:doc:`The release of Django 1.0 </releases/1.0>` comes with a promise of API
stability and forwards-compatibility. In a nutshell, this means that code you
-develop against Django 1.0 will continue to work against 1.1 unchanged, and you
-should need to make only minor changes for any 1.X release.

What "stable" means
===================
In this context, stable means:
-- All the public APIs -- everything documented in the linked documents below,
- and all methods that don't begin with an underscore -- will not be moved or
- renamed without providing backwards-compatible aliases.

they will not break or change the meaning of existing methods. In other

-- :doc:`Templates </topics/templates>`, including the language, Python-level
- :doc:`template APIs </ref/templates/index>`, and :doc:`custom template tags
- and libraries </howto/custom-template-tags>`. We may add new template
- tags in the future and the names may inadvertently clash with
- external template tags. Before adding any such tags, we'll ensure that
- Django raises an error if it tries to load tags with duplicate names.

-However, any changes to contrib apps will come with an important guarantee:
-we'll make sure it's always possible to use an older version of a contrib app if
