Knowledge Update 2020-08-20

Hi!
Welcome to the first of many (I hope) knowledge updates from me. My goal is so gather information in one post instead of many posts.
Most of this information are from third party and I do not have the time to source review everything. But still I like of sharing my thoughts to you.
This first knowledge update will be in compressed format only to see if there are any demand for this at all. But the headings I like to keep the same always.
Please feel free to contact me if you have any suggestions or comments.
