# Announce: Rakudo Perl 6 compiler, Release #128 (2018.11) | ||
|
||
On behalf of the Rakudo development team, I’m very happy to announce the | ||
November 2018 release of Rakudo Perl 6 #128. 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>. | ||
|
||
The changes in this release are outlined below: | ||

||
[^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. |
