Add a Changelog (best named 'Changes') to the distribution. It should list at least major changes implemented in newer versions.
Add a META.yml to the distribution. Your buildtool should be able to autogenerate it.
Remove the POD errors. You can check for POD errors automatically by including Test::Pod to your test suite.

Split the distribution, or fix the version numbers to make them consistent (use the highest version number to avoid version downgrade).
Add =head1 LICENSE and/or the proper text of the well-known license to the main module in your code.
Add a META.json to the distribution. Your buildtool should be able to autogenerate it.
Define the license if you are using in Build.PL. If you are using MakeMaker (Makefile.PL) you should upgrade to ExtUtils::MakeMaker version 6.31.
This is not a critical issue. Currently mainly informative for the CPANTS authors. It might be removed later.
