WordCampWordCamp WordCamps are casual, locally-organized conferences covering everything related to WordPress. They're one of the places where the WordPress community comes together to teach one another what they’ve learned throughout the year and share the joy. Learn more. US 2025 is coming up next week

From August 26–29, 2025, the WordPress community will gather in Portland, Oregon, for this year’s WordCamp US. If you haven’t already, be sure to register for the Contributor Day. CoreCore Core is the set of software required to run WordPress. The Core Development Team builds WordPress. Team members will be on site, and it would be great to see you there as well. @jorbin wrote a guide to prepare for the day.

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/ 21.4?

The latest version of Gutenberg, 21.4, was released on August 13. For a detailed overview of what has changed, check out the article What’s new in Gutenberg 21.4? – many thanks to @priethor for putting together this excellent summary.

Discussion 💬

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. Pattern Registration – Silent Failures

@tusharbharti reported an issue with the register_block_pattern() function, which currently returns true even when disallowed blocks are included. This causes the pattern to not appear in the inserter and no warning is shown. A patchpatch A special text file that describes changes to code, by identifying the files and lines which are added, removed, and altered. It may also be referred to as a diff. A patch can be applied to a codebase for testing. (PR#9345) has been submitted to address the problem, and a second opinion is requested to ensure the issue is properly resolved. See #63765

MySQLMySQL MySQL is a relational database management system. A database is a structured collection of data where content, configuration and other options are stored. https://www.mysql.com/. Rate Limiting – Redirect Issue

@anonymooo highlighted a 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. where WordPress incorrectly redirects to wp-admin/install.php when a user is rate-limited in MySQL. A patch (PR#9223) is open and requires review. Feedback on the desired behavior, such as using wp_die(), is requested to guide the next steps. See #63678

UTF-8 Handling Improvements

@dmsnell suggested updating the wp_check_invalid_utf8() function to improve UTF-8 validation, building on previous work with seems_utf8(). This update aims to strengthen UTF-8 handling in WordPress. The community is encouraged to provide feedback before the changes are finalized. See #63837

Data Passing in Scripts

@jonsurrell, in collaboration with @westonruter, proposed adapting the data passing mechanism from Script Modules for use with classic scripts. This change would offer better performance, eliminate reliance on a global namespace, and provide an alternative to wp_add_inline_script() and wp_localize_script(). Feedback on this approach is welcome. See #58873

Emoji Detection Inline Script – Render Blocking

@westonruter discussed a potential improvement for the emoji detection script. By switching from an inline script to a script module, render-blocking could be reduced, resulting in better performance, particularly on mobile devices. Early testing has shown over a 5% improvement in Largest Contentful Paint (LCP). See #63842

Props to @francina for review.
