Gutenberg（古腾堡）的作者是Gutenberg Team，目前有200,000+个有效安装。已经Tested with 5.4.1版本的wordpress。
“Gutenberg” is a codename for a whole new paradigm in WordPress site building and publishing, that aims to revolutionize the entire publishing experience as much as Gutenberg did the printed word. Right now, the project is in the first phase of a four-phase process that will touch every piece of WordPress — Editing, Customization, Collaboration, and Multilingual — and is focused on a new editing experience, the block editor.
The block editor introduces a modular approach to pages and posts: each piece of content in the editor, from a paragraph to an image gallery to a headline, is its own block. And just like physical blocks, WordPress blocks can added, arranged, and rearranged, allowing WordPress users to create media-rich pages in a visually intuitive way — and without work-arounds like shortcodes or custom HTML.
The block editor first became available in December 2018, and we’re still hard at work refining the experience, creating more and better blocks, and laying the groundwork for the next three phases of work. The Gutenberg plugin gives you the latest version of the block editor so you can join us in testing bleeding-edge features, start playing with blocks, and maybe get inspired to build your own.
