We're currently running pre 5.x versions of the elastic stack and want to upgrade to the latest pre 5.x versions and wanted to make sure I've got the right versions to upgrade to.  Here's what we're currently running and what I believe I want to upgrade to:

elasticsearch 2.4.1 -> 2.4.5
kibana 4.6.1 -> 4.6.4
logstash 2.4.0 -> 2.4.1
filebeat 1.3.1 -> no change

I'm also using nagioscheckbeat which is 5.0.0-alpha5 which is coming from the 0.6.0 release.

Yes I should upgrade to 5.5 and that's in the plan but not right now...

Thanks!
Jerry
