best way to keep up with squashed bugs is to pay close attention to the release notes of each software version. The gents in Austin are always very forthcoming when we need information on a specific bug. If you know it's been mentioned on the forum before, it's easiest to reference the enhancement number so that Brad, Tom, and the rest of the team can respond easily.
Also, when submitting a bug (whether you believe it is as-yet-unknown or simply a persistent little critter), it is incredibly helpful to the developers if you can report it according to the guidelines here.
As Phil said we do not publish that information for the public, but feel free to contact me or other HES staff at any time with any questions you might have.
