Version 6.0.0

changed the ngModel behaviour for single file select.

Migration notes:

• ng-model behaves differently now and could break the code written for previous versions.
  Since this version the model value will be a single file instead of an array if all of the followings are true:
  • ngf-multiple is not set or is resolved to false.
  • multiple attribute is not set on the element
  • ngf-keep is not set or set to false.

Otherwise ng-model will set the model value to an array of files like previous versions.

To facilitate the backward compatibility you can use ngf-model instead of ng-model which will have the same behaviour as previous ng-model except that combining with ng-required will not work.
