Version 4.7 of WordPress, named Vaughan in honor of legendary jazz vocalist Sarah Sassy Vaughan, is available.

CUSTOM CSS

Sometimes you just need a few visual tweaks to make your site perfect. WordPress 4.7 allows you to add custom CSS and instantly see how your changes affect your site. The live preview allows you to work quickly without page refreshes slowing you down.

PDF THUMBNAIL PREVIEWS

Managing your document collection is easier with WordPress 4.7. Uploading PDFs will generate thumbnail images so you can more easily distinguish between all your documents.

USERS SELECT THEIR PREFERRED LANGUAGE FOR DASHBOARD

Just because your site is in one language doesn’t mean that everybody helping manage it prefers that language for their admin. Add more languages to your site and a user language option will show up in your user’s profiles.

INTRODUCING REST API CONTENT ENDPOINTS

WordPress 4.7 comes with REST API endpoints for posts, comments, terms, users, meta, and settings.

Content endpoints provide machine-readable external access to your WordPress site with a clear, standards-driven interface, paving the way for new and innovative methods of interacting with sites through plugins, themes, apps, and beyond.
