The latest development release of perl is here: https://metacpan.org/release/PCM/perl-5.21.3 And the perldeltas for the recent releases are: 5.21.3: https://metacpan.org/pod/release/PCM/perl-5.21.3/pod/perldelta.pod 5.21.2: https://metacpan.org/pod/release/PCM/perl-5.21.3/pod/perl5212delta.pod 5.21.1: https://metacpan.org/pod/release/PCM/perl-5.21.3/pod/perl5211delta.pod 5.21.0: https://metacpan.org/pod/release/PCM/perl-5.21.3/pod/perl5210delta.pod ..but as others have said, you don't 'use UNIVERSAL' directly - in fact the word 'UNIVERSAL' should never have to appear in your code. The subs on the UNIVERSAL class are available to your class already, as it is the granddaddy of all classes. just do $class->isa, $obj->isa etc.
