"Added support for localization asset bundles"
What does this mean?
Sounds to me like the app can now download "asset bundles" (text/images/voice) which have been localised, rather than having all the various different languages built into the app itself.
This will keep the total size of the app down (good for devices with little storage) as you don't have to download loads of localised content you don't need.
But it also seems to indicate they can add other languages later without having to release a new app version to all the stores... I may be wrong there as I haven't had a chance to check out the new app yet, but it reads that way to me. Hence the mention of needing internet access for the German content.
