Tom Sawyer Perspectives, Java Edition

Release 7.6.0

Overview

This release introduces new Tom Sawyer Maps that combines the power of our existing rule-based drawing views and the OpenLayers map library. By combining drawings and maps, we provide an exciting new way to view your geospatial data and introduce features that are not available in either of these technologies separately.

This release also adds support for the binary Bolt protocol to our Neo4j integrator, and introduces a number of performance and memory improvements in the drawing (graph) layout system.
