Graphics

• Added player footprints and footstep visual effects.
• Added car and tank dust and particle trail visual effects.

Changes

• Construction robots throw cliff explosives from afar the same as players do, instead of dropping them at the cliff.
• Changed rail segment visualisation colors to be more different from rail signal colors (red/green).
• Clicking a GUI now brings it to the front. Most noticeable when using the map editor or debug GUIs where they overlap.

Bugfixes

• Fixed that Fast splitters were missing a piece visually in East rotation top_patch more
• Fixed that inserters could insert modules for recipes into module slots in some rare cases. more
• Fixed that robots blowing up cliffs was different than manually blowing up cliffs. more
• Fixed limiting cargo wagon to 0 slots would break progress visualization for full cargo and empty cargo train conditions. more
• Fixed teleporting player between surfaces while the player was in a map view would not invalidate tile renderer cache. more
• Fixed that the "use different settings per save" setting didn't work for single player games. more
• Fixed crash due to use-after-delete when single unit builds a base in position that does not collide with the unit. more

Modding

• Added the Prototypes GUI (ctrl + shift + E).
• Added the Prototype Explorer GUI (mouse over most anything + ctrl + shift + F).
• Added support to play different sounds for entity ghosts depending on the size of the entity in the ghost through build_sound (for small), medium_build_sound and large_build_sound on the entity ghost prototype.
• Added support to play a sound when switching weapons defined through utility-sounds 'switch_gun'.
• Added support to play a sound when picking up items (F key) through utility-sounds 'picked_up_item'.
• Added optional 'turn_speed' to projectile prototypes.

Scripting

• Added "include_fuel" field to LuaItemStack::create_blueprint.
• Changed LuaSurface::create_entity so it places resource entities to center of a tile as map generator would. This can be overridden by optional snap_to_tile_center parameter. more
