For the most trouble-free transition from an existing installation, it is recommended that you first upgrade to Drupal 4.6.3. If you are upgrading from Drupal 4.5.x or below, please consult the Drupal 4.6.0 release announcement, the Drupal 4.6.1 release announcement, the Drupal 4.6.2 release announcement, and the Drupal 4.6.3 release announcement for more information. To upgrade from Drupal 4.6.3, upload all of the files and directories in the Drupal 4.6.4 package to your webserver, replacing older copies of the files. As with any upgrade, it is a good idea to back up your site and database first.
No API or database changes have been made since Drupal 4.6.3 so all contributed themes and modules that work for 4.6.3 will work with 4.6.4.
