Highlights: What’s inside 6.6

Color palettes & font sets

Add more design options to any block theme. Block theme authors can create unlimited individual color or font sets to offer more specific design options within the same theme. These sets provide more contained design possibilities, allowing for customization without changing the site’s broader styling, beyond color or typography settings.

Quick previews for pages

Simplify your workflow with a new layout built for pages. See all of your pages and a preview of any selected page before you edit via a new side-by-side layout in the Site Editor.

Rollbacks for plugin auto-updates

Auto-update your plugins with peace of mind. Enjoy the ease of plugin auto-updates with the safety of rollbacks if anything goes wrong, improving your site’s security while minimizing potential downtime.

Overrides

Add the ability to customize content in synced patterns. Allow specific pieces of content to be customized in each instance of a synced pattern while keeping a consistent style for all instances, simplifying future updates. Currently, you can set overrides for Heading, Paragraph, Button, and Image blocks.

Performance updates

WordPress 6.6 includes important updates like removing redundant WP_Theme_JSON calls, disabling autoload for large options, eliminating unnecessary polyfill dependencies, lazy loading post embeds, introducing the data-wp-on-async directive, and a 33% reduction in template loading time in the editor.

Accessibility improvements

55+ accessibility fixes and enhancements focus on foundational aspects of the WordPress experience, particularly the data views component powering the new site editing experience and areas like the Inserter that provide a key way of interacting with blocks and patterns.
