TouchScreenKeyboard.active deprecated?

Something strange happened. Randomly, unity stopped caring about touchscreenkeyboard.active.

var kb : TouchScreenKeyboard;

 if(kb){
   if(kb.active)
     print("the keyboard is active");
 }

That's basically what I had, but unity suddenly doesn't care.

Now, I just have

 if(kb)
   print("keyboard is active");

and it'll determine if the keyboard is up or put away by pressing done / cancel.

Am I missing something? Has kb.active been deprecated? What are the dangers of checking if the keyboard is up or not using this method? Using unity 4.6.6 because 5 gave me some problems.
