Software is always evolving. Each day, developers are hard at work improving WooCommerce. When they created a better version of the software, they release an update. If you want your site to be the best it can be, you need to get used to upgrading WooCommerce to WooCommerce with the higher version.
An update is a bit like medicine. It’s good for you, but sometimes there are interesting side effects. So, to make sure your site continues running as it should, we suggest testing the update.
