Update notes

The robots.txt file was changed in this release to allow for uploaded files in /sites/ to be indexed by search engines. See http://drupal.org/node/494462 for more information. The release did not change the .htaccess and (default.)settings.php files however, so you can keep your existing files intact, if you have modifications in them.
