I assume many of you already have an email via DriveThruRPG about this -- but we just updated the Eclipse Phase core rulebook PDF. It's mostly a cosmetic/utility update, adding a fully-hyperlinked index and touching up a few typographical and visual things. No errata-style changes!
As always, if you've already bought the PDF, the updated version should be sitting in your DriveThruRPG library. If not, you can check it out here: http://bit.ly/1MhnUBw
