The game's Demo version has been updated to be compatible with the full game.
Unfortunately this means any ongoing saved games will no longer work, however anyone who wants to continue a saved game can activate the legacy1.1.7 version through the following method:
Go to "Islands of the Caliph > Properties > Betas" and select "legacy1.1.7" from the drop-down menu if you want to continue your saved game.
Going forward there should no longer be any changes that will require a new saved game. Sorry for any inconvenience!
Soundtrack
You may have noticed that the Islands of the Caliph store page now allows you to get the official soundtrack. If you enjoy Hugo Rodrigue's beautiful music, please consider purchasing the soundtrack.
