WordPress 6.5 Release Guide (Historical Archive)

Historical release guide, verified July 18, 2026. WordPress 6.5 “Regina” was released on April 2, 2024 and named for jazz violinist Regina Carter. It is no longer the current WordPress version.

Font Library

WordPress 6.5 introduced the Font Library for block themes. Site administrators could install, remove, and manage fonts from the editor, including local font files and supported Google Fonts, without relying on theme-specific controls.

Design and editing improvements

The release expanded revisions for styles, templates, and template parts. It also added more background-image controls, Cover block improvements, shadow controls, smoother drag-and-drop behavior, and improved link controls.

New table and grid Data Views made pages, templates, patterns, and template parts easier to browse and manage inside the Site Editor.

Developer features

• Interactivity API: a standardized foundation for interactive block front ends.
• Block Bindings API: a way to connect supported block attributes to custom fields and other data sources.
• Plugin dependencies: the Requires Plugins header allowed plugins to declare required dependencies.
• Appearance tools: additional design capabilities became available to classic themes that opted into them.
• AVIF support: WordPress gained support for the AVIF image format where the server image library supports it.

Performance and accessibility

The official release announcement reported more than 110 performance updates. Compared with WordPress 6.4, the editor loaded more than twice as fast and input processing was reported as up to five times faster. Translated sites could load up to 25% faster. The release also included more than 65 accessibility improvements.

These figures describe testing around the 6.5 release and should not be treated as a guarantee for every site. Real performance still depends on hosting, themes, plugins, content, caching, and configuration.

Security and update status

WordPress 6.5 did not introduce a universal firewall, an “ESS” security layer, browser caching controls, WooCommerce themes, or automatic SEO improvements. Those are not core 6.5 release features.

New and production websites should run the latest stable WordPress release and supported plugin, theme, PHP, and database versions—not WordPress 6.5. Back up the site and test compatibility before major updates.
