Django 2.0.5 release notes

Django 2.0.5 fixes several bugs in 2.0.4.

• 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 ().
• Fixed a regression in Django 2.0.4 where QuerySet.values() or values_list() after combining an annotated and unannotated queryset with , difference(), or intersection() crashed due to mismatching columns (#29286).
