Drools 3.0 <http://labs.jboss.com/portal/jbossrules> the project is
about to be released and with that we will create a branch for JBoss
Rules 3.0 the product. JBoss Rules 3.0 will be a long lived stable
branch packaged with JBoss support and training goodness.
Some of the Drools project developers have got together and produced an
initial brain dump -- a "wish list" for future development - which will
form the basis of our Road Map
<http://wiki.jboss.org/wiki/Wiki.jsp?page=DroolsRoadmap>. This should
help users understand the direction we wish to take Drools. Obviously
this goes well beyond the scope of a next release and we will start to
prioritize the work soon. The assigned names are just initial first
owners, ownership will more than likely change over time. Some will ask
"what about integration with X" - several of the features in the list
are there to assist integration with projects like jBPM and Seam, e.g.
backward chaining and named facts. As always in OSS I'm sure there will
be surprised additions that surface, that are not in the list.
Feedback Welcome :)
