Welcome to Django 1.0!
+We've been looking forward to this moment for over three years, and it's finally
+here. Django 1.0 represents a the largest milestone in Django's development to
+date: a web framework that a group of perfectionists can truly be proud of.
+Django 1.0 represents over three years of community development as an Open
+Source project. Django's received contributions from hundreds of developers,
+been translated into fifty languages, and today is used by developers on every
+continent and in every kind of job.
+An interesting historical note: when Django was first released in July 2005, the
+initial released version of Django came from an internal repository at revision
+number 8825. Django 1.0 represents revision 88XX of our public repository. It
+seems fitting that our 1.0 release comes at the moment where community
+contributions overtake those made privately.

-1.0 in our porting guide:
+Django 1.0 has a number of backwards-incompatible changes from Django 0.96. If you have apps written against Django 0.96 that you need to port, see our detailed porting guide:
.. toctree::
:maxdepth: 1
+A complete list of backwards-incompatible changes can be found at
+What's new in Django 1.0
+A *lot*!
+Since Django 0.96, we've made over 4,000 code commits, fixed more than 2,000 bugs, and edited, added, or removed around 350,000 lines of code. We've also added 40,000 lines of new documentation, and greatly improved what was already there.
+In fact, new documentation is one of our favorite features of Django 1.0, so we might as well start there. First, there's a new documentation site:
+The documentation has been greatly improved, cleaned up, and generally made
+awesome. There's now dedicated search, indexes, and more.
+We can't possibly document everything that's new in 1.0, but the documentation will be your definitive guide. Anywhere you see something like:
+.. versionadded:: 1.0
+ This feature is new in Django 1.0
+You'll know that you're looking at something new or changed.
+The other major highlights of Django 1.0 are:
+Re-factored admin application
+The Django administrative interface (``django.contrib.admin``) has been
+completely refactored; admin definitions are now completely decoupled from model
+definitions (no more ``class Admin`` declaration in models!), rewritten to use
+Django's new form-handling library (introduced in the 0.96 release as
+``django.newforms``, and now available as simply ``django.forms``) and
+redesigned with extensibility and customization in mind. Full documentation for
+the admin application is available online in the official Django documentation:
+See the :ref:`admin reference <ref-contrib-admin>` for details
+Improved Unicode handling
+Django's internals have been refactored to use Unicode throughout; this
+drastically simplifies the task of dealing with non-Western-European content and
+data in Django. Additionally, utility functions have been provided to ease
+interoperability with third-party libraries and systems which may or may not
+handle Unicode gracefully. Details are available in Django's Unicode-handling
+See :ref:`<ref-unicode>`.
+An improved ORM
+Django's object-relational mapper -- the component which provides the mapping
+between Django model classes and your database, and which mediates your database
+queries -- has been dramatically improved by a massive refactoring. For most
+users of Django this is backwards-compatible; the public-facing API for database
+querying underwent a few minor changes, but most of the updates took place in
+the ORM's internals. A guide to the changes, including backwards-incompatible
+modifications and mentions of new features opened up by this refactoring, is
+`available on the Django wiki`__.
+Automatic escaping of template variables
+To provide improved security against cross-site scripting (XSS) vulnerabilities,
+Django's template system now automatically escapes the output of variables. This
+behavior is configurable, and allows both variables and larger template
+constructs to be marked as safe (requiring no escaping) or unsafe (requiring
+escaping). A full guide to this feature is in the documentation for the
+:ttag:`autoescape` tag.
+``django.contrib.gis`` (GeoDjango)
+A project over a year in the making, this adds world-class GIS (`Geographic
+Information Systems`_) support to Django, in the form of a ``contrib``
+application. Its documentation is currently being maintained externally, and
+will be merged into the main Django documentation shortly. Huge thanks go to
+Justin Bronn, Jeremy Dunck, Brett Hoerner and Travis Pinney for their efforts in
+creating and completing this feature.
+See for details.
+.. _Geographic Information Systems:
+Pluggable file storage
+Django's built-in ``FileField`` and ``ImageField`` now can take advantage of
+pluggable file-storage backends, allowing extensive customization of where and
+how uploaded files get stored by Django. For details, see :ref:`the files
+documentation <topics-files>`; big thanks go to Marty Alchin for putting in the
+hard work to get this completed.
+Jython compatibility
+Thanks to a lot of work from Leo Soto during a Google Summer of Code project,
+Django's codebase has been refactored to remove incompatibilities with
+`Jython`_, an implementation of Python written in Java, which runs Python code
+on the Java Virtual Machine. Django is now compatible with the forthcoming
+Jython 2.5 release.
+See :ref:`howto-jython`.
+.. _Jython:
+Generic relations in forms and admin
+Classes are now included in ``django.contrib.contenttypes`` which can be used to
+support generic relations in both the admin interface and in end-user forms. See
+:ref:`the documentation for generic relations <generic-relations>` for details.
+``INSERT``/``UPDATE`` distinction
+Although Django's default behavior of having a model's ``save()`` method
+automatically determine whether to perform an ``INSERT`` or an ``UPDATE`` at the
+SQL level is suitable for the majority of cases, there are occasional situations
+where forcing one or the other is useful. As a result, models can now support an
+additional parameter to ``save()`` which can force a specific operation.
+See XXX for details.
+Split ``CacheMiddleware``
+Django's ``CacheMiddleware`` has been split into three classes:
+``CacheMiddleware`` itself still exists and retains all of its previous
+functionality, but it is now built from two separate middleware classes which
+handle the two parts of caching (inserting into and reading from the cache)
+separately, offering additional flexibility for situations where combining these
+functions into a single middleware posed problems.
+Full details, including updated notes on appropriate use, are in :ref:`the
+caching documentation <topics-cache>`.
+Refactored ``django.contrib.comments``
+As part of a Google Summer of Code project, Thejaswi Puthraya carried out a
+major rewrite and refactoring of Django's bundled comment system, greatly
+increasing its flexibility and customizability. :ref:`Full documentation
+<ref-contrib-comments-index>` is available, as well as :ref:`an upgrade guide
+<ref-contrib-comments-upgrade>` if you were using the previous incarnation of
+the comments application..
+Removal of deprecated features
+A number of features and methods which had previously been marked as deprecated,
+and which were scheduled for removal prior to the 1.0 release, are no longer
+present in Django. These include imports of the form library from
+``django.newforms`` (now located simply at ``django.forms``), the
+``form_for_model`` and ``form_for_instance`` helper functions (which have been
+replaced by ``ModelForm``) and a number of deprecated features which were
+replaced by the dispatcher, file-uploading and file-storage refactorings
+introduced in the Django 1.0 alpha releases.
+XXX more features?
+So many people. Really.
