The current version would appear to be Lasors 2008, until Lasors 2010 does finally appear.
The 2008 version is here, in case anyone is looking for it:
LASORS: LASORS 2008 | Publications | CAA
It doesn't seem to say whether or not they will publish the 2010 edition on the website for free, at least I can't find any reference to it, not that that indicates anything on their awful-to-navigate site.
