registry.fedoraproject.org/fedora:39 rebuilding daily

Hello. I've noticed that currently fedora:39 docker/podman image is rebuilt every day. I understand that Fedora 40 is in beta and, likely, daily rebuilds of fedora:40 are intentional. But why is it happening with fedora:39? I use fedora:39 as a base for multiple things, and daily rebuilds of fedora:39 then cause daily rebuilds of my images - for seemingly no reason. Is it possible to stop rebuilding fedora:39 so frequently? If I'm not mistaken, when 39 was in beta, 38 didn't rebuild every day.
