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`_.

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.

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
|
|
removed in Django 1.9 (please see the :ref:`deprecation timeline
