WordPress 6.6 "Dorsey" shipped on July 16, 2024. It is the release where the block editor — default for years now — finally becomes a real tool for designers, not a perpetual training ground. Here is what changes for site builders.
Section styles
Section styles let you define named styles for groups of blocks. Concretely: instead of applying colours and typography block by block, you define a "Inverted hero" or "Soft card" style in theme.json and apply it to the group. The result is visual consistency even when editing is done by non-technical users.
This is the missing piece that makes the block editor manageable on projects with ten similar pages. We are already adopting it as default for new themes.
Overrides in synced patterns
Synced patterns (formerly reusable blocks) were powerful but rigid: change one instance, change them all. In 6.6 specific fields can be marked "overridable" — the editor can change text or image in a specific instance without detaching it from the pattern. A real shift: you can now build a library of company patterns and let editors fill them autonomously.
View transitions API
The Site Editor starts leveraging the browser View Transitions API for internal navigation. For sites using block themes, page transitions become smooth with no JavaScript. Works well on Chromium, partially on Safari, coming on Firefox. Not an SPA replacement: it is progressive enhancement.
Other notable bits
- Negative aspect ratios on images: handy for artistic layouts.
- Block Bindings API more stable: linking a block to a custom field or post meta becomes straightforward, no more obscure PHP filters.
- Performance: noticeably faster block editor load, especially on sites with many custom blocks.
What not to expect
The block editor is still not the answer for every client. If the end editor is a journalist who needs a headline and a paragraph, the classic editor is still faster. If instead the client wants to compose landing pages, work with patterns and maintain a design system, 6.6 is the first release where we say "yes, it makes sense" without hesitation.
Plugin compatibility
Like every major release, some plugins suffer. Those that hijack the editor (page builders like Elementor or Bricks) may need updates. Our rule: upgrade staging, observe for two weeks, then promote. Never on release day.
