Release 7.1.0

Overview

This release introduces a new timeline view that allows users to see how data and trends vary through time. Users can now dynamically control how much data is visible from the timeline view to focus on a specific time period. Once you specify a period of time, elements within all views are filtered and updated accordingly.

This release also includes enhanced examples that improve user experience. New Crime Network, Commodity Flow, and Road Safety example applications are included, the look and feel of the tutorial applications have been modernized, and neighborhood retrieval has been improved.

Many additional performance and quality enhancements have been made in this release, including up to a 16 percent improvement in layout performance.
