Webquest is not part of 1.2. I am not even sure that it is developed into something usable (sorry, if I am wrong -> I would then like to use it!!)
The release date for 1.3 in the future document is the 31st of March. However Prem is right not to call that a promise. If I were you, and were a bit nervous about updating, I would wait for 1.3.
