New Default Theme – Twenty Sixteen
- Modern take on the classic blog design
- Flexible header and fun color schemes will make your content shine
- Mobile-first and responsive
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 your WordPress content:
Now you can embed your posts on other sites, even 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.
Even more embed providers:
In addition to post embeds, WordPress 4.4 also adds support for five new oEmbed providers: Cloudup, Reddit Comments, ReverbNation, Speaker Deck, and VideoPress.
REST API infrastructure: Infrastructure for the REST API has been integrated into core, the first part of a multi-stage rollout. 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.
- Developer reference – Improvements to inline code documentation.
- i18n support – Improvements to translation strings all over the core.
- Admin page headings were adjusted from H3 to H2 tags to reinforce page hierarchy
- Improvements to how list tables are displayed on all size screens
The post/page permalink UI was simplified, linking the permalink and removing the “View” button
- The “View Comment” link was relocated from the Status meta box in the comment-editing screen
- Many comment functions can now accept a full object instead of ‘comment_ID’ to reduce cache/db lookups
- Orphaned comments now fall back to the ‘edit_posts’ capability
Site icons will now fall back to the ‘full’ size URL when the ‘thumbnail’ size doesn’t exist
