The new version WordPress 4.4 was named “Clifford”, in honour of jazz musician Clifford Brown. The main new features: a new default theme and responsive images. A word of explanation...

WordPress 4.4WordPress needs no introduction – this Content Management System is indeed the engine behind 25% of the Internet. A new version of this CMS is now available, and it was named “Clifford” in honour of jazz trumpeter Clifford Brown. But what are its main new features?


First of all, there is a new default theme. After Twenty Fifteen, the name of the theme available in WordPress 4.1, which was released a year ago, you can now use Twenty Sixteen. It may not be everyone’s cup of tea, which is why many WordPress webmasters will probably tweak the design in the next few days and weeks. But the most important feature that comes with our sweet sixteen is that images are fully responsive, now that srcset and sizes are also supported. Images will thus adapt to any screen, small or large, no matter if you use a smartphone, an iPad or a desktop computer. Headers are flexible, colour schemes are nice to look at, etc.


So far, you could embed content from other sites, which WordPress sees as “trusted sources” (like YouTube for instance), in your posting just by pasting the URL in your editor. In version 4.4, WordPress is now also a trusted oEmbed source itself, which means you can embed content from other WordPress sites in your own WordPress site. This content is displayed in a special iframe, with a link to comments, an icon to share the content, and a short intro about the posting.

REST under the hood

But there is more: major enhancements are under the hood and may therefore not be immediately apparent. The taxonomy system has been updated, which means you can mark the different posting categories even more clearly, with separate colours, for instance.

On a technical level, it should be pointed out that the infrastructure for the REST API has now been integrated in the core – the first part of a multi-stage rollout. Inclusion of core endpoints is targeted for an upcoming release.

For further information about this, you can read the explanation about WordPress’s REST API plug-in. And further information on WordPress 4.4 itself can be found from WordPress and from the colleagues at WPTavern.

And since a picture is worth a thousand words, this video should give you a good overview of the main new features of WordPress 4.4.
