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 from RevealView, RVDashboard, RVDateDashboardFilter, RevealSettings, IExportOptions, and related classes.
• RVDashboardThumbnailView has been deprecated in favor of the new RVThumbnail class.
• SQL Server-based connectors now use the official Microsoft SQL Server client library, which requires trusted TLS certificates by default. If your SQL Server, Azure SQL, or Azure Synapse connection uses an untrusted or self-signed certificate, set TrustServerCertificate during the data source setup.

Node

• The dateFilter property has been removed from the headless export options. Use the filters array with RVDateDashboardFilter and 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. It replaces the deprecated RVDashboardThumbnailView API and supports runtime theme changes.

import { RVThumbnail } from "reveal-sdk";

async function renderThumbnail() {
  await RVThumbnail.fromDashboard("#thumbnail", "Sales");
}

renderThumbnail();

• 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.
• 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);
CompletableFuture<InputStream> result = dashboardExporter.exportToCsv("dashboardId", null, 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 CompletableFuture<List<RVDataModelField>> editSchema(RVDataSourceItem dataSourceItem, List<RVDataModelField> schema, IRequestContext requestContext) {
        // customize field schema
        return CompletableFuture.completedFuture(schema);
    }

    @Override
    public CompletableFuture<List<RVDataModelCalculatedField>> getCalculatedFields(RVDataSourceItem dataSourceItem, IRequestContext requestContext) {
        // inject calculated fields
        return CompletableFuture.completedFuture(null);
    }

    @Override
    public CompletableFuture<List<RVDataModelMeasure>> getMeasures(RVDataSourceItem dataSourceItem, IRequestContext requestContext) {
        // inject custom measures
        return CompletableFuture.completedFuture(null);
    }
}

• 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.

ExportOptions exportOptions = new ExportOptions();
exportOptions.getFilters().add(new RVDateDashboardFilter(new RVDateRule(RVPeriodRelation.TO_DATE, RVPeriodType.YEAR)));

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 has been removed — use filters instead.

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

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.
