WordPress 5.7 Beta 1

WordPress 5.7 Beta 1 is now available for testing!

This software is still in development, so it’s not recommended to run this version on a production site. Consider setting up a test site to play with the new version.

You can test the WordPress 5.7 Beta 1 in two ways:

• Install/activate the WordPress Beta Tester plugin (select the Bleeding edge channel and the Beta/RC Only stream)
• Direct download the beta version here (zip).

The current target for final release is March 9, 2021. That’s just five weeks away, so your help is vital to making sure that the final release is as good as it can be.

So what’s new?

Improvements in Core

Lazy-load iframes
Now you can enable lazy-loading of iframes by adding the loading="lazy" attribute to iframe tags on the front-end. 

Migrating from HTTP to HTTPS is streamlined
Switching a WordPress site from HTTP to HTTPS has proven to be a pain for all involved. While on the surface, the Site Address and WordPress Address have to be updated, content with embedded HTTP URLs remains unchanged in the database. With this release, migrating a site to HTTPS is now a one-click interaction. URLs in the database are automatically replaced when the Site and WordPress Address are both using HTTPS.  Also, Site Health now includes an HTTPS status check.

Standardize colors used in WP-Admin CSS to a single palette
This change collapses all colors used in the CSS to one of the available shades of blue, green, red, yellow, grey, black, and white. The palette makes it simpler than ever to build components your users can read, because half the range gives you great contrast with white type and a half with black, according to current accessibility guidelines.

Ongoing cleanup after update to jQuery 3.5.1
jQuery deprecations in WordPress Core and bundled themes show up a lot less often, and the notifications make more sense to the user.

New Robots API
The new Robots API allows the filter directives to be included in the ‘robots’ meta tag. Also, the directive max-image-preview:large is now included by default to allow large image previews to be displayed in search engines (unless the blog is marked as not being public).
