Hide Updates from All Non-Administrator Roles

This should not be used to avoid updating WordPress!!! I use it, along with infiniteWP.com, to make the core update process seamless for me and invisible for my clients. Add to functions.php file.

   global $user_login;
   get_currentuserinfo();
       if (!current_user_can('update_plugins')) { // checks to see if current user can update plugins 
           add_action( 'init', create_function( '$a', "remove_action( 'init', 'wp_version_check' );" ), 2 );
           add_filter( 'pre_option_update_core', create_function( '$a', "return null;" ) );
       }

global $user_login;

get_currentuserinfo();

if (!current_user_can('update_plugins')) { // checks to see if current user can update plugins

add_action( 'init', create_function( '$a', "remove_action( 'init', 'wp_version_check' );" ), 2 );

add_filter( 'pre_option_update_core', create_function( '$a', "return null;" ) );

}
