Django 3.0.7 release notes
==========================
*Expected June 1, 2020*
Django 3.0.7 fixes several bugs in 3.0.6.
Bugfixes
========
Fixed #31538 -- Fixed Meta.ordering validation lookups that are not transforms. Regression in 440505cb2cadbe1a5b9fba246bcde6c04f51d07e. Thanks Simon Meers for the report.

* Fixed a regression in Django 3.0 by restoring the ability to use field
lookups in ``Meta.ordering`` (:ticket:`31538`).
Fixed #31566 -- Fixed aliases crash when chaining values()/values_list() after annotate() with aggregations and subqueries. Subquery annotation references must be resolved if they are excluded from the GROUP BY clause by a following .values() call. Regression in fb3f034f1c63160c0ff13c609acd01c18be12f80. Thanks Makina Corpus for the report.

* Fixed a regression in Django 3.0 where ``QuerySet.values()`` and
``values_list()`` crashed if a queryset contained an aggregation and a
subquery annotation (:ticket:`31566`).
Fixed #31568 -- Fixed alias reference when aggregating over multiple subqueries. 691def10a0197d83d2d108bd9043b0916d0f09b4 made all Subquery() instances equal to each other which broke aggregation subquery pushdown which relied on object equality to determine which alias it should select. Subquery.__eq__() will be fixed in an another commit but Query.rewrite_cols() should haved used object identity from the start. Refs #30727, #30188. Thanks Makina Corpus for the report.

* Fixed a regression in Django 3.0 where aggregates used wrong annotations when
a queryset has multiple subqueries annotations (:ticket:`31568`).
Fixed #31584 -- Fixed crash when chaining values()/values_list() after Exists() annotation and aggregation on Oracle. Oracle requires the EXISTS expression to be wrapped in a CASE WHEN in the GROUP BY clause. Regression in efa1908f662c19038a944129c81462485c4a9fe8.
