Ability to move tracks in multitrack by right clicking and dragging on track controls Just right click in the track controls and drag up and down to reposition entire tracks in the multitrack view.

Faster response in VU meters and Frequency and Phase Analysis windows

Multichannel WAV import and export
You can now import WAV files with more than 2 channels as a series of mono WAVs. This enables you to open a WAV file that contains a 5.1 surround mix, edit each of the wave files, and re-save the tracks as a multichannel wave file using the multichannel encoder."
