No More UI Freeze When Using Large Datasets - ActiveReportsJS runs and renders reports on the client-side in the browser. There are multiple stages of report rendering - data processing, layout building and drawing. Data processing could be a heavy task if using a large data set because it involves reading, parsing and transforming operations. ActiveReportsJS now processes data in a background thread using Web Workers technology. In practice, this means that the page in the browser does not freeze when a report is bound to a large dataset. It significantly improves the user experience.
PDF/A Support - The PDF Export now allows you to generate PDF/A-compliant documents. You can set PDF/A-2b and PDF/A-3b compliance levels using the Version property of the PDF Settings in the UI, or by using API calls.
Report Layers - The brand new Layers Editor UI allows you to create and manage report layers. This feature could be useful to vary report output based on the target device - viewer, export or printed document.
Chart Overlays and Trendlines - You can now supply a chart with reference lines, reference bands and trendlines, including regressions lines and moving averages.
