The update adds the following:
New accessories (Skirts, Pink Latex socks, Blindfold, Frilly white strapless, Toe ring)
Wumpa mode is now always an option you can enable, not just stuck to variation 3
All 3 variations are now selectable from the opening game, when you start the action, you are presented with the 3 options
Desktop Buddy Info (Windows Only): This is experimental and may not work on all computers. Run the Desktop Buddy version to have bandicoot buddy sit on your desktop at all times (Set limit dialog in options so she stays quiet) and you can drag her around, keep her company with you while you work, and tap on her when you like. I'd really love feedback on this for anyone who tests this one out!

Current Codes:
'futa' - In the Credits Menu, Tab ‘Code Entry’. Enter ‘futa’ all lower case, and apply code (Code is saved to your saved game). Close the main menu and open it again, you’ll get a new button ‘Enable Codes’. Open it, and enable the futa checkbox whenever you want this toggled on.
