NodeBrain 0.7.4 (Dunce) is available for alpha testing with an updated NodeBrain Tutorial. This version breaks compatibility with earlier versions by folding the prior concepts of “brains”, “listeners”, and “experts” into a single “node” concept. Rules created under 0.6.x and earlier versions will not work under 0.7.x without modification. Updates to the manual pages, documents and the NodeBrain web site are expected within the next several weeks along with a beta 0.7.x release.
