Update 1.4.3 - Large school, Large hospital, New skyscrapers
NEW Added a large hospital with a capacity of 800. (2.5x the default stage 2 hospital). Unlocks with 200,000 city population and 95 health score. Added a large elementary school with a capacity of 5,400. (3x the stage 4 school). Unlocks with 150,000 city population. Added stage 6
NEW

Added a large hospital with a capacity of 800. (2.5x the default stage 2 hospital). Unlocks with 200,000 city population and 95 health score.
Added a large elementary school with a capacity of 5,400. (3x the stage 4 school). Unlocks with 150,000 city population.
Added stage 6 retail buildings. Require 1,800 points of retail demand to develop. Pre-update retail buildings must be manually rezoned (destruction not necessary) to force the new max stage to be set.
CHANGES & BUG FIXES

Roads were not connecting automatically with existing adjacent tiles.
Redesigned ground/underground rail connector. Rails should now visually connect properly.
Enhance zoning tool accessibility.
In some cases tooltips were not staying on screen for more than a few seconds and so could not be read.
Improved shadows at far distances.
Increased visible amount of cars, trains and pedestrians.
The speed at which the amount of printed money decreases is now displayed in the budget window. Added tooltip.
The speed at which the amount of printed money decreases is now based on the inflation rate and the cash flow (increments of 15% of the current cash flow when the inflation is near zero). Printed money only decreases if the cash flow is superior to +$10. [requested by MotionMan51 and Romulo]
Increased by 50% the effect of printed money on the exchange rate.
Fasten speed at which piled up trash is collected.
If not unpaused after loading a city the balance cash flow was incorrect.
Updated tips on loading screens.
Changed the first two texts of the tutorial to give a little more background about the game.
Changed some news title for more accurate and useful information and added new lines for when there's nothing to report.
News submenu scrolling was painfully slow.
Scrolling in any UI elements no longer affects the camera.
Sped up keyboard zoom.
Closed ports and airports were still counted for the total trade capacity.
Changed the number and type of jobs created in arcologies. Now for every 100 occupants: 3 retail jobs, 6 office jobs and 14 high tech jobs. Census tool was displaying incorrect number of jobs. [reported by Omnius]
Decreased the number of office jobs induced by each advanced manufacturing job by 6%.
Slum dwellers now create retail demand too.
Increased pollution emitted by coal power plants and incinerators.
The balance red warning icon was displayed too late and inconsistently.
Facilitated placement of wind turbines (tool now shows 6x6 borders).
Graph for GDP was getting inverted for very high values, now clamped at 2 billion (visual only). [reported by Romulo]
Calendar year now starts at 1 instead of 2021 (for new cities).
WHAT'S NEXT
11 major updates with new content and 17 smaller patches have been released since the game's launch in September 2021.
I've been monitoring feedback, reviews, refund requests and sales number very closely in the last months so as to take a decision regarding the future of Citystate II. Now I've got one good news and one bad news.
The bad news first. Despite the updates and some marketing efforts, sales and feedback have not improved much. Continuing to work on Citystate II is therefore becoming a little riskier on the long term. The most common requests such as mod support and curved roads cannot be added to Citystate II without having to remake half of the game. I also realized that the complexity of the game itself and
the lack of sandbox features makes it really difficult for it to reach a broader audience.
But here's the good news. Citystate II has sold enough copies since launch that I can confidently invest the next couple of years at least into the development of a new game.
Development of a third Citystate has in fact already begun. To help me figure out some of the core game design choices and if you want to know more about my plans go ahead and fill out this short survey.
Minor updates to Citystate II should still be expected so if you encounter any bug please let me know!

Bug fixes

Very large cities were running at low FPS. Fixed an issue with the pathfinding methods of service and emergency vehicles and decreased their spawning rate.
Floating building: When a public housing was abandoned (happens if the low class demand is negative) the building position was not being saved correctly and could be seen floating in the center of the map. This does not fix the buildings that were already floating before the update, for that you need to manually bulldoze the area they were occupying.
Day time mode is now saved.
Some tutorial steps had no text [reported by yipei]
Improved cities name readability in the Nation view [requested by Elia1799]
Stadium and Pool could not be unlocked if most of the middle class was living in arcologies [reported by yipei]
Increased max zoom out distance, decreased fog density. [requested by Romulo]
Various changes to the textures of windows. Improved reflections.
Solar farms were lighting up like windows at night.
What's next
Another update is on my roadmap and should come out within 3 to 4 weeks. Larger schools, larger hospitals and retail level 6 are on the menu.

NEW

Added Waste Management. Garbage disposal facilities become required above 7,500 population. 3 options: A landfill (cheap but very low capacity), an incinerator (heavy pollution, high capacity) and an eco-incinerator (low pollution, expensive, very high capacity) which unlocks with 50,000 jobs in advanced manufacturing. When waste treatment capacity is exceeded, trash will start to pile up on public roads which will decrease the land value and the environment score.
Added school bus, garbage truck and police car. All special vehicles can now be seen roaming the city and are parked in front of their respective buildings.
Added German localization (Provided by Greetings Rony).
CHANGES AND FIXES

We can now build multiple service buildings (schools, solar farms, …) at once without having to reselect the tool [requested by Rumi]
The amount of underground resource is now displayed when building a mine even without road connection [requested by Rumi]
Retail buildings can no longer be automatically converted to offices, making stage 6 offices easier to get.
Increased the positive land value effect of office and retail buildings.
Slightly increased tax collected from mixed used buildings.
Decreased demand for office (-5%) and decreased jobs created by the upper class (-2%).
Population in arcology was not counted in one of the middle class economy algorithm. This will probably affect retail demand if you have lots of arcologies. [reported by Rybodhi and Omnius]
Population in arcology was not counted in the lower UI panel $$ total Population and for the middle class graph. [reported by Romulo]
Added a 'Do Not Quit The Game' text on the loading screen when something is being written to the disk.
Ploppable buildings could still be placed even if the terrain was too steep [reported by Romulo]
Tooltip for "terrain too steep" was not being displayed for large buildings.
Changed all parks icons.
Corrected security score tooltip warning.
We can no longer create RCI lots under water.
Graphs: replaced pop growth with traffic, replaced GDP growth with environment score, increased precision of the birth rate.
Added environment and traffic scores next to the layer buttons.
The mixed use zoning tool was getting locked when the middle class was entirely replaced by the upper class [Reported by Romulo]
The mine placing tool was colored green even in suitable locations and the tooltip for unexplored area was missing.
Increased font size of the lower UI left and right detail panels.
Updated PT-BR and Spanish translation for Property Tax [reported by Romulo]

A quick summer patch fixing up what you guys have reported in the last weeks.

Fixed several issues affecting highway access roads. Highway were being destroyed when surrounding roads were changed. It was not possible to build a highway access if the road was built before the highway.
Blur effect was not turned off after closing the load/save nation menu. [reported by Zaid, Dictator and Rommell]
Improved the computation of the inequality index, especially in cases where the upper class is bigger than the middle class. [requested by Romulo]
The game was in some cases freezing in huge cities that have too few intersections. AI pathfinding has troubles finding a path to its destination when the road network has too many bottlenecks. The lot will now get abandoned (after 5 attempts) instead of freezing the game. [reported by Romulo]
Residential buildings now try to reach up to 5 different workplaces before triggering a "Can't reach workplace" warning.
Retail buildings were upgrading to stage 5 even if the density limit was set to 4 [reported by Dictator and KenanYK]
Lowered demand requirement for office stage 6 from 3000 to 2600. [requested by Omnius]
Lowered value requirement for mix $$$/Office stage from 5100 to 4600. [requested by Drai and Omnius]
Clamped maximum city balance to 2 billion to prevent integer overflow (value was reverting to negative 2 billion) [reported by iaido_warrior and Dictator]
Population in arcologies no longer uses the city schools and hospitals. Arcologies now consume electricity. [requested by Dictator]
Jobs in arcologies were not being added to the total number of jobs available. [reported by Dictator]
Decreased tax income from arcology by 50% (to be in par with middle class tax income)
Nature and ocean ambient sounds were still being played even if the volume was set to zero. [reported by Growler]
Decreased distance at which park sound fx can be heard.
Several mixed use buildings had faulty colliders which prevented warning signs to be displayed and vehicle collision.
The traffic congestion value in stats was displayed in green when exceeding 100%.
Update 1.4.2 should come out by the end of September / early October.

NEW

Added a public pool
Added a wind turbine
Added beach props
Added a tennis court
Added a holodeck building
Added a slider to manually set the exact time of day.
Added arrows above functional road connections.
MAIN FIXES AND CHANGES

Commutes are updated more often and look for closer workplaces in large cities to reduce the chances of "Can't Reach Workplace" abandonment. => When working on large maps especially, avoid long stretched building blocks with few intersections, check if avenue and rail tracks intersections appear correctly and do not put jobs excessively far from houses.
Improved pathfinding. Commuters will choose the road with the highest capacity first, if same capacity commuters will choose the road with the least congestion.
Increased land value propagation around mixed use buildings (has an effect on their own value and security score too).
Increased effect of security and health scores on land value by about 40%.
Smooth terrain mode were creating holes in terrain around roads and buildings. Terrain in default mode was creating holes in-between beaches and buildings. [reported by Rommell]
Increased the speed at which decayed or looted buildings and parking lots are getting rebuilt in large cities [reported by Dictator]
When a mixed use building was transformed into a parking lot, the number of employees was not reset to zero. [reported by Dictator]
Changed the requirement for the silicon achievement to "100,000 jobs in advanced manufactures" (before: 90% of all jobs needed to be in AM). [reported by MagOliven]
Improved the way roads level the terrain. Roads were often built lower than their surroundings. Moreover, at the lowest land height road intersections were not leveled with adjacent road tiles.
When upgrading or downgrading roads, different road styles were getting mixed up around intersections.
Road connection tiles could not be destroyed. [reported by Dictator]
Reworked the system of job sharing across cities. In most situations, cities will now share more jobs. => A maximum of 5% of total local jobs can be found in a neighbor city. The higher your unemployment rate the more citizens will try to find jobs outside the city. The neighbor city does not need to have a low unemployment rate to share its jobs. Remember that jobs held outside the city indirectly lower your tax incomes since the hiring businesses are not taxed locally.
MINOR CHANGES

Max business demand growth increment now set at 100 for population above 2M (before: 54) [suggested by Dictator]
Vacant commercial and industrial lots were shown as residential lots in land use layer [reported by Dictator]
Trees are now getting transparent when the terraforming tool is active [suggested by Omnius]
Corrected all parks cost and capacity tooltips on buttons. Improved data readability.
Fixed car reverse camera and default pitch angle. Improved handling slightly.
Max dollar reserves can now reach exactly 2,000,000 [reported by Dictator]
A yellow warning is now displayed when a police or fire station is working over capacity (instead of when the security score is low). [suggested by Yipei]
Improved scaling of graphs for small values. [reported by Dictator]
Changed Nation view post process effects and sun position.
Stimulants and Dietary police didn't have a description. [reported by Dictator]
Increased number of occupants for low and middle class stage 5 and 6 buildings. [reported by Dictator]
Fixed more faulty props positions on RCI buildings.
Building multiple universities was not increasing the university capacity if we did not reopen the city [reported by Romulo]
Fixed a missing tooltip in the census tool for universities. [reported by Romulo]
The ocean sound effect was turned on and off too abruptly.
Fire trucks were not responding to fires if triggered by a helicopter crash or a riot.
Changed zoning tool tiles color to be more distinctive.
Increased (negative) effect of slums on police and fire service usage.
Road intersection in "T" were not allowing cars to turn in all available directions forcing commuters to make detours. Pedestrian crossings were also missing.
Removed several debug log entries that were unnecessarily allocating memory.
What's next?
I have a long list of small features and new buildings I'd like to add to the game but nothing super game changing should be expected at this point. The next update should arrive by September but small patches can still be released during summer.
If you want to report any bug or anything 'unpolished' please let me know:

A quick patch fixing a list of bugs (for once there were not so many of them and nothing major) and a short note to talk about the future of the game.
Fixes and Changes

Mixed use zones had a reduced security rating [reported by Aarki]
Slums had a hard time finding a spot to spawn.
Cleaned up debug texts in old census tool [reported by Omnius]
The new census tool was not displaying the correct icons for mixed use buildings.
A stage 2 mixed use building was offset. [reported by surreal cactus]
Reduced airport immigration capacity (-25%). Reduced base immigration flow (-15%).
The airport capacity was inaccurately retrieved to compute the bonus on immigration.
Fixed a rare missing road tile
Fixed a clipping issue affecting bridges and the new cliffs.
Corrected and added various prop and car positions on lots. (does not apply to anything built before this patch)
Reduced car engine volume. Removed gear change FX. [suggested by Elhoim]
The mayor's car was turning left slightly in a straight line. Improved car handling and follow camera angle. [reported by BiOxYdE]
The custom density button for mixed use zone was bugged. [reported by BiOxYdE]
Pollution from congested road now start to be emitted at 80% usage (before 100%). Maximum pollution now clamped at 320% usage (before 200%).
Updated news priority hierarchy. The conservatives will not congratulate you that much anymore.
Slight update of post process effects.
Traffic congestion number in stats was never green even when very low.
The StateCopter was spawning on a road just after taking the mayor's car for a drive.
I've received 2 reports pointing at issues with rail tracks but I was not able to reproduce the bugs on my end. This might be related to compatibility problems with older versions. I advise to zoom in when building rail tracks, so you can make sure the tracks have no holes and that intersections are built correctly.
I often don't take the time to thank or respond to each of you personally for your feedback and bug reports, you guys have been very responsive, your help has been decisive in fixing and developing Citystate. Thank you!
As some of you know my family and I will be relocating back from Asia to Europe in just a few weeks and so the rate of updates is expected to slow down during summer. I should still be able to put out a small update just before leaving. Besides, 2 other bigger updates are still on my roadmap but with no definitive release date.
This fall it'll be a year since the game initially released and at that point I'll have to decide whether I should work on additional content for Citystate II or if I'd better start working on a new project entirely.

Mixed Use Zones
We can now build mixed use lots. Work similarly to the classic RCI zones and have 4 stages. Developers can build 2 types: a mix of retail jobs and middle income housing or a mix of office jobs and high income housing. Since they require two types of demand, mixed use buildings are a bit more
difficult to grow. They also require higher land value than other buildings.
Mixed use buildings generate 50% less traffic. They can only be zoned once you have at least 3500 middle class citizens.
Added 26 mixed use buildings (heights range from 16m to 200m). Each building can spawn in 2 color variation.
Added a car driving mode "Grand State Auto".
Vehicles, buildings and roads have collision boxes. The player's car can be damaged. Comes with 2 camera positions (press "C"). The mayor's car can be driven as soon as you build your first road.
Added a Stadium (16x16, bigger than the university!). Unlocks with at least 150,000 middle income citizens.
Added a Museum. Unlocks when you have 40,000 upper income citizens.
Added 6 new maps (New Coastal and New Valleys). All come with large and truly flat areas that are easily buildable. Elevations are more detailed and realistic (heightmaps are taken from modified real world data instead of being computer generated).
Redesigned the upper UI and added 3 new categories: Leisure, Mixed Use Zone and Transport. Moved the census tool next to the news headline.
Rewrote the road construction tool entirely. More beginner friendly, adapts to almost any combination. Adjacent tiles now updates automatically when destroyed. (does not apply to avenues and highways)
New terrain blocks and new cliffs. Less cubic looking.
BUG FIXES & CHANGES

The screen was in some cases not being displayed fully with black bars on the sides. If you were affected you might need to open the city, go back to Nation and reopen it. Changed the way the last camera position is saved. [reported first by Be Kind]
Industrial and Commercial buildings were still counting walking commuters as if they were using cars. Improved road usage computation.
Changed GDP computation. Is lower with lots of low income citizens, higher with lots of high income citizens.
Built and unbuilt map tiles in Nation view had different coast lines.
Trees are now hidden when bulldozing too. [requested by Yannis]
Moved randomize city name button to prevent tooltip from overlapping.
Abandoned buildings were not displaying reason of abandonment in the new census tool.
Required land value and demand were not reset in the new census tool if the building was abandoned or transformed into a parking. [reported by Feywild Shaper]
The new census tool can now displays the reason why a vacant lot is not getting built and the citizen commuting distance.
Changed the computation of the park score, now "Parks & Leisure". Increased the effect of quality of life on immigration.
Reduced default speed of immigration in small cities.
Graphs for education, health, religion and others were not properly scaled. [reported by dictator]
Fixed a couple of typos. Fixed image compression issue for the intro credits. Fixed university requirement not turning green. [reported by Omnius]
Changed the initial cost of dollars, now only based upon the exchange rate. Increments of 20k. [suggested by Omnius]
When the Nation's data is missing or corrupted the game will now redirect you directly to the Create Nation screen. In some case the missing data was freezing the game. [reported by Dan R.]
Boats were unable to navigate close to the edges of the map, creating internal errors that might have led to more lag. [found thanks to Feywild Shaper]
Achievements could only be unlocked in a specific order. For example, you could not unlock Futurologist if you never unlocked Capitalist Overlord. This is just because of crap code, was not intended.
The futurologist achievement was waiting for 19 buildings to be unlocked instead of the existing 18 and could therefore never be triggered. [reported by Feywild Shaper]
Max immigration bonus from airport connection is now 100% (before 4000%).
Immigration effects for Least Advanced Countries were always 0% (UI only).
Icons in immigration panel were not matching texts [reported by Romulo]
Education yellow warning was disregarding high schools current usage [reported by Romulo]
Max demand growth step increased to 52 for all business demands (before 28) when population is above 1M [requested by Dictator]
Maintenance cost of pedestrian walkways increased to $5 per tile to match with parks costs. (Cost is added to transports, not parks)
The effect of ports and airports capacity on inflation was erroneous [reported by Jacob BD and Omnius]
Births from arcologies were incorrect and were messing up the global birth rate.
Births from slums were not counted.
If the economic freedom index exceeded 100, the government label was missing. [reported by Dictator]
The new census tool was sometimes showing health and education numbers for commercial buildings.
Replaced a track that was triggering a copyright claim on youtube [reported by OverchargedEgg]
Fixed a new memory leak related to terrain updates!
Leveling terrain could spawn grass underwater. Terrain modifications above ground now preserve existing vegetation correctly.

Fixed the infinite city loading screen:
If you were switching from a standard size map to a large map Nation the cities were created using the wrong terrain data.

In most cases the cities could not be loaded back. If you try to open these cities with the new patch the city will not load.
CHANGES

Zoning 3x wide lots only: Push Alt to enable when zoning. [requested by Bioxyde]
Water and power small bottom arrows are now colored yellow or red when approaching insufficient production.
Changed the usage of ports. Instead of the sum of exports and imports, only the difference between exports and imports is now taken into account. [requested by Omnius]
Increased the exports from advanced manufacturing by 16%.
The UI in Nation view now displays the current number of jobs actually shared with neighbors instead of the number of jobs that "can" be shared. [reported by Omnius]
Fasten terrain rendering.
BUG FIXES

Pushing Ctlr and Shift was always triggering the zoning click sound FX.
The dollar reserves was not reset when creating a new Nation [reported by SetArk]
Street lights FX were abnormally small.
Asphalt roads did not have foundations on slopes.
Improved the lot terrain leveling. Picks average height to better match the height with the road in front. This prevents some "no road access" issues too.
Light density had no cost [reported by Dictator]
Corrected PT-BR translation [reported by Romulo]
Added missing texts in the new census tool (land value and demand requirements to level up).
Alert messages were appearing and disappearing too quickly.

Camera's last location in city is now saved [suggested by phyziyx]
BUG FIXES

Improved performance in big cities. Was able to merge traffic lights with the roads to reduce draw calls (CPU). Colors of lights will disappear in existing cities.
If you had arcologies the park score was wrong. [reported by zunk and Omnius]
The zoning cost in the UI was often incorrect. [reported by Evinrunn]
Port could not be placed if it was facing a certain side of the map "Ship would not be able to leave the city..." [reported by Feywild Shaper]
When reloading the city traffic lights were often showing both green and red lights at the same time.
Improved the way the AI handles intersections with no traffic lights. Improved vehicles global reaction time and acceleration.
A city's map could be generated using the wrong terrain data in the Nation view (when using the default flag) [reported by WalebKassa]
High tech would in some case refuse to get built on vacant lots. Changed the way the system looks for the highest valued lot. [reported by Manatea]
CHANGES

Doubled the max output of fusion power plants (have to be rebuilt). [requested by Dictator]
Service buildings rating from usage now only decreases when above 90% (instead of 80%). Usage shown in yellow when above 90%. [requested by Dictator]
Zoning is allowed again with a negative balance. [requested by Kaynak]

Fixed an error that was preventing all industrial buildings from reaching stage 4. You need to rezone over your existing buildings for the change to be applied.
The maximum lot stage in the census tool was erroneous for all stage 1 buildings and non residential vacant lots. Rezoning was also screwing up this value. [reported by Dictator]
Music in city view was not playing. [reported by Kade B.]
The camera could not move freely along one side of the map. [reported by Omnius]
Increased starting Nation balance for all difficulties. [suggested by Omnius]
Offshore platform was displaying the no road access icon. [reported by Omnius]
Offshore platform was not displayed with the construction tool. Is now shown above water.
Prospecting tool displays the little squares above water instead of hiding them below. This fix also applies to the bulldozing and terraforming tools.
The resource layer was not displayed correctly above water. Disabled waves. [reported by MagOliven]
Zoning using the Ctrl and Shift alternatives gives more consistent lot sizes.
Improved the computation of the zoning costs. Was not taking into account density or lot size. Zoning is now blocked when balance is insufficient. [reported by Omnius]
The political affiliation slider on the new bottom panel was inverted [reported by BiOxYdE]
Clicking the water button was displaying the power heatmap [reported by Von K.]
A train arriving at destination and despawning could lead to unknown consequences (maybe froze the screen, maybe nothing). [reported by BiOxYdE]
Fixed several divide by zeros errors that were crashing the simulation (and the population count) if a new city with just a few inhabitants was saved and then reloaded. [reported by Dictator]
The graphic settings in Nation view was not updated with the new icons.
The population button above the population counter was offset [reported by phyziyx]
"Capacity" of pedestrian walkways was wrong in the UI. [reported by Omnius] (Clarification: The capacity of parks and walkways is not the visitor capacity but the effect on land value.)
Buses could not be clicked and followed.
The container port was not oriented correctly when built [reported by BiOxYdE]
Moved down the power and water use "%" so they are more visible and do not overlap with the warning signs.
Loading task text was not translated and just showed "Loading..." instead of "Loading Buildings".
Made road construction grid thicker. [suggested by Dictator and Eugenio]
Land value layer was turning green when the land value was really high [reported by MagOliven]
New census tool was saying "Birth rate" instead of Imports/Exports on commercial and industrial buildings.
Changed the color of walking commute paths to purple to be more visible [suggested by Eugenio]
Improved visibility of the data in the new panels [suggested by Eugenio]. Redesigned bottom UI slightly.
Improved the game speed selection buttons.
Improved colors of the zoning lots.
Alert messages were taking too long to pop up.
When the nation creator menu was open we could still interact with the nation map.
The 'Purchase Land' panel was showing tooltips from the 'Open city' panel.
Pollution was shown in the new census tool as having a positive effect on land value.
30 bug fixes in a patch. That must be a record.
I've been trying to put out as much content as I can in a short period of time so bugs are kind of inevitable.
I'm glad you guys are sending me all those bug reports though!

Added smaller and bigger lot types. 10 new lot sizes have been added to the existing 2 sizes, lot sizes now range from 2x4 to 6x6. This allows more variety and more 'organic' cityscapes.
The zoning tool have been redone to accommodate these additions, is now more precise and reliable, allowing to create one lot at a time of any size if needed. Press Shift while zoning to have narrow lots and Ctrl for wider lots!
20 new buildings have been added (17 residential and 3 commercial) to fit with the new narrower lot types. 2x wide lots can only accommodate buildings up to stage 4 for residential, stage 2 for retail and stage 1 for all other sectors. 192 variations of lot grounds have been added to fit all sizes, all sectors and all densities. Vacant lots have changed too, showing more clearly what type of zone we've built.

Added a new query tool. Any residential, industrial or commercial lot can be queried directly by clicking on the building. Automatically displays the commute path (draws a colored line above roads) of the selected building. Displays almost all info available and the exact land value and demand requirements needed for the building to progress to the next stage (buildings built before 1.3.0 will not have this info).
Added a follow camera. Any vehicle can be clicked and followed.
Added avenue/highway access road intersection.
Added new panels at the bottom of the UI. Can be shown or hidden. On the left: displays demand bars with details (current demand points and weekly change), includes the informal demand. On the right: displays the distribution of social classes, political affiliations, imports/exports and more.
Redesigned bottom part of the UI to improve accessibility/readability. Changed the main values displayed to highlight the most significant data. Simplified demand bars. Redesigned all buttons. Added warning signs with tooltips.

Added a pier with a Ferris wheel and a new park with a large flag in the center.
IMPORTANT FIXES AND CHANGES

Improved saving and loading time (30% to 50% faster with standard size maps).
Loaded city now launches in pause and UI loads the data back correctly. Evolution of demands is now paused until the city's data is fully loaded.
Decreased the number of prisoners by 10 and fixed the incarceration rate. Prisons capacity reverted to previous values. (Reported by Zarigan)
Fixed the computation of the park score. (Reported by Omnius)
Changed the computation of the property tax. Now takes into account the actual size of the lots. Property tax is displayed in the new query tool.
Doubled tax income and exports generated from mines.
Selling dollars was impossible if the amount was bigger than the current balance.
Faraway buildings will now be culled if 'Detail Distance' is set to low or medium. (Good for older CPUs and large, fully built maps).
Public housing will now get emptied when the low income housing demand is too low. Prevents exploits. (Reported by raxo8888).
Slowed down population default growth from births. Reduced the speed at which the social ladder transfers population from a class to another.
Households living in higher stage buildings now have fewer kids (Religiousness aside, the birth rate for a stage 7 building is 0.35pt lower than at stage 1).
OTHER FIXES

Multiple houses (Stage 1) could sometimes be built on the same lot.
"Can't reach workplace" building alert icon was wrongly displayed in some situations (after loading back a city and in new cities). (reported by Alex C., Kevin G.)
Citizens would sometimes prefer to commute by car instead of walking even if their workplace was within close walking distance. They will now walk if their path takes less than 32 road tiles to reach their destination (reduction of traffic to be expected).
Citizens walking to work now need a functional road system (walking citizens did not pathfind to their destination until now).
Vehicles were not able to U-turn when appropriate (reduction of traffic to be expected).
Removed a reference to Putin from the "Vodka Bar" retail banner.
Exports from farms is now based upon the size of the field. (Suggested by Omnius)
Placing farms on the corner of 2 roads was often impossible, only the fields were being built.
Zoning over a previously destroyed building was not possible in pause.
Helipads can now be destroyed. The helicopter should now spawn back on its pad correctly after loading the city. (reported by Omnius)
Industrial buildings were not spawning on the highest valued land as intended and could also spawn on residential lots. (reported by raxo8888)
Stage 2 middle and upper class buildings had the same amount of occupants than at stage 1.
The maximum stage of buildings could be exceeded for lots built with the custom density tool. (Reported by KenanYK)
Houses now have color variations (only Stage 1 for now).
Increased distance at which pedestrians are visible.
Changes to the details distance setting was still not taking effect immediately.
Improved camera behavior when close to the ground and changed starting position.
Added a fix for missing textures on buildings (replaces pink textures by green bricks if bugged).
Added a frame to the city map.
Added water sound effect.
Changed the highway building icon to be more distinctive.
Tutorial was not detecting a completed step in pause.
Trees are again properly set transparent when zoning or building roads.
Vehicles around service buildings are now merged in chunks like they are for RCI buildings. Reduces CPU usage and makes sure all vehicles are saved and reloaded correctly. (Services built before the update will not display any cars.)
Trees, grass and props were sometimes not automatically updated after a building changed or got destroyed.
Alert messages are not displayed while in pause anymore.
When hiding the UI with key "V" the layer icon is now hid, clicking the option icon unhides the UI.
Fixed a bug that was affecting the mouse interaction with the list of saved nation in the "Load Nation" panel.
The government etiquette "Dystopia" was not displayed when applicable.
Added red line at the bottom of the interface when the game is paused.
Added hotkey to switch simulation speed (backspace).
Changed buttons in Nation view.
Optimized the way roads are displayed in Nation view (reduced CPU usage).
The service building editor panel was sometimes displayed partly offscreen. And, has been lightly redesigned to match with the new query tool.
Added cpu and gpu icons in the graphic settings to highlight the options that affect the most the performance.
Fixed a misplaced arrow in the tutorial and fixed "STATS" tooltip (reported by phyziyx).
What's next
Update 1.4.0 will come out in another 4 weeks and should bring a couple of fun and unexpected features. Stay tune!

Decreased the effect of the exchange rate on the trade balance.
Changed the cost of buying and selling dollars and doubled the maximum reserves limit to 1.95M.
Increased default religiousness level by 0.2pt. (suggested by Omnius)
Increased the effect of education on the unemployment rate (in general: more education => more unemployment).
Capped the maximum amount of jobs that can be shared between cities to 50,000.
Gulags capacity multiplied by 4 (and profits by 2), Rehab capacity x2, Prisons capacity x2. Have to be rebuilt to take effect.
Made floating alert icons more visible. (suggested by GeneMonty)
Bug Fixes

Amount of printed money was not saved. (reported by Jacob)
Park paths built on beaches were not taken into account for the quality of life. Increased land value bonus from park paths.
The incarceration rate displayed in stats was wrong (visual only). (reported by Neurolefty)
All ploppable buildings could in some cases connect to rail tracks or highways. This could either make it impossible to place the building or it would built it but close it down immediately. (reported by Omnius)
Smoothen coastline (requested by U.S.Eagle).
Improved tree LODs order of rendering.

The new pathfinding algorithm was causing lags and crashes in cities with complex road networks. Holes between roads or incomplete networks were causing "Can't reach workplace". The AI can now U-turn when the road ahead is missing. The 2048 tiles commute length limit was not taken into account, leading to infinite commute length and crash to desktop.
Improved performance. Smarter distribution of heavy tasks (heatmap layers update, traffic update, terrain update) across frames. Optimized car and pedestrian AI. Optimized heatmap computation.
Park paths could never be destroyed when a road intersection were built next to it (reported by Livonia).
Reduce lag when building highway access roads.
Fixed blinking issues on textures (reactivated mipmaps on the occlusion layer of the materials).
Balanced the propagation of pollution, spread of polluted areas was asymmetric.
Residential buildings were never getting abandoned if they didn't find a path to their workplace.
Unemployment calculation was wrong if a connected neighbor city had a negative amount of job to share.
Businesses and vacant lots could have a security score above 100. (reported by El Dictator)
Position of the difficulty stars was incorrect with some screen resolutions.
Corrected text 'Slum Growth' in population stats to 'Slum Demand'. (The slums' growth is the value between brackets.)
Increased effect of inflation rate on the social ladder (+33%).
Loading a city created before 1.2.0b will results in strange waves of pollution moving across the map which can cause temporary abandonment. The new pollution algorithm needs time to readjust.

Major fixes

Fixed a major error affecting the number of jobs created by the upper class (was 10x the intended value). A lack of workforce was probably affecting your city as soon as the upper class grew.
Social class distribution % values were incorrect. Could lead to a negative incarceration rate. (Reported by Omnius, thank you!)
The effect of policies on political affiliations was incorrect when the policies were mostly left leaning. (Reported by BiOxYdE, merci!)
Effect of policies on pollution was incorrect! Eco-friendly policies now have greater effect on reducing pollution. Thanks to Alex Vagni for reporting this discrepancy!
New algorithm for the propagation of pollution. Polluted areas were taking too long to clean up if pollution ceased. Pollution might get all over the place after loading your city for the first time with the patch, it'll take a few in game years to stabilize.
Balanced the environment score (used for quality of life index and approval rate). Was wrong in polluted cities.
Connected cities will now share jobs across borders when the unemployment is lower than 10%. Unemployment is no longer exported to connected cities, only jobs. Up to 10% of all jobs can be imported from a connected city. When the unemployment is too low, jobs from connected cities will no longer be available to dampen the lack of workforce.
When upgrading a service building the employee current funding ratio is now preserved.
The dollar reserve was not being saved when exiting the Nation or the game.
Improved pathfinding significantly. Highways are used more often. Commutes can now be up to 2048 road tile long (640 before).
Other changes

Added some extra safeties to prevent the education score to go brrrr.
If you had more than 1 million USD reserve the exchange rate could equal to zero.
Doubled the area affected by the carbon capture buildings.
Census tool now shows pollution rate on roads, rails and walkways.
Changed the color of the pollution layer to be more visible.
Increased prevalence of rare ore and offshore oil.
Census tool was displaying "Insufficient Demand" for vacant lots even when the demand was high.
Shorten display of trade capacity in Nation UI.
Improved port placement tool. Have to be rotated manually like airports by pressing TAB.
Census tool did not give any information for farming tiles.
Increased religion effect on birth rates
Population growth from neighbor cities was not taken into account.
Slums now participate to the Lower Class natural growth rate (births).
Removed "Too Steep" limitation to road building.
Removed "Unaligned Intersection" limitation to road building.
Updated PT-BR localization
The demand for slums would never decrease when many low income citizens were getting richer.
Corrected tooltip for the trade capacity in Nation view.
Lack of workforce triggers building decay more often.
Changed how commuters pick a workplace. Generally choose location closer to their home.
Residential buildings under construction no longer loose their occupants during construction (the city's population stays unchanged). (suggested by raxo8888)
Government type "Utopia" was not being displayed in the top UI (also reported by raxo8888)
Volumetric clouds in city view are now turned on by default for the preset 'High'.
Much appreciation for everyone that took the time to email me suggestions and bug reports!

Update 1.2.0 - Mining, Harbor, Trade Balance

New

Added underground resources, 4 types: Oil, Gas, Common Ore and Rare Ore. Resources first need to be looked for using the prospecting tool (under the industry buildings tab). Depending on the ore available underground we can then place a mining lot which will instantly build 1 of the 5 mining buildings (an oil field, a gas field, an open pit mine, an underground mine and an offshore rig). Mines and rigs provide jobs, tax income and improve the trade balance.

Added a container port and container ships. Ports increase the value of a city's exports. The trading capacity of ports is shared accross all cities (like power production).

Added trade balance, takes into account the exchange rate, the trade capacity (from ports and airports) and of course the imports/exports ratio. The trade balance is NOT shared accross cities. The census tool will show the exports/imports balance for each commercial and industrial lot.
Added alert icons over buildings. Will display one of the 8 most common problems: no water, no power, not enough demand, unemployment, no workforce, pollution, crime or 'can't reach workplace'.
Added 3 farming variants
Balancing and Changes

New job creation / distribution algorithm to stabilize the economic cycles and facilitate economic transitions. (I really thought we were done with big economic changes but I discovered that some of the adjustments made previously were actually disregarded entirely once the game was initialized).
New inflation and exchange rate system. A bit more complex but theoretically more realistic. Updated the economy stats panel.
Enhanced spatial segregation of social classes (sorts lots based on their land value and picks the most relevant).
Added the option to sell dollars.
Added a dynamic representation of political affiliations in the approval stats.
We can now reduce the tax rates and print money even if stability is at zero.
Minor Fixes and Changes

Replaced display of the exchange rate by the trade capacity (earned from ports and airports) in Nation UI.
Improved Census Tool and Service Editor position. (solution proposed by GeneMonty, thanks!)
A Stage 7 upper class building had a concrete texture instead of windows.
Pressing escape while destroying a zone now cancels the action.
Added tooltip displaying the reason why a building can't be placed (if no road access or insufficient funds or terrain too steep).
Terraforming actions are now prevented when the balance is insufficient.
Some residential sound effects were not being used.
Lowered the quality score threshold for service buildings to reach grade A (visual only).
The population amount coming from neighbor cities is now displayed in the population stats.
Increased inflation effect on the social ladder.
Decreased incarceration rate (-20%).
Decreased number of students in high school and elementary (-20%).
Decreased traffic (-15%) and pollution (-25%).
Decreased land value requirement for advanced manufacturing (-25%).
All menus can now be closed with the ESC key.
In large cities new low class houses could sometimes never develop.
New attempt at solving the ever disappearing airport stage 1.
The red district was not keeping its initial rotation after loading back the city.
Improved boat navigation. Should not sail on land anymore.
Gained about 5 seconds on saving and loading Nation.
Riots have a larger area of potential destruction.
New residential buildings no longer start with an education score of zero, depending of the social class they will start with up to half of the current city's education score.
News about prison overcrowding was triggered at 80% prison occupation.
Known Issues:

Placing the port can be difficult in small spaces. A large open shore is recommended. Build a road first.
Helipad cannot be destroyed.
Cars on service buildings disappear after reloading the city.
Localizations other than English and French related to the new features are of mediocre quality (will be updated in June).
Props and trees can clip into buildings for a while before getting updated.
Update 1.2.1 will add new lot sizes, possibly an option for larger maps, big changes to the bottom part of the UI, a revamped census tool, and new unique buildings. It'll take about 4 weeks of work.

Patch 1.1.4b

A couple of important bug fixes and other changes that could not wait for update 1.1.5 to be published. Air Taxis were sometimes not showing up and a memory leak has been finally solved.
NEW

- Bus and train stops can now turn a profit if enough commuters are using the service.
- Abandoned buildings are now painted in red in the land use layer.
CHANGES

- Faster update of commute paths (x6). This should help citizens change mode of transport if a new one is made available.
- Faster business demand evolution when points are added (x1.5), slower when points are subtracted (x0.75)
- Faster spawn of new business buildings (x3 in large cities). Abandoned buildings can be rebuilt in less time.
- Faster stability regeneration when no government buildings exist.
- When a business is abandoned or destroyed 50% of the demand is now recovered (prevents fast unemployment spike)
- Changed computation of the inequality index. Fixed approval rate from inequalities going over 100%.
- Changed slum growth value in stats. Now displayed total current informal demand and correct demand change.
BUG FIXES

- Fixed a serious memory leak that was affecting the game since release. Up to 3GB of ram were getting eaten in large cities. This problem was mitigated until now by a manual unloading of unnecessary data every 4 in-game years, hence the slight freeze happening regularly. I'm keeping this unloading event for now but set it to repeat every 10 years, just to be on the safe side.
- Air Taxis were not showing up if the amount of active vehicles was maxed out or if commute paths were not updated. They also might be difficulty to spot, pan down the camera as so to see the horizon and you should see them. Remember that only upper class citizens can use air taxis.
- Fixed errors with the pathfinding algorithm. Reduced total traffic by about 20%.
- Range of bus and train stops was erroneous. Expect higher public transport usage. (With access to both bus and train, 15% of the population will still prefer to walk or use the car.)
- Removed the effect of demand on inflation. Will be replaced by the trade balance (coming up with version 1.1.5)
- Starting Nation Treasury will now be identical to a new city's balance, matching the difficulty level.
- Rocks were disappearing and sometimes appearing above ground in one of the map's corner.
- Corrected job distribution graph in stats.
- Nation loading crash handler: shorter wait time in case of corrupted data before forcing open the Nation view.
- New attempt at fixing the ever disappearing stage 1 airport.
- Clamped to 100% the immigration bonus from airport connections.
- Difficulty level would default to easy if buttons were never interacted with.
Update 1.1.5 should come out in 2 to 3 weeks.

NEW
- New Biomes: Arid and Temperate. Your Nation will now have different climates ranging from the North to the South with vegetation and terrain color progressively changing depending on altitude and latitude.
Closer to the North you'll find the temperate climate with spruces and yellow oak trees. In the center at lower altitude you'll find the sub tropical climate (the default existing biome).
To the South, a more arid, desert like biome with palm trees and cactuses. In total 6 new trees have been added.
Different types of trees are now assign to lots depending on their level of wealth. Trees on road sides are not affected by climate.
- New difficulty settings. The old options have been entirely replaced with new presets so that the easy mode is actually easy. 3 options:
* Easy: This is a difficulty level that could be considerate in par with today's other management games.
Starting Balance $100,000; Tax Income +30%; Approval +20pt.; Unemployment Stabilizer ON; Pollution Low; Abandonment Very Low; Birth Rate +0.3pt; Immigration +0%; Treasury +0%
** Normal: Recommended if you still haven't got your phD in economics.
Starting Balance $50,000; Tax Income +15%; Approval +5pt.; Unemployment Stabilizer ON; Pollution Normal; Abandonment Low; Birth Rate +0.1pt; Immigration +10%; Treasury +10%
*** Realistic: Slightly more difficult than the previous version. Existing Nations will automatically be set to this difficulty level. (To change it manually for existing Nations see details at the end.)
Starting Balance $20,000; Tax Income +0%; Approval +0pt.; Unemployment Stabilizer OFF; Pollution Normal; Abandonment Normal; Birth Rate +0.0pt; Immigration +20%; Treasury +25%
1, 2 or 3 stars will be displayed in the main UI depending on the level you chose.
- Air Taxi Station: Once researched and built, allows the upper class to use flying cars to commute. Reduces traffic congestion (in rich cities). This is the last special building to unlock in the research panel.
- Added a New Sports Car, a Pickup Truck and changed the bus model.
- Added 19 new city sound effects (total of 131 ambient effects) and improved audio management and mastering.
- Added 3 new materials and changed some buildings textures.
CHANGES
ECONOMY

Increased minimum and maximum limits of the demands (the UI bars have the same maximum bounds but the values themselves can exceed their representation; the minimums have been changed both visually and in the data)
When a residential building is now abandoned or destroyed: 70% of the inhabitants are added to the demand of the class below, 20% are added back to the same class demand and 10% leave the city. When a slum despawns, 100% of the occupants are added to the lower class demand. The city's population will no longer collapse!
When a residential building was upgraded, the total amount of occupants were removed from the demand. Now, only the amount of additional occupants is removed from the demand.
Changes to the population growth system derived from social mobility. Corrections to the demands algorithms (new population could be created outside of births and migration).
A part of the demand was wrongly destroyed when a residential building was replaced by a different class type therefore distorting the social ladder system. Social mobility dynamics now operate in a closed circuit, theoretically.
Houses stage 1 can now also be replaced by another class if the demands are unequal.
An office lot can be replaced by retail and AM can be replaced by BM (Only the opposite was possible before). Conversions also happen faster.
Various other changes to the demand system for industrial and commercial businesses to prevent overinvestment phenomenon (a new construction could create unwanted demand for other sectors which would be rectified later on and lead to abandonment). The economic system is now more stable and more precise.
TRAFFIC

Traffic data collection was erroneous. Ambulances, fire trucks and pedestrians were adding up to the congestion. Traffic from commercial buildings were not taken into account. Buses had too much impact on congestion. Increased the distance a citizen is willing to walk from 16 tiles to 19.
New color gradient for the traffic layer. (green = not congested, red = 100% congested, purple = 200% congested)
If a citizen has access to both a train station and a bus stop: 70% chance of using the train. 20% chance of using the bus. 10% chance of using his car.
Roads with trees can no longer absorb all pollution emitted by traffic.
Increased maximum commute distance to 640 road tiles. I recommend avoiding segregating jobs and homes or building any weird road networks that would force long commutes which will still lead to "Can't reach workplace" abandonment issues.
Bus stops and train stations now increase nearby land value.
You can now build bus stops and stations on roads with trees.
BUG FIXES

Added a fix to infinite loading screen when launching the game.
Graphic settings were still not loaded correctly in city view and details distance settings were not applied immediately.
Upper class buildings were never decaying when the demand was at its minimum negative limit.
Parking lots were almost never replaced by new buildings even with positive demand.
Vehicles were not spawning in night mode.
Red light district economic freedom requirement shown in research menu was wrong.
High Rises could not catch fire (either from Riots or low security level).
High Rises being turned into parking lots will now decrease the stability score.
All occupants of residential high rises turning into parking lots were leaving the city and none were added back to the demand.
Residential UI demand bars pop up numbers were not displaying bounded values (happened in large cities).
Corrected Arcology C requirement in Research Panel.
The National Treasury bonus was incorrectly computed.
Policy requirement to unlock government HQ stage 5 was erroneous.
Jobs in arcologies were not being taken into account for the GDP computation.
The state social media building were not affecting the Nation as advertised. Once built you can now expect: +10 approval bonus points, -2 education quality, +2 security level.
The StateCopter was visible hanging under the map.
National Treasury can no longer exceed 1 billion (this value was getting negative when exceeding 2.1 billion (integer overflow)).
Ploppable buildings could be placed along rail tracks.
Census tool was not showing the lot type of parking lots and abandoned buildings.
Government buildings will no longer close if their road access is lost.
Max Stage of government buildings were incorrect in the census tool.
Removed requirement of Government HQ to unlock the immigration office.
In custom policies list, the cost were shown in grey instead of red or green.
Texture Optimizations. 500+Mb of ram saved.
