WordPress 5: last year's major release and what it gave to us
A year ago, WordPress 5.0 release came out, bringing new features, including:
- a new default JavaScript-based content editor Gutenberg with unique opportunities for non-tech users to create rich posts and pages with a drag-and-drop interface
- a new pre-installed theme — Twenty Nineteen
- a new built-in lightweight front-end editor that inherits its features from the Customizer framework
- a background image cropping feature
- security improvements
What’s new in WordPress 5.3: a closer look at the new release
The highlight of what’s new in WordPress 5.3 is that we should see much more convenient user interfaces and more intuitive interaction between the user and the site.

New default theme — Twenty Twenty
WordPress websites will get a new elegant default theme. The Twenty Twenty theme has been developed by Anders Noren on the basis of an earlier WP theme — Chaplin.
The new theme fully supports the WordPress block editor Gutenberg, allowing users to create beautiful layouts for posts and pages. It also provides a full-width template for them.

The Twenty Twenty theme has a focus on readability, so it includes the Inter typeface. This allows you to create crisp and prominent headlines and displays beautifully on devices of all sizes.

Improvements to Gutenberg blocks
The Gutenberg editor’s arrival in the WP 5.0 release created a big splash both among developers and users. If you want more information, we shared an article on how to use the Gutenberg editor in WordPress. Gutenberg treats layout elements as blocks.
So, anyone who asks what’s new in WordPress 5.3, should hear about numerous improvements to Gutenberg blocks:
- width adjustment and patterns in the “Columns”
- reordering and caption options in the “Gallery”
- style selection options in the “Image”
- alignment, color, header/footer options in the “Table”
- border radius and target support for the “Button”
- the option to add excerpts to the “Latest posts”
- better block grouping
- new configurable block for social links
- performance improved by 1.5 seconds compared to WP 5.2
and much more.
Image uploading improvements
WordPress is now able to resume the uploading of large, high-resolution images if it failed due to connection problems. Another new useful feature is that images also undergo the correct rotation according to the EXIF orientation.
More convenient and accessible admin dashboard
The WordPress admin dashboard will have better color contrasts on buttons and forms, an improved color palette, and better zoom management. This will raise its usability and accessibility for all users.
Changes to the “Website health” check
The website health check is a useful feature introduced in WP 5.1 that helps admins keep an eye on the site’s performance.
In the WP 5.3 release, website health will no longer be displayed in a percentage. Instead, it is presented in the form of scores like “Should be improved” and “Good.”
Admin email address checking
Site admins are now protected against the risk of being locked out of the site in case of email address changes. WordPress will regularly check if their admin email address is relevant and up-to-date.
PHP 7.4 support
The next block of what’s new in WordPress 5.3 will primarily interest developers — the new WP version will support the forthcoming PHP 7.4.
WordPress gets rid of the deprecated code to ensure compatibility with the freshest and most efficient programming language release.
