Perl5 had a period of slow releases in the 2000s, this changed in 2010 with the release of version 5.12. Since then, Perl 5 has been on a yearly release cycle. The current release is version 5.30.0. When it became clear Perl6 wasn't coming any time soon, some people left Perl. Others knuckled down and wrote some great code that made Perl5 into a much better language. With many core feature additions and deprecations, new CPAN modules, and tooling to support consistent work by teams, the Perl5 language is more expressive and better than ever.
Perl6 took forever, had major internal conflicts, but managed to survive and ship a specification in December 2015, version 6.c (6.a was an alpha version, and 6.b a beta). The Rakudo Perl6 compiler gets monthly releases, but most people install the Rakudo Star distribution, which bundles some extra modules and just makes life a bit easier. Rakudo Star began shipping "A usable Perl 6 compiler" in 2010. Regular releases tracked changes in the compiler.
The Perl6.c spec was announced in December 2015, and the first Rakudo to implement it was released at the same time. Rakudo Star, lagged a bit and released in January 2016.

The Perl 6.d spec was released in November 2018, and the Rakudo 2018.11 version defaults to supporting it.

If you liked Perl5 then, come back and give modern perl5 a try.
Perl6 is an amazingly expressive and fun language to write with.
