Gutenberg 2.0 is available for testing and includes a changelog that's a mile long. Accessibility, keyboard navigation, and the ability to drag-and-drop multiple images to the Gallery block are among the improvements listed.
Clicking the Publish button displays options in the sidebar rather than a drop-down menu to add polish to the publishing flow.
The Table of Contents has been redesigned to increase readability and copying and pasting has also significantly improved.
Gutenberg 2.0 covers a lot of ground and the changes are too numerous to list here. However, Matias Ventura does a great job listing the changes with links to Pull Requests on GitHub where people can see how they were made.
If you haven't tried or tested Gutenberg, now is a great time to check it out.
