  1. Increased multiplayer support from a maximum of 8 players to a maximum of 16 players.

  2. Added new items: Iron Armor and Iron Leggings, providing high-level protection.

  3. Fixed an issue where parts of a structure would go missing upon reloading the game if the player exited immediately after building a train.

  6. Increased the resource drop rate for Alloy Pickaxes and Alloy Axes, upgrading the bonus from double resources to triple resources.

  7. Added a new mechanic: If a character's Food and Hydration levels exceed 150, they will slowly regenerate health at the same rate as when sitting on a chair.

  8. Optimized the UI background width for the "Cannot Join Room" notification on the main menu to prevent text overflow. Fixed UI alignment issues on both the main menu and within the game—caused by varying monitor resolutions—that previously rendered UI elements unclickable. Enabled higher UI rendering precision settings to ensure the interface appears sharper and more visually appealing.

  9. Fixed an issue where animals within an animal pen would only breed if their Food and Mood levels were exceptionally high.

  10. Reduced the likelihood of the game becoming unresponsive (freezing) when clicking the "Exit" button.

  13. Increased the drop rate for Gold Ore, making gold deposits a less rare find.

  14. Significantly increased the drop rate for leaves when chopping down trees.

  15. Implemented a "disappearance protection" system for dropped item bundles; bundles left aboard a train will no longer be automatically destroyed.

  16. Significantly reduced the amount of health lost when consuming Raw Chili Peppers.

  17. Removed the health-deduction penalty associated with eating Roasted Chili Peppers; they now have no negative side effects.

  18. Revised the item descriptions for "Insecticide" and "Earthworms" to eliminate potential ambiguities.

  19. Updated the visual design of the sliders within the "Construction" menu, giving them a more polished look and eliminating their previous "cheap" aesthetic.
