On August 19, WooCommerce released version 6.8.1 which introduces a fix for a shipping issue that was introduced in the 6.8.0 release. On August 23, WooCommerce released version 6.8.2, because some version numbers were incorrectly updated in 6.8.1, causing problems for some sites. These version numbers were correctly updated in this version of WooCommerce. No other changes were made, so if your 6.8.1 install is working feel free to skip the update.
The WooCommerce team is updating automation to prevent this sort of error from reoccurring. You can download the latest release of WooCommerce here or visit Dashboard → Updates to update the plugin from your WordPress admin screen.
As always, you might want to do the update in a test environment first and backup your production site before updating.
