This version promises to build upon the platform’s reputation for user-friendliness, versatility, and performance. Ultimately, it’ll solidify its position as the go-to choice for creating and managing dynamic websites.

Unquestionably, WordPress will bring various improvements, optimizations, and features to enhance the user experience. Exactly, you’ll get over 500 new features and enhancements, plus 400+ bug fixes, in this release.

Hence, this update will cater to both beginners and seasoned developers, allowing them to unleash their creativity.

As the general release date approaches, anticipation builds within the WordPress community. So, you may be eagerly awaiting to explore the new version’s potential. Isn’t it?

New Highlights of WordPress 6.3

Currently, you’ll find various beta versions and the first Release Candidate. All of them are ready for download and testing. So, you can check and evaluate them on a test website. But these features may change before the final release.

We’ve already tested and monitored the new features on a test website. Best of all, we’ve compiled all the latest WordPress highlights below. 

So, what are you waiting for? Let’s find them out now!

1. Amplified Performance

The previous WordPress 6.2 version had incredible performance enhancements. Now, the new release is set to have over 170 performance-related updates. That includes:

  • Defer and async support to the WP Scripts API (Application Programming Interface).
  • Block template resolution optimization.
  • Better support for PHP versions 8.0, 8.1, and 8.2.
  • Optimizations on image lazy-loading and the emoji loader, etc.

Ending Support for PHP 5

In fact, WordPress 6.3 will end its support for PHP 5. Yes, you read it right!

WordPress 6.2 supports PHP 5.6.20 or greater. But only 3.9% of monitored installations currently use PHP 5.6 as of July 2023. 

So, the WordPress core team has discontinued support for PHP 5.6.20. While the minimum supported version is set to PHP 7, the recommended PHP version remains PHP 7.4 or greater.

Update to Recommended PHP Version
Update to Recommended PHP Version

Are you using PHP 5.6 on your website? Wondering what will happen to your website? Such sites will remain on the WordPress 6.2 branch with continuous security updates. As the security policy supports WordPress versions 4.1 and greater.

Hence, we recommend PHP 5.6 website owners change their PHP version settings from their hosting control panel.

Further, Gutenberg is a WordPress plugin to improve the block editor’s capabilities. It has a separate release plan from the WordPress core and supports the 2 most recent WordPress releases. So, Gutenberg will probably support PHP 5.6 until WordPress 6.4 is released.

2. Effortless Site Editor

This upcoming WordPress version will have a new look for the Site Editor. You’ll get a more efficient and user-friendly experience while navigating, editing, and managing your site.

So, let’s check out the key highlights one by one!

Redesigned Navigation Sidebar

If you use the 6.2 version, then you can find a new navigator for the site editor. The menus in the sidebar include ‘Templates’ and ‘Template Parts’

Now, 6.3 will expand this navigation sidebar and insert more menus. They are:

  • Navigation: Here, you’ll find the links present in your navigation block. Also, you can rearrange or remove your menu items and use the ‘Edit’ option to make changes.

  • Pages: On this menu, you’ll see all available pages on your site, including drafts. Most of all, you can open, edit, and set up the page directly from the site editor.
  • Templates: Like previously, this menu includes templates that you can choose for editing. Further, you can click the ‘Add New Template’ option to build a new one.
  • Patterns: Here reside the Template Parts along with the ‘Theme Patterns’ and ‘My Patterns’. There, it also includes options to let you manage them separately.

So, let’s see how!

When you open the site editor on any page or template, you’ll find the page or template name you’re viewing at the top. Besides that, there’s the ‘Ctrl+K’ option.

If you click on it, then the command palette opens. There, you can search for the panel you want to open or the task you want to do.

Suppose you’re editing the Blog Home template and want to quickly add a new post. Then, you can search for the term ‘add’ and you’ll already see the option ‘Add new post’. Click this option, and it’ll take you to the post editor. As simple as that!

Don’t know what distraction-free mode is? This mode hides all side and top panels and disables the block toolbar. All of that is to let you focus on editing the content.

4. Improvements to Patterns

Delightfully, you’ll get a lot of improvements to patterns in the upcoming update. So, let’s check them out!

Synced and Unsynced Patterns

First, WordPress 6.3 will combine reusable blocks and patterns for better customizability and user experience. In fact, the new version introduces 2 types of patterns:

  • Synced: Synced patterns are reusable blocks with a different name. When you change them, it’ll affect the original synced patterns.
  • Unsynced: Unsynced patterns are the traditional block patterns. You can insert them at any time and make changes without affecting the original patterns.

Easily Create, Save, and Manage Patterns

On the site editor, the ‘Patterns’ menu shows the template parts and patterns. Specifically, you can create, save, and manage both synced and unsynced patterns here. Let’s see!

First, click the ‘Create pattern’ option that gives 2 options:

  • Create template part
  • Create pattern

Now, choose the 2nd option, and you’ll get a popup. There, write the name of the new pattern. Also, you can see the ‘Keep all patterns instances in sync’ option.

If you disable that option and click the ‘Create’ button, then you’re creating an unsynced pattern. But if you enable it and hit the ‘Create’ button, then it becomes a synced pattern.

Now, you can design your pattern and click the ‘Save’ button. 

Additionally, all your patterns will get saved inside the ‘My patterns’ category. You can also find a search button to find a pattern. Further, there are 3 categories, namely All, Synced, and Standard. This helps you distinguish reusable blocks and patterns.

5. Usability Enhancements

Here’s a description of the various usability features you’ll receive with the new update. All of them focus on easing the process of creating a website. Let’s go!

Toolbar Updates

By default, a block toolbar is shown right at the top of the block when you select it. This takes up more space and may hamper your editing process.

But the improved ‘Top toolbar’ feature can now show the block toolbar of each block on a common top panel. Yes! All the block and document tools are in one place.

Confused? Let’s use this feature to understand it better.

On the editor, go to ‘Options’ on the right side and enable the ‘Top toolbar’ feature.

You’ll find the improved padding and margin controls in the Dimensions styles. With the update, you can easily set the padding and margin from all sides or from each side separately.
