Password problem with ubuntu first login

Where to release notes live? I don’t see any at Index of /ci/ubuntu/22.04/ (or parent directories.

For 22.04.1 I found https://hub.libre.computer/t/ubuntu-22-04-1-jammy-lts-for-libre-computer-boards which links to release notes for base, desktop, and server. Like https://hub.libre.computer/t/ubuntu-22-04-lts-server-release-notes/ which contains passwords.

When I pulled down 22.10 I could not find any release notes and the password is not the same as 22.04.1 (I got lucky with the root password though), where do all the release notes live?

Thanks!
