I was able to caught 2 link errors with this check in release notes.

I am not sure if we really want to leave broken link in the release notes tho.

Thanks.

We can revisit this again but as of now it is blocking the development in terms of PR merge. We can either run the check in local using lychee or use label to run for a specific file in the future.

Seeing the same issue here. #4615

I'm ok we disable it for release notes for now. Could you maybe create an issue so that we could keep track of this in the future?

Release notes do always have a failing link especially the prod website links that only go live after release is done. Will create an issue to either run based on label or create another workflow to only run against that specific release notes.md file rather than entire folder.
