What’s new in Gutenberg 13.8? (3 August)

“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 13.8 comes with Fluid Typography, 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, revamped Quote 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., and Template parts UXUX User experience enhancements. The release is also packed with 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 and code quality improvements. All these thanks to a fantastic team of contributors, including two first-timers.

It’s now available in the WordPress pluginPlugin A plugin is a piece of software containing a group of functions that can be added to a WordPress website. They can extend functionality or add new features to your WordPress websites. WordPress plugins are written in the PHP programming language and integrate seamlessly with WordPress. These can be free in the WordPress.org Plugin Directory https://wordpress.org/plugins/ or can be cost-based plugin from a third-party repository.

Table of contents

Fluid typography support

This new option allows themers to define text size that can scale and adapt to the screen’s real state available, so your content looks great on any screen.

Note: It’s a new feature, and the Gutenberg team would appreciate your feedback.

Revamped Quote block leveraging inner blocks

After the recent Gallery block improvements, it’s time to re-introduce the Quote block. Thanks to robust nested blocks 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., now you can shape the quotes to your heart’s content, which means that you can place any block inside the quotes 🎉 

Template part UX improvements

Template parts are essential for many themes; Gutenberg 13.8 introduces improvements for those who leverage variations and patterns to provide flexibility for their users.

The specific template part variations are now available in the block inserter, making it easy to add “HeaderHeader The header of your site is typically the first thing people will experience. The masthead or header art located across the top of your page is part of the look and feel of your website. It can influence a visitor’s opinion about your content and you/ your organization’s brand. It may also look different on different screen sizes.”, “Footer,” or “Newsletter Subscription” template parts to your site.

Speaking of easy, the new search component in the template parts replacement modal will help you find just the right pattern for the block.

Border controls for Image blocks

The Image block now supports the full range of border controls, including Color, Style, and Width. I’m curious to see what creative folks at the Museum of Block Art can accomplish after this enhancementenhancement Enhancements are simple improvements to WordPress, such as the addition of a hook, a new feature, or an improvement to an existing feature..

Accessibility enhancements

The Gutenberg team is always trying to make the Gutenberg plugin more accessible with each release, and 13.8 is no different. The release includes iterative accessibility enhancements, including improved and consistent labels and tooltips across the Editor(s), as well as more keyboard-friendly clickable elements in the “Add template” modal.
