Fences now connect automatically — build a straight run or turn a corner and the posts line up and link together on their own, no rotating needed. Roofs now have a real shingle texture, and anything placed on a roof (like a chimney) sits right on the slope wherever you put it, instead of floating. Windows and doors now stretch to fill a wide gap automatically — drop one into a 2 or 3-block-wide opening between two walls and it fills the whole thing. Windows also got a more realistic look, with visible panes and a sill. New: Stairs, for building up to a second floor. New: Fill mode — turn it on and drag across the floor to lay a whole row of the selected piece at once, instead of tapping each spot. New playground pieces: Swing and Seesaw. Hold a piece still (without dragging it) to delete just that piece.

Roofs now fit your walls automatically — select a roof and tap the top of your house, and it stretches to cover it, any size. Windows and doors are now two blocks tall, so you build up around them like a real house. New brick and log textures make walls look like real building materials. Undo now always removes exactly the last piece you placed. Plus a few other small fixes and polish.
