For example, 3.7.2 install is served a 3.7.3 update, but the current version is 3.8.1. This commit also allows for core update notification emails to be sent even when we are unable to run an auto update due to filesystem configuration (VCS checkout or file permissions). But, since these emails go through WP_Automatic_Updater, they will not be sent if the updater is outright disabled. fixes #25654. Built from https://develop.svn.wordpress.org/trunk@25873 git-svn-id: http://core.svn.wordpress.org/trunk@25785 1a063a9b-81f0-0310-95a4-ce76da25c4cd
