I looked at all the changes that Factorio 2.0 will bring that could affect mods, here is the list to get an idea of how many there are (https://forums.factorio.com/115737). As you can see the list is long and I have identified 56 possible issues that might arise with Colony Builder when 2.0 hits. Then there is also changes to the tech tree and things like that.
This will probably take a while to fix, and I'll focus first on making the mod working with the base 2.0 game.
Ofcourse I'll also be busy playing Space Age as I imagine most of you are. Whether or not I will integrate the mod into Space Age I cannot say yet, I'll make that decision after I have played through it a few times.
