The WooCommerce 2.1.6 release is now available via WordPress.org or automatic update in your administration panel. This fix release is the result of the continued effort of our contributors who contribute code and others who have reported issues with the plugin. Thank you for helping out!
All the changes are relatively small and can be found in the changelog. A total of 91 commits made it into this release, bundling them into one larger release makes it a decent fix release.
