July: loads of bugfixes, map geometry improvements, UI cleanups,
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
September: full support for driving on the left, textured color scheme,
rendering isometric buildings, editing traffic signal offsets, a big round of
UI changes, infinite parking mode, trip purpose, alleyways
October: unit tested turn generation, web version launched with async file
loading, thought bubbles showing agent goals, slow parts of a trip
highlighted, more UI overhauls, dedicated OSM viewer mode started, major
simulation performance optimizations, major progress towards live map edits,
automatically picking boundaries for arbitrary cities
November: switched from Dropbox to S3, download new maps in-game, collision
dataviz UI, day/night color switching, unit testing lane changing behavior,
starting the 15 min walkshed tool, simplified simulation spawning code,
recording and replaying traffic around a few intersections, refactoring to
split out separate tools
December: lane-changing fixes, blocked-by explorer in debug mode, non-Latin
font support on web, saving player state on web, census-based scenario
generation started, 15 minute Santa
January: experimented with SUMO import, UI button overhaul, day/night mode,
first separate cycleways
February: better web loading and URL sharing, randomized parking, procedurally
generated houses, actdev integration, geofabrik picker, new day theme, static
routing penalties
March: UK flow-based scenario generation, roundabout gridlock fixes, UI panel
redesign, one-step OSM importer with UI, elevation data & layers
April: pathfinding by roads, editing number of lanes, risk exposure, Tempe
intersection consolidation
May: GMNS signal timing import, cloud map importer, OSM turn lane fixes
June: performance, first dynamic vehicle lane-changing, exiting driveways
off-sides and across multiple lanes
July: pathfinding refactor, Broadmoor blog post, mode shift tool, massive
intersection consolidation breakthrough, deduplicating cycleways in OSM, bike
lane separators, new day mode colors
