+2.5.3 (2015-02-24)
+++++++++++++++++++

+**Bugfixes**
+
+- Revert changes to our vendored certificate bundle. For more context see

+
+2.5.2 (2015-02-23)
+++++++++++++++++++
+
+**Features and Improvements**
+
+- Add sha256 fingerprint support. (`shazow/urllib3#540`_)
+
+- Improve the performance of headers. (`shazow/urllib3#544`_)
+
+**Bugfixes**
+
+- Copy pip's import machinery. When downstream redistributors remove
+  requests.packages.urllib3 the import machinery will continue to let those
+  same symbols work. Example usage in requests' documentation and 3rd-party
+  libraries relying on the vendored copies of urllib3 will work without having
+  to fallback to the system urllib3.
+
+- Attempt to quote parts of the URL on redirect if unquoting and then quoting
+  fails. (#2356)
+
+- Fix filename type check for multipart form-data uploads. (#2411)
+
+- Properly handle the case where a server issuing digest authentication
+  challenges provides both auth and auth-int qop-values. (#2408)
+
+- Fix a socket leak. (`shazow/urllib3#549`_)
+
+- Fix multiple ``Set-Cookie`` headers properly. (`shazow/urllib3#534`_)
+
+- Disable the built-in hostname verification. (`shazow/urllib3#526`_)
+
+- Fix the behaviour of decoding an exhausted stream. (`shazow/urllib3#535`_)
+
+**Security**
+
+- Pulled in an updated ``cacert.pem``.
+
+- Drop RC4 from the default cipher list. (`shazow/urllib3#551`_)
