Updated the GS classes to use new-style classes as well.
Remove unnecessary '?' from req.path on POST

The if/else logic in add_auth on line 491 only handles if qs and POST.

But if you're POSTing with no query string, execution falls into the else condition on line 497 and an unnecessary '?' is added with a blank query string.

My elastictranscoder.create_job calls were failing due to the unnecessary '?' in the path. It would return:

JSONResponseError: 403 Forbidden
{u'message': u"When Content-Type:application/x-www-form-urlencoded, URL cannot include query-string parameters (after '?'): '/2012-09-25/jobs?'"}

I'm not sure why, but the bug only happens when running on Google App Engine. My local dev_appserver was able to make the create_job request just fine.

Dyanamo Table.scan() should accept 'attributes' argument
Add EC2 associate_address_object method

Fixes #1874, #1893.
Adding unit test for table scan on specific attrs
Fixed a quoting bug of special characters in S3.
Populate both next_token and nextToken. Fixes #1968.

This bug was introduced due to an issue with how boto handled the nextToken
field in responses, which meant that it was exposed with the incorrect
name. The fix caused existing code to break, so now both versions are made
available. New code should use next_token.
Added release notes for 2.22.1.
Bumped to v2.22.1!
Merge branch 'hotfix-2.22.1'
Merge branch 'hotfix-2.22.1' into develop
Make sure associate address failure returns false

Modifies EC2 connection to use common code for both associate_address and
