The newest build (build 3) of our stereo plugins has just been posted. There are only a few visible changes from build 2, but there's more under the hood. All you need to use them is a license.
Find out all about it at the Beta Download Page. We got new betas for PhoenixVerb, R2, M7Control, Excalibur, NIMBUS and R4. We'll have updated betas for the surround plugins in a week or two.
These changes have been underway in-house for a while, but now we need the help of the larger Exponential Audio community. If you've got a little time, your help is appreciated.
