Description: 

The flag object property $flag->content_type has been renamed $flag->entity_type.

(Note that while, technically, flags can be applied to any object that is identified with a string for its 'type' and a number for its id. However, the vast majority of cases will involve flagging entities. So while 'object' is technically correct, 'entity' is a better fit and better DX in 90% of cases.
