==========================
Django 2.2.7 release notes
==========================
*Expected November 1, 2019*
Django 2.2.7 fixes several bugs in 2.2.6.
Bugfixes
========
* Fixed a crash when using a ``contains``, ``contained_by``, ``has_key``,
``has_keys``, or ``has_any_keys`` lookup on
:class:`~django.contrib.postgres.fields.JSONField`, if the right or left hand
side of an expression is a key transform (:ticket:`30826`).
* Prevented :option:`migrate --plan` from showing that ``RunPython`` operations
are irreversible when ``reverse_code`` callables don't have docstrings or
when showing a forward migration plan (:ticket:`30870`).
