We are just finishing packing our first release of UnBBayes version 3 where we are providing support for MEBN and PR-OWL. For more information in these formalisms please visit http://www.pr-owl.org.
Before lauching our new release, we thought it would be better if we had some tutorial material to help the users out! For that reason, you can already peek how the new version is going to look like. For that, just visit our wiki page in http://unbbayes.wiki.sourceforge.net/.
We hope to make this version available this month, February. So, keep tuned!
All the best,
