WordPress 4.7.5 became available today. The new version addresses 6 security issues affecting WordPress 4.7.4 and earlier releases. It also includes 3 maintenance fixes to the 4.7 release series.
While WordPress.org already started automatic background updates that do not require you to do anything it may take some time for them to get to your website. If it does not update automatically today, do it yourself (if you are confident enough) or contact Dusk Owl for help.
