Summarizing Goodbye Guvnor. Hello Drools Workbench.
Along with the functional and feature changes we have restructured the
Guvnor github repository to better reflect our new architecture.
Guvnor has historically been the web application for Drools. It was a
composition of editors specific to Drools, a back-end repository and a
simplistic asset management system.
Things are now different.
For Drools 6.0 the web application has been extensively re-written to
use UberFire that provides a generic Workbench environment, a Metadata
Engine, Security Framework, a VFS API and clustering support.
Guvnor has become a generic asset management framework providing
common services for generic projects and their dependencies. Drools
use of both UberFire and Guvnor has born the Drools Workbench.
Drools Workbench (drools-wb)

Drools Workbench is the end product for people looking for a web application that is composed of all Drools related editors, screens and services. It is equivalent to the old Guvnor.

I hope this help.
