title: Is there a way to version nodes on Drupal 7?
body: <p>On a website with software documentation, I need to create a new version for a node always that the information changes for a new software release. </p>
  
  <p><em>Here is an example:
  For the product x version 1.0, I have a node (ID: 1000) that explains how to install the product. 
  When this product has a new release, the instructions need to change. Currently, what I do is to create a different node (ID: 1001) for product x version 2.0, also called how to install. The issue is that, since these two nodes are totally disconnected, as my database grows, managing these versions is getting too painful.</em></p>
  
  <p>Ideally, I wouldn't have totally disconnected nodes for the same kind of information, but version that node as the product version changes. Is there any module that allows me to do it? If not, any idea on how to solve the issue?</p>
  
  <p>Thank you</p>
