title: Which version of WiredTiger is being used by MongoDB?
body: <p>Is it possible to find out which version of WiredTiger I am using with MongoDB?
  I tried using:-</p>
  
  <pre><code>db.serverStatus().wiredTiger
  </code></pre>
  
  <p>but I can't find any version info in there.</p>
  
  <p>I installed MongoDB (v3.0.4) out of the box, so I'm trying to figure out what version of WiredTiger it ships with, and whether or not I can use a newer version of WiredTiger instead.</p>
