The update form says at the bottom left: "New in this update" If you click on it, you get a list of the changes
Here is an extract from the text:
SOUND FORGE PRO 14 Build 130: ⦁ ARA - ARA plug-ins work synchronized with the destructive processing in Edit and Event Mode - Backend improvements - event management, undo/redo/ui handling - Bugfixes ⦁ More MP3 mono export options ⦁ DSD handling improvements ⦁ Marker names for scripting fixed (this bug came with Patch 3 - build 111) ⦁ Textured background fixed ⦁ Visualization files reset while program start with STRG + SHIFT keys
So it's true? Magix is forcing us SF 13 users to upgrade to SF 14 in order to get our legacy textured background? I didn't get any such new build notice.
