Version 4.4 of WordPress, named “Clifford” in honour of jazz trumpeter Clifford Brown, is available for download or update in your WordPress dashboard. New features in 4.4 make your site more connected and responsive. Clifford also introduces a new default theme, Twenty Sixteen.
Introducing Twenty Sixteen
Our newest default theme, Twenty Sixteen, is a modern take on a classic blog design.
Twenty Sixteen was built to look great on any device. A fluid grid design, flexible header, fun colour schemes, and more, will all make your content shine.
Responsive Images
WordPress now takes a smarter approach to displaying appropriate image sizes on any device, ensuring a perfect fit every time. You don’t need to do anything to your theme, it just works.
Embed Everything
Now you can embed your posts on other WordPress sites. Simply drop a post URL into the editor and see an instant embed preview, complete with the title, excerpt, and featured image if you’ve set one. We’ll even include your site icon and links for comments and sharing.
In addition to post embeds, WordPress 4.4 also adds support for five new oEmbed providers: Cloudup, Reddit Comments, ReverbNation, Speaker Deck, and VideoPress.
Under the Hood
REST API infrastructure
Infrastructure for the REST API has been integrated into core, marking a new era in developing with WordPress. The REST API gives developers an easy way to build and extend RESTful APIs on top of WordPress.
Infrastructure is the first part of a multi-stage rollout for the REST API. Inclusion of core endpoints is targeted for an upcoming release. To get a sneak peek of the core endpoints, and for more information on extending the REST API, check out the official WordPress REST API plugin.
Term meta
Terms now support metadata, just like posts. See add_term_meta(), get_term_meta(), and update_term_meta() for more information.
Comment query improvements
Comment queries now have cache handling to improve performance. New arguments in WP_Comment_Query make crafting robust comment queries simpler.
Term, comment, and network objects
New WP_Term, WP_Comment, and WP_Network objects make interacting with terms, comments, and networks more predictable and intuitive in code.
