I mentioned that in a few e-mails already, but since some people missed, I decided to send an specific e-mail for that. We made a focused effort in the last few weeks to add test cases and fix a few bugs related to dynamic rules (adding/removing rules at runtime) and also related to serialization. This is a work in progress, but we already fixed a few important scenarios in 4.0.x branch. So, if you make use of these features, we strongly advise you to build the 4.0.x branch yourself and use that instead of 4.0.4 until we release 4.0.5. Please, do not report bugs related to dynamic rules and serialization in 4.0.4 without first trying the 4.0.x branch. This will allow us to save time and focus on any eventual scenario that is still not covered. If you are a Red Hat subscription customer, you can obviously use the customer portal to request help with your use case and/or ask for an official binary build until the next version is released. For those that don't know, instructions on where to get the sources from and how to build is in the drools manual. The 4.0.x branch source is available here: http://anonsvn.labs.jboss.com/labs/jbossrules/branches/4.0.x/ Thanks, Edson -- Edson Tirelli JBoss Drools Core Development Office: +55 11 3529-6000 Mobile: +55 11 9287-5646 JBoss, a division of Red Hat @ www.jboss.com
