Raymond, [The Cathedral and the Bazaar][cite]. -## 2.1.x series +## Versioning + +Minor version numbers (0.0.x) are used for changes that are API compatible. You should be able to upgrade between minor point releases without any other code changes. + +Medium version numbers (0.x.0) may include API changes, in line with the [deprecation policy][deprecation-policy]. You should read the release notes carefully before upgrading between medium point releases. + +Major version numbers (x.0.0) are reserved for substantial project milestones. No major point releases are currently planned. + +## Deprecation policy + +REST framework releases follow a formal deprecation policy, which is in line with [Django's deprecation policy][django-deprecation-policy]. + +The timeline for deprecation of a feature present in version 1.0 would work as follows: + +* Version 1.1 would remain **fully backwards compatible** with 1.0, but would raise `PendingDeprecationWarning` warnings if you use the feature that are due to be deprecated. These warnings are **silent by default**, but can be explicitly enabled when you're ready to start migrating any required changes. For example if you start running your tests using `python -Wd manage.py test`, you'll be warned of any API changes you need to make. + +* Version 1.2 would escalate these warnings to `DeprecationWarning`, which is loud by default. + +* Version 1.3 would remove the deprecated bits of API entirely. + +Note that in line with Django's policy, any parts of the framework not mentioned in the documentation should generally be considered private API, and may be subject to change. + +## Upgrading + +To upgrade Django REST framework to the latest version, use pip: + + pip install -U djangorestframework + +You can determine your currently installed version using `pip freeze`: + + pip freeze | grep djangorestframework + +--- + +## 2.3.x series ### Master +* Bugfix: HyperlinkedIdentityField now uses `lookup_field` kwarg. + +### 2.3.2 + +**Date**: 16th May 2013 + +* Added SearchFilter +* Added OrderingFilter +* Added GenericViewSet +* Bugfix: Multiple `@action` and `@link` methods now allowed on viewsets. +* Bugfix: Fix API Root view issue with DjangoModelPermissions + +### 2.3.2 + +**Date**: 8th May 2013 + +* Bugfix: Fix `TIME_FORMAT`, `DATETIME_FORMAT` and `DATE_FORMAT` settings. +* Bugfix: Fix `DjangoFilterBackend` issue, failing when used on view with queryset attribute. + +### 2.3.1 + +**Date**: 7th May 2013 + +* Bugfix: Fix breadcrumb rendering issue. + +### 2.3.0 + +**Date**: 7th May 2013 + +* ViewSets and Routers. +* ModelSerializers support reverse relations in 'fields' option. +* HyperLinkedModelSerializers support 'id' field in 'fields' option. +* Cleaner generic views. +* Support for multiple filter classes. +* FileUploadParser support for raw file uploads. +* DecimalField support. +* Made Login template easier to restyle. +* Bugfix: Fix issue with depth>1 on ModelSerializer. + +**Note**: See the [2.3 announcement][2.3-announcement] for full details. + +--- + +## 2.2.x series + +### 2.2.7 + +**Date**: 17th April 2013 + +* Loud failure when view does not return a `Response` or `HttpResponse`. +* Bugfix: Fix for Django 1.3 compatiblity. +* Bugfix: Allow overridden `get_object()` to work correctly. + +### 2.2.6 + +**Date**: 4th April 2013 + +* OAuth2 authentication no longer requires unneccessary URL parameters in addition to the token. +* URL hyperlinking in browsable API now handles more cases correctly. +* Long HTTP headers in browsable API are broken in multiple lines when possible. +* Bugfix: Fix regression with DjangoFilterBackend not worthing correctly with single object views. +* Bugfix: OAuth should fail hard when invalid token used. +* Bugfix: Fix serializer potentially returning `None` object for models that define `__bool__` or `__len__`. + +### 2.2.5 + +**Date**: 26th March 2013 + +* Serializer support for bulk create and bulk update operations. +* Regression fix: Date and time fields return date/time objects by default.

See [#743][743] for more details. +* Bugfix: Fix 500 error is OAuth not attempted with OAuthAuthentication class installed. +* `Serializer.save()` now supports arbitrary keyword args which are passed through to the object `.save()` method. Mixins use `force_insert` and `force_update` where appropriate, resulting in one less database query. + +### 2.2.4 + +**Date**: 13th March 2013 + +* OAuth 2 support. +* OAuth 1.0a support. +* Support X-HTTP-Method-Override header. +* Filtering backends are now applied to the querysets for object lookups as well as lists.
