No, that was 1966. 1970 is new and an official update (i.e., it shows up if you "Check for Updates" from the Help menu.)
I beg to differ - 1970 DOES show up on the download site and is mentioned prominently: http://www.parallels.com/download/desktop/ it links to: http://download.parallels.com/GA/Parallels-Desktop-1970-Mac-en.dmg In big bold letters, it says "Build 1970" and underneath it says "November 1, 2006". Hit refresh on your browser and maybe you will see it - you may have the old cached version that linked to 1966.
My apologies. I was referring to this forum. I hadn't checked either the website's home page or download page. I should've read your message a bit more closely...
