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.

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 JSONJSON JSON, 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.

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.

Block Editor

The block editor has continued its rapid iteration since WordPress 5.0, and now has GutenbergGutenberg The 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.

Privacy Policy and Data Exports

The Privacy component has been enhanced with the addition of four new features to makemake A collection of P2 blogs at make.wordpress.org, which are the home to a number of contributor groups, including core development (make/core, formerly "wpdevel"), the UI working group (make/ui), translators (make/polyglots), the theme reviewers (make/themes), resources for plugin authors (make/plugins), and the accessibility working group (make/accessibility). customizing and designing the Privacy Policy page easier. Tag restrictions for User Data Exports have also been relaxed.

Media Widgets

Not one, not two, but three new media widgets makemake A collection of P2 blogs at make.wordpress.org, which are the home to a number of contributor groups, including core development (make/core, formerly "wpdevel"), the UI working group (make/ui), translators (make/polyglots), the theme reviewers (make/themes), resources for plugin authors (make/plugins), and the accessibility working group (make/accessibility). their way into coreCore Core is the set of software required to run WordPress. The Core Development Team builds WordPress.. It’s like the AV crew just showed up and now the party can really begin. You get an audio widgetWidget A 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. WordPress widgets were originally created to provide a simple and easy-to-use way of giving design and structure control of the WordPress theme to the user.. You get an image widget. You get a video widget. Check under your seat, media widgets for everyone!

Media Widgets for Images, Video, and Audio

 

Fabulously Rich Text Widget

Robin Hood has come to town and is handing out rich text editing to all the text widgets. No more having to manually type out your HTMLHTML HyperText Markup Language. The semantic scripting language primarily used for outputting content in web browsers. in text widgets like it’s 2016.

Addition of TinyMCE to the Text Widget

 

Simpler Link Editing, Streamlined Browser Support, and Editor Instantiation via JSJS JavaScript, a web scripting language typically executed in the browser. Often used for advanced user interfaces and behaviors.

Editing just got a lot easier, you can thank us later. But trust us that adding and managing links within the editor is now easier than ever. If you don’t trust us, then just try navigating in and out of links with your arrow keys. Pretty cool, huh? That’s the new TinyMCE inline element / link boundaries. As for the reduced browser support, let’s just say IE 8, 9, and 10 have been thanked for their service but can feel free to enjoy their retirement. Also, if bootstrapping the TinyMCE content editor dynamically via JS is your thing, then boy are you going to be excited!

Resizing the CustomizerCustomizer Tool built into WordPress core that hooks into most modern themes. You can use it to preview and modify many of your site’s appearance settings. sidebarSidebar A sidebar in WordPress is referred to a widget-ready area used by WordPress themes to display information that is not a part of the main content. It is not always a vertical column on the side. It can be a horizontal rectangle below or above the content area, footer, header, or any where in the theme.

If you have used the Customizer on a high-resolution screen, then you may have noticed that the Customizer sidebar is… suboptimally narrow. The sidebar is now variable width based on screen size to help you receive the best editing experience possible.

AccessibilityAccessibility Accessibility (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): saving the best for last

As a part of ongoing efforts to improve accessibility in WordPress, 4.8 includes some changes to headings within admin screens. This is a continuation of the work started in 4.3 on restoring the H1 (heading level 1) to the admin screens and continued in 4.4 with the introduction of a better headings hierarchy. Also improved is the Tag Cloud widget, now swapping out the title attributes in favor of aria-label attributes.
