pkg.freebsd.org "hash_latest" repository introduction in FreeBSD:14:amd64

Hello list,

I always pkg-fetch(8) packages for upgrade, or new, from the "latest" 
repo into a local repository to NFS distribute them to multiple machines.

I've noticed a few days ago the fetched packages of FreeBSD:14:amd64 are 
stored in a automatically by pkg(8) (v 2.4.2) created new sub-directory 
named "Hashed" and the packages have, I suppose, considering the 
directory name they are saved into, a  hash tag in their names, e.g.:

New fetched files names:

vlc-3.0.21_20,4~7253d15082.pkg
x265-4.1~ebe69c23d8.pkg
xorg-server-21.1.20,1~fe5c37c403.pkg

Older versions file name: vlc-3.0.21_19,4.pkg

Local repository path after pkg-fetch(8) : 
/.../FreeBSD:14:amd64/latest/All/Hashed

Remote repository: https://pkg.freebsd.org/FreeBSD:14:amd64/hash_latest/

Remote repository configuration:


latest: {
   url: "pkg+http://pkg.FreeBSD.org/${ABI}/latest",
   mirror_type: "srv",
   signature_type: "fingerprints",
   fingerprints: "/usr/share/keys/pkg",
   enabled: yes
}


No other ABI (13, 15, 16) has the "hash_latest" remote repository 
(https://pkg.freebsd.org).

I tried to get information about this particular repo, but so far I had 
no success. Does anyone have any information about the "hash_latest" repo?

Best regards
