WordPress 7.1 “Mary Lou”: What’s New and Why You Should Upgrade
WordPress 7.1, officially code-named “Mary Lou,” arrived on August 19, 2026, bringing some of the most anticipated updates to the site-building experience. This major release introduces game-changing responsive design controls, a massive overhaul to media handling, and powerful collaboration tools that eliminate the need for several third-party plugins.
Whether you are a developer, a content creator, or a site owner, here is a complete guide to everything new in WordPress 7.1 and why making the jump to the latest version is a smart move.
What’s New in WordPress 7.1?
1. Responsive Styling Without Custom CSS
For a long time, adjusting how blocks looked on mobile versus desktop required extra plugins or custom CSS. WordPress 7.1 changes this by introducing native responsive styling. Inside the Site Editor, you can now apply different styles for desktop, tablet, and mobile screens directly to compatible blocks. You can effortlessly tweak typography, padding, margins, and layouts—like shrinking a large heading for mobile devices or reducing padding on smaller screens—all without writing a single line of code.
2. Interactive Button States (Hover & Focus)
WordPress 7.1 brings interactive style states directly into the editor, heavily focusing on Button blocks. You can now easily configure native hover, focus, and active states for your buttons. This gives you the power to create dynamic, engaging calls to action without relying on complex stylesheets.
3. Smarter Media Handling and Client-Side Processing
The media workflow received a massive upgrade in this release:
- Client-Side Processing: Media compression, resizing, and thumbnail generation now happen directly in your browser using WebAssembly before the file is even uploaded to the server. This drastically reduces server strain and prevents PHP timeouts when uploading large files.
- Modern Format Support: WordPress 7.1 includes built-in support for HEIC (the default format for iPhone photos), UltraHDR, AVIF, and WebP. You no longer need a converter plugin to upload images straight from your phone.
- GIF-to-Video Conversion: Animated GIFs can now be automatically converted into video formats upon upload, significantly reducing file sizes.
- Dedicated Media Editor: The old inline crop tool has been replaced by a full editing modal that combines aspect-ratio presets, freeform cropping, flip and precise rotation controls, and metadata editing in one fluid workflow.
- Infinite Scrolling: The Media Library grid now features automatic infinite scrolling, saving you from having to repeatedly click “Load more”.
4. New Native Tabs and Playlist Blocks
Say goodbye to additional plugins for basic content organization. WordPress 7.1 introduces two highly requested native blocks:
- Tabs Block: Perfect for product specifications, pricing plans, or FAQs, this block lets you organize related information into clickable, tabbed panels to keep your pages clean and concise.
- Audio Playlist Block: This block allows you to group multiple audio files into a single, cohesive playlist complete with an optional waveform display, which is excellent for podcasts, music samples, or audio lessons.
5. Advanced Collaboration with Upgraded Notes
If you work with a team, the upgraded Notes feature will streamline your editorial workflow. You can now highlight specific text to leave an inline note rather than commenting on an entire block. Notes now support rich-text formatting (bold, italics, links) and multiple conversation threads on the same block. Most importantly, you can now use @mentions to tag team members, which automatically triggers an email notification to alert them.
6. A Refined Admin Experience
Navigating the backend of your site is smoother than ever. The admin toolbar is now persistent, meaning it stays visible across the Site Editor and Block Editor instead of disappearing while you work. Additionally, the Command Palette has been improved, and the Posts list view now displays short excerpts so you can identify content at a glance.
Why Should You Upgrade to WordPress 7.1?
Upgrading to WordPress 7.1 isn’t just about getting new features; it’s about making your website faster, safer, and easier to manage:
- Faster Performance: Client-side media processing offloads heavy tasks to the browser, significantly reducing the load on your web server and improving overall site speed.
- Fewer Plugins Required: With native tabs, playlists, responsive styling, and HEIC support, you can remove bloated third-party plugins that slow down your site and pose security risks.
- Better SEO and Accessibility: Built-in mobile responsiveness and dozens of accessibility enhancements across the editor ensure your site is optimized for both search engines and all your visitors.
- Enhanced Security: Running the latest version of WordPress is the single best way to protect your site from vulnerabilities. Every major release includes critical security patches.
