Release Notes

Release Early, Release Often

— Eric S. Raymond, The Cathedral and the Bazaar.

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. 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.

Deprecation policy

REST framework releases follow a formal deprecation policy, which is in line with Django's 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

2.4.0

Date: 29th August 2014.

Django version requirements: The lowest supported version of Django is now 1.4.2.

South version requirements: This note applies to any users using the optional authtoken application, which includes an associated database migration. You must now either upgrade your south package to version 1.0, or instead use the built-in migration support available with Django 1.7.

  • Added compatibility with Django 1.7's database migration support.
  • New test runner, using py.test.
  • Deprecated .model view attribute in favor of explicit .queryset and .serializer_class attributes. The DEFAULT_MODEL_SERIALIZER_CLASS setting is also deprecated.
  • @detail_route and @list_route decorators replace @action and @link.
  • Support customizable view name and description functions, using the VIEW_NAME_FUNCTION and VIEW_DESCRIPTION_FUNCTION settings.
  • Added NUM_PROXIES setting for smarter client IP identification.
  • Added MAX_PAGINATE_BY setting and max_paginate_by generic view attribute.
  • Added Retry-After header to throttled responses, as per RFC 6585. This should now be used in preference to the custom X-Trottle-Wait-Seconds header which will be fully deprecated in 3.0.
  • Added cache attribute to throttles to allow overriding of default cache.
  • Added lookup_value_regex attribute to routers, to allow the URL argument matching to be constrainted by the user.
  • Added allow_none option to CharField.
  • Support Django's standard status_code class attribute on responses.
  • More intuitive behavior on the test client, as client.logout() now also removes any credentials that have been set.
  • Bugfix: ?page_size=0 query parameter now falls back to default page size for view, instead of always turning pagination off.
  • Bugfix: Always uppercase X-Http-Method-Override methods.
  • Bugfix: Copy filter_backends list before returning it, in order to prevent view code from mutating the class attribute itself.
  • Bugfix: Set the .action attribute on viewsets when introspected by OPTIONS for testing permissions on the view.
  • Bugfix: Ensure ValueError raised during deserialization results in a error list rather than a single error. This is now consistent with other validation errors.
  • Bugfix: Fix cache_format typo on throttle classes, was "throtte_%(scope)s_%(ident)s". Note that this will invalidate existing throttle caches.

  • Django 1.7 Support.
  • Fix default argument when used with serializer relation fields.

2.3.12

Date: 15th January 2014

  • Security fix: OrderingField now only allows ordering on readable serializer fields, or on fields explicitly specified using ordering_fields. This prevents users being able to order by fields that are not visible in the API, and exploiting the ordering of sensitive data such as password hashes.
  • Bugfix: write_only = True fields now display in the browsable API.

2.3.11

Date: 14th January 2014

  • JSON renderer now deals with objects that implement a dict-like interface.

2.3.9

  • Fix Django 1.6 exception API compatibility issue caused by ValidationError.
  • Include errors in HTML forms in browsable API.
  • Added JSON renderer support for numpy scalars.

  • 'Raw data' and 'HTML form' tab preference in browsable API now saved between page views.
  • Bugfix: required=True argument fixed for boolean serializer fields.
  • Bugfix: client.force_authenticate(None) should also clear session info if it exists.
  • Bugfix: Client sending empty string instead of file now clears FileField.
  • Bugfix: Empty values on ChoiceFields with required=False now consistently return None.
  • Bugfix: Clients setting page_size=0 now simply returns the default page size, instead of disabling pagination. [*]

[*] Note that the change in page_size=0 behaviour fixes what is considered to be a bug in how clients can effect the pagination size. However if you were relying on this behavior you will need to add the following mixin to your list views in order to preserve the existing behavior.

class DisablePaginationMixin(object):
    def get_paginate_by(self, queryset=None):
        if self.request.QUERY_PARAMS[self.paginate_by_param] == '0':
            return None
        return super(DisablePaginationMixin, self).get_paginate_by(queryset)

  • Bugfix: Ensure we always return 404 instead of 500 if a lookup field cannot be converted to the correct lookup type. (Eg non-numeric AutoInteger pk lookup)

  • 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.

  • OAuth 1.0a support.

  • Bugfix for serializer data being uncacheable with pickle protocol 0.
  • Bugfixes for model field validation edge-cases.
  • Bugfix for authtoken migration while using a custom user model and south.

2.2.1

Date: 22nd Feb 2013

  • Bugfix: request.DATA should return an empty QueryDict with no data, not None.

The security vulnerabilities only affect APIs which use the XMLParser class, by enabling it in any views, or by having it set in the DEFAULT_PARSER_CLASSES setting. Note that the XMLParser class is not enabled by default, so this change should affect a minority of users.

2.1.16

Date: 14th Jan 2013

  • Deprecate django.utils.simplejson in favor of Python 2.6's built-in json module.

Date: 3rd Jan 2013
