# Announce: Rakudo Perl 6 compiler, Development Release #86 (“Cluj”)

On behalf of the Rakudo development team, I’m happy to announce the March
2015 release of Rakudo Perl 6 #86 “Cluj”. Rakudo is an implementation of
Perl 6 on the Moar Virtual Machine[^1] and the Java Virtual Machine. The
tarball for this release is available from <http://rakudo.org/downloads/rakudo/>.

Please note: This announcement is not for the Rakudo Star
distribution[^3] --- it’s announcing a new release of the compiler
only. For the latest Rakudo Star release, see
<http://rakudo.org/downloads/star/>.

As described by pmichaud in a recent blog post:

  http://pmthium.com/2015/02/suspending-rakudo-parrot/

this is the first release of Rakudo that does *not* support Parrot [^2] as a
backend.  Whether Parrot support can be restored at some point in the future,
really depends on people with tuits making the necessary changes.  In that
light, I would like to emphasize the last paragraph of said blog post:

    If there are people that want to work on refactoring Rakudo’s support
    for Parrot so that it’s more consistent with the other VMs, we can
    certainly point them in the right direction. For the GLR this will
    mainly consists of migrating parrot-specific code from Rakudo into
    NQP’s APIs. For the NSA and NFG work, it will involve developing a lot
    of new code and feature capabilities that Parrot doesn’t possess.

The Rakudo Perl compiler follows a monthly release cycle, with each
release named after a Perl Mongers group. This release is named after
Cluj.pm which just celebrated its third birthday.

Some of the changes in this release are outlined below:

These are only some of the changes in this release. For a more

[^3]: What’s the difference between the Rakudo compiler and the Rakudo
Star distribution?

The Rakudo compiler is a compiler for the Perl 6 language.
Not much more.

The Rakudo Star distribution is the Rakudo compiler plus a selection
of useful Perl 6 modules, a module installer, the most recent
incarnation of the “Using Perl 6” book, and other software that can
be used with the Rakudo compiler to enhance its utility.  Rakudo Star
is meant for early adopters who wish to explore what’s possible with
Rakudo Perl 6 and provide feedback on what works, what doesn’t, and
what else they would like to see included in the distribution.
