WordPress automatically updates itself for minor releases. Do you not want WordPress to automatically update itself? Here’s the code snippet:
add_filter( 'auto_update_core', '__return_false' );
or you want to disable auto-updates for Themes & Plugins?
add_filter( 'auto_update_plugin', '__return_false' );
add_filter( 'auto_update_theme', '__return_false' );
or just disable auto-update emails?
I hope this helps!
