WordPress 7.1 brings several miscellaneous block editor changes for developers. The Navigation block no longer propagates font-size to child items to fix CSS compounding issues, with a PHP filter available to restore legacy behavior. The experimental cloneSanitizedBlock and sanitizeBlockAttributes functions are now deprecated in favor of stable versions. The Markdown parser in @wordpress/blocks switches from showdown to marked, following CommonMark/GFM specs. Mobile multi-selection support is added to the paragraph block, shifting editing event handlers to the canvas element. A new disableContentOnlyForTemplateParts editor setting lets themes opt out of content-only editing for Template Parts. Block-level preset CSS classes now use :where() to match root-level specificity, fixing responsive state conflicts. A bug in getEntityRecords() client-side pagination is fixed so non-paginated entities return full collections. The @wordpress/nux package becomes a no-op compatibility shim, and @wordpress/reusable-blocks APIs now log deprecation warnings.
