Q:

How can I list the changes that have been made in an apt repository (server side)

I know from an apt update && apt list --upgradable, that there is an upgrade available for a specific package. 
Now I am interested in the exact timestamp when that upgrade has been published in the repository. 
To be specific, the package in question is openmediavault from http://packages.openmediavault.org/public/ erasmus/main amd64 Packages 
As I am writing this question, the version in the repo is 3.0.92 and the server-side change from 3.0.91 to the newer version most likely happened during the last 24 hours. But when exactly?
My system is Debian 8 "Jessie"
Thanks in advance

A:

You won’t get a list of changes over the whole repository, but you can view the timestamps of files on the server: add pool to the main URL, and explore from there. The openmediavault files are here; you’ll see the timestamps there. 3.0.92 is dated November 18 at 10:44 (in the server’s timezone).
