WordPress Announces the automatic updates from version 3.7 on-wards, and this is for better security.
In WordPress, there are four types of automatic background updates:
- Core updates
- Plugin updates
- Theme updates
- Translation file updates
Configuration via wp-config.php
Using wp-config.php, automatic updates can be disabled completely, and core updates can be disabled or configured based on update type.
To completely disable all types of automatic updates, core or otherwise, add the following to your wp-config.php file:
define( 'AUTOMATIC_UPDATER_DISABLED', true );
To enable automatic updates for major releases or development purposes, the place to start is with the WP_AUTO_UPDATE_CORE constant. Defining this constant one of three ways allows you to blanket-enable, or blanket-disable several types of core updates at once.
define( 'WP_AUTO_UPDATE_CORE', false );
Hope this help….!
