As in title, what does this mod do? I didnt played Factorio Extended Plus-Machines so i don't know if it has bugs, should i use this mod?

from 0.16 to 0.17 there ware a couple of changes to the crafting speed of machines for example of the chemical plant and the centrifuge. I also changed the pollution of every machine because the Developers change the pollution System entirely

Thanks for feedback I will read to my description for the mod

Just asking, do I NEED this? cant stop thinking if I need it or not.

If you upgrade your oil processing in 0.17 without my mod your ratios would be broken
