The Drools team are pleased to announce the release of Drools 5.0 Final. Everyone's favourite Java Rule Engine with the delivery of version 5.0 gives genesis to the Business Logic integration Platform, which provides a unified and integrated platform for Rules, Workflow and Event Processing. It's been designed from the ground up so that each aspect is a first class citizen, with no compromises.

Drools 5.0 is now split into 4 modules, the links below provide more information and screenshots for each module:

Drools Expert

Drools Fusion

Drools Flow.

Guvnor is our web based governance system, traditionally referred to in the rules world as a BRMS. We decided to move away from the term BRMS to something based on governance, as our long term emphasis is no longer rules specific. Expert is the traditional rules engine. Fusion is the event processing side, it's a play on data/sensor fusion terminology. Finally there is Flow which is our workflow module.
