- multiple vhosts + multiple directories:
    * you can setup multiple Drupal sites on top of the same physical source tree either by using vhosts or sub-directories.
- added "user ratings" similar to SlashCode's Karma or Scoop's Mojo:
    * all rating logic is packed into a module to ease experimenting with different rating heuristics/algorithms.
- added "search infrastructure":
    * improved search page and integrated search functionality in the administration pages.
- added translation / localization / internationalization support:
    * because many people would love to see their website showing a lot less of English, and far more of their own language, Drupal provides a framework to setup a multi-lingual website or to overwrite the default English text in English.
- added fine-grained user permission (or group) system:
    * users can be granted access to specific administration sections. Example: a FAQ maintainer can be given access to maintain the FAQ and translators can be given access to the translation pages.
- added FAQ module
- changed the "open submission queue" into a (optional) module.
- various updates:
    * improved account module:
        + user accounts can be deleted.
        + added fine-grained permission support.
    * improved block module
    * improved diary module:
        + diary entries can be deleted
    * improved headline module:
        + improved parser to support more "generic" RDF/RSS/XML backend.
    * improved module module
    * improved watchdog module
    * improved database abstraction layer
    * improved themes:
        + W3C validation on a best effort basis
        + added theme "example" (alias "Stone Age")
    * added new scripts to directory "scripts"
    * added directory "misc"
    * added CREDITS file
- revised documentation
