OK, issue#3 of the document is now available:
http://www.informit.com/promotions/promotion.aspx?promo=137519

In the light of feedback from [these people] it now has:
- an entry for file() vs. open() [Martin P. Hellwig]
- an entry for %* vs. {:{}} syntax [John Posner, Mark Dickinson, &
Carsten Haese]
- creative commons license "CC by-sa" [Antoine Pitrou]

So I hope it will prove even more useful now:-)
