https://github.com/Imroy/pubsubclient/ is the fork I am using; it's actively being developed and worked immediately for me without any issues.
It supports QoS and even has an example of OTA updating via published message, something I'm using successfully now in my project.

Hi
I'm not sure if this is the right place but...
I am trying to hook into Really Small Message Broker from ESP Pubsubclient but server complains of “unsupported protocol MQTT version 4” Anyone else?
thanks
