mysql 8.0.29 being used for "max" but it can't even be downloaded anymore because it has a bad bug
It came up in another context that 8.0.29 is what's being used, but see https://dev.mysql.com/doc/relnotes/mysql/8.0/en/news-8-0-29.html
This release is no longer available for download. It was removed due to a critical issue that could cause data in InnoDB tables having added columns to be interpreted incorrectly. Please upgrade to MySQL 8.0.30 instead.
I don't know if the version in use is from a particular distribution that backports patches so maybe is not affected, but also the latest is 8.0.35.
