Fix for scheduled published posts

Hi, great plugin. I was looking for a bit of functionality surrounding scheduled posts being published. I changed the “publish_status” hook, which is deprecated in email-subscribers.php to “transition_post_status”. This hook provides additional parameters to es_prepare_notification() regarding pre/post status, which allows for the removal of $_POST status variables. I placed my solution below in case you’re interested. Cheers Marty

PS never used SVN, just GIT, otherwise I’d have made a pull request after making the changes myself

./email-subscribers.php:line 48

/**

// Original deprecated hook
//add_action( 'publish_post', array( 'es_cls_sendmail', 'es_prepare_notification' ) ); 

// New hook which returns status and post id
add_action( 'transition_post_status', array( 'es_cls_sendmail', 'es_prepare_notification' ), 10, 3 );

./classes/es-sendmail.php:line 29

/***

public static function es_prepare_notification( $post_status, $original_post_status, $post_id )
{
    /***

     */
     //$post_status = isset($_POST['post_status']) ? $_POST['post_status'] : '';
     //$original_post_status = isset($_POST['original_post_status']) ? $_POST['original_post_status'] : '';

     ... // Rest of original function
}
