for the BlockBlock Block is the abstract term used to describe units of markup that,
composed together, form the content or layout of a webpage using the WordPress editor.
The idea combines concepts of what in the past may have achieved with shortcodes,
custom HTML, and embed discovery into a single consistent API and user experience.
Editor (a.k.a. GutenbergGutenberg The Gutenberg project is the new Editor Interface
for WordPress. The editor improves the process and experience of creating new content,
making writing rich content much simpler. It uses ‘blocks’ to add richness rather
than shortcodes, custom HTML etc. [https://wordpress.org/gutenberg/](https://wordpress.org/gutenberg/)).

Below is a breakdown of the most important developer-related changes included in
WordPress 6.7.
