Is the only difference between version 1.3.679 and .681 in that .681 includes vstgui3? I'm on Windows and use Pro Tools and Reaper, so that wouldn't affect me at all. If that is really the only difference, I'm not going to bother to upgrade from .679, which is working just fine for me so far.
Just a general suggestion, release notes would be really helpful to answer questions like this. I know they are a pain to produce, but they don't have to be extensive. A couple bullets or even one sentence explaining the differences in versions would be very informative.
