# Django 1.11.4 release notes

*August 1, 2017*

Django 1.11.4 fixes several bugs in 1.11.3.

## Bugfixes

- Fixed a regression in 1.11.3 on Python 2 where non-ASCII `format` values
  for date/time widgets results in an empty `value` in the widget’s HTML
  ([#28355](https://code.djangoproject.com/ticket/28355)).
- Fixed `QuerySet.union()` and `difference()` when combining with
  a queryset raising `EmptyResultSet` ([#28378](https://code.djangoproject.com/ticket/28378)).
- Fixed a regression in pickling of `LazyObject` on Python 2 when the wrapped
  object doesn’t have `__reduce__()` ([#28389](https://code.djangoproject.com/ticket/28389)).
- Fixed crash in `runserver`’s `autoreload` with Python 2 on Windows with
  non-`str` environment variables ([#28174](https://code.djangoproject.com/ticket/28174)).
- Corrected `Field.has_changed()` to return `False` for disabled form
  fields: `BooleanField`, `MultipleChoiceField`, `MultiValueField`,
  `FileField`, `ModelChoiceField`, and `ModelMultipleChoiceField`.
- Fixed `QuerySet.count()` for `union()`, `difference()`, and
  `intersection()` queries. ([#28399](https://code.djangoproject.com/ticket/28399)).
- Fixed `ClearableFileInput` rendering as a subwidget of `MultiWidget`
  ([#28414](https://code.djangoproject.com/ticket/28414)). Custom `clearable_file_input.html` widget templates
  will need to adapt for the fact that context values
  `checkbox_name`, `checkbox_id`, `is_initial`, `input_text`,
  `initial_text`, and `clear_checkbox_label` are now attributes of
  `widget` rather than appearing in the top-level context.
- Fixed queryset crash when using a `GenericRelation` to a proxy model
  ([#28418](https://code.djangoproject.com/ticket/28418)).
