Graphics

Improved map colors by adding specific colors to beacons, pipes, heat pipes, roboports and steam engines.

Sounds

New or updated sound effects include:
Pump, pumpjack, boiler, heat pipe, offshore pump, substation.
Logistic and construction robots, roboport.
Train.
Rocket takeoff sequence.
Car and tank (pitch scaling adjusted to sound more natural).
All transport belts, splitters, inserters, assembling machines, power switch.
Added some UI sounds that were missing.
Shotgun, small explosions.
Entity destroyed alert.
New sound tech includes:
Listener position set to centre of screen by default. This will allow you to hear what you see even when in map mode.
The ability to turn off the Doppler effect in Lua, used for the Substation so far.
environment-audible-distance setting increased to 30 so you can hear entities a bit further away.
zoom-volume-coefficient changed so you can hear more of the world when you zoom out. This will help with combat and give a greater sense of the overall factory.

Fixed that pressing escape in some log-in screens lead to blank screen or incorrect states. more
Fixed enemy walls should not render as connected to ghosts, since enemy ghosts are not visible. more
Fixed undo on self-looped combinator ghosts not restoring wires. more
Fixed achievement cards not showing description when descriptions are turned off in interface settings.
Fixed that inserters from 0.17 save files could end up teleporting items into/from trains. more
Fixed that the sync mods with save GUI wouldn't size correctly. more
Fixed that thrown capsules could end up broken forever if thrown at exactly the right tick. more
Fixed crash when using "create-entity" trigger effect item to create an artillery flare. more
Fixed map view night LUT. more
Fixed a crash that would sometimes happen when a biter, who was in previous versions of the game aggroed by a player in a car or tank, was aggroed again. more
Fixed crash when joining a game through Steam without having previously logged in.

Migrating loaders between loader and loader-1x1 will maintain the loader type (input/output). more
