What’s inside

This momentous release opens new possibilities for the creative expression of designers, creators, and builders. Powerful tools and refined controls give users confidence and allow them to easily manage their sites.

Add pages, browse style variations, create synced patterns, and enjoy fine-tuned control over navigation menus. Spend less time switching across different site areas—so you can focus on what matters most. Creation to completion, all in one place.

Create and sync patterns

Arrange blocks and save them to the ‘My Patterns’ section for use throughout your site. You can even specify whether to sync your patterns (previously referred to as “Reusable blocks”) so that one change applies to all parts of your site. Or, utilize patterns as a starting point with the ability to customize each instance.

Work faster with the Command Palette

Switch to a specific template or open your editor preferences with a new tool that helps you quickly access expanded functionality. With simple keyboard shortcuts (⌘+k on Mac or Ctrl+k on Windows), clicking the sidebar search icon in Site View, or clicking the Title Bar, get where you need to go and do what you need to do in seconds.

Sharpen your designs with new tools

New design controls bring more versatility for fine-tuning, starting with the ability to customize your captions from the Styles interface without coding. You can manage your duotone filters in Styles for supported blocks and pick from the options provided by your theme or disable them entirely. The Cover block gets added settings for text color, layout controls, and border options, making this powerful block even more handy.

Accessibility remains a core focus

Incorporating more than 50 accessibility improvements across the platform, WordPress 6.3 is more accessible than ever. Improved labeling, optimized tab and arrow-key navigation, revised heading hierarchy, and new controls in the admin image editor allow those using assistive technologies to navigate more easily.

Other highlights

Specify your aspect ratios and ensure design integrity, especially when using images in patterns.

Build your site distraction-free

Distraction-free designing is now available in the Site Editor.

Rediscover the Top Toolbar

A revamped Top Toolbar offers parent selectors for nested blocks, options when selecting multiple blocks, and an interface embedded into the title bar with new functionality in mind.

List View improvements

Drag and drop to every content layer and delete any block you would like in the updated List View.

Build templates with Patterns

Create unique patterns to jumpstart template creation with a new modal enabling access to pattern selection.

Changes in PHP support

Looking toward the future

20 years ago this past May, WordPress shipped the very first version, 0.7. What started with a blog post from co-founder Matt Mullenweg and a subsequent comment by co-founder Mike Little eventually evolved into the world’s most popular web publishing platform.

WordPress software continues to evolve and iterate based on the needs and desires of its robust and diverse user community. This release is the capstone of Phase 2 along the WordPress development roadmap. As the community looks to the future, all efforts turn to 6.4 and, subsequently, the transition into Phase 3, which is expected to introduce powerful collaboration tools to the website creation and management experience.
