Support (or document non-support) for Fragments

See original GitHub issue

https://github.com/reactjs/reactjs.org/pull/345

React is adding a top-level React.Fragment export that transpiles to JSX as:

<>
  <li>Stuff</li>
  <li>Things</li>
</>

React.createElement(React.Fragment, {}, ...)

Would Preact be able to support fragments or provide some type of fallback?

No, current preact expects a DOM node per vnode. This is not true for Fragments where the whole point of them is to not render anything into the DOM. So this is not easily doable (if at all) with the current architecture.

That said we have merged the PR for Fragments into our development repo last week. Fragments will be part of the next major release🎉

It is not available to the public yet and we don’t have a release estimate for now. It’s progressing nicely and we are currently working through an ever shrinking number of failing test cases and ensuring that all known bugs in the next version are fixed.

@georgiemathews We do have Fragments working in a private branch, but we haven’t had the time to make it work with hydration yet.
