Select: MDC switched to using native select elements. RMWC selects should be fine with a few caveats. Props now spread to the native select by default, and a rootProps prop has been added. Also, if you were relying on MDC’s ListItem as the children, they are now standard HTML option elements. #179 (d7300093)
Slider: The Slider has been directly implemented with MDC Foundation. Please use evt.detail.value instead of evt.target.value. (1a80fa02)
IconToggle: IconToggle has been directly integrated with the MDCFoundation and the onChange callback will contain their synthetic event. See https://material.io/components/web/catalog/buttons/icon-toggle-buttons/ notifyChange (2701c34e)
ChipIcon: Added ChipIcon component which required splitting apart the Chip and ChipText component. If you were using Chips before, wrap the interior content with ChipText. (6d3eef96)
