Requests-oauthlib

++++++++++++++++++++

- **Removed support for Python 2.6 and Python 3.3.**
This project now supports Python 2.7, and Python 3.4 and above.
- Added several examples to the documentation.
- Added plentymarkets compliance fix.
- Added a ``token`` property to OAuth1Session, to match the corresponding
``token`` property on OAuth2Session.

+++++++++++++++++++++++++

- Added Fitbit compliance fix.
- Fixed an issue where newlines in the response body for the access token
request would cause errors when trying to extract the token.
- Fixed an issue introduced in v0.7.0 where users passing ``auth`` to several
methods would encounter conflicts with the ``client_id`` and
``client_secret``-derived auth. The user-supplied ``auth`` argument is now
used in preference to those options.

++++++++++++++++++++++++++

- Allowed ``OAuth2Session.request`` to take the ``client_id`` and
``client_secret`` parameters for the purposes of automatic token refresh,
which may need them.

+++++++++++++++++++++

- Use ``client_id`` and ``client_secret`` for the Authorization header if
provided.
- Allow explicit bypass of the Authorization header by setting ``auth=False``.
- Pass through the ``proxies`` kwarg when refreshing tokens.
- Miscellaneous cleanups.

+++++++++++++++++++++++++

- Fixed a bug when sending authorization in headers with no username and
password present.
- Make sure we clear the session token before obtaining a new one.
- Some improvements to the Slack compliance fix.
- Avoid timing problems around token refresh.
- Allow passing arbitrary arguments to requests when calling
``fetch_request_token`` and ``fetch_access_token``.

+++++++++++++++++++++++++

- Add compliance fix for Slack.
- Add compliance fix for Mailchimp.
- ``TokenRequestDenied`` exceptions now carry the entire response, not just the
status code.
- Pass through keyword arguments when refreshing tokens automatically.
- Send authorization in headers, not just body, to maximize compatibility.
- More getters/setters available for OAuth2 session client values.
- Allow sending custom headers when refreshing tokens, and set some defaults.
