• Add NeBadgeV2 component. Compared to the V1 component:
  • Props have been refactored and streamlined
  • Uses a slot instead of a text property
  • The root element is now an inline element instead of a block one
  • kind values have been renamed for clarity
  • Minor style fixes
• Other changes:
  • NeListbox: fix width of options list
  • NeTooltip: fix slot to prevent nesting of button elements
  • NeTable: add hover color to rows
  • NeDropdownfilter: add clearSearchLabel prop
  • NeSideDrawer: add show event (useful for avoiding watch boilerplate on parent component)
  • NeButton: add story for icon-only button
