Similar to the image widget, WordPress 4.8 also includes a video widget. It allows you to easily upload videos to the WordPress sidebar or display any video from YouTube, Vimeo, or any other 嵌入 provider.
Previously, the default text widget was just a plain text area where you needed to add your own HTML even for very basic formatting. WordPress 4.8 ships with the new and improved text widget with 可视化编辑器 support.
It is the light version of the same visual editor that you use to write posts and pages. It contains buttons to make text bold or italic, add lists, and links. Advanced users can still switch to the 文本编辑器 to write HTML manually.
WordPress新闻和事件仪表板小部件 （WordPress News and Events Dashboard Widget）
WordPress 4.8 also introduced the new ‘WordPress News and Events’ dashboard widget. It appears on the dashboard screen of your WordPress 管理区 and displays WordPress news as well as WordPress events near your location.
If you have multiple users on your site, then each user will see events near their own location. The widget automatically tries to guess user’s location by sending their IP address, timezone, and locale to api.wordpress.org. If you are using a VPN服务, then you will see the events based on the sever location you are using.
If you have used live theme customizer on large screens, then you may have noticed that the sidebar looks too narrow. WordPress 4.8 makes the customizer sidebar width to be proportional to users screen size. (#32296)
