What's Gone: complicated formula for exporting maps, the web export, maintaining a Tiamat balance.
What's New: new payment model based on exports and tiles, 1 free export a month, buy additional exports and or tiles from the rpgobjects store (or rpgnow).
With that said, I'm off to work on the next Abandon All Hope adventure and the Savage Worlds campaign guide. And then... Tiamat Update 16. :)
