v5.9.0

What's Changed

New components

• KMultiSelect: A searchable select component that supports single and multiple selections, flat arrays, and deeply nested hierarchical trees with cascading selection behavior. By @Prashant-thakur77 in #1272, #1273, #1274, #1289, #1293 and #1296.

KListbox

• Updates KListbox messages prop to accept both plain strings and string functions. By @Prashant-thakur77 in #1291.
• Adds support for new single-select mode for KSelect. For that, a new multiple prop is added, defaulting to true to switch between multi-select and single-select modes of the listbox component. By @Prashant-thakur77 in #1289 and #1293.

KThemePlugin

• Adds new theme CSS variables (--tokens-*, --brand-*, and --palette-*) emitted into a <style id="k-theme-css-variables"> head tag, initialized via KThemePlugin and synchronized with globalThemeState at runtime. By @LianaHarris360 in #1303.
  • Guidance: Note that version keys now map to a vN format (e.g., palette.grey.v_400 becomes --palette-grey-v400), while token names retain their original naming (e.g., --theme-primary).
