Overview
WordPress 7.1 is a major release in the 7.x series that meaningfully improves the editing experience, responsive design, media handling, and collaboration tools. This release is code‑named “Mary Lou,” honoring pioneering jazz pianist, arranger, and composer Mary Lou Williams, continuing WordPress’s tradition of naming major releases after influential musicians.
As a major release, 7.1 introduces new features, workflows, and changes that affect day‑to‑day use. It builds on the foundation of 7.0 with updates aimed at making content creation and site management easier for everyday users and teams.
Release Date
WordPress 7.1 was released on August 19, 2026, coinciding with the final day of WordCamp US in Phoenix.
New Features
Responsive Styling Built Into the Editor
You can now control how blocks behave at different screen sizes directly in the editor. This includes responsive styles for both Global Styles and individual blocks, making it easier to design layouts that adapt across devices.
Custom Breakpoints
Theme developers can define custom mobile and tablet breakpoints in theme.json, giving more control over how content responds to different screen widths. These values use px, em, or rem units and affect both responsive styling and block visibility.
Updated Media Editor
The Crop button now opens a dedicated media‑editing modal with freeform cropping, aspect‑ratio cropping, flipping, rotation, and metadata editing. It’s a cleaner, more complete workflow for anyone who works with images.
Admin Bar Consistency
The Admin Bar now stays visible across all editors, giving you consistent navigation whether you’re writing a post or editing your site’s design.
Notes With Rich Text and Mentions
Notes now support bold, italic, code formatting, links, and @mentions. You can leave notes on specific text selections, start multiple conversations on the same block, and collapse long notes. This is a big improvement for teams collaborating inside WordPress.
New Blocks: Playlist and Tabs
Two new blocks expand what you can build without plugins:
- Playlist for audio collections (with waveform visualization)
- Tabs for organizing content into structured sections
Custom Icon Sets
Plugin and theme authors can register custom icon sets, making them available throughout the editor via a public SVG Icon API.
Faster Media Uploads
Image compression, resizing, and thumbnail generation now happen in the browser using a WebAssembly build of libvips. This reduces server load and avoids PHP memory limits, especially for large uploads. AVIF, HEIC, and HDR gain map formats are supported.
Interactive Styles
Button and Navigation Link blocks now support hover, focus, and active styles directly in the editor.
Bugs Fixed
WordPress 7.1 includes a long list of bug fixes across the admin experience, block editor, media workflows, and responsive controls. These fixes improve stability, reduce editor inconsistencies, and refine the new features introduced in the 7.x series.
Highlights include:
- More reliable block rendering
- Better responsive previews
- Fixes for media‑editor edge cases
- Improvements to Notes and @mentions
- Smoother Admin Bar behavior across editors
- Updates to block visibility and styling logic
These fixes help ensure the new features work consistently across different hosting environments, themes, and plugin setups.
Security Updates
WordPress 7.1 includes security hardening and patches, though it is not primarily a security release. Major releases typically include updated dependencies, hardening measures, and security‑related refinements to editor and admin workflows. If your site is running 7.0.x, upgrading to 7.1 ensures you receive the latest security improvements along with the new features.
A follow‑up point release (7.1.1) was expected shortly after launch to address early‑reported issues, which is a common pattern after major releases.
Other Important Information
Updated Packages and Assets
WordPress 7.1 includes updates to internal packages and introduces new admin‑area assets such as tooltip styles and updated About page graphics. These changes support the refreshed admin experience and improved editor workflows.
Developer Enhancements
Developers gain access to new APIs, expanded theme.json capabilities (including viewport breakpoints and pseudo‑state styling), updated icon‑registration options, and improved responsive controls. The post editor now loads in a sealed iframe for block themes, improving consistency and isolation.
Performance Improvements
Browser‑based media processing reduces server load, improves upload reliability, and speeds up workflows for sites with heavy media usage. The Media Library also uses infinite scrolling by default, with an option to return to pagination.
Should You Upgrade?
WordPress 7.1 is a major release, so the decision to upgrade depends on your website’s complexity and how mission‑critical it is.
Pros of Updating
- New responsive design tools
- Improved media editing workflow
- Better collaboration features with Notes and mentions
- Faster and more reliable media uploads
- Consistent Admin Bar navigation
- New blocks and expanded customization options
- Security hardening and updated dependencies
- Better long‑term compatibility with themes and plugins
Cons of Updating
- Major releases can introduce compatibility issues with older plugins or custom themes
- Complex ecommerce, LMS, membership, or heavily customized sites may require additional testing
- Some workflows may change, requiring user training or process updates
- Sites without a staging environment or reliable backup process carry unnecessary risk
Best Practices Before Updating
For mission‑critical websites:
- Test the update on a staging site
- Confirm plugin and theme compatibility
- Make a full backup of files and the database
- Review key workflows (checkout, forms, login, search, membership access, course progression)
- Wait a couple of days before updating your live site so early bugs can be identified and patched
Major releases often receive quick follow‑up patches, so giving the ecosystem a short window to stabilize is usually a smart move.
Summary
WordPress 7.1 is a feature‑rich major release that improves responsive design, media handling, collaboration, and overall workflow. If your business relies on WordPress for content delivery, ecommerce, membership, or online learning, these enhancements can make your site easier to manage and more flexible to build on.
