Django 1.11.4 release notes
===========================

*Under development*

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
  (:ticket:`28355`).

* Fixed ``QuerySet.union()`` and ``difference()`` when combining with
  a queryset raising ``EmptyResultSet`` (:ticket:`28378`).

* Fixed a regression in pickling of ``LazyObject`` on Python 2 when the wrapped
  object doesn't have ``__reduce__()`` (:ticket:`28389`).

* Fixed crash in ``runserver``'s ``autoreload`` with Python 2 on Windows with
  non-``str`` environment variables (: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. (:ticket:`28399`).

* Fixed ``ClearableFileInput`` rendering as a subwidget of ``MultiWidget``
  (: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.
