Update changelog

[Morinohtar]

Hello @StephenGrider

I bought your Ethereum course and i'm liking it so far, congrats.

But there is one crucial thing that is missing, which happens to miss in all Udemy courses, and that is the update changelog. At least i cant find it anywhere and there are ppl also complaining about this.

I wanted to know what has been really updated so i can see what is the new content or the updated content.
The course says it was updated in June this year, 2021. So, what was really updated? The course starts in 2017, with solidity version 0.4 and currently is already in 0.8.6.

Can you please provide this, put that information available in the course?

Thanks.
