Tom Sawyer Perspectives, Java Edition

Release 10.2.0

Overview

This release includes new features that make it easier to design and build an application with Perspectives. The view layout editor has a drag-and-drop interface for creating a custom, dashboard-style arrangement of the views in your application. And when your Perspectives project file is complete, you can automatically generate web application code for it. The Designer generates the files needed to compile and run the application or package it for deployment to a web server.

Release 10.2.0 also includes support for OAuth 2.0 user authentication for the Designer and applications created with the Perspectives platform.

The Amazon Neptune integrator supports the openCypher query language, and graph database integrators that use automatic bindings support commit functionality. Hierarchical layout with orthogonal routing has been improved to reduce crossings. Bundle layout includes improved placement of nodes, edge routing, and placement of nodes in nested drawings. A simplified framework has been extended to map, chart, and timeline view actions and generic actions that are not view-specific. Performance has been improved for node labeling, image node UIs, and schema lookups. Many third party libraries have been updated to eliminate potential vulnerabilities.
