With this new version, WordPress brings you fresh colours. The editor helps you work in a few places you couldn’t before without getting into code or hiring a pro. The controls you use most are right where you need them. Layout changes that should be simple, are even simpler to make.
Now the new editor is easier to use
Font-size adjustment in more places: now, font-size controls are right where you need them in the List and Code blocks. No more trekking to another screen to make that single change!
Reusable blocks: several enhancements make reusable blocks more stable and easier to use. And now they save automatically with the post when you click the Update button.
Inserter drag-and-drop: drag blocks and block patterns from the inserter right into your post.
