v1.4.2
Release 1.4.2 is relatively small and is mostly focused on tidying up the way the library manages the connection status. Previously sync/ atomic was used to read/update the status but this led to a range of potential deadlocks, and workarounds to avoid these, which made the code difficult to follow. The new connectionStatus separates status handling from client and should simplify further development whilst resolving potential race conditions. It is my hope that users will not notice any change (@master was updated on 10th August and the updated code has been running in production at a few sites since then without issue).
A further change is that it is now possible to disable auto acknowledgment so that received messages can be manually acknowledged (or, more to the point, not acknowledged!).
