Django 2.1 release notes - UNDER DEVELOPMENT
|
|
|
|
|
============================================
|
|
|
|
|
|
|
|
|
|
Welcome to Django 2.1!
|
|
|
|
|
|
|
|
|
|
These release notes cover the :ref:`new features <whats-new-2.1>`, as well as
|
|
|
|
|
some :ref:`backwards incompatible changes <backwards-incompatible-2.1>` you'll
|
|
|
|
|
want to be aware of when upgrading from Django 2.0 or earlier. We've
|
|
|
|
|
:ref:`dropped some features<removed-features-2.1>` that have reached the end of
|
|
|
|
|
their deprecation cycle, and we've :ref:`begun the deprecation process for some
|
|
|
|
|
features <deprecated-features-2.1>`.
|
|
|
|
|
|
|
|
|
|
See the :doc:`/howto/upgrade-version` guide if you're updating an existing
|
|
|
|
|
project.

|
|
|
Python compatibility
|
|
|
|
|
====================
|
|
|
|
|
|
|
|
|
|
Django 2.1 supports Python 3.5, 3.6, and 3.7. Django 2.0 is the last version to
|
|
|
|
|
support Python 3.4. We **highly recommend** and only officially support the
|
|
|
|
|
latest release of each series.
