Release notes here!
One resounding theme of recent UI feedback is “the upward-expanding pile of buttons at the bottom has got to go”. So for this release we told all the functions in that menu “you ain’t gotta go home, but you can’t stay here”.
The result is a general layout of:
1) Passive info on the top half of the screen
2) Interactable controls on the bottom half
3) Stuff pertaining to your selected units (if any) on the left
4) Stuff pertaining to your selected planet on the right
There was also a major switch in the graphics pipeline (now using Alloy since it recently became open-source and we could thus let modders have access to it) and a move of a ton of visualization code into the external-visualization project, which greatly expands what modders can impact.
