Several crashes are fixed, including ones that could happen during startup, in late-game enemy turns, when closing the Ship Designer, and during turn rollover or autosave around the shipyard.
Ship hull mass capacities have been raised across every hull size. Alongside that, the AI no longer designs ships that go into battle without weapons, so opponents field fleets that actually fight back.
Pollution now scales more predictably on high-level worlds, so runaway pollution is no longer a problem. Mining starbases behave correctly when built near a contested resource, and a few planetary improvements have been tuned.
Ceasefire negotiations carry more weight now, both when you accept one and when you pay a rival for it.
The debug console has its own hotkeys that no longer overlap with the base game, with dedicated keys for teleporting, cloning, resetting moves, and deleting a selected object.
The new planet and resource context windows and the Adaptive AI settings are now translated in all supported languages.
