You know, WP 3.7 introduces "automatic silent update" function. That means, WP will silently install all available updates in background without your interaction. Do you think that it's good for security of your site? (But I'm afraid of Automatic update might be too risky. It's worth discussing that "Automatic update" has already installed WP 3.7.1 silently on my blog.)
Simply add this line of code in your wp-config.php file: define( 'WP_AUTO_UPDATE_CORE', false ); PHP: Source: http://www.wpbeginner.com/wp-tutorials/how-to-disable-automatic-updates-in-wordpress/
If you are a person that does not know web and just want to interact with the users on the net than this can be a good option. For internet geek this may seem to be less comfortable.
Being that the updates are for bugs and security fixes, I would imagine that it will only help to make the website more secure and stable. I like the idea of not needing to update 50 websites .
