## A useful, usable, "early adopter" distribution of Perl 6

On behalf of the Rakudo and Perl 6 development teams, I'm happy to
announce the November 2013 release of "Rakudo Star", a useful and usable
distribution of Perl 6. The tarball for the November 2013 release is
available from <http://rakudo.org/downloads/star/>. A Windows .MSI
version of Rakudo star will usually appear in the downloads area
shortly after the tarball release.

In the Perl 6 world, we make a distinction between the language
("Perl 6") and specific implementations of the language such as
"Rakudo Perl". This Star release includes [release 2013.11] of the
[Rakudo Perl 6 compiler], version 5.9.0 of the [Parrot Virtual
Machine], plus various modules, documentation, and other resources
collected from the Perl 6 community.

[release 2013.11]:
     https://github.com/rakudo/rakudo/blob/nom/docs/announce/2013.11.md
[Rakudo Perl 6 compiler]: http://github.com/rakudo/rakudo
[Parrot Virtual Machine]: http://parrot.org

Some of the new features added to this release include:

+ Order::Increase/Decrease are deprecated.  Please use Order::Less/More.
+ Leading whitespace is ignored for :sigspace
+ Better null pattern detection in regexes
+ improved run()/shell(), these return Proc::Status-objects now
+ The "gethostname" function implemented
+ Performance optimization: unfold junctions in 'when' clauses

This release also contains a range of bug fixes, improvements to error
reporting and better failure modes.

Please note that this release of Rakudo Star does not support the JVM
backend from the Rakudo compiler. While the JVM backend mostly 
implements the same features as the Parrot backend, many bits are still 
missing, most prominently the native call interface.
We hope to provide a JVM-based Rakudo Star release soon.

The following notable features have been deprecated or modified from 
previous releases due to changes in the Perl 6 specification, and are 
planned to be removed or changed as follows:

   * All unary hyper ops currently descend into nested arrays and
     hashes. In the future, those operators and methods that are
     defined "nodal" will behave like a one-level map.

There are some key features of Perl 6 that Rakudo Star does not yet
handle appropriately, although they will appear in upcoming releases.
Some of the not-quite-there features include:

   * advanced macros
   * threads and concurrency (in work for the JVM backend)
   * Unicode strings at levels other than codepoints
   * interactive readline that understands Unicode
   * non-blocking I/O
   * much of Synopsis 9 and 11

There is an online resource at <http://perl6.org/compilers/features>
that lists the known implemented and missing features of Rakudo and
other Perl 6 implementations.

In many places we've tried to make Rakudo smart enough to inform the
programmer that a given feature isn't implemented, but there are many
that we've missed. Bug reports about missing and broken features are
welcomed at <rakudobug@perl.org>.

See <http://perl6.org/> for links to much more information about
Perl 6, including documentation, example code, tutorials, reference
materials, specification documents, and other supporting resources. A
draft of a Perl 6 book is available as docs/UsingPerl6-draft.pdf in
the release tarball.

The development team thanks all of the contributors and sponsors for
making Rakudo Star possible. If you would like to contribute, see
<http://rakudo.org/how-to-help>, ask on the <perl6-compiler@perl.org>
mailing list, or join us on IRC \#perl6 on freenode.
