Add a META.yml to the distribution. Your buildtool should be able to autogenerate it.
Add a Changelog (best named 'Changes') to the distribution. It should list at least major changes implemented in newer versions.
Make sure that the main module name and version are the same of the distribution.
Add a META.json to the distribution. Your buildtool should be able to autogenerate it.
Add tests or move tests.pl to the t/ directory!
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.
Add 'use warnings' (or its equivalents) to all modules, or convince us that your favorite module is well-known enough and people can easily see the modules warn when something bad happens.
Error: NetPacket, NetPacket::ARP, NetPacket::Ethernet, NetPacket::ICMP, NetPacket::IGMP, NetPacket::IP, NetPacket::TCP, NetPacket::UDP
Ask the owner of the distribution (the one who released it first, or the one who is designated in x_authority) to give you a (co-)maintainer's permission.
Split the distribution, or fix the version numbers to make them consistent (use the highest version number to avoid version downgrade).
This is not a critical issue. Currently mainly informative for the CPANTS authors. It might be removed later.
