This releaseRelease A release is the distribution of the final version of an application. A software release may be either public or private and generally constitutes the initial or new generation of a new or upgraded application. A release is preceded by the distribution of alpha and then beta versions of the software. includes significant progress in consolidating the codebase and refining aspects of the experience. Notably, it introduces APIs for extending 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/ beyond blocks, allowing plugins to register a full sidebarSidebar A sidebar in WordPress is referred to a widget-ready area used by WordPress themes to display information that is not a part of the main content. It is not always a vertical column on the side. It can be a horizontal rectangle below or above the content area, footer, header, or any where in the theme. for their functionality. There are also expansions to the template support (now allows to declare nested structures), ability to duplicate blocks, various design adjustments, etc. Overall the tone has been fine tuning existing elements and simplifying implementations.
