Tom Sawyer Perspectives, .NET Edition, Release 8.3.2 includes many innovations that have been added into the Tom Sawyer Perspectives product line since Tom Sawyer Perspectives, .NET Edition, Release 7.6.0.
This release expands our data integration capabilities through support for Amazon Neptune, Microsoft Azure Cosmos DB, JanusGraph, and Stardog.
This release now includes schema extraction for Amazon Neptune, Neo4j, Apache TinkerPop, JanusGraph, Microsoft Azure Cosmos DB, OrientDB, SQL, RDF, and structured text files, including CSV data sources. Also, query-based commit allows for saving data back to Neo4j, Amazon Neptune, and Apache TinkerPop, JanusGraph, Microsoft Azure Cosmos DB, and OrientDB graph databases.
Tom Sawyer Perspectives has been extended with the improved node growth model to better handle inside connector labels, connector constraints to control the order and positioning of connectors, the ability to rotate connector labels, and advanced swimlane support. Connector support has been improved to include fixed-size connectors with slope-end routing, variable-sized connectors that automatically grow with the number of edges that are attached to them, and connectors nested within other connectors. These additional forms of connector support allow for more customized drawing views of complex structures. In addition, layout of connectors takes into account the labels of incident edges and connector labels and allows the connectors to grow accordingly.
The Tom Sawyer Perspectives Designer now includes support for graph analysis algorithms integration without the need for writing custom code. Designer users are able to define configuration options for the analysis algorithms and see real-time results in a drawing view.
In addition, this release brings significant performance improvement for rendering in web applications and across all of the layout styles.

Status
General
Overview
This release introduces new TinkerPop data integration to connect to data sources that support the TinkerPop graph computing framework. Through this new data integration, Tom Sawyer Perspectives now supports many graph databases such as Oracle Big Data Spatial and Graph, Neo4j, DataStax Enterprise Graph, Titan and OrientDB.
A new Systems Modeling example application illustrates how Tom Sawyer Perspectives can be used for modeling and systems engineering, using a hybrid vehicle schematic as an example.
This release adds client-side actions to support your web application to reduce interaction between the client and the server. This update reduces round trip traffic between the client and server when executing pure client-side actions.
Various improvements have been made to orthogonal layout quality and performance, as well as to the user experience, including new and more modern network UIs, updated zoom and pan controls, and improvements to the documentation.

Status
General
Overview
This release introduces play and pause media controls to the timeline view so that users can observe how data evolves over time. The user can choose to play the animation from the left side, right side, or both sides at the same time. We now also include more than a dozen chart types in the charting package.
Tom Sawyer Perspectives now offers a set of options to calculate a polished final viewport that easily animates from the initial viewport to the final viewport. We provide users with smoother transitions after global layout, incremental layout, or complexity management operations.
This release introduces a new one-line diagram layout for the Utilities market that is designed to scale to hundreds of thousands of nodes and supports geospatial hinting, nesting, constraints, and incremental layout.
The Tom Sawyer Perspectives core system has been optimized for performance. The system is up to 30% faster for multi-core and hyper-threaded server configurations. Model population, rule execution and expression evaluation, view loading, layout, and rendering are all significantly faster, particularly with large data sets. Further, this release improves product quality and features, and introduces new example applications.

Overview
This release introduces charting. It is now possible to add chart views to Tom Sawyer Perspectives web applications through Designer configuration.
A UI Editor has been integrated into the Tom Sawyer Perspectives Designer so you can create composite UIs more easily. You can now create complex UIs for drawings, nodes, edges, labels, and connectors visually with the UI Editor instead of creating UIs programmatically.
Data integration has been greatly improved by adding a new JSON data integrator, adding support for the latest Neo4j 2.2 releases, and improving XML data integration performance by as much as thirty-five percent.
This release also introduces new tools for viewing and editing. The new modeless Select and Pan tool unites the functionality of the Select tool, Pan tool, and zooming tools to eliminate the need to switch between tools. The Move tool can transfer drawing objects from one nested drawing level to another nested drawing level. Further, Tom Sawyer Perspectives adds a Reconnect Edge tool for use in web applications.
Additionally, this release adds support for visually representing edge crossings.
Finally, this release offers many new performance and quality enhancements.

Release 6.2.0
Date
July 31, 2014
Status
General
Overview
Neo4j, RDF, and REST integrators have been added. The REST integrator can connect to RESTful web services, populate a schema, and process the resulting JSON or XML streams into Tom Sawyer Perspectives models.
Additionally, HTML5 performance has been improved through reduced data traffic and updates during animation.
This release introduces desktop application tree views and inspector views. For drawing views, this release adds an option to rotate edge labels so that they run parallel to their associated edge segments. This allows for more readable drawings, especially for the straight-line layout styles with bundles of multi-edges. Lastly, a smart bend removal algorithm has been added that eliminates some unnecessary bends in an orthogonal drawing.
Several new preferences have been added to allow for a more flexible, customized experience of your applications.
