Breaking changes:

Report Viewer

The transparent background color is not supported in the 1D Barcode due to text overlapping issue in BarcodeLib library 3.0.3 upgrade.

Report Server

The old viewer and designer have been deprecated. The new viewer and designer will now be enabled by default in the following areas: report viewing, report designing, exporting, and embedding.

Removed the following options from the report server listing context menu as part of application security and usability improvements:

  • Views
  • Clone
  • Make Public


The context menu option to display all views associated with the report has been removed. However, users can still access the same views from the Report Viewer.


Existing cloned reports will continue to work without any issues. However, reports will no longer be cloned in the future.

Public Reports:

  • Existing public reports will render without any issues.
  • The “Make Public” option has been removed for reports.
  • The “Make Private” option will be shown for existing public reports. We recommend making all public reports private and disabling the “Mark reports as public” option from the report settings page.
  • As an alternative to the Public Reports feature, we recommend using the following embedding features as needed,
Note: The Public Reports feature will be removed in upcoming releases.

Known Bugs / Limitations:

  • ETL Service not supported in Azure App Service.
  • ETL Service – MSSQL connector doesn’t support spatial, Point, and geometry data types.


  • Provided support for known domains to mitigate both SSRF attacks and open redirect vulnerabilities.
  • Enhanced server security by implementing Subresource Integrity (SRI) and XSS prevention measures.


The Bold Reporting Tools ASP.NET MVC and Web Forms will not be deployed in the embedded build. However, bug fixes are diligently transferred to our public repositories until Microsoft officially announces the end of support for these platforms. For new web application development or to stay up-to-date, Blazor or ASP.NET Core are recommended.
