title: Node.js 5.x v/s 0.10.x or 0.12.x
body: <p>There are two version of Node.js 5.x and 0.10.x or 0.12.x . Linked from official site <a href="https://github.com/nodesource/distributions" rel="nofollow">https://github.com/nodesource/distributions</a></p>
  
  <p>It is very confusion what is the difference. I was trying to install swagger-node on ubuntu-server, if I use 5.x it crease huge set for node-modules . However if I use 0.10.x it uses only four node-modules. So there is a difference. </p>
  
  <p>My questions are:</p>
  
  <ol>
  <li>What is a difference between 5.x v/s 0.10.x ?</li>
  <li>How to upgrade from 0.10.25 to say 0.10.40 on Ubuntu ?</li>
  </ol>
