Quick summary: WordPress’s August update, version 7.1 “Mary Lou,” adds responsive block styling with no custom CSS, browser-based image compression, and two new content blocks. WordPress also released its first official browser extension and signed a public letter on AI policy. None of it requires action from you right now — but it’s worth knowing what’s coming down the pipe.
WordPress had a busy August. A new major release, a brand-new browser extension, and a public stance on AI policy — that’s a lot to land in one month. Here’s the rundown, no fluff.
WordPress 7.1 “Mary Lou”: Responsive Editing Without Custom CSS
The big one: responsive styling is now built right into the editor. You can set how a block looks on phone, tablet, and desktop straight from Global Styles or the block’s own settings — no custom CSS needed. If a client’s ever asked you to make a heading smaller on mobile and you groaned at the thought of touching a stylesheet, this update is aimed right at that.
Faster Image Handling Means Real WordPress Performance Optimization
Image handling got smarter too. Compression, resizing, and thumbnail generation now happen in the visitor’s browser instead of on your server — a real piece of WordPress performance optimization most site owners will never notice happening, except that things feel faster. WordPress also added native support for AVIF, HEIC, and HDR gain map formats, so photos straight off an iPhone or a modern camera just work — no converting first.
This kind of under-the-hood speed work is exactly what we handle for you as part of our managed WordPress hosting service — one less thing you have to think about when an update like this rolls out.
A couple of small but handy additions round out the release: a Playlist block for organizing audio tracks, and a Tabs block for splitting content into panels. Both used to mean installing a plugin. Now they’re just there.
There’s also a quiet fix that matters more than it sounds: the admin bar stays put as you move between editors instead of flickering in and out, and the post editor is now fully “iframed” on every theme — which should mean fewer weird style clashes between your theme and the editor.
A New Official WordPress Browser Extension
WordPress also shipped its first official browser extension, for Chrome (and Chromium browsers) and Safari on macOS. It solves a small, familiar annoyance: the admin bar is useful, but it eats screen space and can clash with sticky headers.
The extension lets you hide the admin bar — on one site or everywhere — while keeping your go-to shortcuts a click away. It also adds a couple of developer extras: a way to see block boundaries on the page, and a cache-busting reload button, so you’re never stuck wondering if you’re looking at a stale cached version of your own site. It’s open source, so expect it to keep gaining features.
WordPress Signs Onto an AI Policy Letter
The quieter but arguably bigger news: WordPress signed the “Open Weights and American AI Leadership” letter, alongside 270+ other companies including Automattic and GoDaddy. It asks US policymakers to expand computing access for startups and researchers, invest in shared resources like public datasets, and keep AI development spread across many players instead of a handful of closed systems.
It tracks with WordPress’s whole identity. Executive Director Mary Hubbard put it simply: the next wave of innovation won’t come from models alone — it’ll come from people building with them. Same open-source argument that built WordPress, now pointed at AI.
What This Means If You Just Run a Small Business Site
You don’t need to do anything about most of this right away — updates roll out gradually, and a good managed WordPress hosting provider handles the upgrade path for you. But it’s worth knowing where things are headed: faster, more visual editing with less custom code, lighter image handling, and a platform positioning itself to stay relevant as AI tools get baked into more of the web-building process.
If you’re not sure whether your site’s already on 7.1, or whether updating will break something you’ve customized, that’s exactly the kind of thing worth checking before you hit “update” and hope for the best. Grab a free site audit, and I’ll tell you where things stand.
