Django 1.8.6 adds official support for Python 3.5 and fixes several bugs in 1.8.5:
Fixed a regression causing ModelChoiceField to ignore prefetch_related() on its \ 
queryset.
Allowed “mode=memory” in SQLite test database name if supported.
Fixed system check crash on ForeignKey to abstract model.
Fixed incorrect queries when you have multiple ManyToManyFields on different \ 
models that have the same field name, point to the same model, and have their \ 
reverse relations disabled.
Allowed filtering over a RawSQL annotation.
Made the Concat database function idempotent on SQLite.
Avoided a confusing stack trace when starting runserver with an invalid \ 
INSTALLED_APPS setting.
Made deferred models use their proxied model’s _meta.apps for caching and \ 
retrieval. This prevents any models generated in data migrations using \ 
QuerySet.defer() from leaking to test and application code.
Fixed a typo in the name of the strictly_above PostGIS lookup.
Fixed crash with contrib.postgres.forms.SplitArrayField and IntegerField on \ 
invalid value.
Added a helpful error message when Django and South migrations exist in the same \ 
directory.
Fixed a regression in URLValidator that allowed URLs with consecutive dots in \ 
the domain section (like http://example..com/) to pass.
Fixed a crash with GenericRelation and BaseModelAdmin.to_field_allowed.
