Check out https://github.com/perl5-dbi/dbi/commit/d6e2bf13ac6043f5b0a9a147805b4915bd70e631

We are working very hard to get DBI back in shape after 4½ years of relative silence.
Changes have been committed to git, but a release did not happen

If you depend on a recent DBI, check out from git.
As releasing is a long process to make sure we did not break new
things, I am not doing releases in haste
