Updating a Core Data application

[qPaul]

Hello!
I'm developing an app with Core Data. Now when I add an entity to Core Data and start my app, the app crashes. It's because I added a new entity.
So, that's a problem when I sell my app in the App Store and in the next update I have one new entity, how can I update the app without loosing all saved data?
Thanks in advance!
