The Drupal release of 4.20 has all the details of what has changed. It should be much easier to do a full CSS theme, plus — friendly URLs!
Should increase the Googlejuice. I have to add some lines to the .htaccess file to get my most popular item working. Or rather, it’s old url.
I guess the other steps will include looking what sort of modules have been updated, and perhaps install some new ones — like smilies :p
