WordPress 5.0.1 is now available. This is a security release for all versions since WordPress 3.7. It is strongly recommended that you to update your websites immediately.
WordPress versions 5.0 and earlier are affected by several bugs, which are fixed in version 5.0.1. Updated versions of WordPress 4.9 and older releases are also available, for users who have not yet updated to 5.0.
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.
