Django 2.0 release notes - UNDER DEVELOPMENT
|
|
|
|
|
============================================
|
|
|
|
|
|
|
|
|
|
Welcome to Django 2.0!
|
|
|
|
|
|
|
|
|
|
These release notes cover the :ref:`new features <whats-new-2.0>`, as well as
|
|
|
|
|
some :ref:`backwards incompatible changes <backwards-incompatible-2.0>` you'll
|
|
|
|
|
want to be aware of when upgrading from Django 1.11 or earlier. We've
|
|
|
|
|
:ref:`dropped some features<removed-features-2.0>` that have reached the end of
|
|
|
|
|
their deprecation cycle, and we've :ref:`begun the deprecation process for some
|
|
|
|
|
features <deprecated-features-2.0>`.
|
|
|
|
|
|
|
|
|
|
See the :doc:`/howto/upgrade-version` guide if you're updating an existing
|
|
|
|
|
project.
|
|
|
|
|
|
|
|
|
|
Python compatibility
|
|
|
|
|
====================
|
|
|
|
|
|
|
|
|
|
Django 2.0 supports Python 3.5+. Since Django 1.11, support for Python 2.7 and
|
|
|
|
|
3.4 is removed. We **highly recommend** and only officially support the latest
|
|
|
|
|
release of each series.
|
|
|
|
|
|
|
|
|
|
Third-party library support for older version of Django
|
|
|
|
|
=======================================================
|
|
|
|
|
|
|
|
|
|
Following the release of Django 2.0, we suggest that third-party app authors
|
|
|
|
|
drop support for all versions of Django prior to 1.11. At that time, you should
|
|
|
|
|
be able run your package's tests using ``python -Wd`` so that deprecation
|
|
|
|
|
warnings do appear. After making the deprecation warning fixes, your app should
|
|
|
|
|
be compatible with Django 2.0.
