[rules-users] where to find version 4.2.2GA in svn?

Hello, I purchased a copy of Paul Browne's "JBoss Drools Business Rules", and am trying to learn Guvnor via the book's examples. However, they are written for use in drools 4.2.2GA and seem to be incompatible with version 5.1. So, I am going the "download and build source" route. Browsing the SVN tree, this seems to be the closest tag to a "4.2.2GA" version I could find. http://anonsvn.jboss.org/repos/labs/labs/jbossrules/tags/DROOLS_SOA_4_2_1... Could someone be so kind as to confirm whether this is the correct tag for that release, or point me in the right direction? Regards, Alex
