However, a handful of features *have* changed in ways that, for some users, will be
backwards-incompatible. The big changes are:
* Support for Python 2.3 has been dropped. See the full notes
below.
* The new CSRF protection framework is not backwards-compatible with
the old system. Users of the old system will not be affected until
the old system is removed in Django 1.4.

Python compatibility
====================
While not a new feature, it's important to note that Django 1.2
introduces the first shift in our Python compatibility policy since
Django's initial public debut. Previous Django releases were tested
and supported on 2.x Python versions from 2.3 up; Django 1.2, however,
drops official support for Python 2.3. As such, the minimum Python
version required for Django is now 2.4, and Django is tested and
supported on Python 2.4, 2.5 and 2.6, and will be supported on the
as-yet-unreleased Python 2.7.
This change should affect only a small number of Django users, as most
operating-system vendors today are shipping Python 2.4 or newer as
their default version. If you're still using Python 2.3, however,
you'll need to stick to Django 1.1 until you can upgrade; per
:ref:`our support policy <internals-release-process>`, Django 1.1 will
continue to receive security support until the release of Django 1.3.
A roadmap for Django's overall 2.x Python support, and eventual
transition to Python 3.x, is currently being developed, and will be
announced prior to the release of Django 1.3.
