if I’m looking at this right, Perl 5.13.10 is the earliest Perl version where the toolchain supports META.json out of the box. Specifically, 5.13.9 was the first perl to ship JSON::PP in core, but its CPAN.pm and Parse::CPAN::Meta lack META.json support. They were added in Parse::CPAN::Meta 1.41_01 and CPAN.pm 1.94_65, both of which were included in 5.13.10 (or rather, Parse::CPAN::Meta was upgraded to 1.44). In practice that means Perl 5.14.0 is the first Perl that can install dists with a JSON-only META out of the box. Regards, -- Aristotle Pagaltzis // <http://plasmasturm.org/>
