Atualizações na 2026 Q1 (12.0.26.402)

Recursos

  • Explicit control over Table of Contents levels for report items
    • Report authors can now explicitly specify the level at which sections, groups, and items appear in the Table of Contents, instead of relying solely on the report hierarchy. This provides greater control over TOC structure and enables consistent, meaningful outlines across reports and report books.
  • Secure connectivity between Standalone Report Designer for .NET and Report Server for .NET
    • The Standalone Report Designer for .NET can now securely connect to Report Server for .NET using token‑based authentication. This enables report authors to open, edit, and publish reports directly to the server.
  • User permissions now allow more granular control over report access
    • Enhanced the report access security by introducing a permission rule, “Allow Reading Nested Reports,” which controls whether users can read reports embedded as sub-reports or included in a Report Book.
  • What's Improved
    • ObjectDataSource now supports async methods returning Task and ValueTask.
    • The ReportProcessor class now exposes a method to list available rendering extensions.
  • What's Changed
    • The permissions for reading reports are now applied to reports, embedded as sub-reports or included in a Report Book.
