WordPress 5.3 is shaping up to be the best WordPress yet! Users will see new blocks, more intuitive blockBlockBlock is the abstract term used to describe units of markup that, composed together, form the content or layout of a webpage using the WordPress editor. The idea combines concepts of what in the past may have achieved with shortcodes, custom HTML, and embed discovery into a single consistent API and user experience. editor interactions, improved media handling, improved accessibilityAccessibilityAccessibility (commonly shortened to a11y) refers to the design of products, devices, services, or environments for people with disabilities. 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…
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.
PHP 7.4 & Code Modernization
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.
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.
Other Developer Updates
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. The semantic scripting language primarily used for outputting content in web browsers. structure, changes to wp_die() HTML output, expansion of the options available to compare_key so that developers have access to metaMetaMeta is a term that refers to the inside workings of a group. For us, this is the team that works on internal WordPress sites like WordCamp Central and Make WordPress.-key comparison operators similar to those available for meta values, updates related to bumping the Backbone version bundled with WordPress from v1.3.3 to v1.4.0 and other external library updates, dropping support for integer menu slugs, addition of a “Show” button next to the password field on the login screen, passing arrays to supports argument when registering post types, HTML5 support for script and style arguments, recording additional information for saved queries, unit-less CSS line-height values, updates to cores’ build/test tools, and more!
