 My model has this field
 {{{
 starred_only = models.BooleanField(default=False)
 }}}

 Overriden in the ModelForm
 {{{
 starred_only = forms.BooleanField(required=False)
 }}}

 Django 1.10 stopped saving the unchecked (False) value. 1.10.1 started
 doing it again, and from 1.10.2 it stopped.

 This fixed it: https://github.com/django/django/pull/7068
 And this broke it: https://github.com/django/django/pull/7217

 I tried creating a custom widget:

 {{{
 class WorkingCheckboxInput(CheckboxInput):
     def value_omitted_from_data(self, data, files, name):
         return True
 }}}

 but value_omitted_from_data is never called.

 The docs and/or minor release changelogs doesn't really document how to
 get the previous default behavior back.
