Read it at the original source: ## Questions this post answers ### What breaking change does WordPress 7.1 make to the post editor that could affect my plugin? WordPress 7.1 completes the move to a fully iframe-based post editor, including for sites that register legacy meta boxes. Plugins that rely on reaching across the editor document boundary with JavaScript or CSS need to be reviewed for compatibility, since that boundary is now consistently enforced across all editing contexts. _daily.dev surfaces changes like this for developers auditing plugins before a WordPress upgrade._ ### Does WordPress 7.1 update jQuery UI, and will it break my plugin's styling? Yes, WordPress 7.1 updates the bundled jQuery UI dependency to version 1.14.2. This is flagged as the most notable external library change in the release, and plugins depending on jQuery UI behaviour or styling should be tested against the new version before upgrading production sites. _Track dependency bumps like this jQuery UI update on daily.dev before rolling out a WordPress upgrade._ ### Is infinite scrolling the default behavior in the WordPress Media Library after 7.1? Yes, WordPress 7.1 enables infinite scrolling by default in the Media Library grid, replacing the previous pagination as the default browsing experience. A per-user option still lets someone restore the older paginated behaviour if preferred. _Developers adjusting admin UI expectations after a WordPress release can follow changes like this on daily.dev._ ## Similar posts on daily.dev - [WordPress 6.9 Field Guide](https://daily.dev/posts/wordpress-6-9-field-guide-rt6mfirfj) · Make WordPress Core · 10 upvotes · 0 comments - [What’s new for developers \(July 2026\)](https://daily.dev/posts/what-s-new-for-developers-july-2026--1fusc413s) · WordPress Developer · 10 upvotes · 0 comments --- Tags: [#wordpress](https://daily.dev/tags/wordpress), [#accessibility](https://daily.dev/tags/accessibility), [#rest-api](https://daily.dev/tags/rest-api) [View this post on daily.dev](https://daily.dev/posts/wordpress-7-1-field-guide-dz1vkpsld) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"WordPress 7.1 Field Guide","url":"https://daily.dev/posts/wordpress-7-1-field-guide-dz1vkpsld","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/wordpress-7-1-field-guide-dz1vkpsld"},"datePublished":"2026-08-05T14:47:14.599Z","dateModified":"2026-09-13T19:06:15.033Z","description":"WordPress 7.1 field guide covers all major developer-facing changes in the release, including 310+ Core Trac tickets.
