        - Fix: Unsubscribe didn't work with newer mosquitto.
        - Fix: The procedural interface broke in 1.23 (use strict related).
        - Change: retroactively updated changelog; the apparent bug in
          Mosquitto was actually a bug fix, triggering a bug in

          3.1.1 specifications.

          identifier of 0. (See change note in 1.24)

1.14  2014-05-27 13:09
    !!  - Bug fix: Unlike topics, message payloads are binary data, not text

          binary compatbile. This change has no impact on 7 bit ASCII data.
