So, for an extension like Shipstation, which is how many ecommerce sites manage postage and labeling, I see that they haven't updated their extension since last year: https://woocommerce.com/products/shipstation-integration/ https://woocommerce.com/products/shipstation-integration/. The listed compatibility is with WooCommerce 3.3. Put yourself in the shoes of an ecommerce site operator. When a Wordpress minor release like 4.9 comes out, do I upgrade or not? How do I balance the security patches with the potential of breaking a critical part of my workflow? EDIT: I meant WC 3.3. 4.1.19 was actually the plugin version
