zk v3.4.14 issue, not compatible with curator v4x

[jeffcai]

I have zk installed with brew, which version is 3.4.14, when starting the application complains:

after upgrading the zk version to v356, the issue is gone, so it would be better to mention somewhere the zk version, same with other dependencies.
