On behalf of the Rakudo development team, I'm very happy to announce the February 2016 release of Rakudo Perl 6 #96. Rakudo is an implementation of Perl 6 on the Moar Virtual Machine

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, but no new features.

Upcoming releases in 2016 will include new functionality that is not part of the 6.c specification, available with a lexically scoped pragma. Our goal is to insure 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[^1] --- it's announcing a new release of the compiler only. For the latest Rakudo Star release, see http://rakudo.org/downloads/star/.

The Rakudo Perl compiler follows a monthly release cycle, but please bear with us post-Christmas. We are working hard to insure that we don't break anything now that we have a released spec, and it make take us a few months to settle back into a rhythm.

The changes in this release are outlined below:

New in 2016.02:

• Fixes:

  • Many memory leaks fixed in MoarVM
  • Set.hash now returns an object hash (RT #127402)
  • Use the order of arguments in usage display, rather than hash order
  • Specifying ::a now gives proper compile time error (RT #127504)
  • Enums with a type object now fail with an NYI error
  • .first(:end) on uncached iterators no longer fails

• Additions:

  • REPL now supports multi-line statements (experimental)
  • Can now uninstall distributions

• Efficiency:

  • Str.trans can now be up to 160x fas ter
  • @a.chrs now 3x faster, chrs(@a) now 9x faster <

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]: 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.
