Key Features to Test 🔑


Global Styles RevisionsRevisions The 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.

This release introduced a handy feature that allows you to reset global styles back to their default settings with ease (52965). With this enhancement, you can effortlessly reset any changes made to global styles back to their original state. To try out this feature, simply make a few revisions to the global style and then open the revision panel. You’ll see a list of all the revisions, and at the bottom, there’s an option called “Reset to Default.” Click on it to return to the original settings.  Now, you only need to go through one revision check instead of two (53281). Previously, the revision panel was only available after two styles of revisions were saved in the database.

Block HooksHooks In 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. (Previously Auto-inserting Blocks)

Introducing the Block Hooks feature, a reimagined approach to the earlier concept of Auto-inserting Blocks. Basically, Block Hooks is an APIAPI An 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. that developers can use to make websites more flexible. It allows one block to attach itself to another block and show its content before or after that block. You can also attach a block to a parent block and make it appear at the beginning or end of the list of child blocks inside it. (53987

Even though Block Hooks is mainly for developers, it also gives a nice experience to the end users by automatically inserting a block into a specific location. It lets developers place blocks where they want them to be and gives room for customization. The goal is to make block themes more adaptable with the help of plugins.

One thing to keep in mind is that the block using this API will only be auto-inserted if the original template or part hasn’t been changed by the user. This is done to respect the user’s choice. This API can only be applied with block patterns, template parts, and templates that come from the block theme files. It doesn’t alter anything the user has already created or changed on a website. 

Note: This feature is a more technical item to test. Check out this for a more detailed guide.

Query LoopLoop The Loop is PHP code used by WordPress to display posts. Using The Loop, WordPress processes each post to be displayed on the current page, and formats it according to how it matches specified criteria within The Loop tags. Any HTML or PHP code in the Loop will be processed on each post. Block Pagination Enhancements 

Now, you no longer need a full page reload when you navigate between pages in a Query Loop block. There’s a new setting that prevents full page reloads. This improved way of moving between pages is made possible by a special version of the Interactivity API, and it makes browsing smoother. Plus, you can also decide how many pages you want to show using the Query Page Numbers block for even more control.

Add Lightbox Functionality for your Images

Within this panel, users can easily locate the Lightbox toggle, available both in Global Styles and Block settings.Display your pictures in an engaging way using the brand-new lightbox functionality.

Create your own Pattern Categories

Now, you can neatly group your patterns by categories when you create them. These categories are handy because you can use them to organize and find your patterns easily. You can also edit these categories in the 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. when you’re editing a pattern.

To ensure this feature functions smoothly, here are the steps to follow: Begin by adding various user patterns, both synced and unsynced, assigning categories to each (remember to hit ‘enter’ or add a ‘,’ after each categoryCategory The 'category' taxonomy lets you group posts / content together that share a common bond. Categories are pre-defined and broad ranging.). Then, navigate to the site editor patterns page and verify that the categories appear in the left navigation panel. Confirm that selecting a category displays the corresponding patterns accurately and that theme patterns continue to appear as expected. Check that all patterns are accessible under ‘All Patterns’ and that the search function operates seamlessly. Lastly, duplicate a theme pattern and ensure that the new pattern inherits the same category. Additionally, when adding a user pattern with the ‘Footer’ category, make sure it displays alongside the theme Footer patterns, taking into account the category slug distinction (theme patterns use ‘footer’ while the user category name should match this).
To make things even simpler, all patterns, whether they’re synced or not, are listed together in one place. There’s no need to look in different tabs for synced patterns; they’re all in the same section. (53837)

Import/Export Patterns as 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. files.

To maintain compatibility with Reusable blocks, you can now import and export patterns as JSON files, providing a straightforward way to transfer custom patterns between websites. (54337
