Nope, nothing. I don't understand it really. We don't even get changelogs. Every time an update gets released the forums fill up with "Why do I shoot/throw slower? Why am I getting error messages? Why is this killing me in one hit now? Why can't I wear armor anymore? Where did all my ammo go? Why did my accuracy get even worse? Do ants pee?" Actually, those are all the things I've been wondering since the last two patches. :/
No changelog explaining things. No official reasons posted anywhere. I was forced to retire and all I have to go on now is what is rumoured to be how the game works, and what I've been able to deduce of the changes myself through trial and error. Welp.
