WordPress 7.1, named "Mary Lou" after jazz pianist Mary Lou Williams, was released on August 19, 2026. It is the second major release of the year, three months after WordPress 7.0. The update focuses on responsive design controls, collaboration inside the editor and media handling, and it adds two core blocks, Tabs and Playlist, for features many sites currently get from plugins.
What is new in WordPress 7.1
The official announcement lists these main changes:
- Responsive styles. Blocks can be styled differently for different screen sizes without custom CSS, and theme.json gains responsive and pseudo-state options.
- Admin bar in every editor. Navigation stays consistent across all editing screens.
- A new media editor. One tool handles freeform or aspect-ratio cropping, flipping and rotation, with browser-based image processing and native support for AVIF, HEIC and HDR formats.
- Richer Notes. Inline notes now support mentions and rich text, so editorial feedback can stay inside WordPress.
- New blocks. Playlist, for audio collections with waveforms, and Tabs, for tabbed content.
- Interactive button styles for hover, focus and active states.
For developers, the SVG Icon API is now public, the Abilities API introduced in 7.0 gained enhancements, and a new Design System supports admin interface theming. WordPress.org credits more than 800 contributors, including more than 170 first-time contributors, with over 1,500 enhancements and fixes.
Managed hosts moved quickly. Pantheon's release note confirms that WordPress 7.1 was available on its platform on August 19, 2026. WPBeginner's coverage reports that WordPress 7.2 is already scheduled for December 9, 2026.
Why it matters for companies hiring IT firms
Responsive styles in core can reduce the amount of custom CSS a site needs, which matters when you pay for design changes or move between agencies. The Tabs and Playlist blocks may let you retire plugins that only provided those features, which lowers update and security overhead. The new image formats help image-heavy sites, but test how your theme and CDN handle AVIF and HEIC files before relying on them.
If your site was built by a WordPress development company, ask whether its custom blocks and theme.json settings conflict with the new responsive controls, and whether any plugins can now be removed.
Collaboration features matter too. Notes with mentions and rich text let marketing teams, editors and outside writers leave feedback on drafts inside WordPress instead of sending screenshots and documents back and forth. If several people or an agency work on your content, agree how notes will be used so that review comments are not lost when content is published.
Why it matters for IT firms
Two major releases within three months, with 7.2 planned for December, mean agencies need a repeatable update and regression process rather than one-off upgrades. Firms that sell responsive website design can now deliver more device-specific layouts through the editor, which changes how much custom CSS work is needed and how much clients can maintain themselves. The public SVG Icon API and the new admin Design System are worth testing for agencies that build custom admin experiences.
What to do next
- Update a staging copy first and check custom blocks, theme.json styles and any page builder layouts.
- List plugins that only provide tabs, audio playlists or image cropping, and decide whether core features can replace them.
- Agree a schedule with your agency for the 7.2 cycle in December so updates are planned rather than reactive.
- Apply minor security releases promptly. The WordPress releases page shows that 7.1 has already received three point releases.
