It seems there is some logic to skip updates when image did not change, but it doesn't seem to work for me. Logs from download_file:

Either the modtime of the file was changed (or not correctly set) or caddy got a new scheme to calculate the etag.
Check modtime with stat -c %Y FILE

Caddy returns etag: "q6hc7a83andz", but locally I get qabj18c8z5s calculated, as you see in the logs.

Seems the size is also off!? size=20574208
