Add roadmap and contributing boilerplate to 1.3 alpha notes.

redundancy, :class:`~django.test.simple.DjangoTestRunner` has been

turned into an empty placeholder class, and will be removed entirely

in Django 1.5.

The Django 1.3 roadmap

======================

Before the final Django 1.3 release, several other preview/development

releases will be made available. The current schedule consists of at

least the following:

* Week of **November 29, 2010**: First Django 1.3 beta release. Final

  feature freeze for Django 1.3.

* Week of **January 10, 2011**: First Django 1.3 release

  candidate. String freeze for translations.

* Week of **January 17, 2011**: Django 1.3 final release.

If necessary, additional alpha, beta or release-candidate packages

will be issued prior to the final 1.3 release. Django 1.3 will be

released approximately one week after the final release candidate.

What you can do to help

=======================

In order to provide a high-quality 1.3 release, we need your help. Although this

alpha release is, again, *not* intended for production use, you can help the

Django team by trying out the alpha codebase in a safe test environment and

reporting any bugs or issues you encounter. The Django ticket tracker is the

central place to search for open issues:

    * http://code.djangoproject.com/timeline

Please open new tickets if no existing ticket corresponds to a problem you're

running into.

Additionally, discussion of Django development, including progress toward the

1.3 release, takes place daily on the django-developers mailing list:

    * http://groups.google.com/group/django-developers

... and in the ``#django-dev`` IRC channel on ``irc.freenode.net``. If you're

interested in helping out with Django's development, feel free to join the

discussions there.

Django's online documentation also includes pointers on how to contribute to

Django:

    * :doc:`How to contribute to Django </internals/contributing>`

Contributions on any level -- developing code, writing documentation or simply

triaging tickets and helping to test proposed bugfixes -- are always welcome and

appreciated.

Several development sprints will also be taking place before the 1.3

release; these will typically be announced in advance on the

django-developers mailing list, and anyone who wants to help is

welcome to join in.
