Nothing has changed in the Aurora layout except for the theme-package.
Start a new app, choose the aurora layout and deploy. Go to your project explorer and open the theme folder. Copy the theme package into your existent app.
If you already made changes to your custom theme I would suggest comparing the different theme packages. The structure on how to build a theme package has changed a little and some classes have different names.
