So far the big three of online mapping: Google, Bing, and OpenStreetMap have not recognized the change. None of the Russian map services I know of show the change yet, either. Like South Sudan this blog will monitor for any changes.
Changing European borders also give the excuse to show the Last Express closing credits. If you have not played the game on PC ($5.99 on GOG) it is now available for iOS and Android. I strongly recommend it.
