May 1, 2018

Django 1.11.13 fixes several bugs in 1.11.12.

## Poprawki błędów

- Fixed a regression in Django 1.11.8 where altering a field with a unique constraint may drop and rebuild more foreign keys than necessary (#29193).

- Fixed crashes in `django.contrib.admindocs` when a view is a callable object, such as `django.contrib.syndication.views.Feed` (#29296).

- Fixed a regression in Django 1.11.12 where `QuerySet.values()` or `values_list()` after combining an annotated and unannotated queryset with `union()`, `difference()`, or `intersection()` crashed due to mismatching columns (#29286).
