What’s new in Gutenberg 13.6? (6 July)

“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.

The Gutenberg 13.6 release comes with four major highlighted features, many smaller enhancements, a number of accessibilityAccessibility Accessibility (commonly shortened to a11y) refers to the design of products, devices, services, or environments for people with disabilities. The concept of accessible design ensures both “direct access” (i.e. unassisted) and “indirect access” meaning compatibility with a person’s assistive technology (for example, computer screen readers). (https://en.wikipedia.org/wiki/Accessibility) improvements, and twenty-six 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. To make developing with Gutenberg easier, a number of refactors to the codebase occurred for typescript rewrites. Work around improving performance continues with many changes shipped in this release expected to lead to noticeable results when the broader efforts are completed in future releases. Finally, the Style Engine work has progressed with the option for extenders to use these features with the correct theme.jsonJSON JSON, or JavaScript Object Notation, is a minimal, readable format for structuring data.

Table of Contents

Provide patterns to select from when creating any post type

In WordPress 6.0, an APIAPI An API or Application Programming Interface is a software intermediary that allows programs to interact with each other and share data in limited, clearly defined ways. was introduced that allows patterns to appear in a modal every time a user creates a new page so that, instead of starting from scratch, a user starts with content to work from. For example, this means a user could choose between patterns for a contact page or an about page and then just fill in the details that are unique to their site.

Thanks to feedback from the community, this release expands this feature to allow the same modal to be presented to a user on other post types. For example, if a user has a book post type, they could now be presented with different ways to show the book based on patterns in a modal (book cover on the left, description on the right, book cover in the center with description below, etc).

In order to take advantage of this new API powering the current experience, you need to include core/post-content in the blockTypes for your pattern and include the postTypes where you want the modal to show in the postTypes array. If postTypes are not provided the modal just appears on the page.

Create more template types in the editor

Expanding the types of templates that can be created from within the Site Editor continues to be a high priority to open up more creative options for folks to control every aspect of their site. With Gutenberg 13.6, it’s now possible to create a template for all of the posts of a specific post type (ex: single-$postType) and, to get more granular, a template for a specific post (ex: single-$postSlug). This is all handled with a very simple UI and doesn’t require needing to know post types identifiers or post slugs, making it easy to work with.

Other Notable Highlights

Gutenberg 13.6 includes several, more general enhancements and accessibility improvements.

Clearer layout controls

For example, the “Inherit Default Layout” controls have been updated to a more understandable toggle to help users and themers alike make the design decisions they want:

More keyboard shortcuts

Two keyboard shortcuts (Strikethrough or Inline Code) have been added and a previously missing keyboard shortcut to link to a post is now properly documented in the shortcuts modal:

Simplified post scheduler

The post scheduler UI has been updated to use “Today” and “Tomorrow” when possible to make the experience more readily understandable at a glance.

New template selection UI

Previously, the template selection options took up a lot of space in the 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. to allow you to pick and choose what you wanted. With Gutenberg 13.6, this experience has switched to being a popover allowing it to take up far less space and blend in better experience-wise with other post details.

Explore the expanding theme.json engine

Gutenberg 13.6 builds on previous work to expand theme.json to allow you to create a cohesive design across blocks by allowing you to change the styles of all buttons. This relies on targeting elements which are pieces of the UI that appear in multiple blocks and whose style you should be able to change across all implementations. With this work, it means you can control a button’s style across your site in everything from the general Buttons 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. to the Search block.

For anyone building third-party blocks with buttons, this same feature can be used to interact with your block assuming the block you create provides the correct markup. Keep in mind that there’s a difference between changing the styles of an individual block on a page, which will just impact that block, and changing the style at the element level, which impacts all button blocks.

Alongside the button element, captions have also been included so you can control the style of captions across all blocks with captions, from an Image block to a Video block. That element controls the styles of captions across all the blocks. For now, captions can only be controlled using theme.json but, in the future, there will be a way to manage this in the UI.

Keep in mind that this work around targeting elements will be fairly contained as it only impacts items that can’t be codified as blocks (links, captions, buttons, etc). Because these new features are in the early stages of development, please test your themes and blocks and report any issues you might find. It all helps as development continues.

Accessibility continues to be a focus and this release has some improvements to focus management and adding in previously missing aria labels.
