So, I wonder, did anyone here, especially those who have not reverse-engineered the code yet, actually understand what the first three changes mean in practical terms?

I certainly know all/most of the terms used but I can't really say what effect exactly these changes will have, at first it seemed to me like that was done intentionally, people wanted technicalities so they got some that they cannot really understand anyway, if so, I really liked the joke.
If everybody else does know what exactly they do, then I guess I'm the clown of this thread now.
