This release generally completes our MVP feature set for the editor by adding inline images, block style variations, and a new columns approach. Switching focus to bugs, enhancements, compatibility, and API stability from now on. Worth noting that there’s people working on some more individual blocks (a few widgets and playlist) to be included when ready.

The most significant addition is block style variations. This will allow registration of alternate styles (based on class names) for any block, with automated real thumbnails and live previews built in to the block transformation tool. We have added them to the Quote, Button, and Separator blocks for illustration. The public API will be exposed in a future release.
