WooCommerce Order Status Manager - V1.15.4
Version: 1.15.4
* Fix - Replace deprecated `is_ajax()` function calls with `wp_doing_ajax()`
* Misc - Require WooCommerce 3.9.4 or newer
Fix - Improve compatibility with WooCommerce Subscriptions, so orders that transition from 'on-hold' to a paid order status have the associated subscription activated
