Infragistics Blog - #release notes

Ignite UI CLI 15 (releases 15.0.0 through 15.5.0) turns the CLI into the setup layer of the Ignite UI AI-assisted development toolchain. Highlights: the Ignite UI CLI MCP server with documentation and API lookup for AI assistants across Angular, React, Web Components, and Blazor; the ai-config command for one-command Agent Skills and MCP configuration; Blazor project scaffolding via dotnet new igb-blazor; and modernized Angular templates on signals and Angular 22. CLI 15.0.0 removes the legacy igx-ts-legacy, ig-ts, and igr-es6 project types.

Ignite UI for Angular 22 ships derived themes for the Data Grid - set three color properties on grid-theme() and nested buttons, inputs, chips, and scrollbars realign automatically - plus a dedicated excel-filtering-theme() function and an updated Select dropdown position. Two default changes need attention on upgrade: input type is now box (ng update preserves the old line look), and Select positioning moved to AutoPositionStrategy.
