UPDATE on 12 July 2021: The Miscellaneous block editor API additions in WordPress 5.8dev notedev noteEach important change in WordPress Core is documented in a developers note, (usually called dev note). Good dev notes generally include a description of the change, the decision that led to this change, and a description of how developers are supposed to work with that change. Dev notes are published on Make/Core blog during the beta phase of WordPress release cycle. Publishing dev notes is particularly important when plugin/theme authors and WordPress developers need to be aware of those changes.In general, all dev notes are compiled into a Field Guide at the beginning of the release candidate phase. was added to the 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.

Whether you are a WordPress website user, builder, or developer, WordPress 5.8 brings exciting changes and a hint of even more goodies coming in WordPress 5.9. But we’re getting ahead of ourselves; let us take a look at what to expect in when 5.8 is released.
In this Field GuideField guideThe field guide is a type of blogpost published on Make/Core during the release candidate phase of the WordPress release cycle. The field guide generally lists all the dev notes published during the beta cycle. This guide is linked in the about page of the corresponding version of WordPress, in the release post and in the HelpHub version page., you will notice what is relevant to you and your users among the many improvements coming in 5.8.
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. This is where you can download the source code for WordPress core, plugins and themes as well as the central location for community conversations and organization. https://wordpress.org/, template editor, theme.json, and blocks in 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. 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. areas among other changes.

Publishing dev notes is particularly important when plugin/theme authors and WordPress developers need to be aware of those changes.In general, all dev notes are compiled into a Field Guide at the beginning of the release candidate phase. below are important details on how theme.json delivers editor style control and associated Global Settings and Global Styles, plus:
Blocks in widget areas
block.json as canonical way to register block styles
deprecation of filters and introduction of context-aware replacements
Removal of previously deprecated EditorGlobalKeyboardShortcuts component, hasUploadPermissions selector, and hidden Subheading block

Amongst all Media changes, the highlight is support for the WebP image format. Accompanied by new image_editor_output_formatfilterFilterFilters are one of the two types of Hooks https://codex.wordpress.org/Plugin_API/Hooks. They provide a way for functions to modify data of other functions. They are the counterpart to Actions. Unlike Actions, filters are meant to work in an isolated manner, and should never have side effects such as affecting global variables and output. (see #52867), it will set foundation for a real performance boost. You will also notice some UIUIUser interface improvements, such as replacing infinite scroll with AJAX response (#50105 and #40330) and copy-link button on media upload screen (#51754).
Changes in the Plugins component aim to make 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 developers lives easier. From better docs search (#50734) and standardizing hooksHooksIn WordPress theme and development, hooks are functions that can be applied to an action or a Filter in WordPress. Actions are functions performed when a certain event occurs in WordPress. Filters allow you to modify certain functions. Arguments used to hook both filters and actions look the same. terminology (#50531) to ability to mark plugins as unmanaged (#32101) and avoid overwriting plugin files caused by update conflicts.
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/.
REST API changes are mainly focused on Widgets and sidebars but there is also a new operator for taxonomyTaxonomyA taxonomy is a way to group things together. In WordPress, some common taxonomies are category, link, tag, or post format. https://codex.wordpress.org/Taxonomies#Default_Taxonomies. queries within post collections, support for the eagerly awaited AND comparison, which allows posts meeting all passed criteria are matched (#41287).
Amongst the UI fixes, Site Health changes bring new actions for extending the navigation in the Site Health screen (#47225). You will also find new info provided by Site Health via a list of the supported file types for the active image editor (#53022).
Across the Themes changes you will find two new action hooks, delete_theme and deleted_theme (#16401), a few UI improvements such as clearly showing if a theme is a child themeChild themeA Child Theme is a customized theme based upon a Parent Theme. It’s considered best practice to create a child theme if you want to modify the CSS of your theme. https://developer.wordpress.org/themes/advanced-topics/child-themes/.

There are even more goodies in 5.8! Read through the dev notes below to see details on how Internet Explorer 11 support is being dropped as well as assorted changes to the Bootstrap/Load, Build/Test Tools, Formatting, General, Media, Posts/Post Types, RevisionsRevisionsThe WordPress revisions system stores a record of each saved draft or published update. The revision system allows you to see what changes were made in each revision by dragging a slider (or using the Next/Previous buttons). The display indicates what has changed in each revision., Themes, and Users components.
Alongside the dev notes below, also worth noting is that work has continued during the 5.8 release cycle to increase the compatibility with PHP8 and its new features. Please continue to test your code against PHP8 as we all work towards raising the entire WordPress ecosystem compatibility with PHP8, thank you!
