We've just released an update to the SHHS dataset. This release is based on the final Johns Hopkins BioLINCC dataset, however we've spent time to clean the dataset of impossible values, and created a list of known issues for variables with questionable values.
The full release notes are available on the SHHS Data Dictionary repository on GitHub.

Special thanks to @mcailler and @michellereid who created and closed over 955 issues in preparing this release for primetime!
