There are a bunch of places on the website where patch/update notes could/should/might be but they are either empty or outdated or unrelated...at some point you should probably consolidate and delete some of this stuff and make ONE clear location for patch/update notes.

I'm not suggesting that this list is comprehensive, this is after about 10 minutes of searching. There may be more.
I never did find the "real" one...?

^ Obviously don't delete this one, but it is one of the many places I've been looking.

There's also the patch notes found on the launcher itself

The server is down (day #3), and this is the first time I've installed and tried to play, so I've never seen those.

That's good to know, thank you.

Regardless, once the game goes to full launch, they should clean this confusion up.
It's not a priority now in alpha [or even closed beta]... as long as they are available somewhere, I can deal.

Having all these different areas and something like this (for a pay game--again, not an alpha priority) is silly:

on discord (discord.gg/EvCW42) Ironsight he will upload patch notes when the patch is final. Not sure where the patch notes will go, but I'm sure it will be announced as well
