WordPress 4.5 Beta 2 发布了，该版本改进内容包括： Added Horizontal Rule (HR) editing shortcut and dismissible “Paste as Text” notice in TinyMCE. Selective Refresh support is enabled for core themes titles and taglines, which allows shift-click to focus on controls and PHP filters to apply in the preview. Resolved a fatal error on image upload when ImageMagick could not complete stripping meta during resize (#33642). Various bug fixes. We’ve made just over 100 changes in the last week. 下载地址：https://wordpress.org/wordpress-4.5-beta2.zip WordPress 4.5 Beta 2 发布下载地址
