Theme Twenty-Twenty- Four, WordPress 6.4, upcoming Hallway Hangouts and Developer hours—Weekend Edition 265


I had a fabulous time on our Danube River Cruise. We walked the capitals of Austria, Hungary and Slovakia, Budapest, Vienna and Bratislava, learned about the long history of the region and had excellent food and wine tastings.

In the past three weeks, a lot has happened in many corners of the Gutenberg project. It will take us more than one weekend edition to catch up.

For this edition, I kept it mostly within WordPress team posts and articles. In the next edition, I will also include content and updated from the community again.

Glad to be back. I missed you.

Yours, 💕

Developing Gutenberg and WordPress

Justin Tadlock curated What’s new for developers? (August 2023).  The seventh edition of a monthly series that cuts through all the noise, bringing you the latest features, updates, and fixes you need to know about to build on top of WordPress.

Anne McCarthy announced Introducing “To better tell the story of blocks, both within WordPress and as a broader framework for folks to consider with their next project, a new page has been created on that attempts to pull together the ease and power of blocks into a single source”.

In his Design Share: Jul 31-Aug 11, Joen Asmussen, reports on work by members of the WordPress design time. You’ll find listed various prototypes for the redesign of the Documentation and Learn WordPress site, the Showcase section of the WordPress site, and the already published design assets for the WordPress “Lionel:” 6.3 release and its new microsite and some early mock-up so of list views for the WordPress Admin section.

Saxon Fletcher, contributor on the design team, published the first design mockups for the Admin Design Kickoff. You can review videos, and screenshots with a ton of explanation of challenges and considerations. The overall look feels like an enhanced version of the Site Editor screens and concepts.

WordPress 6.3

It’s probably just me, who feels that WordPress “Lionel” 6.3 was released a long time ago, instead of just two weeks and a half. It’s been a massive release and there is still additional information published, i.e., about the considerable performance improvements and the update to the Navigation blocks and features.

Sarah Gooding reported on the created release assets: WordPress Publishes 6.3 Release Video and Landing Page Demo.

WordPress 6.4

Anne McCarthy published the Roadmap to 6.4, the next major release of WordPress, led by an all underrepresented gender release squad scheduled for November 7th, 2023. A tight release cycle with the first beta scheduled for September 26th, makes this an ambitious list of features and updates.

Part of the next WordPress release is also a new default them. Jessica Lyschik published the article Introducing Twenty Twenty-Four. “The idea behind Twenty Twenty-Four is to make a default theme that can be used on any type of site, with any topic.” she wrote.

Theme Development for Full Site Editing and Blocks

Mary Baum published The anatomy of a letterform, part 2 of the six-part series, “Make your site’s typography make a statement’ on the WordPress Developer Blog. Personally, I enjoy the primer typeface, the deep dive into the terminology and genesis of a typeface and the role it plays on the web and for readers. It’s a great preparation for the new features coming to WordPress the Font Library, a way to select, store and manage fonts on your website.

ICYMI: The 3-part series on Beyond Block Styles by Justin Tadlock is now available on the WordPress Developer Blog:

Tadlock wrote: “The goal of this series is to teach you how to work with the APIs that block developers get to play with every day. Only, you’ll use those features in a theme, instead of a block. And you’ll use code and techniques that conform to the guidelines for the WordPress theme directory.”
