Well, there is some information available if you follow the CVS checkins. Here's a quick bullet list of new features in CVS waiting for to be finished and released.
* New GUI install and configuration (No more editing lib-common.php or dozens of little config.php files)
* Webservices API
* OpenID support (Client only)
* Stories can be posted in wikitext and other restructuring of the story code
* Comments can be closed.
* Polls got a major overhaul
There's also the history file but it mixes bug fixes and feature updates in a rolling mishmash:

directly (reported by Joe Mucchiello) [Dirk]

for us to use some other method in the future [Dirk]

template library was used incorrectly.

the core code cannot [Oliver]

- Only allow autotags in normal blocks (bug #653) [Dirk]

- Allow comments to be closed, i.e. display the existing comments but don't
