The new version of the software/website doesn't offer anything related to the supported languages. You can install it, but only after the product has been acquired/purchased from its official website.
I've seen a Setting button on the main interface of the software, but since I don't have access to the software's installation package, it's impossible to say if it supports German language or not.
