On behalf of the Rakudo and Perl 6 development teams, I'm pleased to
the October 2016 release of "Rakudo Star", a useful and usable production
distribution of Perl 6. The tarball for the October 2016 release is
from http://rakudo.org/downloads/star/.

This is the fourth post-Christmas (production) release of Rakudo Star and
implements Perl v6.c. It comes with support for the MoarVM backend (all
tests pass on supported platforms).

Please note that this release of Rakudo Star is not fully functional with
JVM backend from the Rakudo compiler. Please use the MoarVM backend only.

In the Perl 6 world, we make a distinction between the language ("Perl 6")
specific implementations of the language such as "Rakudo Perl". This Star
release includes release 2016.10 of the Rakudo Perl 6 compiler, version
of MoarVM, plus various modules, documentation, and other resources
from the Perl 6 community.

There are some key features of Perl 6 that Rakudo Star does not yet handle
appropriately, although they will appear in upcoming releases. Some of the
not-quite-there features include:

+ advanced macros
+ non-blocking I/O (in progress)
+ some bits of Synopsis 9 and 11
+ There is an online resource at http://perl6.org/compilers/features that
the known implemented and missing features of Rakudo's backends and other
6 implementations.

In many places we've tried to make Rakudo smart enough to inform the
that a given feature isn't implemented, but there are many that we've
Bug reports about missing and broken features are welcomed at

See http://perl6.org/ for links to much more information about Perl 6,
including documentation, example code, tutorials, presentations, reference
materials, design documents, and other supporting resources. Some Perl 6
tutorials are available under the "docs" directory in the release tarball.

The development team thanks all of the contributors and sponsors for making
Rakudo Star possible. If you would like to contribute, see

or join us on IRC #perl6 on freenode.
