As to what is included in the update, there are some major changes coming which we've talked about in the past: First of all the replacement of every single asset with new art from Caeora. If you want to know more about the redrawing of the asset, take a look at our last Mapping It Out from September.
In that stream, we also showed off another huge addition and change to Deios: the new Tectonics system. So if you haven't seen that yet and want to get a preview before the update launches, our last monthly stream is where you should look.
The one thing that we hadn't shown off before is the new Clipboard and the River systems. Users will now be able to draw and adjust rivers in their maps, adjust the flow of the rivers, and even combine several rivers together to create intricate and wonderful designs. In addition, the Clipboard system allows users to copy and paste anything from single assets to entire continents both on a single map but also between maps.
This update is massive, and there are a LOT of changes, so please, again, make sure to backup your maps before updating! And once the update rolls around, let us know what you think of the new systems!
