* Wagtail's middleware classes are now compatible with Django 1.10's `new-style middleware <https://docs.djangoproject.com/en/1.10/releases/1.10/#new-style-middleware>`_ (Karl Hobley)
* Fixed regression on Django 1.10.1 causing Page subclasses to fail to use PageManager (Matt Westcott)
Upgrade considerations
======================
Multi-level inheritance and custom managers
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The inheritance rules for :ref:`custom_page_managers` have been updated to match Django's standard behaviour. In the vast majority of scenarios there will be no change. However, in the specific case where a page model with a custom ``objects`` manager is subclassed further, the subclass will be assigned a plain ``Manager`` instead of a ``PageManager``, and will now need to explicitly override this with a ``PageManager`` to function correctly:
..code-block:: python
class EventPage(Page):
objects = EventManager()
class SpecialEventPage(EventPage):
# Previously SpecialEventPage.objects would be set to a PageManager automatically;
