Release Notes

Preview (weekly preview)

Changes below are available in the weekly preview builds and will ship in the next RTM release.

Bugs

All Platforms

• String values in Grid and Pivot PDF exports are no longer cut off at 200 characters. The PDF exporter previously applied its own 200-character limit on top of the engine's, so exports could show less text than the dashboard. That extra limit has been removed, and exported text now follows the engine's MaxStringCellSize setting (default 256 characters), so an export shows the same amount of text per cell as the dashboard does. To show more, raise MaxStringCellSize. Note that cells have a fixed width, so longer values wrap and increase page count.

2.2.0 (September 3rd, 2026)

Breaking Changes

• The newTooltip beta feature flag has been removed. Hover tooltips are now the default, so any call that enables the flag can be deleted.
• The new DataGrid is now the default grid visualization for the Reveal SDK. Existing Grid visualizations render with the new DataGrid without any dashboard changes. To continue using the legacy Grid, disable the newDataGrid feature flag. When conditional-formatting rules overlap on the same cell, the new DataGrid applies all matching rules in list order, with later rules taking precedence for overlapping formatting properties. This behavior differs from the legacy Grid and may affect dashboards that rely on overlapping rules after upgrading.

New Features

• Charts now support user-authored annotations, with a dedicated editor and styling options. Point, slice, and strip annotation types are available on the category chart family, and annotations are saved with the dashboard so every viewer sees the same note in the same place.
• The Grid, Pivot, Sparkline, and new DataGrid visualizations now support hyperlink columns, with URL and dashboard linking and field-token substitution. Cell and row context is passed to the dashboard-linking callback.
• The redesigned tooltip is no longer in beta and is now the default. Tooltips appear on hover for every visualization type that supports them, and tooltip actions such as drill down and filtering are available directly from the tooltip. Use RevealView.showTooltips to turn them on or off. In addition, we’ve resolved the remaining known issues with tooltip behavior, providing a more consistent experience across all visualization types.
• Visualization column hyperlinks and row-level actions now support relative URLs, which are normalized automatically when the URL field loses focus.
• The new DataGrid visualization is now the default grid for the Reveal SDK, and it also supports interactive filtering through a "Filter By" action on eligible cells.
• RVDashboard now exposes methods for loading a dashboard from JSON and serializing it back:

const dashboard = RVDashboard.loadFromJson(json);
revealView.dashboard = dashboard;

const asObject = revealView.dashboard.toJson();
const asString = revealView.dashboard.toJsonString();

• When selecting a SQL-based data source, the metadata screen now displays the data source title instead of the database name.
• The SQLite and DuckDB connectors now support parameterized custom queries.
• The PostgreSQL connector now supports stored procedures.
• Snowflake now supports applyTimeZone function.
• MongoDB connector: fields missed by schema inference can now be used explicitly.
• MongoDB query performance and join handling have been improved.
• Tables, views, and stored procedures are now sorted alphabetically for SQL data sources.
• Error messages for invalid data source URLs are now clearer.
• General Japanese resource strings have been reviewed and corrected for consistency.

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.
• The cell limit setting has moved from $.ig.RVUtility.prototype.maxCellsRestriction to RevealSdkSettings.maxCellsRestriction.
• 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))];
