在等遊戲出來以前，官方先分批次公布了總共長達十八頁的更新摘要，以下只加註一些
我個人覺得比較重要的：
Patch Note 1
# Advisors
- Countries with incomes less than 10 ducats will no longer get level 2
advisors (except by event) and countries with incomes less than 50 ducats
will no longer get level 3 advisors (except by event).
一國得到的顧問等級將依照國家財力而定，窮國不再拿到一堆聘不起的二三級顧問；
合理修正
# Autonomy & Cores
- Development levels over 30 no longer contribute to higher coring and
culture conversion costs.
- Refactored local autonomy to apply multiplicatively to manpower, tax and
production rather than additively. This makes effects of LA more severe.
自治度高低對省分的稅收、生產與人力影響將更顯著；殖民國後期削弱
- Reduced impact of local autonomy on recruit and ship building times.
# Buildings
- Increased base number of buildings per province from 1 to 2.
每個省份可以蓋的建築至少都有兩棟啦；大建設時代
- Removed build cost increase from tropical, arctic and arid (still has
development cost penalties).
在爛地形蓋建築物的價格現在和其他地形都一樣了
- Arctic provinces now have 1 less building slot.
- Farmlands now only has +1 building (down from +2) but is 5% cheaper to
develop.
farmlands地形對發展度的影響將從原本的+15% dev變成-5%dev，影響最大的大概就是北
德地區了
# Capital
- There is now a -5% per 100 country development bonus to development cost in
the capital province.
國家總發展度越高，發展首都就越便宜
- There is now an increased cost for moving your capital to a province with a
lower development than your current capital, higher the more total
development you have.
# Culture
- You now get a relation hit with every country that has the primary culture
of the culture you are culture converting.
轉文化會惹惱同文化的人
- Changing a province's culture is no longer blocked by primary tag of that
culture existing (exported to defines, default 0).
洗地在多人連線時徹底廢了
# Diplomacy
- Removed opinion penalty for Competing Great Power as it has little effect
and is frequently nonsensical in the early game.
惱人的列強競爭（-25友好度）終於要掰了
- Increased opinion impacts of rivalry.
- Monarchies that are allied to revolutionary target now still get the
penalty for a Revolution.
- Breaking an alliance now gives a truce for 5 years between the nations
breaking it.
現在會與你破棄的同盟間有五年的停戰期（與撤銷保證獨立後效果相同）
沒辦法在依照戰況就立刻破棄並攻擊原本的同盟了，除非能接受降穩定
*感謝kakuj大的指證
- Removed the 'Has Casus Belli' opinion modifier and increased opinion
effects of having cores and claims, as the former did not mesh well with
Imperialism CB in late game.
- There is now a +50 opinion bonus with a neighboring country if you both
border a more advanced neighbor (advanced as in it fulfilling tech group
requirement to protectorate you).
- Signing an alliance now removes the rejected alliance modifier between the
countries.
- No longer possible to select peace treaties for allies that do not want
them (ie, can no longer feed unwanted provinces to AI allies).
無法再在戰爭和談畫面割讓AI不想要的地給AI；以往如果AI不想要的地它頂多只你無法
將這塊地賣給它，現在連和談時割讓給它都不行，養小弟變困難
Patch Note 2
# Disasters
- The Castilian Civil War disaster is now a disaster exclusive to Castille
(unifying Spain in time will allow you to avoid it).
只要成立西班牙就可以避免卡斯提爾內戰的國家災難
- The Janissary Decadence disaster will now only trigger 100 years after the
Janissary modifier is acquired by the Ottomans.
禁衛軍衰弱會比較晚出來
# Economy
- Protectorates, Colonial nations and Personal Union juniors no longer have a
penalty to their development cost, only vassals and marches.
- Provinces now take longer to start recovering from being looted.
被劫掠的省分要花更多時間才能恢復
- Provinces that have hostile units still standing in them will no longer
recover from being looted, even if they have run out of loot.
# Espionage
- Fabricate claims will be four times slower for the remaining duration if
discovered.
被發現的偽造宣稱會要花原本四倍的時間才能造完
- Local Spy Defense is no longer a factor, instead all spy factors are global.
間諜效率現在沒有區分進攻與防禦了，只有統一的間諜效率；間諜理念buff
# Exploration
- Countries with their capital in a colonial region can now auto-discover
provinces in colonial regions, since they can't use hunt for the seven cities.
- Reduced frequency land exploration events not relating to the Seven Cities
of Gold.
# Governments
- Iqta now gives +5% global tax modifier instead of +100% heir chance.
- Tweaked the bonuses of tribal governments to be more balanced towards each
other.
- Free reinforcement for Nomads is now tied to the Steppe Horde government
form instead of ideas.
補兵免錢現在是游牧的政府形式而非游牧國的理念；游牧國一旦完成政府改革脫離游牧
，就會失去免費補兵的能力！ 游牧nerf
- Noble Republic is now a very unattractive form of government that requires
a very high percentage of land grant to nobility and can only be changed out
of with a decision.
貴族共和變廢

provinces and releasing vassals peacefully.

cost.
- Colonial Ideas now start with -10% development cost instead of -0.1
inflation.
- No longer possible to pick Naval or Maritime ideas for Primitives.
原住民沒辦法再選海軍相關理念
- Replaced Quantity: National Arsenal with "Mercenary Contracts", giving +50%
possible mercenaries.
數量理念修正，原本+25%海軍上限被換成+50%可雇傭兵數量，對陸權國來說數量理念buff
- Buffed mighty Gotland's ideas.
- Reduced the power of Colonial Ideas' 'Religious Outposts' from +3%
missionary strength to +2% missionary strength.
- Policy for Quantity + Expansion now increases land forcelimits instead of
giving an extra colonist.
數量+擴張理念的政策不再是+1殖民隊；配合前述數量理念的修正，海權國現在選數量理
念的效益大幅降低
# Mercenaries
- War taxes now increases possible mercenaries by 10%.
戰爭稅現在會提高10%可雇傭兵數量
