    * story sections make the open submission more adaptive in that you can set individual post, dump and expiration thresholds for each section according to the story type and urgency level: stories in certain sections do not "expire" and might stay interesting and active as time passes by, whereas news-related stories are only considered "hot" over a short period of time.
- 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 "search infrastructure":
    * improved search page and integrated search functionality in the administration pages.
- added translation / localization / internationalization support:

    * 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.
