 Release History
 ---------------
 
+2.6.2 (2015-04-23)
+++++++++++++++++++
+
+**Bugfixes**
+
+- Fix regression where compressed data that was sent as chunked data was not
+  properly decompressed. (#2561)
+
+2.6.1 (2015-04-22)
+++++++++++++++++++
+
+**Bugfixes**
+
+- Remove VendorAlias import machinery introduced in v2.5.2.
+
+- Simplify the PreparedRequest.prepare API: We no longer require the user to
+  pass an empty list to the hooks keyword argument. (c.f. #2552)
+
+- Resolve redirects now receives and forwards all of the original arguments to
+  the adapter. (#2503)
+
+- Handle UnicodeDecodeErrors when trying to deal with a unicode URL that
+  cannot be encoded in ASCII. (#2540)
+
+- Populate the parsed path of the URI field when performing Digest
+  Authentication. (#2426)
+
+- Copy a PreparedRequest's CookieJar more reliably when it is not an instance
+  of RequestsCookieJar. (#2527)
+
+2.6.0 (2015-03-14)
+++++++++++++++++++
+
+**Bugfixes**
+
+- CVE-2015-2296: Fix handling of cookies on redirect. Previously a cookie
+  without a host value set would use the hostname for the redirected URL
+  exposing requests users to session fixation attacks and potentially cookie
+  stealing. This was disclosed privately by Matthew Daley of
+  `BugFuzz <https://bugfuzz.com>`_. This affects all versions of requests from
+  v2.1.0 to v2.5.3 (inclusive on both ends).
+
+- Fix error when requests is an ``install_requires`` dependency and ``python
+  setup.py test`` is run. (#2462)
+
+- Fix error when urllib3 is unbundled and requests continues to use the
+  vendored import location.
+
+- Include fixes to ``urllib3``'s header handling.
+
+- Requests' handling of unvendored dependencies is now more restrictive.
+
+**Features and Improvements**
+
+- Support bytearrays when passed as parameters in the ``files`` argument.
+  (#2468)
+
+- Avoid data duplication when creating a request with ``str``, ``bytes``, or
+  ``bytearray`` input to the ``files`` argument.
+
+2.5.3 (2015-02-24)
+++++++++++++++++++
+
+**Bugfixes**
+
+- Revert changes to our vendored certificate bundle. For more context see
+  (#2455, #2456, and http://bugs.python.org/issue23476)

+Recommended Packages and Extensions
+===================================
+
+Requests has a great variety of powerful and useful third-party extensions.
+This page provides an overview of some of the best of them.
+
+Certifi CA Bundle
+-----------------
+
+`Certifi`_ is a carefully curated collection of Root Certificates for
+validating the trustworthiness of SSL certificates while verifying the
+identity of TLS hosts. It has been extracted from the Requests project.
+
+.. _Certifi: http://certifi.io/en/latest/
+
+CacheControl
+------------
+
+`CacheControl`_ is an extension that adds a full HTTP cache to Requests. This
+makes your web requests substantially more efficient, and should be used
+whenever you're making a lot of web requests.
+
+.. _CacheControl: https://cachecontrol.readthedocs.org/en/latest/
+
+Requests-Toolbelt
+-----------------
+
+`Requests-Toolbelt`_ is a collection of utilities that some users of Requests may desire,
+but do not belong in Requests proper. This library is actively maintained
+by members of the Requests core team, and reflects the functionality most
+requested by users within the community.
+
+.. _Requests-Toolbelt: http://toolbelt.readthedocs.org/en/latest/index.html
+
+Requests-OAuthlib
+-----------------
+
+`requests-oauthlib`_ makes it possible to do the OAuth dance from Requests
+automatically. This is useful for the large number of websites that use OAuth
+to provide authentication. It also provides a lot of tweaks that handle ways
+that specific OAuth providers differ from the standard specifications.
+
+.. _requests-oauthlib: https://requests-oauthlib.readthedocs.org/en/latest/
+
+
+Betamax
+-------
+
+`Betamax`_ records your HTTP interactions so the NSA does not have to.
+A VCR imitation designed only for Python-Requests.

+If you think you have found a potential security vulnerability in requests,

+
+If English is not your first language, please try to describe the problem and
+its impact to the best of your ability. For greater detail, please use your
+native language and we will try our best to translate it using online services.
+
+Please also include the code you used to find the problem and the shortest
+amount of code necessary to reproduce it.
+
+Please do not disclose this to anyone else. We will retrieve a CVE identifier
+if necessary and give you full credit under whatever name or alias you provide.
+We will only request an identifier when we have a fix and can publish it in a
+release.
+
+We will respect your privacy and will only publicize your involvement if you
+grant us permission.
+
+Process
+-------
+
+This following information discusses the process the requests project follows
+in response to vulnerability disclosures. If you are disclosing a
+vulnerability, this section of the documentation lets you know how we will
+respond to your disclosure.
+
+Timeline
+~~~~~~~~
+
+When you report an issue, one of the project members will respond to you within
+two days *at the outside*. In most cases responses will be faster, usually
+within 12 hours. This initial response will at the very least confirm receipt
+of the report.
+
+If we were able to rapidly reproduce the issue, the initial response will also
+contain confirmation of the issue. If we are not, we will often ask for more
+information about the reproduction scenario.
+
+Our goal is to have a fix for any vulnerability released within two weeks of
+the initial disclosure. This may potentially involve shipping an interim
+release that simply disables function while a more mature fix can be prepared,
+but will in the vast majority of cases mean shipping a complete release as soon
+as possible.
+
+Throughout the fix process we will keep you up to speed with how the fix is
+progressing. Once the fix is prepared, we will notify you that we believe we
+have a fix. Often we will ask you to confirm the fix resolves the problem in
+your environment, especially if we are not confident of our reproduction
+scenario.
+
+At this point, we will prepare for the release. We will obtain a CVE number
+if one is required, providing you with full credit for the discovery. We will
+also decide on a planned release date, and let you know when it is. This
+release date will *always* be on a weekday.
+
+At this point we will reach out to our major downstream packagers to notify
+them of an impending security-related patch so they can make arrangements. In
+addition, these packagers will be provided with the intended patch ahead of
+time, to ensure that they are able to promptly release their downstream
+packages. Currently the list of people we actively contact *ahead of a public
+release* is:
+
+- Ralph Bean, Red Hat (@ralphbean)
+- Daniele Tricoli, Debian (@eriol)
+
+We will notify these individuals at least a week ahead of our planned release
+date to ensure that they have sufficient time to prepare. If you believe you
+should be on this list, please let one of the maintainers know at one of the
+email addresses at the top of this article.
+
+On release day, we will push the patch to our public repository, along with an
+updated changelog that describes the issue and credits you. We will then issue
+a PyPI release containing the patch.
+
+At this point, we will publicise the release. This will involve mails to
+mailing lists, Tweets, and all other communication mechanisms available to the
+core team.
+
+We will also explicitly mention which commits contain the fix to make it easier
+for other distributors and users to easily patch their own versions of requests
+if upgrading is not an option.

+* Authorization headers will be removed if you get redirected off-host.
+* Proxy-Authorization headers will be overridden by proxy credentials provided in the URL.
+* Content-Length headers will be overridden when we can determine the length of the content.
+
+Furthermore, Requests does not change its behavior at all based on which custom headers are specified. The headers are simply passed on into the final request.
