Recently I released a new version of perlver utility. perlver and corresponding module Perl::MinimumVersion is a tool to determine minimum Perl version to run your program. New version, 1.22, should support almost all features added in Perl 5.5. I skipped features that are too complex to parse and regexes - PPI does not parse them. Also I added some features of Perl 5.6 that previously were not detected.
