title: org.openqa.selenium.MutableCapabilities not available?
body: <p>I don't seem to have org.openqa.selenium.MutableCapabilities available in my version of Selenium. I'm using version 2.53.0.</p>
  
  <p>I'm trying to use Selenium standalone server in a Grails project and the application is crashing on this line:</p>
  
  <pre><code> ChromeOptions options = new ChromeOptions()
  </code></pre>
  
  <p>I have a feeling this may be the cause. Any help greatly appreciated.</p>
