The headlines:-

1. Added new MUI.* material controls for premium users!

2. Complete revamp of the look and feel of the DS Android app to give it a more 
modern 'material' look and feel. 

3. New theme options available which allow whole app theming for light or dark 
mode using the following config switches:-

cfg.Dark, cfg.Light, cfg.Holo
	
This works for non-premium users too.  However theme customization and dynamic 
theme switching still requires premium.

4. Added a new 'Switch' control which provides a sliding toggle switch.

5. Added new 'Class' file template for adding classes to your apps.

6. Better support for ES6 in the obfuscator.


WARNING: THE NEW THEMES MAY BREAK YOUR OLD APPS, PUT cfg.Holo AT THE TOP 
OF YOUR OLD APPS TO MAINTAIN THEIR CURRENT LOOK.
