Accessibility
Along with performance, lots of work has focused on improving accessibility in various parts of the WordPress software.
The Block Editor updates bring new functionality, fixes, and more:
The ability to bundle multiple Style variations for block themes.
The option to create page content patterns that users can choose from to create their pages.
New ancestor property in block.json letting one restrict where users can place their blocks.
A new block locking UI with a lock attribute for every block.
Registration of blocks from within themes.
Improved support for preserving unrecognized content in the editor.
More robust block theme export feature in the Site Editor.
Block markup updates for image, quote, list, and group blocks.
New set of Post Comments blocks, No Results block, and more.
& more!
Of note, if you currently have the Gutenberg plugin active on your website and are upgrading to WordPress 6.0, please make sure Gutenberg is updated to its latest version. This helps ensure the best experience possible.
In WordPress 6.0 wp_cache_*_multiple API becomes a full CRUD. Also, option to flush the runtime cache without flushing the entire persistent cache is being enabled.
Taxonomies received a lot of performance improvements, from term query caching and adding limits to taxonomy queries, through navigation menu items to changing term_exists to use get_terms().
This new release offers a streamlined way for theme authors to work with patterns, support for multiple theme.json files AKA style variations, better export themes with Site Editor, and a few more goodies.
Allow block themes to be activated without index.php
This change removes the requirement for block themes to have an unused index.php template just for activation, as they use a templates/index.html file instead. (#54272)
Correct the logic for displaying a _doing_it_wrong() notice for add_theme_support( ‘html5’ )
Calling add_theme_support( 'html5' ) without passing an array of supported types should throw a _doing_it_wrong() notice: “You need to pass an array of types”.
If the second parameter is not specified, it should fall back to an array of comment-list, comment-form, and search-form for backward compatibility.
If the second parameter is not an array, the function should return false.
With 6.0 WordPress installs with more than 10,000 users, so called “large sites”, will receive performance improvements for querying and counting users.
Administration: Add a media_date_column_time filter to the media list table date column. Similar to the existing post_date_column_time filter in the posts list table, this change adds a new hook to filter the “Date” column output in the media list view. (#42942)
Build: Update webpack to v5.x. This aligns closer with how the Gutenberg plugin handles WordPress packages. Enable React Fast Refresh support to WordPress core for block development with @wordpress/scripts. Bring caniuse-lite to the latest version which ensures that build tools target the most recent version of browsers supported by WordPress. (#51750, see #55505)
Build/Test Tools:
A .git-blame-ignore-revs file has been added to the repository with a curated list of “pinking shear” commits (ones only applying stylistic changes), making the blame feature on GitHub much more useful (#55422)
Webpack and all related build processes/scripts have been updated to version 5 (#51750).
The npm install command has been fixed for contributors using an Apple M series silicone by updating the grunt-contrib-qunit dev dependency (#52690).
Bundled Theme: If you’ve been having problems with order of elements in comment form in Twenty Nineteen theme, there’s a good news for you in #46600. It’s fixed!
Canonical: Function redirect_guess_404_permalink() includes all public statuses, rather than just publish, in 404 redirects in its search. (#47911)
Comments: Speeding up Dashboard and Comment moderation SQL load – (#19901)
Emoji: Update the Twemoji to version 14.0.2. This version introduces support for the latest Emoji added in Emoji 14. (#55395)
Update jQuery Color to 2.2.0. Removes bundled version (still existed within core), in favor of expanding the Grunt build steps to include the package from NPM instead. (#55016)
Upgrade PHPMailer to version 6.5.4. The latest release includes some minor PHP cross-version improvements and a safeguard against hosters disabling security functions. Note to hosting providers: don’t disable escapeshellarg() and escapeshellcmd(); it’s not safe! Release notes: https://github.com/PHPMailer/PHPMailer/releases/tag/v6.5.4 (#55187)
Update sodium_compat to v1.17.1. The latest version of sodium_compat includes further improvements for PHP 8.1 compatibility. (#55453)
Update backbone from 1.4.0 to 1.4.1., underscore from 1.13.1 to 1.13.2, and clipboard from 2.0.8 to 2.0.10. (#55547)
Formatting:
Add support for formatting sizes as PB, EB, ZB, and YB. (#40875)
KSES: Add support for <ruby> and related elements. This is especially commonly used in Japanese content, but it can also been seen in content of other languages like Chinese. The set of elements to enable such functionality consists of <ruby>, <rt>, and <rp> in the HTML Standard, while some browsers (like Firefox) additionally support <rb> and <rtc> for more advanced formatting. (#54698)
KSES: Allow lang, xml:lang, dir attributes globally. Globally permit the lang, xml:lang, and dir attributes on all elements rather than a subset in accordance with the HTML specification. (#54699)
Function get_the_author_link() is going to be pluggable in WordPress 6.0. A new filter, get_the_author_link, is added for altering author link output. (#51859)
I18n:
List item separator should be a WP_Locale property (#39733)
Allow languages path in register_block_type (#54797)
Media:
Remove attachment_fields_to_save filter and deprecate image_attachment_fields_to_save(). This filter prevented removing attachment titles. This changeset removes the filter and deprecates the related function since it is no longer used. (#39108)
Enable edits to custom image sizes. With a new filter edit_custom_thumbnail_sizes users will be able to apply media edits to individual custom image sizes. (#28277)
Network/Sites: Improve cache key generation in WP_Site_Query (#55462)
Plugins:
Introduce the plugin_install_description filter. This allows for modification of the plugin card description on the Add Plugins screen. (#55480)
Convert apply_filters() into a proper variadic function. (#53218)
Posts, Post Types: Pass the $update parameter to wp_insert_post_data and wp_insert_attachment_data filters. This makes it easier to determine in a callback function whether this is an existing post being updated or not. (#46228)
Posts, Post Types; Taxonomy: Translate default labels once. Improve the translation of post type and taxonomy labels by caching the translations during runtime. (#26746)

Block Editor
The block editor moves onward with regular releases. GutenbergGutenbergThe Gutenberg project is the new Editor Interface for WordPress. The editor improves the process and experience of creating new content, making writing rich content much simpler. It uses ‘blocks’ to add richness rather than shortcodes, custom HTML etc. https://wordpress.org/gutenberg/ version 10.7 is bundled with WordPress 5.8; that totals eight Gutenberg releases (versions 10.0, 10.1, 10.2, 10.3, 10.4, 10.5, 10.6, and 10.7) all merged into this WordPress release (as the related Gutenberg handbook page makes clear)! Bug fixes and performance improvements from Gutenberg versions 10.8 and 10.9 are also part of 5.8.
As well, those recommendations integrate with the Pattern Directory on WordPress.orgWordPress.orgThe community site where WordPress code is created and shared by the users.

You can now make authenticated requests to various WordPress APIs via the newly-introduced, user-specific, application passwords.
The integration guide includes the application password format, the application password data store, how to generate credentials manually or programmatically through the REST API, and how to use those credentials with the REST API or XML-RPC API. Additionally, you’ll notice highlights on future developments for the REST API.
The #core-auto-updates team introduces a new UIUIUser interface allowing website administrators to opt-in to major version automatic updates. Read on to learn more about the new user interface to opt-in to automatic updates for major versions looks, how the user interface works, and how you can extend the core major versions auto-updates feature.
The block editor continues its rapid iteration. GutenbergGutenbergThe Gutenberg project is the new Editor Interface for WordPress. The editor improves the process and experience of creating new content, making writing rich content much simpler. It uses ‘blocks’ to add richness rather than shortcodes, custom HTML etc. https://wordpress.org/gutenberg/ version 9.2 is bundled with WordPress 5.6; that’s seven Gutenberg releases (versions 8.6, 8.7, 8.8, 8.9, 9.0, 9.1, and 9.2) all bundled into this release (and as noted in the related Gutenberg handbook page)! Bug fixes and performance improvements from Gutenberg versions 9.3 and 9.4 are also part of 5.6.
The WordPress 5.6 Beta 1 post highlights many new features and improvements. There is improved support for video positioning in cover blocks, enhancements to Block Patterns including translatable strings, character counts in the information panel, improved keyboard navigation, and improved UI for drag and drop functionality.
Included below are details on a new Block API version that enables blocks to render their own block wrapper element, and a new createBlocksFromInnerBlocksTemplate Block API to create blocks from the InnerBlocks template. You’ll notice new block supports and abilities for dynamic blocks to use the new block supports, accessibilityAccessibilityAccessibility (commonly shortened to a11y) refers to the design of products, devices, services, or environments for people with disabilities.

That’s because jQuery Migrate is tentatively planned to be removed in WordPress 5.7 or later depending on testing. As 5.6 includes a major upgrade to the jQuery library, please ensure you test your plugins and themes as thoroughly as possible before the release of WordPress 5.6 to avoid any preventable breakage.
The next major version release of PHP, 8.0.0, is scheduled a few days prior to WordPress 5.6. The WordPress project has a long history of being compatible with new versions of PHP as soon as possible, and this release is no different. Because PHP 8 is a major version release, changes that break backward compatibility or compatibility for various APIs are allowed. While all of the detectable issues in WordPress can be fixed, you will need to verify that all of your plugins and themes are also compatible with PHP 8 prior to upgrading. Read on for more detailed information about what to look for.
