WordPress 5.8, the new version has been released, From changelog:
After months of hard work, the power of blocks has come to both the Block Gadget Processor and the Adapter.
You can now add blocks to both gadget areas on your site and with a live preview via the Adapter. This opens up new possibilities for content creation: from codeless mini-layouts to the huge core kernel and block library. For our developers, you can find more details at Developer Notes gadget.
Overview of the Page Structure
Sometimes you need a simple landing page, but sometimes you need something a little more powerful. As blocks grow, patterns emerge, and content creation becomes easier, new solutions are needed to make it easier to navigate complex content. List View is the best way to navigate between content levels and insert blocks. Because List View provides you with an overview of all the blocks in your content, you can now quickly navigate to the exact blocks you need. Are you ready to focus fully on your content? Turn it on or off to fit your workflow.
