- ``SimpleAsyncHTTPClient`` now strips the ``Authorization`` and ``Cookie`` headers from the request
  when following a redirect to a different origin. This matches the default behavior of
  ``CurlAsyncHTTPClient``. Applications that need different behavior here can set
  ``follow_redirects=False`` and handle redirects manually. Thanks to [Yannick
  Wang](https://github.com/noobone123) for being first to report this issue, as well as additional
  reporters [Kai Aizen](https://github.com/SnailSploit), [HunSec](https://github.com/0xHunSec), and
  [Thai Son Dinh](https://github.com/sondt99).
- ``SimpleAsyncHTTPClient`` now enforces ``max_body_size`` on the decompressed size of the response,
  rather than the compressed size. This prevents a denial-of-service attack via a very large
  compressed response. Thanks to [Yuichiro Kedashiro](https://github.com/yuui25) for reporting this
  issue.
- Fixed a bug in the C extension that could have read up to three bytes past the end of an input
  array. Thanks to [Thai Son Dinh](https://github.com/sondt99) for reporting this issue.
- ``OpenIDMixin`` has improved parsing for the ``check_authentication`` response. Thanks to
  [Yannick Wang](https://github.com/noobone123) for reporting this issue.

Bug fixes
~~~~~~~~~

- ``CurlAsyncHTTPClient`` has been updated to use non-deprecated APIs, avoiding deprecation
  warnings with recent versions of ``pycurl``.
