This edition comes at you from the wonderful location of Gerolstein. A beautiful small town in the middle of the German Eifel region.

I’m here because this is the location of the very first WordCamp Germany. If you’re here as well, do come say hi!

Number 91 is a long one, hope you are ready!

🗞️ Inside WordPress News

Here’s what I saw happening this past week:

  • I talked about a demo link provided by WordPress Playground in a previous edition, and while that’s temporarily removed Marcus Burnette posted ​a very interesting trac ticket​ on how to best approach the next iteration.

Thoughtful read! And a perfect example of how this should’ve been approached from the get-go. Do read ​Rich Tabor’s thoughts on it as well​!



Speaking of the editor, there will be ​heaps of changes going into WordPress 6.4​ that you should read up on!


WordPress 6.4

​WordPress 6.4 saw it’s first Release Candidate​, and that means lots of Dev Notes have been published in the past week.

What’s not to love?! As my good friend ​Till Krüss​ said: The query splitting change is HUGE.


  • Now we’re getting somewhere 😍. WordPress 6.4 introduces ​the Block Hooks API​ which will allow a block to automatically insert itself relative to instances of other block types.

This will allow us to insert a block into any specific position hooked to any other block. Reminds me a lot of how the Genesis Framework handles things. And I love how flexible that system of hooks and filters was.



  • WordPress 6.4 allows us to ​be smarter with autoloading options​! Too many options is a common cause for slow server response time as well as bugs while using a persistent object cache. And that’s getting fixed now! 🎉

  • WordPress 6.4 will add ​image loading optimization enhancements​. There are too many wonderful changes to highlight just one, but I highly encourage you to read up on it as there are new filters introduced which you’ll want to understand.

  • ​Hard-coded style tags will be replaced​. This will replace manually created style tags printed at the wp_head action with calls to wp_add_inline_style(). This change was implemented to address issues related to redundant code and bypassing the core’s style enqueuing system.

In other words, yet another smarter and more performant solution made it to WordPress Core 😍


Are you as excited as I am for 6.4, {{ subscriber.first_name | strip | default: “my friend” }}?!


🚀 Performance

  • Lighthouse v11.2 includes an overhaul to the performance category and adds an upgraded score gauge. On hover, ​you can see​ how each performance metric affects the overall performance score.
  • ​Great MySQL optimization​ tips for those of us who want to get the maximum out of our databases.
