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.

The concept of accessible design ensures both “direct access” (i.e. unassisted) and “indirect access” meaning compatibility with a person’s assistive technology (for example, computer screen readers). (https://en.wikipedia.org/wiki/Accessibility), and the new Twenty Twenty default theme. Among many goodies in 5.3, developers will love the date/time component improvements, PHPPHPThe web scripting language in which WordPress is primarily architected.

Let’s look at the many improvements coming in 5.3…
Accessibility
Of the 50 updates related to Accessibility in 5.3, you’ll want to particularly note the changes to Admin CSS, improvements of all the media views form controls and changes to explicit labeling, how coreCoreCore is the set of software required to run WordPress.

The block editor has continued its rapid iteration since WordPress 5.0, and now has 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 6.5 bundled with WordPress 5.3; that’s TWELVE releases all bundled into 5.3 (versions 5.4, 5.5, 5.6, 5.7, 5.8, 5.9, 6.0, 6.1, 6.2, 6.3, 6.4, and 6.5)! Bug fixes and performance improvements from Gutenberg versions 6.6 and 6.7 will also be part of 5.3. The Beta 1 post highlights many of the new features and improvements across these releases, but I’ll specifically pull out the reduction in 1.5 seconds of loading time for a particularly sizeable post (~ 36,000 words, ~ 1,000 blocks) as an impressive achievement given all that has otherwise been added to the block editor. The dev notes below also highlight new server-side block style variations APIAPIAn API or Application Programming Interface is a software intermediary that allows programs to interact with each other and share data in limited, clearly defined ways., a new block example API, the Group block, reduced block styles specificity, using class names for text alignment, Columns block classnames, color support for the separator block, an updates to Table and Gallery blocks markup.
Of the 42 updates for Media in 5.3, you’ll want to particularly note the new way to manage big images by detecting them and generating a “web-optimized maximum size” of them as well as saving of image metadata while creating intermediate sizes. Read the dev notes below for more details on the Media component.
MultisitemultisiteUsed to describe a WordPress installation with a network of multiple blogs, grouped by sites. This installation type has shared users tables, and creates separate database tables for each blog (wp_posts becomes wp_0_posts). See also network, blog, site
Of the 15 updates for Multisite in 5.3, you’ll want to particularly note changes to the database, changes to WP_MS_Sites_List_Table, return for short circuits for multisite classes, and improved performance for site and networknetwork(versus site, blog) lookups by ID. Read the dev note below for more details on the Multisite component.
The great news continues. WordPress 5.3 supports PHP 7.4, which is scheduled for release at the end of November! Contributors worked with several external libraries to ensure that all 5 tickets addressing compatibility issues for PHP 7.4 were addressed in time for WordPress 5.3.
In addition to ensuring 5.3 supports PHP 7.4, a handful of updates occurred as a result of the continued coding standards and code modernization efforts. Most notably, the spread operator is now in use where appropriate, and the native PHP JSONJSONJSON, or JavaScript Object Notation, is a minimal, readable format for structuring data. It is used primarily to transmit data between a server and web application, as an alternative to XML. extension is now required to run WordPress.
PluginPluginA plugin is a piece of software containing a group of functions that can be added to a WordPress website. They can extend functionality or add new features to your WordPress websites. WordPress plugins are written in the PHP programming language and integrate seamlessly with WordPress. These can be free in the WordPress.org Plugin Directory https://wordpress.org/plugins/ or can be cost-based plugin from a third-party and theme developers are encouraged to read the following detailed dev notes to fully understand the changes coming and how their code should be updated!
REST APIREST APIThe REST API is an acronym for the RESTful Application Program Interface (API) that uses HTTP requests to GET, PUT, POST and DELETE data. It is how the front end of an application (think “phone app” or “website”) can communicate with the data store (think “database” or “file system”) https://developer.wordpress.org/rest-api/.
Of the 33 updates for the REST API in 5.3, you’ll want to particularly note register array and object metadata, nested response filtering with _fields query parameter, how to set drafts back to “floating date” status, and possibly best of all up to a 30-40% performance increase in large API responses. Read the dev note below for more details on the REST API component.
Of the 31 updates for Site Health in 5.3, you’ll want to particularly note changes to the grading indicator, recovery email enhancements, filters for completed Site Health status tests, and a new Admin email verification screen. Read the dev notes below for more details on the Site Health component.
There are even more goodies in 5.3 like much–needed fixes and a set of improvements to the Date/Time component, changes to prevent search engines indexing sites, new default for links in comments and comment author URLs to use the rel="nofollow ugc" attribute, changes on Twenty Nineteen HTMLHTMLHyperText Markup Language.

Let’s look at the many improvements coming in 5.2…
Site Health and WSOD Protections
WordPress 5.2 includes portions of the Site Health and Servehappy projects. A new Site Health page nested under the “Tools” menu will run a series of tests on a site pointing out potential issues that site owner should be aware of. Plugins and themes may add their own tests, or modify/remove existing ones using filters. More debugging and support information is displayed within an “Info” tab in the same area of the adminadmin(and super admin). This information can help developers troubleshoot user issues.
From the Servehappy project comes the addition that allows administrators to fix or mitigate fatal errors on their site that would previously have been impossible to address without developer interference and modifying the codebase. This includes five ways that developers can integrate with the new recovery mode features.
The block editor has continued its rapid iteration since WordPress 5.0, and now has GutenbergGutenbergThe Gutenberg project is the new Editor Interface for WordPress.

The most significant change in core is the addition of a a reusable block-editor module to expand the usage of the Block Editor in a context independent from the post editor without any dependency to the post object (e.g., to other WordPress admin pages like the widgets screen).
A new asynchronous mode for block rendering has also been added, new RSS and Amazon Kindle embed blocks were added, and a block management modal with the ability to enable/disable blocks from the block inserter. Improvements to the end-to-end tests have been made (including support for aXe Accessibility testing), as well as improvements to the accuracy of WP_Screen::is_block_editor(). Core blocks (aside from the Classic block) are also no longer using TinyMCE under the hood.
Accessibility updates in 5.2 include improvements to markup for Admin tabs, to post formats in list tables, to Admin Bar submenu link markup, and to the Archive WidgetWidgetA WordPress Widget is a small block that performs a specific function. You can add these widgets in sidebars also known as widget-ready areas on your web page.
