This brings complete visibility into report scheduling and delivery, helping you quickly identify issues, reducing delays and improving operational transparency.
Smarter dynamic reporting with Cascading Parameters
We have added support for the cascading parameter API that allow reports to dynamically update dependent parameters based on user selections. Users can explore data more intuitively, enabling faster filtering, better usability, and more efficient decision-making.
Report Viewer improvements
The Report Viewer in v13.1.26 has been enhanced to deliver more accurate rendering, stronger exports, and a better localized experience.
Clearer and more organized printed reports
Printed reports are now automatically labeled with the report name as the document title, ensuring clarity and consistency. You can easily organize and identify documents, improving workflows in reporting-heavy environments.
Smarter Excel exports for faster analysis
We have added aggregation support in raw data Excel exports, you get structured and meaningful data instead of just raw entries. This allows business users to start analyzing immediately, saving time and reducing the need for manual data preparation.
Better textbox rendering with EnableFitContentMaxHeight
A new custom property, EnableFitContentMaxHeight, has been introduced in Report Viewer Preview to resolve textbox overlapping issues when rendering cell content, ensuring improved layout consistency and readability.

Better layout handling with FillEmptySpace
With the FillEmptySpace enhancement, unused areas in tables are automatically filled, resulting in a cleaner and more consistent layout. This ensures reports are presentation-ready, making them ideal for stakeholder sharing and customer-facing scenarios.

Expanded language support for global users
The Report Viewer now supports six additional languages, helping teams interact with reports in their preferred language.

This improves user comfort, adoption, and collaboration across global teams.
Report Designer enhancements
Work seamlessly with PostgreSQL UUID data
You can now use UUID data type fields in PostgreSQL dataset query filters, making it easier to work with modern database schemas. Developers can build reports more efficiently without workarounds, ensuring better compatibility and cleaner data handling.
Track report changes in real-time
Introducing the new on ReportModified event, which triggers whenever any RDL object is updated. This allows teams to track changes, trigger custom workflows, and build smarter integrations, improving development efficiency and control.
Strengthen data security during report downloads
Sensitive information is now better protected. Username and password nodes are restricted from being serialized in RDL files during on-premises downloads. This enhances data security and compliance, ensuring sensitive credentials are not exposed.
IDP enhancement
Reverse proxy support for multi-domain routing
Bold Reports now supports reverse proxy-based domain routing, allowing requests to be handled based on the request domain, without relying on a single application URL. This enables cleaner deployment architectures, simplifies embedded reporting across products, and gives teams greater control over multi-tenant and multi-domain environments.
Accelerate cloud deployment with Azure app services
Deploying Bold Reports to the cloud is now faster and more streamlined. With support for automated deployment to Azure App Services, teams can reduce manual setup and quickly launch reporting environments. This helps organizations speed up time-to-production, reduce deployment complexity, and scale effortlessly in cloud environments.
Simplify rebranding for embedded
Customizing Bold Reports to match your product experience is now easier. Enhanced automated rebranding capabilities allow teams to apply branding changes more efficiently across deployments. This is especially valuable for SaaS providers, enabling consistent white-label experiences with minimal effort.
