Release Notes
=============
development
-----------
* Saner template variable autoescaping.
* Use `staticfiles` for css files.
- Easier to override. Won't conflict with customised admin styles (eg grappelli)
* Drop implied 'pk' filter if last arg in urlconf is unnamed.
- Too magical. Explict is better than implicit.
* Bugfixes:
- Bug with PerUserThrottling when user contains unicode chars.
0.3.2
-----
* Bugfixes:
* Fix 403 for POST and PUT from the UI with UserLoggedInAuthentication (#115)
* serialize_model method in serializer.py may cause wrong value (#73)
* Fix Error when clicking OPTIONS button (#146)
* And many other fixes
* Remove short status codes
- Zen of Python: "There should be one-- and preferably only one --obvious way to do it."
* get_name, get_description become methods on the view - makes them overridable.
* Improved model mixin API - Hooks for build_query, get_instance_data, get_model, get_queryset, get_ordering
0.3.1
-----
* [not documented]
0.3.0
-----
* JSONP Support
* Bugfixes, including support for latest markdown release
0.2.4
-----
* Fix broken IsAdminUser permission.
* OPTIONS support.
@ -11,20 +45,24 @@
* Drop mentions of Blog, BitBucket.
0.2.3
-----
* Fix some throttling bugs.
* ``X-Throttle`` header on throttling.
* Support for nesting resources on related models.
0.2.2
-----
* Throttling support complete.
0.2.1
-----
* Couple of simple bugfixes over 0.2.0
0.2.0
-----
* Big refactoring changes since 0.1.0, ask on the discussion group if anything isn't clear.
The public API has been massively cleaned up. Expect it to be fairly stable from here on in.
@ -49,9 +87,11 @@
You can reuse these mixin classes individually without using the ``View`` class.
0.1.1
-----
* Final build before pulling in all the refactoring changes for 0.2, in case anyone needs to hang on to 0.1.
0.1.0
-----
* Initial release.
