Version 4.7 of WordPress, named “Vaughan” in honor of legendary jazz vocalist Sarah “Sassy” Vaughan, is available for download or update in your WordPress dashboard. New features in 4.7 help you get your site set up the way you want it.
Presenting Twenty Seventeen
A brand new default theme brings your site to life with immersive featured images and video headers.
Twenty Seventeen focuses on business sites and features a customizable front page with multiple sections. Personalize it with widgets, navigation, social menus, a logo, custom colors, and more. Our default theme for 2017 works great in many languages, on any device, and for a wide range of users.
Your Site, Your Way
WordPress 4.7 adds new features to the customizer to help take you through the initial setup of a theme, with non-destructive live previews of all your changes in one uninterrupted workflow.
To help give you a solid base to build from, individual themes can provide starter content that appears when you go to customize your brand new site. This can range from placing a business information widget in the best location to providing a sample menu with social icon links to a static front page complete with beautiful images. Don’t worry – nothing new will appear on the live site until you’re ready to save and publish your initial theme setup.
