Quoi de neuf dans la dernière version ?

This update from Apple will improve the functionality of this app. No new features are included.

Photo saving failure was showing an unhelpful "Data unavailable" error when the user didn't grant the app access to the Photo Library.
Now the app will present a detailed message about how to enable the required permissions to be able to save photos.
