If you are using Build.PL define the {requires}{perl} = VERSION field. If you are using MakeMaker (Makefile.PL) you should upgrade ExtUtils::MakeMaker to 6.48 and use MIN_PERL_VERSION parameter. Perl::MinimumVersion can help you determine which version of Perl your module needs.

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!

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: App::RecordStream::Accumulator, App::RecordStream::Aggregator::Aggregation, App::RecordStream::Deaggregator, App::RecordStream::Deaggregator::Base, App::RecordStream::Operation::annotate, App::RecordStream::Operation::delta, App::RecordStream::Operation::flatten, App::RecordStream::Operation::fromcsv, App::RecordStream::Operation::frommultire, App::RecordStream::Operation::fromre, App::RecordStream::Operation::fromsplit, App::RecordStream::Operation::generate, App::RecordStream::Operation::grep, App::RecordStream::Operation::join, App::RecordStream::Operation::normalizetime, App::RecordStream::Operation::tocsv, App::RecordStream::Operation::toprettyprint, App::RecordStream::Operation::xform, App::RecordStream::Stream::Base, App::RecordStream::Stream::Printer

Add all modules contained in this distribution to the META.yml field 'provides'. Module::Build or Dist::Zilla::Plugin::MetaProvides do this automatically for you.

Add a 'repository' resource to the META.yml via 'meta_add' accessor (for Module::Build) or META_ADD parameter (for ExtUtils::MakeMaker).

Add SECURITY(.pod|md). See Software::Security::Policy.

Add SECURITY(.pod|md) and add a contact address. See Software::Security::Policy.

Add CONTRIBUTING(.pod|md). See https://docs.github.com/en/communities/setting-up-your-project-for-healthy-contributions/setting-guidelines-for-repository-contributors.
