We have just released WPML Multilingual & Multicurrency for WooCommerce 2.1. It is a bugfix release and everybody using variations should consider updating.
We still maintain backwards compatibility with WooCommerce 1.6 while fixing bugs to have a smoother experience with WooCommerce 2.0.

This release includes fixes for variation synchronization, specifically for the case when there are more than 2 languages. Also the method to pick the translated attribute values has changed and is more robust. We fixed rounding issues in currency conversion and added support for a couple of new pages in WooCommerce 2.0 (lost password and review order).
As usual, if you find any problems, please report them to our support forum and we will take care of them.
