I have updated the mod to v8 with the following changes.
Sadly at this stage the mod is unlikely to receive more updates considering civ6 is around the corner. The interest for the mod by users also has decreased since the anouncement.
I'm quite happy where it's at even though not everything was fixed in my opinion.
I plan to mod civ6 instead. Civ6 is very likely to release with balance issues from what I see but on the other hand the features of the game look really interesting with a lot of gameplay options. I think we'll have to wait a bit for the modding tools though.
If civ6 is trash and I end up returning to civ5 then I may continue working further.
