What’s new in Gutenberg 15.7? (03 May)

“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 tag)  are posted following every Gutenberg release on a biweekly basis, showcasing new features included in each release. As a reminder, here’s an overview of different ways to keep up with Gutenberg and the Site Editor project (formerly called Full Site Editing)

Table of contents

Site Logo replacement via 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.

Site Logo update image workflow in sidebar

To continue the quest of streamlining creator workflows, the Site Logo 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. now offers a direct way to replace the logo in the sidebar for the block. It might seem like a minor feature, but managing a site’s branding identity warrants an easy and intuitive process. (49992)

Duotone filterFilter Filters are one of the two types of Hooks https://codex.wordpress.org/Plugin_API/Hooks. They provide a way for functions to modify data of other functions. They are the counterpart to Actions. Unlike Actions, filters are meant to work in an isolated manner, and should never have side effects such as affecting global variables and output. controls in block sidebar

Duotone / filter in the sidebar

Speaking of streamlining workflows:  Duotone is a fascinating feature for the block editor. The controls for using the preset filters or creating custom filters were hidden via the Block Toolbar. Now all controls are available with the style settings in the sidebar and allow designers and content creators easier access. (49838)

Fluid Typography scales giant fonts to small screens

Fluid typography scaled

While fluid typography arrived with WordPress 6.0, users and designers had problems with large custom fonts. The previous fluid calculation didn’t scale down enough for smaller screens. In this Gutenberg plugin release, a more refined handling of fluid typography arrived using the logarithmic scale factor to calculate a minimum font size for smaller screens. With reliable scaling calculations, designers have more typographical freedom and can better rely on the built-in responsiveness of their designs. (49707)

Other Notable Highlights

Images that have custom borders assigned show those borders also in their placeholder, for instance, in archive post templates. That way, a site owner has an indicator of what colors are involved, and it makes it less haphazard when selecting featured images for their posts. (49569

Also, the Top toolbar behavior received some refinements that received mixed comments from contributors. It’ll be interesting to learn how site owners and content creators feel about these changes. (49634). 

Patterns show up in a masonry layout in a new full-screen modal that also received some refinement. (49958, 49894). The List View experienced some important refactoring to improve 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).
