Simutrans is a free, open-source transportation simulator in which road, rail, air, and ship networks are built and managed.

According to the announcement, the last half year brought a flurry of activity, including AI-assisted (still carefully reviewed) bug fixing and extensions.

The last half year saw a flurry of activities, lately even profitted of AI-assisted (still carefully reviewed) bug fixing and extensions. New features are diagonal road signs and signals, making multple shared owners of stops without admin, new airplane state machine with much less deadlocks even on crossed runways, close diagonals, show a schedule as line in the map, prevent bridges through buildings, new waybuilder toll (F7 in pak64 and pak128) can build bridges and tunnels automatically, much faster loading of paks, faster iteration with many convois.

Key changes include diagonal road signs and signals, multiple shared stop owners without admin rights, a reworked airplane state machine with far fewer deadlocks on crossed runways, and an enhanced waybuilder tool (F7) that can build bridges and tunnels automatically. Pak loading is also faster, and iterating through many vehicle convoys runs more smoothly.
