Kendo UI 2025 Q4

Rendering Changes

Map

The positional CSS classes used for Map controls (attribution, navigator, and zoom) have been updated to align with modern CSS practices:

Old Classes	New Class
k-pos-top k-pos-left	k-top-start
k-pos-top k-pos-right	k-top-end
k-pos-bottom k-pos-left	k-bottom-start
k-pos-bottom k-pos-right	k-bottom-end

These classes are applied to the control wrapper elements based on the position configuration of the Map controls (attribution, navigator, and zoom). The API values for the position property (topLeft, topRight, bottomLeft, bottomRight) remain unchanged.

Kendo UI 2025 Q3

Chat

Starting with the 2025.3.825 Kendo UI for jQuery version, the Chat component has been completely redesigned. The API is updated accordingly to support the newly introduced features.

AIPrompt

• The showOutputRating property is deprecated as there is now outputActions configuration option that is more flexible.

• The outputRatingChange event is deprecated. Use outputAction event instead.

• The outputCopy event is deprecated. Use outputAction event instead.

• The k-prompt-suggestion class on the role='listitem' element has been replaced with the k-suggestion class.

Kendo UI 2025 Q2

Pager

Starting with Q2 2025, the Pager provides an adaptive mode that enhances its responsive behavior and optimizes the user experience on different screen sizes.

The adaptive mode introduces several notable changes to the default Pager behavior:

• Input Behavior Change: When the input option is set to true, the Pager now renders a NumericTextBox in place of numerical buttons for pages, rather than displaying a textbox next to the arrow buttons.

• No Numeric Buttons: When input is true, numerical page buttons are not rendered at all.

• Page Selection Dropdown Replacement: The dropdown for selecting a page is replaced with a NumericTextBox.

• Removal of numbersSelectLabel Property: This property has been removed as the select element is no longer used.
