yosky, please read all posts. If you did you would have seen psoTFX posted the quoted text below just a few messages above yours.
erm, I am running a little late with 2.0.4 (note 2.0.4
... not 2.2
) but it'll be nearer this weekend/just before Christmas ... not next year
Also, as with any major update (from looking at the change log posted here I am under the impression this is a major update). Its good to have a mirror of your live site. Update the mirror and get it working correctly before you move the update to the live site.
