I'm having the issue on 2.4.1: ``` [2016-10-07 01:05:47,278][INFO][node] [irony] version[2.4.1], pid[82019], build[c67dc32/2016-09-27T18:57:55Z] ... [2016-10-07 13:24:24,506][WARN][transport] [irony] Transport response handler not found of id [68647] ``` ---

Can somebody Confirm, this issue is resolved in 2.4.1 ? Also, is that easy to upgrade 2.4.0 to 2.4.1 ?? Is that a complex process? ---
