- City of Bhavnagar was added and the Ahmadabad harbour was moved there
- A little overhaul to Warszawskie state, it got a little smaller, some forests around Warsaw were added, Okęcie airfield is now where it should be, Praga district is now present and finally infrastructure level was lowered by a single level cause Warsaw is an urban nightmare of a city
- Changde is no longer as important as it once used to be
- Croatia from now on has cores on Dubrovnik, Neum and Hercegovina, during the Trieste-Croatian coast exchange with Italy they shall receive also these 3 states
- Changsha got more important than it used to be, but there is more important cities (some of them weren't even considered cities up to this point) like for example: Guangzhou, Taiyuan, Wuhan, Hanoi, Vientiane, Phnom Pheng, Kabul, Herat, Hyderabad, Bombay, Bangladore, Madras, Dacca, Calcutta, Rangoon, Pantha, Delhi, Ahmadabad, Lahore, Nanning, Haiphong, Jaipur, Lucknow, Saigon, Vucovar, Debrecen, Budapest, Zagreb, Fiume, Zara, Banja Luka, Spalato, Pola and Dresden
- Polish-Slovakian border was adjusted to include the town of Zakopane and Polish parts of Spisz and Orawa
- Island archipelago next to the Croatian coastline is now accessible by Spalato and Dubrovnik
- Trieste peninsula has become more urbanised and it is reflected by one more victory point being added there, the town of Capodistria
- Bucovina is no longer split into 2 states, but in exchange some part of it was given to Poland
- Changes to Hungary, let's goooo!!! The 2 states of Banat were split into 3 states, a South, East and North Banat that belong to Balkan Federation, Romania and Hungary respectively. State Korosvidek became much larger covering whole area of what is now central part of the new Hungarian-Romanian border. State Alfond became much smaller. North Transylvania became smaller, with some of its provinces going away to Korosvidek and Transcarpathia, state Szeklerland was created also of some of former North Transylvania provinces. Hungary helds cores on North Transylvania and Szeklerland. North Hungary became larger in order to include whole area of Budapest. Transdanubia was split into 2 states. South Hungary is now much larger and cover whole area between 2 rivers. Bohemia now controls half of Slovakia as West and Central Slovakia are now theirs, while South Slovakia and newly created state of East Slovakia remain under Hungarian control. The city of Sopron was moved out from Burgerland to Transdanubia where it should have been, while the state of Burgerland, formerly Orvidek became Austrian. Several provinces along Donau became marshlands. Towns of Nagyvárad, Brezno, Eperjes and Nagybánya are now included in the game, as well as victory point of Sibiu and Tîrgu Secuiesc. All focuses and decisions were adjusted to these changes where needed
- Virtually all states of the Denubian Federation (Austria, Bohemia, Hungary, Croatia and Trieste) were changed and slightly buffed even. From now on the population of the Federation shall be larger (reaching around 45 millions of people after territorial exchange with Italy). The industry of the Federation has been rebalanced in such a way so neither of the member nations would be significantly stronger than others, with most significant buff going to Croatia (tho it's mostly dockyards for them) and greatest debuff going to Hungary that already became smaller this update. Also which is pretty important, the Trieste-Croatian coastline exchange with Italy became more fair for both sides as now Italy receives a much better and worth taking version of Trieste that they immediately gain cores on in exchange for giving up Croatian coastline that shall significantly boost any future Croatian attempts at being significant
- Vltava river is now running through Bohemia
- The city of Lahore was moved to its correct location and has got some special treatment
- Brandenburg has been split into 3 separate states: Magdeburg, Berlin and Frankfurt-Oder
- Łódź state is now considered a metropolis, it also got bigger
