Django 2.2 release notes - UNDER DEVELOPMENT
|
|
============================================
|
|
|
|
*Expected April 2019*
|
|
|
|
Welcome to Django 2.2!
|
|
|
|
These release notes cover the :ref:`new features <whats-new-2.2>`, as well as
|
|
some :ref:`backwards incompatible changes <backwards-incompatible-2.2>` you'll
|
|
want to be aware of when upgrading from Django 2.1 or earlier. We've
|
|
:ref:`begun the deprecation process for some features
|
|
<deprecated-features-2.2>`.
|
|
|
|
See the :doc:`/howto/upgrade-version` guide if you're updating an existing
|
|
project.
|
|
|
|
Django 2.2 is designated as a :term:`long-term support release`. It will
|
|
receive security updates for at least three years after its release. Support
|
|
for the previous LTS, Django 1.11, will end in April 2020.
|
|
|
|
Python compatibility
|
|
====================
|
|
|
|
Django 2.2 supports Python 3.5, 3.6, and 3.7. We **highly recommend** and only
|
|
officially support the latest release of each series.
