The result links on the search webpage for your website are more specific. Previously they returned links that pointed to the discussion messages for the content. The result links now point to the weblog archive, relative url, or discussion message; depending on message settings.
Your websites now have a sub-title for the title of your weblog. The sub-title is the topic of your latest weblog entry.
Your websites now have a simple interface to discussion conferences. Conferences allow you to group related topics together. By default your website has four conferences: Files, General, Images, and Webpages. When you add a message that has an image or file attached, the message is automatically routed to the Images or Files conference. There is no requirement to use conferences. You can continue to use your website the way you have been if you don't need conferences.
Users of your website can now receive replies to discussion messages via email.
Superusers of your website can now set a permission for users to be emailed added/changed discussion messages. Check out the how tos < How To Email Added Messages > and < How To Email Changed Messages.
