WordCamp US 2026 opens its doors tomorrow, August 16, in Phoenix, Arizona — and the timing couldn’t be more exciting for the WordPress developer community. The flagship annual event runs August 16–19, and WordPress 7.1 is scheduled to ship on the very last day, making this year’s closing session a live release event.
WordPress 7.1 Launches August 19 — Live at WordCamp US
The feature set for WordPress 7.1 is locked, RC3 landed on August 12, and the dry run is scheduled for August 18 — one day before the public release. If you’re attending WordCamp US in Phoenix, you’ll get to watch the release happen in real time. If you’re not, you’ll want to have your update plan ready.
Key Developer Features Shipping in WordPress 7.1
Responsive Block Styles — Finally in Core
One of the most anticipated features for theme developers lands in 7.1: responsive block styles. You can now define styles for tablet and mobile viewports directly in theme.json using @mobile and @tablet keys. Themes can also configure their own breakpoints via the new settings.viewport property. No more CSS workarounds — responsive design is now a first-class block editor feature.
Pseudo-State Styling (:hover, :focus, :active)
WordPress 7.1 adds support for :hover, :focus, :focus-visible, and :active states in theme.json and the editor — starting with the Button and Navigation Link blocks. Theme authors can now define interactive states without writing custom CSS.
SVG Icon API Goes Public
The SVG Icon API introduced in WordPress 7.0 is now a proper public API. Register icon collections with wp_register_icon_collection(), add icons with wp_register_icon(), and render them anywhere in PHP with wp_get_icon(). Plugin authors can now ship branded icon sets that integrate natively with the editor’s Icon block.
The Post Editor Is Always Iframed
The post editor completes its transition to always-iframed in 7.1 — regardless of theme type, block API versions, or whether legacy meta boxes are registered. The conditional switching between iframed and non-iframed modes is gone. If your plugin or theme accesses the global document or window to interact with the editor canvas, now is the time to fix it.
Abilities API: From Foundation to Toolkit
The Abilities API — WordPress’s framework for AI integrations and automation tooling — picks up a filterable execution lifecycle, custom validation, and a shared discovery pipeline in 7.1. If you’re building AI-powered plugins or protocol adapters, this is the release where the API becomes genuinely useful.
React 19 Punted Again
React 19 will not ship in WordPress 7.1. It was briefly enabled in Gutenberg, then reverted after unexpected incompatibilities surfaced. WordPress 7.1 stays on React 18.3. Testing continues via an experimental flag in Gutenberg settings — but plugin developers should audit their code now for bundled react/jsx-runtime and any removed React 19 features like string refs.
What Didn’t Make 7.1
- Real-time collaboration — not in 7.1
- React 19 — punted again
- Hiding the Classic block from the inserter — reverted
- The “On This Day” dashboard widget — didn’t land
WordCamp US 2026: What to Watch
Beyond the 7.1 launch, WordCamp US is the biggest gathering of WordPress contributors, developers, and community members of the year. Sessions run August 16–19 in Phoenix, with the contributor day and the live release event as the bookends. If you can’t attend in person, the WordPress.org team typically streams key sessions.
Key Takeaway: WordPress 7.1 is a developer-heavy release — responsive styles, pseudo states, a public SVG Icon API, and a fully iframed editor are all shipping. With WordCamp US starting tomorrow and the release landing on closing day, this is a week to pay close attention.
