 -------
 
+1.2.1 (2013-05-20)
+++++++++++++++++++
+
+- Python 3.3.2 compatibility
+- Always percent-encode location headers
+- Fix connection adapter matching to be most-specific first
+- new argument to the default connection adapter for passing a block argument
+- prevent a KeyError when there's no link headers
+
+1.2.0 (2013-03-31)
+++++++++++++++++++
+
+- Fixed cookies on sessions and on requests
+- Significantly change how hooks are dispatched - hooks now receive all the
+  arguments specified by the user when making a request so hooks can make a
+  secondary request with the same parameters. This is especially necessary for
+  authentication handler authors
+- certifi support was removed
+- Fixed bug where using OAuth 1 with body ``signature_type`` sent no data
+- Major proxy work thanks to @Lukasa including parsing of proxy authentication
+  from the proxy url
+- Fix DigestAuth handling too many 401s
+- Update vendored urllib3 to include SSL bug fixes
+- Allow keyword arguments to be passed to ``json.loads()`` via the
+  ``Response.json()`` method
+- Don't send ``Content-Length`` header by default on ``GET`` or ``HEAD``
+  requests
+- Add ``elapsed`` attribute to ``Response`` objects to time how long a request
+  took.
+- Fix ``RequestsCookieJar``
+- Sessions and Adapters are now picklable, i.e., can be used with the
+  multiprocessing library
+- Update charade to version 1.0.3
+
+The change in how hooks are dispatched will likely cause a great deal of
+issues.

+Migrating to 1.x
+----------------
+
+This section details the main differences between 0.x and 1.x and is meant
+to ease the pain of upgrading.
+
+
+API Changes
+~~~~~~~~~~~
+
+* ``Response.json`` is now a callable and not a property of a response.
+
+  ::
+
+      import requests
+      r = requests.get('https://github.com/timeline.json')
+      r.json()   # This *call* raises an exception if JSON decoding fails
+
+* The ``Session`` API has changed. Sessions objects no longer take parameters.
+  ``Session`` is also now capitalized, but it can still be
+  instantiated with a lowercase ``session`` for backwards compatibility.
+
+  ::
+
+      s = requests.Session()    # formerly, session took parameters
+      s.auth = auth
+      s.headers.update(headers)
+      r = s.get('http://httpbin.org/headers')
+
+* All request hooks have been removed except 'response'.
+
+* Authentication helpers have been broken out into separate modules. See
+  requests-oauthlib_ and requests-kerberos_.
+
+.. _requests-oauthlib: https://github.com/requests/requests-oauthlib
+.. _requests-kerberos: https://github.com/requests/requests-kerberos
+
+* The parameter for streaming requests was changed from ``prefetch`` to
+  ``stream`` and the logic was inverted. In addition, ``stream`` is now
+  required for raw response reading.
+
+  ::
+
+      # in 0.x, passing prefetch=False would accomplish the same thing
+      r = requests.get('https://github.com/timeline.json', stream=True)
+      r.raw.read(10)
+
+* The ``config`` parameter to the requests method has been removed. Some of
+  these options are now configured on a ``Session`` such as keep-alive and
+  maximum number of redirects. The verbosity option should be handled by
+  configuring logging.
+
+  ::
+
+      import requests
+      import logging
+
+      # these two lines enable debugging at httplib level (requests->urllib3->httplib)
+      # you will see the REQUEST, including HEADERS and DATA, and RESPONSE with HEADERS but without DATA.
+      # the only thing missing will be the response.body which is not logged.
+      import httplib
+      httplib.HTTPConnection.debuglevel = 1
+      
+      logging.basicConfig() # you need to initialize logging, otherwise you will not see anything from requests
+      logging.getLogger().setLevel(logging.DEBUG)
+      requests_log = logging.getLogger("requests.packages.urllib3")
+      requests_log.setLevel(logging.DEBUG)
+      requests_log.propagate = True
+      
+      requests.get('http://httpbin.org/headers')
+
+
+
+Licensing
+~~~~~~~~~
+
+One key difference that has nothing to do with the API is a change in the
+license from the ISC_ license to the `Apache 2.0`_ license. The Apache 2.0
+license ensures that contributions to requests are also covered by the Apache
+2.0 license.

+Prepared Requests
+-----------------
+
+Whenever you receive a :class:`Response <requests.models.Response>` object
+from an API call or a Session call, the ``request`` attribute is actually the
+``PreparedRequest`` that was used. In some cases you may wish to do some extra
+work to the body or headers (or anything else really) before sending a
+request. The simple recipe for this is the following::
+
+    from requests import Request, Session
+
+    s = Session()
+    prepped = Request('GET',  # or any other method, 'POST', 'PUT', etc.
+                      url,
+                      data=data

+                      # ...
+                      ).prepare()
+    # do something with prepped.body
+    # do something with prepped.headers

+                  # etc.
+                  )
+    print(resp.status_code)
+
+Since you are not doing anything special with the ``Request`` object, you
+prepare it immediately and modified the ``PreparedRequest`` object. You then
+send that with the other parameters you would have sent to ``requests.*`` or
+``Sesssion.*``.

+Transport Adapters
+------------------
+
+As of v1.0.0, Requests has moved to a modular internal design. Part of the
+reason this was done was to implement Transport Adapters, originally
+`described here`_. Transport Adapters provide a mechanism to define interaction
+methods for an HTTP service. In particular, they allow you to apply per-service
+configuration.
+
+Requests ships with a single Transport Adapter, the
+:class:`HTTPAdapter <requests.adapters.HTTPAdapter>`. This adapter provides the
+default Requests interaction with HTTP and HTTPS using the powerful `urllib3`_
+library. Whenever a Requests :class:`Session <Session>` is initialized, one of
+these is attached to the :class:`Session <Session>` object for HTTP, and one
+for HTTPS.
+
+Requests enables users to create and use their own Transport Adapters that
+provide specific functionality. Once created, a Transport Adapter can be
+mounted to a Session object, along with an indication of which web services
+it should apply to.
+
+::
+
+    >>> s = requests.Session()
+    >>> s.mount('http://www.github.com', MyAdapter())
+
+The mount call registers a specific instance of a Transport Adapter to a
+prefix. Once mounted, any HTTP request made using that session whose URL starts
+with the given prefix will use the given Transport Adapter.
+
+Implementing a Transport Adapter is beyond the scope of this documentation, but
+a good start would be to subclass the ``requests.adapters.BaseAdapter`` class.

+OAuth 1 Authentication
+----------------------
+
+A common form of authentication for several web APIs is OAuth. The ``requests-oauthlib`` library allows Requests users to easily make OAuth authenticated requests::
+

+
+    >>> url = 'https://api.twitter.com/1.1/account/verify_credentials.json'
