I'll look for it but might take some time since OF search function is absolutely terrible and is completely hit or miss if it will actually come up with all the things within the search.
edit: Hmmm ok so here's the 2 updates that effected evasion

update said:
The evasion of high-level monsters has been decreased
Which is super vague in all kinds of ways (wouldn't even know it's what we were talking about from that lol) but they did talk about it a
dev note which came from the reddit
AMA right before that update.
Dev said:
Adjustments to monster evasion
We’ll be lowering the evasion values for high-level monsters. The higher the monster’s level, the more we will be reducing their evasion.
AMA said:
In the August Version Update, we’ll be making changes where it will lessen the amount of evasion that high-level monsters receive from AGI. Due to that, the amount of accuracy required will decrease. We would like to see how this change affects the situation and proceed from there.
Both of which aren't exactly clear. Guess probably is all for the agi thing just based on an amount that somehow high level got thrown in because official translations are the worst
