Blue Book updates...

<p>Hi all,</p>

<p>Just wondering how often there a new edition of the blue book becomes available... Does any one know when the next version is coming out?</p>

<p>I would like to make sure that I'm up to date with the material is an update is coming out soon...</p>

<p>There was a new one that I think came out in February, or at least fairly recently.</p>

<p>At least early 2013, I guess.</p>
