The first quarter of the year is coming to an end, and with it, 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/ 10.3 comes as well! This release brings us some important changes to Global Styles, as well as several improvements to blocks such as the Navigation 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., enhancements to the inserter, an editor performance boost, and even a few new blocks! As always, many bugbug A bug is an error or unexpected result. Performance improvements, code optimization, and are considered enhancements, not defects. After feature freeze, only bugs are dealt with, with regressions (adverse changes from the previous version) being the highest priority. fixes are included, too.

Improving the Block toolbar

In order to provide a consistent UIUI User interface across blocks, blocks have seen their toolbars rearranged following a standard grouping layout. While the last release saw the Image block have its toolbar standardized, this time a whole set of blocks have been normalized as well, including blocks such as Button, Buttons, List, Heading, Paragraph, Quote, Audio, File, Media and Text, Video, Site Logo, Cover, and Post Featured ImageFeatured image A featured image is the main image used on your blog archive page and is pulled when the post or page is shared on social media. The image can be used to display in widget areas on your site or in a summary list of posts. blocks.

Introducing layout configuration in theme.jsonJSON JSON, or JavaScript Object Notation, is a minimal, readable format for structuring data. It is used primarily to transmit data between a server and web application, as an alternative to XML.

Themes have always had the responsibility of defining alignments in the frontend through CSSCSS Cascading Style Sheets. rules. They also define different widths for both the editor and frontend. The content width, whether they support wide alignments or not, and the CSS to support all these combinations can be very hard to write properly.

With Full Site Editing, the templates are written in blocks and edited in the site editor. This means that the editor has to match the front end as much as possible while allowing theme authors to tweak these alignments and widths in the editor. If this doesn’t happen, it causes confusion and frustration as seen in the feedback from the FSE Outreach Program. 

To address these requirements and to simplify the way themes define and style alignments, Gutenberg 10.3 introduces the concept of layout and layout configuration, a feature automatically enabled when you rely on a theme.json file (experimental-theme.json file at the moment).

Theme authors should be able to make use of this feature by adding a layout config to their theme.json file and indicating in their block templates which containers inherit that config. The layout config is also automatically applied to the post editor.

If you’re using the experimental theme.json file already, you should be able to follow these two pull requests that update the empty theme and the twenty twenty-one blocks theme to use this feature.

Changes in theme.json block supports and supported styles 

Block supports are no longer used to decide whether the styles in the theme.json file for a block should be used or not. However, block supports are still used to show UI controls in both the block & global styles 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., but themes can now use any theme.json style property that exists in any block:

"core/paragraph": {
  "typography": {
    "fontFamily": "var(--wp--preset--font-family--cambria-georgia)"
  }
}

Improvements to Navigation Block and Navigation Editor

Gutenberg 10.3 brings a number of improvements to the Navigation block and Navigation editor experience, including the list view in the Navigation editor, in-between inserter, and a better flow to build nested menus.

Inserter enhancements

This release also brings updates to inserting blocks, including improvements to keyboard navigation and accessibility for the Block Inserter, and a new “theme” category for template parts and their variations. Moreover, the slash inserter now allows typing multiple words when searching for blocks. Each of these enhancements help make it easier to find and use the blocks you want.

More theme blocks

With the goal of providing classic template tagtag A directory in Subversion. WordPress uses tags to store a single snapshot of a version (3.6, 3.6.1, etc.), the common convention of tags in version control systems. (Not to be confused with post tags.) features with blocks, up to three new blocks are introduced in this release. The LogIn/Out block is now available to provide login and logout links. Optionally, it can display the login form instead of a link by setting the available block attribute.

Two new blocks for archive pages are also available. The Term Description block displays the description of categories, tags, and custom taxonomies. On the other hand, the Archive Title block displays the title of the archive itself.

Cover block improvements

The Cover block now supports drag and drop for replacing the background image.

Editor performance improvements

In recent releases, the time it took for the editor to load increased slightly due to the growing number of patterns available in the Inserter. Gutenberg 10.3 fixed this so that the editor performs well regardless of the number of available patterns!

Performance Benchmark

The following benchmark compares performance for a particularly sizeable post (~36,000 words, ~1,000 blocks) over the last releases. Such a large post isn’t representative of the average editing experience but is adequate for spotting variations in performance.

Kudos to all the contributors that helped with the release! 👏

Thanks @gziolo for managing the release, and @annezazu and @melchoyce for helping on the release post.
