# Announce: Rakudo Perl 6 compiler, Release #124 (2018.06)

On behalf of the Rakudo development team, I’m very happy to announce the
June 2018 release of Rakudo Perl 6 #124. Rakudo is an implementation of
Perl 6 on the Moar Virtual Machine[^1].

This release implements the 6.c version of the Perl 6 specifications.
It includes bugfixes and optimizations on top of
the 2015.12 release of Rakudo.

Upcoming releases in 2018 will include new functionality that is not
part of the 6.c specification, available with a lexically scoped
pragma. Our goal is to ensure that anything that is tested as part of the
6.c specification will continue to work unchanged. There may be incremental
spec releases this year as well.

The tarball for this release is available from <https://rakudo.org/files/rakudo>.

Please note: This announcement is not for the Rakudo Star
distribution[^2] — it’s announcing a new release of the compiler
only. For the latest Rakudo Star release, see
<https://rakudo.org/files/star>.

[^2]: 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, Perl 6 introductory
documentation, and other software that can be used with the Rakudo
compiler to enhance its utility.
