Version 1.2.0

• Add support for passing a security token to AwsRequestSigner and AwsAuth helper for request. Thanks @ajpl.

Version 1.1.1

• Use quote instead of the default quote_plus so query arguments that contain spaces work (thanks @eraser-77).

Version 1.1.0

• Minimum supported python version is now 3.6.1.
• Assume empty content when signing a HEAD or DELETE request just as we do when signing a GET request. Thanks @alvassin!
• Fix bug where sign_with_headers did not include valueless query arguments in the signing process (f.e. ?acl).
