WooCommerce 3.2 is coming, and is scheduled for October 12th. This release is intended to be backwards-compatible. However, it is always recommended to test upgrades on a development version of your site, before trying on the live site.
We have been testing our range of WooCommerce extensions, and not found any compatibility issues with current versions. A minor update was issued for Opening Hours/Delivery Times, because WooCommerce 3.2 messes up the layout of the settings (but without affecting functionality).
