Changes 1.11.1:

Allowed disabling server-side cursors on PostgreSQL

Made migrations respect Index’s name argument. If you created a named index \ 
with Django 1.11, makemigrations will create a migration to recreate the index \ 
with the correct name.
Fixed a crash when using a __icontains lookup on a ArrayField.
Fixed a crash when using a two-tuple in EmailMessage’s attachments argument.
Fixed QuerySet.filter() crash when it references the name of a OneToOneField \ 
primary key.
Fixed empty POST data table appearing instead of “No POST data” in \ 
HTML debug page.
Restored BoundFields without any choices evaluating to True.
Prevented SessionBase.cycle_key() from losing session data if _session_cache \ 
isn’t populated.
Fixed layout of ReadOnlyPasswordHashWidget (used in the admin’s user change \ 
page).
Allowed prefetch calls on managers with custom ModelIterable subclasses.
Fixed change password link in the contrib.auth admin for el, es_MX, and pt \ 
translations.
Restored the output of the class attribute in the <ul> of widgets that use \ 
the multiple_input.html template. This fixes ModelAdmin.radio_fields with \ 
admin.HORIZONTAL.
Fixed crash in BaseGeometryWidget.subwidgets().
Fixed exception reraising in ORM query execution when cursor.execute() fails and \ 
the subsequent cursor.close() also fails.
Fixed a regression where CheckboxSelectMultiple, NullBooleanSelect, RadioSelect, \ 
SelectMultiple, and Select localized option values.
Corrected the stack level of unordered queryset pagination warnings.
Fixed a regression causing incorrect queries for __in subquery lookups when \ 
models use ForeignKey.to_field.

Fixed a regression in formset min_num validation with unchanged forms that have \ 
initial data.
Prepared for cx_Oracle 6.0 support.

Fixed crash in BaseGeometryWidget.get_context() when overriding existing attrs.
Prevented AddIndex and RemoveIndex from mutating model state.
Prevented migrations from dropping database indexes from Meta.indexes when \ 
changing Field.db_index to False.
Fixed a regression in choice ordering in form fields with grouped and \ 
non-grouped options.

multi-table inheritance parent models after saving a child model.
Corrected the return type of ArrayField(CITextField()) values retrieved from the \ 
database.
Fixed QuerySet.prefetch_related() crash when fetching relations in nested \ 
Prefetch objects.
Prevented hiding GDAL errors if it’s not installed when using contrib.gis. \ 
(It’s a required dependency as of Django 1.11.)

foreign key’s parent model as the lookup
