Updated on Aug 12, 2026

The Kendo UI for Angular 25.0.0 release introduces changes in the rendering of several components.

• Removed the k-button-primary class from the TimeSelector Now button.
• Wrapped the Now, Accept, and Cancel button text in span.k-button-text elements instead of rendering bare text nodes.

• Changed the toolbar element order to New Event button, Today button, navigation, and view selector.
• Changed the Year view popup from a Tooltip to a Popover for displaying a day's events.
