Most notably in this version is a Preamp control. Sometimes when you filter out some frequencies with the equalizer, the overall signal level goes down. Of course you can move up all the sliders to recover some power but now you only have to move the Preamp level up. There is also a level indicator to give you a hint of how much you can push up before getting distortion.
This version also includes some fixes for the Windows platform. Some users reported that the note analyzer was flickering, and sometimes the wave view too. Now the flicker should have gone on those views. There is still some issues on the sliders but they will be fixed in the next version.
