TL;DR

Machine Head is a small Clojure MQTT client.

1.0.0-beta4 is a development milestone that works around a bug in Eclipse Paho Java.

Changes Between 1.0.0-beta3 and 1.0.0-beta4

Client ID Limit

MQTT spec dictates that client ID’s should be limited to 23 bytes. Eclipse Paho client generator can produce ID’s longer than that.

Machine Head now will limit ID length to the last 23 bytes.
