Osirion.Blazor v1.5: release notes

Version 1.5.0 was released on 21 April 2025. This post is kept for history; the current release is 4.0.0, described in Osirion.Blazor 4.0: security hardening and Fluent UI v5.

Added

• A fluent API for service registration through the AddOsirionBlazor method, with the IOsirionBlazorBuilder interface.
• CSS framework integration for Bootstrap, Fluent UI, MudBlazor and Radzen: the CssFramework enum, classes that map Osirion's CSS variables to each framework's variables, and a FrameworkIntegration parameter on OsirionStyles.
• OsirionStyleOptions, a class of its own for styling options.

Changed

• osirion-cms.css was renamed to osirion.css, because it styles every component, not only the CMS ones.
• Styling options moved from GitHubCmsOptions to OsirionStyleOptions.
• The service collection extensions were reorganized. The earlier methods kept working.

Upgrading to 1.5

Update the stylesheet link to osirion.css and move styling settings from GitHubCmsOptions to OsirionStyleOptions. The 1.5 section of the migration guide has the details.

These names belong to 1.5. Later versions changed the registration API (AddOsirion) and the theming options, so follow the current documentation for new projects.
