They did. They said they would be doing backbone work for Shadowbringers. Said on the post on the website as well as the post when you log into the game.

Can confirm. PC, was in game for the past hour-ish.
I mean, all you have to do is log in on the launcher and the Play button comes up. It's literally that easy to check.
Your reading of the post is different then mine. It appears to be the standard notice for a game patch. While there is no mention of Shadowbringers I suspect you are right in that regard. They should have just said that instead of adding a misleading patch number when the MINOR adjustment could have mentioned in the maintenance recap. People were expecting final nerfs to Pyros Light and possibly Hydatos. People know prep needs to be done for a new expansion so just tell them and they will accept it.
I went back to check the whole stress test thing. But it apparently started and ended without me even noticing.
You mean the Alphascape Crystalloid? Yes, you can look it up in the Patch 4.57 Note:
"The weekly restriction on the number of Alphascape crystalloids available as completion rewards in Alphascape V4.0 has been removed."
Game not available yet! They are unusually late this time and they didn’t even announce about it! What is going on?!
Edit to add, I’m on ps4.
