WordPress 5.6

What's new in this version:

Greater layout flexibility:
- Bring your stories to life with more tools that let you edit your layout with or without code. Single column blocks, designs using mixed widths and columns, full-width headers, and gradients in your cover block—make small changes or big statements with equal ease!

More block patterns:
- In some themes, preconfigured block patterns make setting up standard pages on your site a breeze. Let the power of patterns streamline your workflow and save you clicks. Plus, share these features with clients, editors, and more.

Better video captioning:
- To help you add subtitles or captions to your videos, you can now upload them within your post or page. This makes it easier than ever to make your videos accessible for anyone who needs or prefers to use subtitles.

Twenty Twenty-One is here:
- Twenty Twenty-One is a blank canvas for your ideas, and the block editor is the best brush. It is built for the block editor and packed with brand-new block patterns you can only get in the default themes. Try different layouts in a matter of seconds, and let the theme’s eye-catching, yet timeless design make your work shine.
- What’s more, this default theme puts accessibility at the heart of your website. It conforms to the WordPress accessibility-ready guidelines and addresses several more specialized standards from the Web Content Accessibility Guidelines (WCAG) 2.1 at level AAA. It will help you meet the highest level of international accessibility standards when you create accessible content and choose plugins which are accessible too!

A rainbow of soft pastels:
- Perfect for a new year, Twenty Twenty-One gives you a range of pre-selected color palettes in pastel, all of which conform to AAA standards for contrast. You can also choose your own background color for the theme, and the theme chooses accessibility-conscious text colors for you — automatically!
- Need more flexibility than that? You can also choose your own color palette from the color picker

Improvements for everyone:
Expanding auto-updates:
- For years, only developers have been able to update WordPress automatically. But now you have that option, right in your dashboard. If this is your first site, you have auto-updates ready to go, right now! Upgrading an existing site? No problem! Everything is the same as it was before.

Accessibility Statement:
- Even if you’re not an expert, you can start letting others know about your site’s commitment to accessibility! The new feature plugin includes template copy for you to edit and publish, and it’s written to support different contexts and jurisdictions.

Built-in Patterns:
- If you’ve not had the chance to play with block patterns yet, all default themes now feature a range of block patterns that let you master complex layouts with minimal effort. Customize the patterns to your liking with the copy, images, and colors that fit your story or brand.

For developers:
REST API authentication with Application Passwords:
- Thanks to the API’s new Application Passwords authorization feature, third-party apps can connect to your site seamlessly and securely. This new REST API feature lets you see what apps are connecting to your site and control what they do.

More PHP 8 support:
- 5.6 marks the first steps toward WordPress Core support for PHP 8. Now is a great time to start planning how your WordPress products, services, and sites can support the latest PHP version. For more information about what to expect next, read the PHP 8 developer note.

jQuery:
- Updates to jQuery in WordPress take place across three releases 5.5, 5.6, and 5.7. As we reach the mid-point of this process, run the update test plugin to check your sites for errors ahead of time
- If you find issues with the way your site looks ( e.g. a slider doesn’t work, a button is stuck — that sort of thing), install the jQuery Migrate plugin
