OK, we will work on the update.
FYI...We are working on the country maps for Sudan and South Sudan. Then we will update the world maps. However, none of these new maps or the world map updates will be finalized until the new country is assigned a 2-digit country code, which may take a bit. As soon as someone knows what that official assignment is, please post it here with a link to the source and we will finalize the maps for Sudan/South Sudan.
We will issue a country map for South Sudan and another for Sudan soon. We will use "SS" as the country code until an official one is issued and change it for the country map if necessary.
However, we will not update any of the world maps until an offical country code is issued. Country maps are much easier to update twice than the world maps.
