No more unexpected results when a clip contains alpha. You can now use any blend as a transition between clips and it will always fade smoothly from clip A to clip B. Subtract, Difference and Difference I (inverse) have been improved and now look exactly the same as in Photoshop. New in this release are Dissolve, Exclusion and Overlay blend modes and there are a few new '50' blends like 50 Dodge and 50 Burn.
