Here are some highlights from the newest WordPress release:
Don’t lose your place: stay on the same page while you update, install, and delete your plugins and themes.
The WordPress dashboard now takes advantage of the fonts you already have, making it load faster and letting you feel more at home on whatever device you use.
Inline Link Checker
Ever accidentally made a link to https://wordpress.org/example.org? Now WordPress automatically checks to make sure you didn’t.
As you type, WordPress saves your content to the browser. Recovering saved content is even easier with WordPress 4.6.
Under the Hood
Resource hints help browsers decide which resources to fetch and preprocess. WordPress 4.6 adds them automatically for your styles and scripts making your site even faster.
The HTTP API now leverages the Requests library, improving HTTP standard support and adding case-insensitive headers, parallel HTTP requests, and support for Internationalized Domain Names.
Meta Registration API
The Meta Registration API has been expanded to support types, descriptions, and REST API visibility.
Translations On Demand
WordPress will install and use the newest language packs for your plugins and themes as soon as they’re available from WordPress.org’s community of translators.
Masonry 3.3.2, imagesLoaded 3.2.0, MediaElement.js 2.22.0, TinyMCE 4.4.1, and Backbone.js 1.3.3 are bundled.
Customizer APIs for Setting Validation and Notifications
Settings now have an API for enforcing validation constraints. Likewise, customizer controls now support notifications, which are used to display validation errors instead of failing silently.
Multisite, now faster than ever
Cached and comprehensive site queries improve your network admin experience. The addition of
WP_Network_Query help craft advanced queries with less effort.
