1.3.0

• Last planned release in the 1.x line (bug fixes will be released as 1.3.x if needed)
• Last release to support both Python 2.6+ and Python 3.2+
• Unit tests have been added to help ensure behavioral compatibility

Future releases will:

• Have major version 2.x
• Break API compatibility with 1.x
• Support only Python 3 (likely only Python 3.5+, in order to use async/await)
