What’s new in Gutenberg 13.4? (8 June)

“What’s new in 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/…” posts (labeled with the #gutenberg-new 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.)) are posted following every Gutenberg release on a biweekly basis, discovering new features included in each release. As a reminder, here’s an overview of different ways to keep up with Gutenberg and the Full Site Editing project.

It’s been a busy time in WordPress. The first WCEU since 2019 was held just a few days after the WordPress 6.0 “Arturo” release. Similarly, Gutenberg doesn’t rest and keeps bringing us goodies every other week! The 13.4 release comes with 25 enhancements and nearly 30 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.

Table of Contents

Support for button elements 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.

Gutenberg 13.4 adds support for button elements in theme.json, so themes can now add styles to their buttons using theme.json like this:

	"styles": {
		"elements": {
			"button": {
				"color": {
					"background": "black"

To make the most of this change, blocks like the Buttons, Search, Post Comments, and File blocks now make use of the new CSSCSS Cascading Style Sheets. class wp-element-button to support button elements in theme.json.

Block spacing is a very useful design tool for the Gallery block, but what if you wanted to set different horizontal and vertical gaps? Well, you can now do that by opting in to the new axial spacing available in the Gallery block’s dimension panel.

As part of the iterative improvements to the components and post sidebar, Gutenberg 13.4 brings a new look and feel to the Publish popover.

The Color UIUI User interface gets its share of improvements, too. The color-picking interface has been unified and now uses the ToolsPanel introduced in Gutenberg 12.6. This change comes with a few quality of life improvements, too, such as when pasting a hexadecimal color, the # gets automatically stripped for a smoother workflow.

Search Block variations now support query vars

Starting with Gutenberg 13.4, Search block variations can limit their search results based on the query variables provided. For example, you can create a custom Search block variation limited to search when post_type=product with the following registration:

registerBlockVariation( 'core/search', {
   name: 'test/product-search',
   title: 'Product Search Block',
   category: 'test',
   attributes: {
      query: {
         post_type: 'product'
} );

Performance Improvements

Performance is top of mind for WordPress, and Gutenberg 13.4 comes again with a few performance improvements.

On the frontend, Global Styles CSS is enqueued conditionally only for the blocks currently in the page being loaded, resulting in serving smaller pages to the client.

As far as the Editor is concerned, the autocomplete performance has been improved. Last, but not least, the ReactReact React is a JavaScript library that makes it easy to reason about, construct, and maintain stateless and stateful user interfaces. https://reactjs.org/. Spring dependency has been upgraded, resulting in more efficient resource usage when the Block Editor is idle.
