What's great about WordPress 4.7 ?
New default theme called Twenty Seventeen
The theme is addressed for business sites rather than blog but it can be also used as a blog theme. It comes with the starter content (for new sites only) to give you some help for first steps with your site. The next default WordPress theme is full of awesome features starting from nice animations to adjustments to mobile devices.
Support for video headers applies to the default theme that allows setting video headers using mp4 format or YouTube movies. Now you may set video backgroud in the header area.
One flow theme set up
The new appearance of of the theme customizer improved with the direct setup.
Live previews for custom CSS
The possibility to add a custom CSS to your theme via theme customizer. The important issue is that the custom CSS applies to the previewing theme.
User admin languages option will be swichable at user profile to let you choose the language you prefer to use. The switcher appears if there is more than one language installed in WordPress.
PDF format icon previews
