This version of VoiceAttack was more about stuff on the inside than on the outside. What you'll find at the top of the list in this latest revision is improved performance for loading and saving profiles (especially those with extremely large profiles and/or profile sets).
There's a whole bunch of minor updates and fixes this time, so, for the complete list of what's new, make sure to check out the VoiceAttack change log here: http://www.voiceattack.com/changes
