Separator: the new Separator web component can be used both horizontally and vertically, and also display a text label.
Enhancements
Action List and Select: the new "item limit" feature limits how many options are loaded in the list. This fixes performance issues when there are too many items. The default value is 1000, but can be overwritten with the item-limit attribute.
Card: added support for labels in hover state.
Changes
Chart: improved display for null values.
Fixes
Button: fixed alignment for back button in dialog.
Date-Time Picker: fixed issue with AM-PM selectors when changing time.
