CPAN::Meta::History - history of CPAN Meta Spec changes


version 2.150010


The CPAN Meta Spec has gone through several iterations. It was originally written in HTML and later revised into POD (though published in HTML generated from the POD). Fields were added, removed or changed, sometimes by design and sometimes to reflect real-world usage after the fact.

This document reconstructs the history of the CPAN Meta Spec based on change logs, repository commit messages and the published HTML files. In some cases, particularly prior to version 1.2, the exact version when certain fields were introduced or changed is inconsistent between sources. When in doubt, the published HTML files for versions 1.0 to 1.4 as they existed when version 2 was developed are used as the definitive source.

Starting with version 2, the specification document is part of the CPAN-Meta distribution and will be published on CPAN as CPAN::Meta::Spec.

Going forward, specification version numbers will be integers and decimal portions will correspond to a release date for the CPAN::Meta library.
