The Parrot VM is no longer being actively developed.
Last commit: 2017-10-02
The role of Parrot as VM for Perl 6 (now "Raku") has been filled by MoarVM, supporting the Rakudo compiler.

https://rakudo.org/

Parrot, as potential VM for other dynamic languages, never supplanted the existing VMs of those languages.
