Add Shortcode Deprecated Error

After doing some WP updates, I logged out and then this error came up.

Notice: wpcf7_add_shortcode is deprecated since Contact Form 7 version 4.6! Use wpcf7_add_form_tag instead. in /home/whartever/public_html/kindspaevents.com/wp-content/plugins/contact-form-7/includes/functions.php on line 355

Which I guess relates to this:

function wpcf7_deprecated_function( $function, $version, $replacement ) {
	$trigger_error = apply_filters( 'deprecated_function_trigger_error', true );

	if ( WP_DEBUG && $trigger_error ) {
		if ( function_exists( '__' ) ) {
			trigger_error( sprintf( __( '%1$s is <strong>deprecated</strong> since Contact Form 7 version %2$s! Use %3$s instead.', 'contact-form-7' ), $function, $version, $replacement ) );
		} else {
			trigger_error( sprintf( '%1$s is <strong>deprecated</strong> since Contact Form 7 version %2$s! Use %3$s instead.', $function, $version, $replacement ) );
		}
	}
}

That’s very unusual. Any idea why I would receive this?
