• #310 017a8bb Thanks @marvinhagemeister! - Fix casing of namespaced attribute names

• #311 bccd1d6 Thanks @gpoitch! - Apply attribute name handling in pretty mode

Minor Changes

• #305 568f139 Thanks @marvinhagemeister! - Add support for error boundaries via componentDidCatch and getDerivedStateFromError

  This feature is disabled by default and can be enabled by toggling the errorBoundaries option:

  import { options } from 'preact';
  
  // Enable error boundaries
  options.errorBoundaries = true;
  

Minor Changes

• #301 659b456 Thanks @marvinhagemeister! - Add experimental ability to render HTML comments via <Fragment UNSTABLE_comment="my-comment" />. When the UNSTABLE_comment prop is present all children of that Fragment will be ignored and a HTML comment will be rendered instead. This feature is added to allow framework authors to experiment with marking DOM for hydration in the client. Note that it's marked as unstable and might change in the future.
