The Japanese and German versions of Siena are now available in the Windows Store.
Note that we have done an unusually "deep" globalization and localization. For example, it's not just the UI menus that will appear in Japanese and German. Every formula, every function, every property name will now be in the right language. That is what Siena users have asked for.
Thank you to our German and Japanese customers and partners for bearing with us, it's here now!
This is the first of many other languages that we will support.
