Here are some quick screenshots taken from the BPS2.
Software interface
The new provider software now has a nicer interface and better tools.
Configuration Tool
There is a new Configuration tool available that makes configuring the software an easier task.
The configured database structure is visually shown using graphviz.
The Mapping window now displays the content schemas like a tree and provides more information.
With the Concept Retrieval Tool it is now easier to find your concepts in a conceptual schema. The documentation is shown together and it is possible to do searches on the concepts.
Query Tool
The Query Tool has been completely redisigned. Now you can create much more complicated interfaces to your database.
Personalization of the interfaces is now being done trough XSLT so any kind of interface is now possible to your content schema!
Testing Tool
New testing tools try to make it easier to debug your provider installation, now more raw protocols, now you can see debug in nice HTML!
