DivineDivinity.com is a site by the publisher, CDV. I believe they know there is a later patch, they just do not care. The fact they have a link to the 1.33 patch may mean that they finally actually did some testing of it. <img src="/ubbthreads/images/graemlins/eek.gif" alt="" /> In any case, I don't think they intend to officially acknowledge / endorse the 1.34 patch.
The only difference between 1.33 and 1.34 was a fix for a potential problem in 1.33 which could reset the maps in games started under a previous version.
