WordPress 7.1, code-named “Mary Lou,” was released on August 19, 2026. The update introduces new responsive design controls, improved media processing, better collaboration tools, accessibility enhancements, and changes that provide a more consistent editing experience. It also includes more than 310 Core tickets, with over 100 enhancements and more than 180 bug fixes.

For website owners, WordPress 7.1 is a meaningful update. However, as with any major WordPress release, it should be installed carefully—particularly on business websites, online stores, membership platforms, and sites that depend on custom themes or plugins.

What Is New in WordPress 7.1?

WordPress 7.1 focuses on improving everyday content management while expanding the tools available to designers and developers.

Responsive Styling Without Custom CSS

WordPress 7.1 adds more responsive controls directly to the Site Editor. Website owners using block themes can adjust how blocks look on different screen sizes through Global Styles or individual block settings.

The editor also allows users to preview designs at different viewport sizes. Block themes can define custom mobile and tablet breakpoints in theme.json, giving theme developers more control over responsive layouts.

This reduces the need for custom CSS when making common mobile and tablet adjustments. However, it does not remove the need to test pages on real devices. A layout that looks correct in an editor preview may still behave differently on a particular browser or screen size.

After updating, website owners should check:

• Headers and navigation menus
• Multi-column layouts
• Buttons and calls to action
• Forms and checkout pages
• Images, videos, and embedded content
• Text size and spacing on smaller screens

A New Media Editing Experience

WordPress 7.1 replaces the previous inline cropping tool with a dedicated media editor. The updated workflow brings together freeform cropping, predefined aspect ratios, image flipping, precise rotation controls, and metadata editing.

The familiar Crop button remains, but image adjustments are now handled through a more complete and consistent interface.

This should make basic image preparation easier for editors who do not want to use separate image-editing software. Nevertheless, website owners should still optimize very large images before uploading them whenever possible. Uploading unnecessarily large source files can consume storage space and increase backup sizes.

Browser-Based Image Processing

One of the most important performance-related changes in WordPress 7.1 is client-side media processing. Supported image compression, resizing, and thumbnail generation can now run in the uploader’s browser using WebAssembly instead of relying entirely on the hosting server.

This reduces server resource usage during uploads and helps prevent PHP memory-limit errors and timeouts when working with large images. WordPress 7.1 also improves upload reliability through progress indicators and automatic retries when a connection is interrupted.

Media support has also been expanded to include modern formats such as AVIF, HEIC, and HDR gain maps. An optional GIF-to-video conversion feature can produce smaller files than traditional animated GIFs.

These improvements primarily affect the media upload and processing workflow. They do not automatically optimize every image that is already stored in the Media Library, and they should not be treated as a replacement for proper image sizing, caching, or a content delivery network.

Infinite Scrolling in the Media Library

The Media Library grid now uses infinite scrolling by default. Users who prefer the previous paginated experience can change this behavior through their individual user settings.

Infinite scrolling may be convenient for quickly browsing large media collections, but WordPress has acknowledged that it can create accessibility difficulties. Administrators responsible for accessible editorial workflows should ask their users which browsing method works best for them and switch back to pagination when necessary.

Improved Collaboration with Inline Notes

Notes are more flexible in WordPress 7.1. Editors can leave feedback on a specific piece of text instead of attaching every note to an entire block. Notes now support rich-text formatting, links, multiple conversations on the same block, and @mentions that notify collaborators.

Longer conversations can also be collapsed to keep the editing interface manageable. These changes are particularly useful for marketing teams, agencies, publishers, and businesses in which several people review content before publication.

However, real-time collaborative editing did not make it into WordPress 7.1. Teams should not expect several users to edit the same post simultaneously in the same way they might work in a live collaborative document.

New Tabs and Playlist Blocks

WordPress 7.1 introduces two new blocks:

• The Tabs block organizes related information into separate tabbed panels. It can be useful for product specifications, service details, instructions, and compact FAQ-style content.
• The Playlist block groups multiple audio tracks into a single playlist and can display an optional waveform.

These built-in blocks may reduce the need for additional plugins in some cases. Before replacing an existing tabs or audio plugin, however, compare the available features and test the migration on a staging site. Removing a plugin without converting its content correctly could break existing pages.

More Consistent Navigation and Editing

The WordPress admin bar now remains available across the different editors. This provides more consistent navigation when moving between content editing, site design, and other administrative areas.

WordPress 7.1 also makes the post editor fully iframed for all themes. Separating the editing canvas from the main WordPress administration interface prevents admin styles from interfering with the content being edited. It also makes responsive units and media queries behave more predictably inside the editor.

Most website owners will not need to do anything about this architectural change. Developers and owners of sites with custom blocks, editor extensions, or heavily customized administration interfaces should test them carefully. Older extensions that depend on directly accessing the editor’s surrounding document or loading CSS in a particular way may need adjustments.

Accessibility Improvements

WordPress 7.1 includes dozens of accessibility enhancements and fixes across WordPress Core and the block editor. Improvements cover keyboard navigation, focus behavior, contrast, screen-reader support, labeling, post list tables, media controls, and editor interactions.

The release also introduces shared functions for accessible tooltips and improves the accessibility of the new Tabs and Playlist blocks.

Website owners should remember that an accessible content-management interface does not automatically make the public website accessible. Themes, plugins, navigation structures, color choices, alternative text, headings, forms, and published content must still be reviewed.

WordPress 7.1 Performance Improvements

Browser-based image processing is the most visible performance change, but WordPress 7.1 also makes speculative loading easier to configure. Hosting providers and site administrators can control how WordPress prefetches pages through environment variables or constants without creating a dedicated plugin.

Speculative loading can make navigation feel faster by preparing a likely next page before the visitor opens it. It must still be configured appropriately for the website and hosting environment. More aggressive prefetching is not automatically the right choice for every site, especially where pages contain personalized, frequently changing, or resource-intensive content.

The update does not replace the foundations of WordPress performance. Website owners still need:

• A properly configured hosting environment
• Page and object caching where appropriate
• Optimized images and fonts
• A content delivery network when needed
• A lightweight, well-maintained theme
• Regular database and plugin maintenance
• Performance monitoring after significant changes

What Does WordPress 7.1 Mean for Security?

WordPress 7.1 is not presented as a dedicated security release. Therefore, website owners should not interpret the update as a complete security solution or assume that installing it will protect an otherwise poorly maintained website.

Updating WordPress remains important because it keeps the site on the current development and maintenance branch. However, WordPress Core is only one part of a website’s security. Vulnerable plugins, outdated themes, weak passwords, excessive administrator accounts, and insecure hosting configurations can still expose a fully updated website.

A practical WordPress security routine should include:

• Installing the latest stable WordPress maintenance release
• Keeping active plugins and themes updated
• Removing unused or abandoned plugins and themes
• Using strong, unique passwords and multi-factor authentication
• Limiting administrator access
• Maintaining automatic, restorable backups
• Using HTTPS and a web application firewall
• Monitoring login attempts, file changes, and unexpected administrator accounts

WordPress recommends keeping themes and plugins on their latest versions and maintaining regular backups so a site can be restored if an update causes a problem.

What Should Website Owners Do Before Updating?

A major update should follow a controlled process rather than beginning with a click on the production website.

1. Check Theme and Plugin Compatibility

Review the changelogs and support information for your theme and essential plugins. Pay particular attention to page builders, custom blocks, caching tools, security plugins, e-commerce extensions, and plugins that modify the editor.

2. Create a Complete Backup

Back up both the website files and database. Confirm where the backup is stored and how it can be restored. A backup that has never been tested should not be treated as a guaranteed recovery plan.

3. Test WordPress 7.1 on a Staging Site

Create a staging copy and update it first. Test the administration area as well as the public website. Important checks include:

• Creating and editing posts
• Uploading and editing images
• Contact and lead-generation forms
• User registration and login
• Search functionality
• Shopping carts, payments, and order emails
• Membership or restricted content
• Scheduled tasks and third-party integrations
• Mobile layouts and responsive controls

4. Update During a Low-Traffic Period

Once testing is complete, update the production site when traffic and business activity are lower. Avoid making a major update immediately before a promotion, product launch, or other important event.

5. Clear Caches and Monitor the Site

After updating, clear relevant page, server, and CDN caches. Review error logs and monitor the website for failed forms, layout changes, JavaScript errors, unusual resource usage, and slower response times.

What Should Website Owners Avoid?

Do not:

• Update a business-critical website without a recoverable backup.
• Test beta or release-candidate software on a production site.
• Assume every plugin supports WordPress 7.1 without checking.
• Ignore custom blocks or editor extensions after the iframe change.
• Treat browser-based media processing as a complete performance solution.
• Assume a WordPress update replaces a firewall, backups, access controls, or monitoring.
• leave unused plugins and themes installed simply because they are deactivated.
• Make major core, theme, and plugin changes simultaneously without testing.

If a site depends on custom development or a complex combination of plugins, allow time for compatibility testing before completing the production update.

Is WordPress 7.1 Worth the Update?

For most website owners, yes. WordPress 7.1 delivers useful improvements to responsive design, media management, collaboration, accessibility, and the overall editing experience. Browser-based image processing can also reduce the demands placed on the server during media uploads.

The update should still be approached as a major software change. Back up the website, test it in staging, confirm theme and plugin compatibility, and monitor important functions after deployment. With the right preparation and a hosting environment optimized for WordPress, website owners can take advantage of WordPress 7.1 without introducing unnecessary risk.
