By default, WordPress automatically updates when minor releases become available, but does not automatically update your site to major releases.
For example, if you are currently using WordPress 5.6.2, the next minor release would be 5.6.3, and WordPress will automatically update to that version once it's available.
However, if you are currently using WordPress 5.6.2 and version 5.7 is released, WordPress will not automatically update to 5.7; you will need to perform that update manually.
We strongly recommend leaving this default functionality in place. It ensures that you get bugfixes and security updates as soon as they are released, while avoiding major updates that your themes or plugins may not yet be ready for.
If you don't want WordPress to ever automatically update its core for any release (major or minor), you can add the following line in your wp-config.php file:
define( 'wp_auto_update_core', false );
A good place to add it is near the bottom of the file, above the line that says
/* That's all, stop editing! Happy publishing. */ Just add the code above on its own, save the file, and upload it via SFTP. Note that this file, like a plugin or theme file, requires PHP syntax, and any syntax errors will make your site nonfunctional. Please contact us if you need assistance.
