Django 1.10 release notes - UNDER DEVELOPMENT
=============================================

Welcome to Django 1.10!

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
1.9 or older versions. We've :ref:`dropped some features<removed-features-1.10>`
that have reached the end of their deprecation cycle, and we've `begun the
deprecation process for some features`_.

.. _`dropped some features`: `Features removed in 1.10`_
.. _`begun the deprecation process for some features`: `Features deprecated in 1.10`_

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

Like Django 1.9, Django 1.10 requires Python 2.7, 3.4, or 3.5. We **highly
recommend** and only officially support the latest release of each series.

Backwards incompatible changes in 1.10
======================================

.. warning::

    In addition to the changes outlined in this section, be sure to review the
    :ref:`removed-features-1.10` for the features that have reached the end of
    their deprecation cycle and therefore 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.

  :meth:`~django.template.backends.base.Template.render()` method.
