First of all, SinkProb was added into the templates (in Decay, in both template_unit and template_structure).
Second, world_population_capacity was merged into population_capacity. This also means that settings.js in guy/common needs edited.
Third, backgrounds.js was added into the backgrounds folder, and needs to be added back in if anyone has a backgrounds.DELETED file. It also needs edited to fit their custom backgrounds.
Fourth, ProjectInformation and MainMenuItems have some changes regarding whether they use var g_blablabla to export const blablabla.
I'm sure there's more, but that's what I've found so far.
The Statue of Zeus at Olympia is one of the seven wonders of the ancient world, and as such it would be nice to have a model in the game for a potential capture the wonder mod.
I've found these CC0 models we could use:

https://sketchfab.com/3d-models/julius-casar-802edad501a94f9c99b84c4c33d376b7
Then put the head of Zeus on top of it, e.g. this one:

Someone else has done something similar with George Washingtons statue already:

We could use Nike from Athena Parthenos.
I'm won't find the time to do it soon, so I'm giving it out for anyone interested. I'm willing to help if anyone is interested in doing a retopology. I can then take it from there and bake a material. It's quite beginner-friendly as it requires mostly basic navigation in blender, but quite time-consuming. I propose using a tool like retopoflow for it.
