An automatic update feature was added with the release of WordPress 3.7. An out of the box WordPress install will now update itself whenever there is a minor security release available without any user input (for example, WordPress 3.8.1 will auto update to 3.8.2). The automatic update feature does not download and install major releases, such as 3.7 to 3.8, but allowing WordPress to automatically install minor updates and security patches may still be a concern. Several of my customers have asked how to disable these automatic updates in WordPress.
WordPress decided not to include an easy on/off button for disabling automatic updates, but this can be accomplished with a very simple line of code.
To disable WordPress automatic updates, edit your wp-config.php file and add the following line of code:
define( 'WP_AUTO_UPDATE_CORE', false );
Save your changes to disable automatic updates. You will still receive a notification in your WordPress admin panel when a new version is available, allowing you to control when updates are installed.
I hope you have found this information helpful. What are your thoughts? Do you want WordPress to automatically install updates, or will you disable them?
