Disable Automatic Updates is a WordPress plugin by oneTarek that disables the automatic updates feature on a WordPress site running 3.7 or above.
Since 3.7, a typical WordPress install will now be able to automatically update itself when there is a new minor/security release available without any user input. For example, it will automatically update itself from WordPress 3.7 to 3.7.1. Auto updates are not enabled by default for major releases like 3.7.1 to 3.8. For various reasons, site owners may wish to disable this functionality.
