Deprecated Calls

Using wp-content/plugins/subscribe-to-double-opt-in-comments/subscribe-to-doi-comments.php and the functions wpdb::escape() and get_settings() Deprecated Calls are used.

1.Use wpdb::prepare() or esc_sql() instead.
Deprecated in version 3.6.

2. Use get_option() instead.
Deprecated in version 2.1.

Would it be possible to Change this with the next update?
