With the introduction of the File field for forms, you can now directly attach images to new records on mobile (and web too, of course). This means that you can easily create, for example, an Expense Reports app, where you attach a picture of the receipt along side other information.
Other than that, user permissions are now reflected in the UI – if the end user does not have appropriate permissions, the remove/edit/add options are hidden.
There's also multiple other bugfixes – read below for details!
