Hi Mahdi,
See below for updating to WooCommerce 4.9.0.
There is a new version of WooCommerce available. View version 4.9.0 details or update now.
Heads up! The versions of the following plugins you're running haven't been tested with WooCommerce 4.0. Please update them or confirm compatibility before updating WooCommerce, or you may experience issues:
Plugin - Tested up to WooCommerce version
Hypermarket Plus - 3.7.0
Is it safe to update to WooCommerce 4.9.0 & Wordpress 5.6? Let me know.
Are there any updates available soon?
Thanks
