On behalf of the Rakudo development team, I’m very happy to announce the November 2017 release of Rakudo Perl 6 #117. 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 2017 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 <http://rakudo.org/downloads/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 <http://rakudo.org/downloads/star/>.

Additionally, we invite you to make a donation to The Perl Foundation to sponsor Perl 6 development: <https://donate.perlfoundation.org/> (put “Perl 6 Core Development Fund” in the ‘Purpose’ text field) The next release of Rakudo (#118), is tentatively scheduled for 2017-12-16. A list of the other planned release dates is available in the “docs/release_guide.pod” file. The development team appreciates feedback! If you’re using Rakudo, do get back to us. Questions, comments, suggestions for improvements, cool discoveries, incredible hacks, or any other feedback – get in touch with us through (the above-mentioned) mailing list or IRC channel. Enjoy! Please note that recent releases have known issues running on the JVM. We are working to get the JVM backend working again but do not yet have an estimated delivery date. [^1]: See <http://moarvm.org/> [^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.
