在等游戏出来以前，官方先分批次公布了总共长达十八页的更新摘要，以下只加注一些
我个人觉得比较重要的：
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).
一国得到的顾问等级将依照国家财力而定，穷国不再拿到一堆聘不起的二三级顾问；
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.
自治度高低对省分的税收、生产与人力影响将更显著；殖民国后期削弱
- Reduced impact of local autonomy on recruit and ship building times.
# Buildings
- Increased base number of buildings per province from 1 to 2.
每个省份可以盖的建筑至少都有两栋啦；大建设时代
- Removed build cost increase from tropical, arctic and arid (still has
development cost penalties).
在烂地形盖建筑物的价格现在和其他地形都一样了
- Arctic provinces now have 1 less building slot.
- Farmlands now only has +1 building (down from +2) but is 5% cheaper to
develop.
farmlands地形对发展度的影响将从原本的+15% dev变成-5%dev，影响最大的大概就是北
德地区了
# Capital
- There is now a -5% per 100 country development bonus to development cost in
the capital province.
国家总发展度越高，发展首都就越便宜
- 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.
转文化会惹恼同文化的人
- Changing a province's culture is no longer blocked by primary tag of that
culture existing (exported to defines, default 0).
洗地在多人连线时彻底废了
# Diplomacy
- Removed opinion penalty for Competing Great Power as it has little effect
and is frequently nonsensical in the early game.
恼人的列强竞争（-25友好度）终于要掰了
- 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.
现在会与你破弃的同盟间有五年的停战期（与撤销保证独立后效果相同）
没办法在依照战况就立刻破弃并攻击原本的同盟了，除非能接受降稳定
*感谢kakuj大的指证
- 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).
无法再在战争和谈画面割让AI不想要的地给AI；以往如果AI不想要的地它顶多只你无法
将这块地卖给它，现在连和谈时割让给它都不行，养小弟变困难
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尔内战的国家灾难
- The Janissary Decadence disaster will now only trigger 100 years after the
Janissary modifier is acquired by the Ottomans.
禁卫军衰弱会比较晚出来
# 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时间才能恢复
- 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.
被发现的伪造宣称会要花原本四倍的时间才能造完
- Local Spy Defense is no longer a factor, instead all spy factors are global.
间谍效率现在没有区分进攻与防御了，只有统一的间谍效率；间谍理念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.
补兵免钱现在是游牧的政府形式而非游牧国的理念；游牧国一旦完成政府改革脱离游牧
，就会失去免费补兵的能力！ 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.
贵族共和变废
- Hordes no longer take a prestige loss for selling provinces, returning
provinces and releasing vassals peacefully.

cost.

inflation.
- No longer possible to pick Naval or Maritime ideas for Primitives.
原住民没办法再选海军相关理念
- Replaced Quantity: National Arsenal with "Mercenary Contracts", giving +50%
possible mercenaries.
数量理念修正，原本+25%海军上限被换成+50%可雇佣兵数量，对陆权国来说数量理念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.
数量+扩张理念的政策不再是+1殖民队；配合前述数量理念的修正，海权国现在选数量理
念的效益大幅降低
# Mercenaries
- War taxes now increases possible mercenaries by 10%.
战争税现在会提高10%可雇佣兵数量
