Planets are now visible in the background of space platforms.
background visibilityRockets can now carry multiple different items in one launch.
cargo capacityNew graphics were added for assembling machines, oil refineries, rocket silos, and heat exchangers.
graphicPlatforms can now request items from and provide items to other platforms in orbit.
item transfer capabilityA special cargo bay was added that inserters can take items out of to unload the landing pad directly into other structures.
unloading bayA diagonal flamethrower turret graphic was added.
orientation graphicA new pump rendering system was added that can connect to fluid wagons regardless of station layout.

Biters now choose more natural locations to build new bases.
base location selectionFluid mixing prevention has returned so pipelines with different fluids will not merge and instead give a warning.
fluid mixing behaviorFluid flow now scales properly with high throughput.
