@perswardh: The release notes is published after the release is deployed on Sandbox environment. You can check release notes link which I will post under this article after release is on sandbox one day later, the releaser notes should be new release information. I send notification only when all stakeholders are confident the release is coming in the time range, release schedule is relying on many criterias, it might modify depends on different situations, so to avoid later changes, it is hard to post too early. I can try to send notification little earlier the coming releases if possible.
