A new beta version (2.2.0) of the Path Landscape Model Framework is available for download at www.apexrms.com/path
This latest version includes a new significant new feature: a "box-and-arrow" editor for transitions, allowing users to visually create and edit their state-and-transition models directly within Path. This new editor means that users no longer need to use VDDT to create and edit their models prior to running them in Path.
Note that this is a beta version, and as such is still undergoing testing and revision. In addition, the documentation and training materials have not yet been updated to match the current features. A full release is anticipated in early February 2011.
