access-restricted zones for private neighborhoods and no-through-traffic,
better traffic generation between home<->work for new maps, complete overhaul
to bus routes and introduction of light rail, commute pattern explorer,
importing Krakow and Berlin, smarter lane-changing, walkable shoulders for
roads without sidewalks
August: Michael joins, multiple traffic signals can be edited together,
started a headless JSON API, support for other languages in OSM data, started
congestion capping, backwards-compatible and more robust map edits, two-way
cycletracks, more cities imported, slurry of bugfixes and performance
improvements
