Here are the things you need to know:

• Next step and previous step actions are now available as action types in the object properties. This allows for a much easier setup when using 3D spatial objects for step navigation.
  

• Added HDR environments for Create and the app, to allow you to visualize material properties more correctly.
  
  
  
• Added possibility to delete projects from the welcome screen.
