Monorail lines now follow hills smoothly instead of climbing in steps.
Drawing a monorail branch now previews the curve it will actually build.
New customisation: a paint tool with a colour picker (T), a customise button for machines, rockets and trains, and floors (concrete, blocks, tread) with brush sizes.
New floodlight with an aimable beam, and a taller Light Tower.
Every light now casts shadows.
Belts and monorails no longer go up slopes that are too steep; routes go around hills instead.
Construction drones fly over buildings instead of through them.
Cleaner lake cliffs (no more water creeping up the rock).
The game now runs on Vulkan for everyone, with an automatic fallback if it can't start.
Better performance on older graphics cards at the lowest ground detail.
Fewer stutters when the world loads, when new ore is found, and when the world map opens.
Many fixes to undo/redo for trains and stations, timetables, and pasted designs.
