Update as of 6th December 2015:
-updated mod to 1.14
-added an event, that removes Zombie Horde when they both have "Zombie decline" modifier and have less than 50k troops.
-added "plz support me on patreon" to welcomming event
-fixed a bug, in which every nation had zombie units as their base ones (this also means a huge zombie buff, since their unit pipes actually matter)

Patch 0.ittookmetoolong
Long awaited, has some important things:
-3 new difficulty levels
-4 new units caps
-2 start up evnets that define difficulty
-got rid of annoying notifications in-game
-blocked zombies from spawning at some random locations without access to anything
-hopefully fixed a bug when a nation would not come to war with Undeads

Fixed a bug about event zi.44 firing all the time.

Hotfix 0.2.1
-fixed English and Japanese event about giving up on their continents
-hopefuly fixed a bug, where uncolonised provinces had large colonies and were occupied by natives

Patch 0.2
-raised morale and pipes of the zombie troops, while lowering the attrition, to buff them, as they were too weak in earlier versions
-added a specail modifier called "Zombie capital" to the capital of the Zombie horde (duh), that raises supply limit by 1000 so the initial doomstack does not die to attrition anymore
-added an event adding the trade goods to the colonies, after they're taken back from the zombies, earlier the biggest bug in-game (graet thangs to Omicron for helping with this one)
-added new event for Japan, to give up on Asia and abandon the fight against Zombie Horde (it fires for Japan, and it effects everybody who has all provinces within the Japanese region)
-fixed a bug where zombies spawned on Iceland
-added a bunch of relations modifiers for zombie horde, so they should not receive subsidies from Ottomans anymore

Litle patch at noon:
-buffed zombie horde
-added German localisation by lemonporn

Fixed a bug, when after the collapse of the horde, nations would be still at war with it, causing CTD.
