2. Move any chart implementation to BlazorExpress.ChartJS.
3. Build and test your application.

Apart from the target-framework and charting changes above, existing Blazor Bootstrap component APIs remain compatible with v3.x.

✨ New Features & Enhancements

• PdfViewer: Added support for password‑protected PDFs (Issue #1184, PR #1185). When a PDF requires a password, the viewer now prompts the user instead of failing silently.

• Documentation: Added Blazor Express sections and updated chart documentation (PR #1169) to clarify usage patterns and configuration options.

🐞 Bug Fixes

• SortableList: Grabcursor not showing (PR #1152). Corrected CSS so the expected drag cursor appears, improving usability for sortable interactions.
• Buttons Docs: Corrected the name of enum ButtonSize in buttons.mdx (PR #1147) ensuring accuracy for developers referencing the docs.

⬆️ Upgrades

• Target Frameworks: Added / upgraded multi-targeting to include .NET 10.0 (PR #1201). Ensures forward compatibility and access to latest runtime features.
• Configuration: Google Map key handling updates (PR #1165) to streamline external service setup.
