Learning: In the submariner-io/submariner-website repository, release notes for upcoming (unreleased) versions on release branches (e.g., `release-notes-0.23`) intentionally omit the date from the version heading (e.g., `## v0.23.2` with no date). Dates are only added once the version is actually released. Do not flag a missing date as an issue for unreleased versions.

Learning: In submariner-io/submariner-website release notes, individual bullet-point fixes do not include inline PR references/hyperlinks in their text. The PR number referenced in the PR title/description is just the source for the fix, not something embedded in the release note content itself. Do not flag missing PR references in the release note text.
