Custom cart item data not stored in last version

Hi,

since last update code does not work anymore, this is an example of my custom code :

add_filter( 'woocommerce_get_item_data',  'custom_get_item_var_data' , 10, 2 );
add_filter( 'woocommerce_add_cart_item_data',  'custom_add_to_var_cart_product' , 10, 2 );
function custom_get_item_var_data( $other_data, $cart_item_data ) {
	if ( isset( $cart_item_data['myCustomData'] ) ) {
        $other_data[] = array(
            'name' => 'My custom data',
            'value' => $cart_item_data['myCustomData']
        );
    }
	return $other_data;
}
function custom_add_to_var_cart_product( $cart_item_data, $product_id ) {
	$cart_item_data['myCustomData'] = 'someCustomValue';
	if ( empty( $cart_item_data['options'] ) ) {
		$cart_item_data['options'] = array();
	}
	return $cart_item_data;
}

MyCustomData is no longer displayed in the cart because it’s not stored in $cart_item_data variable in woocommerce_get_item_data filter

i tested it in previous version and it’s OK.

Do you know what is the problem ?
Thanks
