Howdy,
We are running towards WordPress 6.4 Beta 1! Gutenberg 16.7 RC candidate was released this week. What are you most excited about for this major WordPress release? For me, it’s the Block Hooks that allow you to auto-insert blocks and the font library it empowers users to manage local fonts for their site that are independent of the design of the theme.
The best way to learn how all the new features with WordPress 6.4 work is to follow along with the 26th Call for Testing coming out of the FSE Outreach program: FSE Program Testing Call #26: Final touches by Anne McCarthy.
Congratulations to the team of Openverse for winning the Open Infrastructure Award! Many of our featured images originate at the directory of Creative Commons licensed assets. Did you know that you can search the directory directly from your image block? Try it out.
And as always, there are more updates in this edition. Enjoy!
Yours, 💕

Developing Gutenberg and WordPress
Next week is release week! WordPress 6.4 Beta 1 will be released on Tuesday, September 26th, and Gutenberg 16.7 on September 17th, 2023.
WordPress 6.4
Apart from the gazillion ‘quality of life’ improvements of site editor, writing flow, list view and blocks, there are four big features coming to 6.4: The Font Library and Management, Block Hooks, user added categories for Patterns and the image Lightbox feature
As mentioned above, Anne McCarthy published FSE Program Testing Call #26: Final touches. The instructions lead you through the array of new features for WordPress 6.4: You get to learn how to manage fonts, get your side organized using the Command Palette and rename Group blocks. Then you are asked to create a new Pattern and finish a Portfolio page. You also get to swap out patterns, and handle the display of a like button. It’s a fun call for testing for sure and the deadline for feedback is October 9th, 2023.
Gutenberg 16.7 RC
Gutenberg 16.7 Release candidate is now available for testing. It’s the last release before WordPress 6.4 Beta 1 and all new things should be already in there, except for three features, Lightbox for image blocks, Block Hooks and Font Library. Additional refinements will be made in upcoming Gutenberg releases that will be synchronized with the WordPress 6.4 release cycle all through the Beta period.
Gutenberg 16.7 has a whooping 290 PRs merged. When you consider that there has been an additional week to merge new code, it maybe isn’t so much. But of course, the changelog is again a mile long. Sarah Norris handled the release as part of the Editor Tech lead role on the underrepresented led WordPress 6.4 release.
Tammie Lister is Norris’ co-lead and joined me again for this week’s Gutenberg Changelog recording. We discussed the most important PRs during the recording of the 90th episode of the Gutenberg Changelog podcast on Thursday. The episode will arrive at your favorite podcast app over the weekend. We also discussed the features that will make it into WordPress 6.4 and what we are excited about.

Plugins, Themes, and Tools for #nocode site builders and owners
Nick Diego announced Block Visibility 3.1.0: Introducing WooCommerce and EDD controls, after improving the WooCommerce and EDD integrations for sites with large product/download catalogs. Diego mentioned a notable change to the product-based rules. “Previously, you had to select which product you wanted to target with the visibility conditions. While this is still possible, Block Visibility can now detect the current product.” he wrote.
With this version, the migration from Pro features to the free version is complete. Once you update to 3.1.x it’s safe to deactivate and uninstall the Pro edition. The complete changelog is available on GitHub
Sarah Gooding has a reported on the plugin update for the WPTavern, too.

Jamie Marsland interviewed Mike McAlister creator of the Ollie theme on Will WordPress Block Themes ever be as popular as Classic Themes? They discussed some reasons for a seemingly slow adoption of block themes.
Right on cue, Fränk Klein tweeted about the key benefit of Block Themes and Full site editing: Interoperability.
- Content written with blocks is stored as HTML. So you can transfer it to another CMS.
- Plugins that use blocks work with all block themes. Without needing an extra compatibility layer.
- These plugin blocks, if written the right way, inherit theme styles.
- And in the near future patterns (previously called reusable blocks) will be portable between themes.
- There is no page builder, theme framework, or metabox plugin that can do the same.
