Activate revisions for Woocommerce products

By default, Woocommerce products don’t support revisions as other post types do. If you need they do it, add this to your functions.php:

add_filter( 'woocommerce_register_post_type_product', function( $args ) {
    $args['supports'][] = 'revisions';
    return $args;
} );

add_filter( 'woocommerce_register_post_type_product', function( $args ) {
    $args['supports'][] = 'revisions';
    return $args;
} );

Now you can track changes of every single product.
