New features have been coming out with yearly releases since 2010's release of version 5.12.

But by 2010, many people already thought Perl5 was dead because Perl6 still hadn't shipped.

The really interesting stuff is actually happening on CPAN, with great extensions like:

* Type::Tiny https://metacpan.org/pod/Type::Tiny

* Kavorka https://metacpan.org/pod/Kavorka

* Moo https://metacpan.org/pod/Moo

* the Test2 suite of unit testing tools https://metacpan.org/pod/Test2::Suite
