Version 3.08
Hard Difficulty - Your vassals are more rebellious and your domain suffers from corruption, making the game considerably harder for the player.

Increased the influence costs for requesting governor support and added a one-year cooldown to the character interaction.

Reduced some of the buffs in the Challenging AI mode, to account for AI conquerors.

Version 3.07
Imperial Armies - In an administrative realm, characters can call on the armies of other governors at the cost of influence. The influence cost scales based on the military strength of the administrative vassal.

Shifting Loyalties - Vassals that join a war can be bribed to withdraw their armies in exchange for payments of gold or by leveraging a hook, though at the risk of angering their liege.

Vassal Directives - Several vassal directives are unlocked for all government types if the host owns the Roads to Power DLC.

Allies will be less eager to join your wars and calling them is now more difficult, especially when you are the aggressor.

Version 3.06
Military Support - A liege can ask one of their direct vassals to join a war in exchange for granting them a hook.

Power Blocs - Vassals can leverage their existing alliances when forming factions, promising mutual aid in the event of a civil war.

House Assistance - House members can offer to join the wars of other house members, even without an alliance.

Pursuit of Power - Powerful vassals will be a lot harder to satisfy, requiring careful management and strategic alliances to prevent civil wars.

Vassals are now much more likely to refuse a call to arms for external wars when they have nothing to gain or lose from the war.

Version 3.05
Levy Damage - The damage stat of levies is increased to 11/12/13/14/15/20, allowing them to deal more damage in combat.

Levy Toughness - The toughness stat of levies is increased to 11/12/13/14/15/20, allowing them to sustain more damage in combat.

Levy Maintenance - The maintenance cost of levies is reduced by 25%/50%/75%/100%, lowering the burden of raising many levies at once.

Men-at-Arms Upkeep - The maintenance cost of Men-at-Arms is increased by 25%/50%/75%/100%, making it more expensive to maintain a large retinue.

Men-at-Arms Cost - The recruitment cost of Men-at-Arms is increased by 25%/50%/75%/100%, raising the investment needed to create a sizeable retinue.

Version 3.04
Realm Politics - During a civil war, vassals can be persuaded to choose or switch sides by using gold, prestige, hooks, prisoners, and alliances.

Liege Intervention - A liege can now intervene in a war involving their direct vassals, but at the cost of incurring tyranny or losing prestige. Help your vassals in expanding the realm or squashing internal wars to maintain stability when necessary!

Alliance Fatigue - Each time an ally is called into a war during their lifetime, they become less willing to accept subsequent call to arms.

Mercenaries - The cost of hiring mercenaries and holy orders are increased by 25%/50%/75%/100%, making it harder to amass an army.

Empire-tier realms now have six powerful vassals instead of five, increasing the difficulty of keeping them stable.

Version 3.03
The War Declaration UI has been completely reworked. It now displays the total strength of the vassal participants on each side, the reasons for why a vassal joins the war or declines their call to arms, and the vassal's primary title.

Title Holders - When a vassal would lose any of their titles as a result of a war, they will be called to arms.

Enable/Disable Call to Arms - You can now disable your vassals from being called into your wars temporarily by using a decision, which can help you avoid War Exhaustion penalties.

Capturing direct vassals of a war leader will now grant 2% war score for each vassal captured by the opposing side.

Each time a civil war happens in a realm, vassals will receive an "Internal Turmoil" opinion penalty to represent the recent instability. There is a new game rule added to disable this.

War Exhaustion penalties now vary based on why a vassal was called to arms (i.e if they are just bordering the enemy realm or if they have a vested interest in it).

Added a global variable for More Interactive Vassals that other mods can check using "has_global_variable = miv_is_loaded", which should make compatibility patches easier.

Version 3.02
Defiant Vassals - Vassals can refuse to join a war based on their relations with their liege, and can also block their own vassals from joining.

Treacherous Vassals - When allied with the opposing side, vassals can be called to war against their own liege and vice versa.

The war declaration UI will now indicate which vassals decline their call to arms, rather than not showing them in the list at all.

Civil War Rebalance - More vassals will remain neutral during civil wars.

Off-by-default game rules now indicate the default value for clarity.

Version 3.01
Garrison Size - The size of all garrisons can be reduced by 25%/50%/75%/100%, shortening the time it takes for an army to siege a holding.

War Participants (Off by Default) - War participants who join a war after it starts can call their own vassals to arms, though with much weaker obligation.

Opinion Modifiers can now stack, calling vassals into too many wars will greatly decrease their willingness to join you.

Peasant uprisings and similar levy-based rebellions will now scale based on the Levy Reduction setting.

Cleaned up a lot of the mod's code. Error and debug logs should now be a lot cleaner, and game performance should be smoother as a result!

Version 3.0
Levy Size - Levies from all sources can be reduced by 25%, 50%, 75%, or 100% to place more emphasis on the Men-at-Arms counter system and reduce overall army sizes.

Levy Reinforcement - The rate of levy replenishment can be reduced by 25%, 50%, 75%, or 100%, making losses from combat more impactful.

Bannermen (Off by Default) - All direct vassals are eligible to be called to arms, but with a much higher chance of declining based on several factors.

Indirect Vassals (Off by Default) - In a civil war, a vassal may call on their own vassals to support their commitments to the loyalist or rebel factions, who will accept or decline based on several factors.

Levy Contribution - The amount of levies that vassals provide to their liege is reduced by a multiplier of 25%/50%/75%/100%.

Updated the descriptions for the custom game rules in this mod.

Added a new game rule category to organize the custom game rules in this mod, making it easier to find and configure them in the settings menu.
