Woocommerce >3.0

It isn’t official answer. I’m working for a client which has installed this plugin. Basically, it works with Woocommerce 3.0.x. You could try. I see some PHP notices which plugin author should fix:

PHP Notice: id est appelée de la mauvaise manière. Order properties should not be accessed directly. Backtrace: require('wp-blog-header.php'), require_once('wp-includes/template-loader.php'), ..., WP_Hook->do_action, WP_Hook->apply_filters, call_user_func_array, envoimoinscher->add_tracking_in_FO, WC_Abstract_Legacy_Order->__get, wc_doi in ...../wp-includes/functions.php on line 4138

PHP Notice: product_type est appelée de la mauvaise manière. Les propriétés du produit ne doivent pas être accessible directement.

PHP Notice: WC_Shipping_Zone::get_zone_id est <strong>déprécié</strong> depuis la version 3.0 ! Utilisez WC_Shipping_Zone::get_id à la place. in .....wp-includes/functions.php on line 3830

Possible fixes:

$order->id could be replaced with:
$order_id = version_compare( WC_VERSION, '3.0.0', '<' ) ? $order->id : $order->get_id();

$item['data']->price could be replaced with:
$item_price = version_compare( WC_VERSION, '3.0.0', '<' ) ? $item['data']->price : $item['data']->get_price();

Fixes for product_type:

if ( 'variable' === ( version_compare( WC_VERSION, '3.0.0', '<' ) ? $product->product_type : $product->get_type() ) ) {

if ( 'simple' === ( version_compare( WC_VERSION, '3.0.0', '<' ) ? $product->product_type : $product->get_type() ) ) {

Fixes for zone_id:
$default_zone_id = version_compare( WC_VERSION, '3.0.0', '<' ) ? $default_zone->get_zone_id() : $default_zone->get_id();

I found new deprecated methods shipping_postcode, shipping_city and shipping_country. Possible fixes:

$order_shipping_postcode = version_compare( WC_VERSION, '3.0.0', '<' ) ? $order->shipping_postcode : $order->get_shipping_postcode(); 
$order_shipping_city     = version_compare( WC_VERSION, '3.0.0', '<' ) ? $order->shipping_city : $order->get_shipping_city();
$order_shipping_country  = version_compare( WC_VERSION, '3.0.0', '<' ) ? $order->shipping_country : $order->get_shipping_country();

Also, there are issue related to dashboard javascripts. I already reported it: https://wordpress.org/support/topic/javascript-dependencies-for-woo-scripts/
