We have just released WooCommerce Multilingual 2.3. It is another bugfix release and everybody using variations should consider updating.
In this release we continue to cover more areas in attribute synchronization. We now take care of copying also the order of (both global and custom) product attributes and categories, and we translate attributes even if they arent used in variations. Variation ordering is also taken care of properly.
The cart widget is properly refreshed when currency is switched, both filter navigation widgets are now working and a few other minor bugs have been fixed.
If you find any problems, please report them to our support forum and we will take care of them. Make sure to check first our greatly improved documentation; it has undergone a major upgrade with this release.
