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.

.. _backwards-incompatible-2.1:
|
|
|
|
Backwards incompatible changes in 2.1
|
|
=====================================
|
|
|
|
Database backend API
|
|
--------------------
|
|
|
|
* To adhere to :pep:`249`, exceptions where a database doesn't support a
|
|
feature are changed from :exc:`NotImplementedError` to
|
|
:exc:`django.db.NotSupportedError`.
|
|
|
|
:mod:`django.contrib.gis`
|
|
-------------------------
|
|
|
|
* Support for SpatiaLite 4.0 is removed.
|
|
|
|
Dropped support for MySQL 5.5
|
|
-----------------------------
|
|
|
|
The end of upstream support for MySQL 5.5 is December 2018. Django 2.1 supports
|
|
MySQL 5.6 and higher.
|
|
|
|
Dropped support for PostgreSQL 9.3
|
|
----------------------------------
|
|
|
|
The end of upstream support for PostgreSQL 9.3 is September 2018. Django 2.1
|
|
supports PostgreSQL 9.4 and higher.
|
|
|
|
Miscellaneous
|
|
-------------
|
|
|
|
* The minimum supported version of ``mysqlclient`` is increased from 1.3.3 to
|
|
1.3.7.
|
|
|
|
* The date format of ``Set-Cookie``'s ``Expires`` directive is changed to
|
|
follow :rfc:`7231#section-7.1.1.1` instead of Netscape's cookie standard.
|
|
Hyphens present in dates like ``Tue, 25-Dec-2018 22:26:13 GMT`` are removed.
|
|
This change should be merely cosmetic except perhaps for antiquated browsers
|
|
that don't parse the new format.
|
|
|
|
* ``allowed_hosts`` is now a required argument of private API
|
|
``django.utils.http.is_safe_url()``.
|
|
|
|
* The ``multiple`` attribute rendered by the
|
|
:class:`~django.forms.SelectMultiple` widget now uses HTML5 boolean syntax
|
|
rather than XHTML's ``mulitple="multiple"``.
|
|
|
|
.. _deprecated-features-2.1:
|
|
|
|
Features deprecated in 2.1
|
|
==========================
|
|
|
|
Miscellaneous
|
|
-------------
|
|
|
|
* The ``ForceRHR`` GIS function is deprecated in favor of the new
|
|
:class:`~django.contrib.gis.db.models.functions.ForcePolygonCW` function.
|
|
|
|
* ``django.utils.http.cookie_date()`` is deprecated in favor of
|
|
:func:`~django.utils.http.http_date`, which follows the format of the latest
|
|
RFC.

|
