Django 1.5 release notes - UNDER DEVELOPMENT
|
|
============================================
|
|
|
|
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 1.4 or older versions. We've also dropped some
|
|
features, which are detailed in :doc:`our deprecation plan
|
|
</internals/deprecation>`, and we've `begun the deprecation process for some
|
|
features`_.

|
|
.. _`backwards incompatible changes`: `Backwards incompatible changes in 1.5`_
|
|
.. _`begun the deprecation process for some features`: `Features deprecated in 1.5`_
|
|
|
|
Python compatibility
|
|
====================
|
|
|
|
Django 1.5 has dropped support for Python 2.5. Python 2.6 is now the minimum
|
|
required Python version. Django is tested and supported on Python 2.6 and
|
|
2.7.
|
|
|
|
This change should affect only a small number of Django users, as most
|
|
operating-system vendors today are shipping Python 2.6 or newer as their default
|
|
version. If you're still using Python 2.5, however, you'll need to stick to
|
|
Django 1.4 until you can upgrade. Per :doc:`our support policy
|
|
</internals/release-process>`, Django 1.4 will continue to receive security
|
|
support until the release of Django 1.6.
|
|
|
|
As Jython does currently not offer any version compatible with Python 2.6,
|
|
Django 1.5 does not run on Jython.
|
|
|
|
What's new in Django 1.5
|
|
========================
|
|
|
|
Minor features
|
|
~~~~~~~~~~~~~~
|
|
|
|
Django 1.5 also includes several smaller improvements worth noting:
|
|
|
|
* The template engine now interprets ``True``, ``False`` and ``None`` as the
|
|
corresponding Python objects.
|
|
|
|
* :mod:`django.utils.timezone` provides a helper for converting aware
|
|
datetimes between time zones, see :func:`~django.utils.timezone.localtime`.
|
|
|
|
Backwards incompatible changes in 1.5
|
|
=====================================
|
|
|
|
.. warning::
|
|
|
|
In addition to the changes outlined in this section, be sure to review the
|
|
:doc:`deprecation plan </internals/deprecation>` for any features that
|
|
have been removed. If you have not updated your code within the
|
|
deprecation timeline for a given feature, its removal may appear as a
|
|
backwards incompatible change.
|
|
|
|
Features deprecated in 1.5
|
|
==========================
|
|
|
|
itercompat.product
|
|
~~~~~~~~~~~~~~~~~~
|
|
|
|
The :func:`~django.utils.itercompat.product` function has been deprecated. Use
|
|
the builtin `itertools.product` instead.
