Django 1.9 release notes - UNDER DEVELOPMENT
============================================

Welcome to Django 1.9!

These release notes cover the `new features`_, as well as some `backwards
incompatible changes`_ you'll want to be aware of when upgrading from Django
1.8 or older versions. We've :ref:`dropped some features
<deprecation-removed-in-1.9>` that have reached the end of their deprecation
cycle, and we've `begun the deprecation process for some features`_.

.. _`new features`: `What's new in Django 1.9`_
.. _`backwards incompatible changes`: `Backwards incompatible changes in 1.9`_
.. _`dropped some features`: `Features removed in 1.9`_
.. _`begun the deprecation process for some features`: `Features deprecated in 1.9`_

Python compatibility
====================

Like Django 1.8, Django 1.9 requires Python 2.7 or above, though we
**highly recommend** the latest minor release. We've dropped support for
Python 3.2 and added support for Python 3.5.

.. warning::

    In addition to the changes outlined in this section, be sure to review the
    :doc:`deprecation timeline </internals/deprecation>` for any features that
    have been removed. If you haven't updated your code within the
    deprecation timeline for a given feature, its removal may appear as a
    backwards incompatible change.

These features have reached the end of their deprecation cycle and so have been
