I, too, would like to know what it contains.
As you mentioned, there is one page for a single Verizon V60 update on their site (and it's a couple months old).
Is that a serious reply? I haven't read anything about Verizon and LG adding this nor documentation.

Update: I was Googling wrong... This is likely the contact tracing API update mentioned here.
I was looking for something from LG or Verizon, not a general Android update from Google.
Still, some documentation would be nice. My understanding is it simply allows apps to now do contact tracing, and it's not something your phone will now do natively.
I understand and recognize the possible value for this, but Holy crap... this is such a potential privacy hole.
