A major update has been made to Tanais Online, a game being developed by an individual. The latest version includes the addition of more cities, city populations, and various mechanics related to birth rate, death rate, and resource management. The game's population system is now controlled by these rates, which can be influenced by factors such as squalor and diseases. The player's gold income is also tied to their city's population.

The developer has also implemented a district-building feature, allowing players to construct various types of districts using resources. This feature is linked to the game's event system, ensuring a smooth gameplay experience.

To improve game performance, the developer has switched from saving data in a relation-based database to using JSON files. This change aims to simplify the process of saving and loading game states.
