==========================
Django 2.2.4 release notes
==========================
*Expected August 1, 2019*
Django 2.2.4 fixes several bugs in 2.2.3.
Bugfixes
========
* Fixed a regression in Django 2.2 when ordering a ``QuerySet.union()``,
``intersection()``, or ``difference()`` by a field type present more than
once results in the wrong ordering being used (:ticket:`30628`).
* Fixed a migration crash on PostgreSQL when adding a check constraint
with a ``contains`` lookup on
:class:`~django.contrib.postgres.fields.DateRangeField` or
:class:`~django.contrib.postgres.fields.DateTimeRangeField`, if the right
hand side of an expression is the same type (:ticket:`30621`).
* Fixed a regression in Django 2.2 where auto-reloader crashes if a file path
contains nulls characters (``'\x00'``) (:ticket:`30506`).
