updateScreen messge - gestation period

[Kay C Lan]

I've just received my LC Academy Super Bundle DVD and popped it in and
viewed a few episodes. Brilliant.

I'm just wondering about the 'updateScreen' message which is mentioned in
Lesson 1 of the Game Academy; this was recorded before Christmas 2011 and
it's stated that it will be incorporated into the Engine in  'a couple of
weeks'. A similar response is in the Q&A sheet that's also included.

The 5.5.1 update came out only last month but when I checked my 5.5.1
Dictionary there is  no entry. I checked the release notes, no mention.

Is it hiding in there or was the due date miscalculated?
