title: angular 4.1.0 compatibility
body: <p>I am currently using angular 2.0.0-rc.4. I would like to convert it to 4.1.0.
  <strong>Is 2.0.0-rc.4  compatible with 4.1.0?</strong> I read in <a href="http://angularjs.blogspot.in/2017/03/angular-400-now-available.html" rel="nofollow noreferrer">this</a> document that it is backwards compatible with 2.x.x , Is 2.0.0-rc.4 includes in 2.x.x?</p>
