Django 2.2.1 release notes
==========================
*Expected May 1, 2019*
Django 2.2.1 fixes several bugs in 2.2.
Bugfixes
========
* Fixed a regression in Django 2.1 that caused the incorrect quoting of
database user password when using :djadmin:`dbshell` on Oracle
(:ticket:`30307`).
* Added compatibility for ``psycopg2`` 2.8 (:ticket:`30331`).
* Fixed a regression in Django 2.2 that caused a crash when loading the
template for the technical 500 debug page (:ticket:`30324`).
* Fixed crash of ``ordering`` argument in
:class:`~django.contrib.postgres.aggregates.ArrayAgg` and
:class:`~django.contrib.postgres.aggregates.StringAgg` when it contains an
expression with params (:ticket:`30332`).
* Fixed a regression in Django 2.2 that caused a single instance fast-delete
to not set the primary key to ``None`` (:ticket:`30330`).
* Prevented :djadmin:`makemigrations` from generating infinite migrations for
check constraints and partial indexes when ``condition`` contains
a :class:`~python:range` object (:ticket:`30350`).
* Reverted an optimization in Django 2.2 (:ticket:`29725`) that caused the
inconsistent behavior of ``count()`` and ``exists()`` on a reverse
many-to-many relationship with a custom manager (:ticket:`30325`).
* Fixed a regression in Django 2.2 where
:class:`~django.core.paginator.Paginator` crashed when ``object_list`` was
a queryset ordered or aggregated over a nested ``JSONField`` key transform
(:ticket:`30335`).
