+
+2.5.3 (2019-04-28)
+------------------
+
+* Tested on Django 2.2. No changes were needed for compatibility.
+* Tested on Python 3.7. No changes were needed for compatibility.
+
+2.5.2 (2019-03-15)
+------------------
+
+* Improve inclusion of tests in ``sdist`` to ignore ``.pyc`` files.
+
+2.5.1 (2019-03-13)
+------------------
+
+* Include test infrastructure in ``sdist`` to allow consumers to use it.
+
+2.5.0 (2019-03-05)
+------------------
+
+* Drop Django 1.8, 1.9, and 1.10 support. Only Django 1.11+ is supported now.
+
+2.4.1 (2019-02-28)
+------------------
+
+* Fix ``DeprecationWarning`` from importing ``collections.abc.Sequence`` on
+  Python 3.7.
+
+2.4.0 (2018-07-18)
+------------------
+
+* Always add 'Origin' to the 'Vary' header for responses to enabled URL's,
+  to prevent caching of responses intended for one origin being served for
+  another.
+
+2.3.0 (2018-06-27)
+------------------
+
+* Match ``CORS_URLS_REGEX`` to ``request.path_info`` instead of
+  ``request.path``, so the patterns can work without knowing the site's path
+  prefix at configuration time.
+
+2.2.1 (2018-06-27)
+------------------
+
+* Add ``Content-Length`` header to CORS preflight requests. This fixes issues
+  with some HTTP proxies and servers, e.g. AWS Elastic Beanstalk.
+
+2.2.0 (2018-02-28)
+------------------
+
+* Django 2.0 compatibility. Again there were no changes to the actual library
+  code, so previous versions probably work.
+* Ensured that ``request._cors_enabled`` is always a ``bool()`` - previously it
+  could be set to a regex match object.
+
+2.1.0 (2017-05-28)
+------------------
+
+* Django 1.11 compatibility. There were no changes to the actual library code,
+  so previous versions probably work, though they weren't properly tested on
+  1.11.
+
+2.0.2 (2017-02-06)
+------------------
+
+* Fix when the check for ``CORS_MODEL`` is done to allow it to properly add
+  the headers and respond to ``OPTIONS`` requests.
+
+2.0.1 (2017-01-29)
+------------------
+
+* Add support for specifying 'null' in ``CORS_ORIGIN_WHITELIST``.
+
+2.0.0 (2017-01-07)
+------------------
+
+* Remove previously undocumented ``CorsModel`` as it was causing migration
+  issues. For backwards compatibility, any users previously using ``CorsModel``
+  should create a model in their own app that inherits from the new
+  ``AbstractCorsModel``, and to keep using the same data, set the model's
+  ``db_table`` to 'corsheaders_corsmodel'. Users not using ``CorsModel``
+  will find they have an unused table that they can drop.
+* Make sure that ``Access-Control-Allow-Credentials`` is in the response if the
+  client asks for it.
+
+1.3.1 (2016-11-09)
+------------------
+
+* Fix a bug with the single check if CORS enabled added in 1.3.0: on Django
+  < 1.10 shortcut responses could be generated by middleware above
+  ``CorsMiddleware``, before it processed the request, failing with an
+  ``AttributeError`` for ``request._cors_enabled``. Also clarified the docs
+  that ``CorsMiddleware`` should be kept as high as possible in your middleware
+  stack, above any middleware that can generate such responses.
+
+1.3.0 (2016-11-06)
+------------------
+
+* Add checks to validate the types of the settings.
+* Add the 'Do Not Track' header ``'DNT'`` to the default for
+  ``CORS_ALLOW_HEADERS``.
+* Add 'Origin' to the 'Vary' header of outgoing requests when not allowing all
+  origins, as per the CORS spec. Note this changes the way HTTP caching works
+  with your CORS-enabled responses.
+* Check whether CORS should be enabled on a request only once. This has had a
+  minor change on the conditions where any custom signals will be called -
+  signals will now always be called *before* ``HTTP_REFERER`` gets replaced,
+  whereas before they could be called before and after. Also this attaches the
+  attribute ``_cors_enabled`` to ``request`` - please take care that other
+  code you're running does not remove it.
+
+1.2.2 (2016-10-05)
+------------------
+
+* Add ``CorsModel.__str__`` for human-readable text
+* Add a signal that allows you to add code for more intricate control over when
+  CORS headers are added.
+
+1.2.1 (2016-09-30)
+------------------
+
+* Made settings dynamically respond to changes, and which allows you to import
+  the defaults for headers and methods in order to extend them.
+
+1.2.0 (2016-09-28)
+------------------
+
+* Drop Python 2.6 support.
+* Drop Django 1.3-1.7 support, as they are no longer supported.
+* Confirmed Django 1.9 support (no changes outside of tests were necessary).
+* Added Django 1.10 support.
+* Package as a universal wheel.
+
+1.1.0 (2014-12-15)
+------------------
+
+* django-cors-header now supports Django 1.8 with its new application loading
+  system! Thanks @jpadilla for making this possible and sorry for the delay in
+  making a release.
+
+1.0.0 (2014-12-13)
+------------------
+
+django-cors-headers is all grown-up :) Since it's been used in production for
+many many deployments, I think it's time we mark this as a stable release.
+
+* Switching this middleware versioning over to semantic versioning
+* #46 add user-agent and accept-encoding default headers
+* #45 pep-8 this big boy up
