What These Updates Cover

Each note is written to explain the player-facing result first, then the design or technical reason behind it. This keeps the update history useful for returning mayors, new players, and search crawlers reading the site without launching the game.

City Systems

Road access, utility coverage, zoning behavior, taxes, happiness, public services, and the rules that shape city growth.

Performance Work

Model loading, render cost, cache behavior, and mobile-friendly changes that keep the city playable on modest devices.

Player Guidance

Short explanations of how each change affects city planning, budgets, service placement, and early-game decisions.

Community Feedback

Comment threads collect bug reports, balance reactions, and requests so follow-up work can be tied to a specific version.

How To Read A BuildCity Patch Note

The update log is organized around practical questions a player would ask after returning to a saved city.

Check the gameplay impact

Look for changes to money flow, service coverage, roads, zoning, happiness, and city rank before changing a long-running layout.

Review stability notes

Performance, loading, cache, and save-state fixes are called out because they affect browser memory, network requests, and older devices.

Use comments for follow-up

If an update changes your city in an unexpected way, leave feedback on that version so the report includes the right context.

Version v1.4.20

Combined 48 facilities into one building reference with construction costs, hourly upkeep, footprints and in-game model previews. Existing individual links now open the matching comparison row.
Corrected the guides for water and sewage road connections, coastal placement, upkeep, offline income and deficits to match the actual rules. These are corrections to the guide text and figures, not changes to in-game costs or balance.
Linked trial buttons to the playable trial city and clarified that signed-in players are taken to their profile.
Improved comparison tables so they no longer overflow the page on mobile, and provided the new guidance in seven languages.
