Release Notes

2.0.0 (May 14th, 2026)

Breaking Changes

All Platforms

• The legacy Java and WPF engine backends have been removed.
• Legacy chart types have been removed.
• The deprecated DateFilter property has been removed.
• RVDashboardThumbnailView has been deprecated in favor of the new RVThumbnail class.
• NumberOfItemsInGrid, FilterRangeText, and UpdateFilterRangeText have been renamed to FilterCount, FilterSelectionText, and UpdateFilterSelectionText.

Node

• The dateFilter property on headless export options is deprecated. Use the filters array with RVDateRule instead.

Java

• The Java SDK now requires Java 17 or higher.
• The Java SDK now uses the io.revealbi:reveal-sdk-servlet Maven artifact and a servlet-based setup with RevealEngineServlet.
• The Java SDK supports Linux, Windows, and macOS, with both x64 and arm64 architectures.
• If you use Jetty as your server, its version might conflict with the Jetty version used internally by Reveal SDK, which is currently 12.0.12.

New Features

All Platforms

• New data source: Azure CosmosDB.
• New data source: ClickHouse.
• Conditional formatting can now be applied based on field values for Grid, Pivot, Bar, Column, and Text visualizations. In addition to comparing against a fixed (static) value, conditional formatting rules support comparing a field's value against another field in the same visualization. The formatting is then evaluated independently for each row based on that row's actual data. Read more..
• New RVThumbnail class for programmatically generating thumbnails of dashboards and individual visualizations.
• The DataGrid visualization now supports cell selection, multi-cell drag selection, and copying cell values to the clipboard via Ctrl+C, along with an updated column header, alternate row, and cell border design.
• RevealView is now available as a standalone npm package.
• MaxCellsRestriction now exposes get and set accessors.
• Keyboard navigation is now enabled by default. Widget titles and interactive elements include improved ARIA attributes for screen readers.
• A draggable splitter has been added to the visualization editor between the chart and data areas.
• Integrated authentication for SQL Server connections has been improved.
• The official Microsoft SQL Server client library now replaces the previous internal implementation.
• Data agent connection recovery has been improved to handle network interruptions more reliably.

Java

• The Java SDK now has feature parity with the .NET SDK for connectors and extension points, with the exception of InMemoryDataProvider, which will be ported to Java in a future release.
• The Java SDK now supports Redis caching via RVRedisOptions.
• DefaultDashboardTheme is now supported.
• Headless export now supports CSV format.

CsvExportOptions options = new CsvExportOptions();
options.setUseFormattedValues(true);
byte[] result = dashboardExporter.exportToCsv("dashboardId", options);

• IRVDataModelProvider is now available as a beta API, enabling custom field schemas, calculated fields, and custom measures — matching the existing .NET implementation.

public class MyDataModelProvider implements IRVDataModelProvider {
    @Override
    public void editSchema(IRVUserContext userContext, RVDashboardDataSet dataSet, RVDataSchema schema) {
        // customize field schema, inject calculated fields, add custom measures
    }
}

• Cache settings previously only available in .NET — including maxDownloadSize and maxInMemoryCells — are now exposed in the Java SDK.
• RVDateRule is now available for headless export date filters. The dateFilter property is deprecated — use filters instead.

ExportOptions exportOptions = new ExportOptions();
exportOptions.setFilters(List.of(new RVDateRule(RVPeriodType.YEAR, RVPeriodRelation.TO_DATE)));

Node

• IRVDataModelProvider is now available as a beta API, enabling custom field schemas, calculated fields, and custom measures — matching the existing .NET implementation.

class MyDataModelProvider implements IRVDataModelProvider {
  async editSchema(userContext, dataSourceItem, schema) {
    // Modifies existing fields in the schema (e.g. changing defaultAggregation, label, or description). Return the modified array to apply changes, or null to keep the original.
    schema.find(f => f.name === "Discount").defaultAggregation = RVDashboardAggregationType.CountDistinct;
    schema.find(f => f.name === "UnitPrice").label = "Price per Unit";
    return schema;
  }
  async getCalculatedFields(userContext, dataSourceItem) {
    // Injects new computed fields using expressions that reference existing field names (e.g. [UnitPrice] * [Quantity]). These show up as additional fields in the visualization editor.
    return [{ name: "LineTotal", type: RVDashboardDataType.Number, expression: "[UnitPrice] * [Quantity] * (1 - [Discount])" }];
  }
  async getMeasures(userContext, dataSourceItem) {
    // Injects custom aggregate measures using expressions like sum(...), sumif(...), or PREVIOUS(...). These appear as available measures when building visualizations.
    return [{ name: "Total Revenue", expression: "sum([UnitPrice] * [Quantity])", description: "Revenue before discount" }];
  }
}

• Cache settings previously only available in .NET — including maxDownloadSize and maxInMemoryCells — are now exposed in the Node SDK.

const revealOptions: RevealOptions = {
    maxDownloadSize: 200 * 1024 * 1024,
    maxInMemoryCells: 10_000_000,
};

• RVDateRule is now available for headless export date filters. The dateFilter property is deprecated — use filters instead.

const exportOptions = new ExportOptions();
exportOptions.filters = [new RVDateRule(RVPeriodType.Year, RVPeriodRelation.ToDate)];

Bugs

All Platforms

• Not all chart series were rendered, and hovering on a combo stacked series caused a crash.
• Keyboard focus was lost when a dashboard finished loading.
• Gauge visualization did not clamp to its maximum value when the data value exceeded it.
• Concurrent calls to overrideLocale could produce incorrect behavior.
• parseISODate was not available in the TypeScript-only build.
• Thumbnail generation failed for certain chart types.
• Localization did not work correctly when using module bundlers.
• The RevealView constructor did not correctly accept a CSS selector string — only DOM elements worked.
• Date fields were assigned an incorrect column type in RVJsonSchemaConfigBuilder.
• A null reference crash occurred in the pivot field editor when Data was not set.
• Opening conditional formatting rules with null or empty color properties caused a crash.
• Mismatched filters caused headless export to fail.
• An error occurred when navigating back after following a dashboard link.
• MongoDB VerifyConnection was failing unexpectedly.
• A regression caused filterValueChangedEvent to not fire correctly.
• The "titles in first row" parameter for Excel data source items was being incorrectly set.
• Missing title in the datasource selector dialog.
