Changes for version 1.6 - 2020-12-02
- Fixed confusing Changes entry about Perl's licensing terms.
- <KENTNL@cpan.org>, CPAN RT#132843
 
 - Added optional Changes testing (skipped unless AUTHOR_TESTING).
 - Reformatted Changes file as per CPAN::Changes::Spec.
 - Added optional POD coverage testing (skipped unless AUTHOR_TESTING).
 - Added optional Perl::Critic testing (skipped unless AUTHOR_TESTING).
 - Made code Perl::Critic clean.
 - Added optional POD testing (skipped unless AUTHOR_TESTING).
 - Included GitHub repository URLs in metadata now that source code has been uploaded to GitHub (as of version 1.5).
 - Included META.json file in addition to META.yml.
 - Set minimum required ExtUtils::MakeMaker version to 6.64 to ensure that all parameters used are supported, to save jumping through hoops to support earlier versions. (This should not be a problem since ExtUtils::MakeMaker 6.64 is easily installed into Perl 5.8.1 and above, that being the whole point of the new choice of minimum supported Perl version.)
 - Set minimum required Perl version to 5.8.1. This is in line with the minimum requirement of the "Perl Toolchain".
 - Corrected typo in a comment. [<dsteinbrunner@pobox.com>, CPAN RT#86336]
