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