It wasn’t removed. Version 7 was a complete rebuild not intended to be 100% backwards compatible. Features that users found difficult or unclear were reimagined or removed in favor of other solutions.
In this case, browser support for
object-fit: cover|contain is the suggest workaround. It’s not a one-for-one solution, but it removes the effort required from clients to properly crop an image.
I’ve tried to make version 7 as backwards compatible as possible, but early adopters will notice some differences like this throughout the app. If this causes friction, remaining on version 5 is a totally valid option too — support isn’t going away for it any time soon.
As more feedback comes in, I’ll be happy to revisit features such as this. However, until this thread, nobody has seemed to miss the ability to crop images (presumably because it wasn’t very discoverable in version 5).
