Added

• Add render features + render strategy (static and unmount={true | false}) (#106)
  • Also changes the API of Transition component.
    • We will now always render a div by default (unless you change this using the as={...} prop).
    • The render function prop doesn't expose a ref anymore.
    • Adds unmount prop to the Transition and Transition.Child components.
• Add displayName to all contexts (#175)
• Add disabled prop to Listbox itself, instead of the Listbox.Button (#229)

Upgrade Path

We changed the API of the Transition component to be more inline with the other API's of the various components. We now always render a div for the Transition and Transition.Child component. If you want to use a render function, then we still render a div. The render function also used do expose a ref prop, which is now not the case anymore. You can still use the as prop to change the underlying div to another element or component.
