title: Do Unity functions that are obsolete still work.
body: <p>So I am converting a project from Unity 4.x to 5.x and there are a number of functions that the Unity compiler is warning me that are no longer supported or are obsolete.</p>
  
  <p>My question is do these functions still work?  (even though they are marked as obsolete)</p>
  
  <p>I know at some point they need to be updated to the newer API but for the moment I just need to fix the bugs so that the game works.  Are these functions still usable? or are they potentially the source of runtime bugs?</p>
  
  <p>Thanks</p>
