If you've looked at the map very recently, you may have noticed several changes. Firstly, we have a key now! All resources for the Old and New Worlds are labeled for easy identification, so don't worry about playing Civ V with More Luxuries enabled just to understand my map!

Secondly, a multitude of new resources have entered into the world! Most of these will be used in the New World (that's a thing that is happening, by the way), but there were several changes to the Old World as well!

• The people of South Ullr looked closer at their bananas, and realized they were actually coconuts!
• The people of South and Central Ullr squinted hard at their cattle, and realized they were actually fowl!
• The people of South Ma'at tasted their chocolate, and realized it was actually nutmeg!
• The people of Central Ma'at held their amber up to the light, and realized it was actually quartz!
• The people of Vinayaka put truffles in their mouth, then spit them out when they realized they were actually furs!
• The barbarians of Caledonia pet their sheep, only to find out they were actually cattle!

Additionally:

• Stone is now a military resource
• Ivory has been renamed Elephants, which is now a military resource

No nation's resource diversity has been changed in the course of these alterations, so don't worry. If you have stone or elephant in your territory, wait a day for the spreadsheet to properly update.
