WordPress 7.1 Launches on Closing Day (August 19)

The headline moment of WordCamp US 2026 arrives on the final day: WordPress 7.1 is scheduled to release on August 19, timed to coincide with the event’s closing. Key developer-facing changes include:

  • Always-Iframed Post Editor — The post editor now always runs in an iframe. Blocks on Block API v2 or lower need updating to v3.
  • Abilities API — A full AI/automation toolkit for developers
  • SVG Icon API — Now public and stable
  • Design System Theming — Arrives for admin UIs
  • React 19 deferred again — Real-time collaboration also not included in 7.1

Also This Week: Next.js 16.3.1 Maintenance Patch Released

While the WordPress world gathers in Phoenix, the Next.js team quietly shipped Next.js 16.3.1 on August 13 — a maintenance-focused patch on top of the major 16.3.0 release from earlier this month. Key fixes include:

  • Turbopack fixes — Multiple stability improvements including async-module runtime fixes, nested promise collapsing in the analyzer, and HMR fixes for dynamic imports evaluated from layouts
  • Next/image fix — Preserves image response after optimization
  • Cache reliability — Discards only cache entries that predate a tag revalidation; reuses completed entries
  • HMR improvements — Dev validation worker stays alive across HMR updates
  • Routing fixes — Optimistic routing bug fixes preventing repeated prefetch loops
  • styled-jsx fix — Restores missing styled-jsx styles in Pages Router SSR on adapter builds
  • Nav Inspector fix — Fixes request loop on repeat captures

If you’re running Next.js 16.3.0, upgrading to 16.3.1 is recommended for improved stability.
