Besides bugfixes and the like, version 1.3.2 brings a number of important improvements to the game. Potions of healing can now be bought, a new upgrade has been added for each civilization, and a new background has been added.
After upgrading to a Burg or a Bastion, you will now be able to buy potions of healing for 150 gold apiece:
A "Writing" upgrade has been added to both civilizations; in RTS mode it increases research speed by 10%, while in Grand Strategy mode it increases the Research income by 50%. Additionally, the writing upgrades transform tribal factions into polity ones: if you are playing with the Frank Tribe and research Writing, you may become the Francia faction.
And a gryphon background is now available in the game (for the Steam version only):
Additionally, the dwarves now have one new quest ("The Binding of Grafvitnir"), in which they must save their clan from the jaws of a monstrous wyrm.
The grand strategy mode has also underwent a number of mostly performance-related improvements, and the AI now allocates its troops much more efficiently.
