title: How do you know the latest chromecast device build?
body: <p>A user of mine is reporting that there is a new chromecast version and my app broke. I have 4 different devices and they all have build 16041, but I have no idea where to check if that is the latest. I've tried rebooting all 4 of them already. </p>
  
  <p>So is there a page or blog where that is listed?</p>
  
  <p>Also as a bonus question, is there a way to get updates for when the Cast Companion Library is updated? or the sdk? </p>
  
  <p>Thanks.</p>
