Tom Sawyer Perspectives, Java Edition

Releases

Release 12.0.0

DateOctober 25, 2023
StatusGeneral

Overview

This release includes further usability improvements to create and use Perspectives applications. The new Load Neighbors feature allows Perspectives users to incrementally load data for all views, without custom code, and without needing to know the Gremlin or Cypher query languages. The ability to commit changes made in the model back to the database is now available with projects that use Query Builder. Schema Editor now includes functionality to add comments and flags to schema element types and attributes. The drawing view now supports the ability to create and configure labels for meta-edges based on the data of model elements represented by the meta-edge.

Analysis improvements include the addition of the new PageRank Centrality analysis algorithm as well as the ability to add Cycle Breaking Edge Detection and Minimum Spanning Tree algorithms directly in the Designer. The Generate Web Application Code feature now supports projects that contain custom Java code.

This version of Perspectives also includes completely redesigned documentation. The updated documentation has a new look and feel, is more responsive, is easier to search and navigate, includes embedded videos, and lets you copy and send URL links to specific topics.

Many third-party libraries have been updated to eliminate potential vulnerabilities.
