WordPress 7.1, code-named “Mary Lou” after jazz pianist and composer Mary Lou Williams, was released by the WordPress project on August 19, 2026. The headline features are responsive styling without custom CSS, a new media editor and upgraded Notes for editorial teams. The latest maintenance release in the branch is WordPress 7.1.4, published on October 28, 2026 and tagged as a security release, so any site still running an earlier 7.1 version should update.
What changed in WordPress 7.1
The biggest change for site owners is responsive styling. In WordPress 7.1, you can set how blocks look at different screen sizes from Global Styles or from an individual block’s settings, and the official release notes say no custom CSS is needed. Buttons also gain styles for hover, focus and active states.
Media handling has been reworked. A new media editor modal replaces the old inline cropping tool and brings freeform and aspect-ratio cropping, flipping, rotation and metadata editing into one place. Image compression, resizing and thumbnail generation can now run in the browser through a WebAssembly build of libvips, which reduces load on the server. The release also adds native AVIF, HEIC and HDR gain map support, opt-in conversion of GIFs to video, and infinite scrolling as the Media Library default.
Notes, the in-editor commenting feature, now supports rich text and @mentions, can be attached to specific text rather than a whole block, and can be collapsed. Two new blocks arrive: Playlist, for multiple audio tracks, and Tabs, for content organized into tabbed panels. The admin bar now stays visible across all editors, and new accessible tooltip functions extend to more admin screens. WordPress says more than 800 people contributed to the release, including over 170 first-time contributors, with more than 1,500 enhancements and fixes.
Why it matters for businesses
For small and mid-size businesses, responsive styling is the practical win. Many sites look fine on desktop but need a developer to fix spacing, font sizes or layouts on phones. Moving those controls into the editor means marketing teams can adjust mobile layouts themselves, as long as the theme supports the block editor and Global Styles. Classic themes and page builders may not benefit in the same way.
The media changes affect speed and hosting costs. Processing images in the browser takes work off shared or entry-level hosting, and support for modern formats such as AVIF can mean smaller files. Smaller images and fewer server bottlenecks help page speed, which in turn supports search rankings and conversions.
Notes with mentions and text-level comments make WordPress more workable for teams that review content before it goes live, such as agencies, regulated businesses and companies publishing in more than one language across the US, EU, GCC or India. Fewer review cycles in email or shared documents means faster publishing.
The caution is compatibility. Major releases can break plugins and custom themes, so updates should go through a staging site first. With WordPress 7.2 already in beta, the release cycle is not slowing down, and businesses benefit from a regular, tested update routine rather than large, risky jumps.
What to do now
- Check your version under Dashboard > Updates and move to WordPress 7.1.4, the latest security release in the 7.1 branch.
- Test updates on a staging copy first, especially if you rely on caching, page builder or ecommerce plugins.
- Confirm your theme supports Global Styles, then review your key pages on mobile and fix layout issues with the new responsive controls.
- Re-check image settings: test the new media editor, and confirm your optimization plugin works alongside browser-based image processing.
- Set up Notes for content review so editors and approvers can comment directly on specific text.
- If your site is on a classic theme or an old page builder, plan a move to a block-based build. Our website redesign checklist explains how to do it without losing SEO.
