Dependency Changes

• Drop official Python 3.4 and 3.5 support
• Bump the pika requirement to 1.0.1+

API Changes

• Move all APIs to use the Twisted-managed connection. There are a few minor changes here which slightly change the APIs:
  1. Publishing now raises a PublishTimeout when the timeout is reached (30 seconds by default).
  2. Previously, the Twisted consume API did not validate arguments like the synchronous version did, so it now raises a ValueError on invalid arguments instead of crashing in some undefined way.
  3. Calling publish from the Twisted reactor thread now raises an exception instead of blocking the reactor thread.

Features

• The fedora-messaging cli now has 2 new sub-commands: publish and record. (PR#43)
• Log the failure traceback on connection ready failures.

Bug Fixes

• Fix an issue where reconnection to the server would fail. (#208)
• Don't declare exchanges when consuming. (#171)
• Fix Twisted legacy logging (it does not accept format parameters).
• Handle ConnectionLost errors in the v2 Factory.

Development Changes

• Many Twisted-related tests were added.
• Include tests for sample schema package.
• Update the dumps and loads functions for a new message format.

Documentation Improvements
