Yep

so giga patch PLUS this aren't needed? what about realspace? are they all unneeded?

As of 2.8, this mod is no longer being updated. I have integrated it into gigastructure, where it will get further updates and features. All of the patches are also included within gigastructures. I will keep this version up for a while, so that you can wrap any old saves up if you wish to. Join gigastructures discord if you have any other questions please :)

What about the new worlds that have been added since then? Veld, Mud, Lake, Diamond worlds?

I've updated this to include that planets that were missed out from the base version of planetary diversity

I got hothouse I think, i'll add the others tho

Acordainly with the ehof_habitable_planets.txt file, I think you missed pc_hothouse pc_outback pc_highland and pc_wetswamp from the main mod. The last 3 ones were added recently, so some modders miss those ones when making compa patches. Thanks for the patch anyway!

I'll have a look into adding the sub mod ones, I think I got most/all of the main mod ones tho?

I think you might have forgotten to add support for some of the planet classes. Here is the complete list, if you want to take a look:
