  <p>I just want something like <a href="http://hc.apache.org/httpcomponents-client-4.4.x/index.html" rel="nofollow noreferrer">http://hc.apache.org/httpcomponents-client-4.4.x/index.html</a>(<code>4.4.x</code>'s documentation)</p>

  <h1>My sad story</h1>
  
  <p>I'm going to use <code>HttpClient 4.1.x</code>, and can't upgrade to <code>4.3.x</code> or <code>4.4.x</code> because the parent module (which calls my module) uses <code>4.1.x</code>. This is a typical problem in large companies.</p>
  
  <p>First things first, I wanted to find the documentation for <code>HttpClient 4.1.x</code>, so I opened the home page of <code>HttppClient</code>:</p>
  
  <p><a href="http://hc.apache.org/" rel="nofollow noreferrer">http://hc.apache.org/</a></p>
  
  <p><img src="https://i.stack.imgur.com/a8hXV.png" alt="http://hc.apache.org/"></p>
  
  <p>But in the navigation I can only find documentation for <code>4.3</code> and <code>4.4</code>. I looked for something like <code>Older Versions</code> or <code>Version List</code>, but I couldn't find anything.</p>
  
  <p>Then I tried searching (Google) and found the <code>4.2.x</code> homepage. I hoped this might link to <code>4.1.x</code> documentation, but no luck.</p>
  
  <p><a href="http://hc.apache.org/httpcomponents-client-4.2.x/index.html" rel="nofollow noreferrer">http://hc.apache.org/httpcomponents-client-4.2.x/index.html</a></p>
  
  <p><img src="https://i.stack.imgur.com/OvYxY.png" alt="http://hc.apache.org/httpcomponents-client-4.2.x/index.html"></p>
  
  <p>I'm good at learning patterns, so I guess <code>4.1.x</code>'s homepage is:</p>
  
  <p><a href="http://hc.apache.org/httpcomponents-client-4.1.x/index.html" rel="nofollow noreferrer">http://hc.apache.org/httpcomponents-client-4.1.x/index.html</a></p>
  
  <p>But, again, disappointment:</p>
