I haven’t looked into it in detail, but
the CRs of the I5 helliquary bosses are different from the numbers in the update note.
What happened?
Is it always a lack of communication within your company?
As someone who played Diablo III for well over a decade, yes, they’re very well known for a lack of good communication, despite many, many posts over the years promising that they’d be better at it.
Basically, they stealth changed the patch notes a few hours prior to the patch being deployed and what we have in-game now matches the changed patch notes, not the original version of the patch notes.
You’ll notice that they didn’t bother to mention this in the thread where they announced the patch notes…
LMAO 
Great.
They got me.
They’ve had a history of doing like this few times before.
They have to communicate with Netease across the ocean, so communication may be more difficult.
I don’t think the Spectral Allies feature of random dungeon in the update note is there either.
I just checked it in the game…
Here’s another example from this morning’s patch.
This was in the Chinese patch notes…
They just didn’t bother to put this in the English patch notes at all.
I saw that too.
It’s clear that the Chinese patch notes are more informative.
But the Chinese translation is hard to understand because they have their own terminology.
They even missed the Monk balance nerf in the US patch note.
I think it’s worse to change things secretly than to be less informative.
The Monk Nerf was in the Bug Fixes:

So it was never intended to be this strong. It’s a shame though. Really liked melting Bosses with the stick. 
Thank you for your information
From now on, I will also look at bug fixes together.
