Roadmap

City depth

Release 0.15, October 7, 2026

The city filled out with water, trees, parked cars and new kinds of building, and stayed fast at a larger size.

Done when

The city grows larger and fuller, with water, trees, parked cars and new building types, and large cities stay within the frame budget.

Hills and graded streets moved to a later milestone so this release stayed short. Release 0.15 covers what shipped.
