Subject: Announce: Rakudo Star 2010.08 released
To: perl6-compiler en perl.org, perl6-language en perl.org,
perl6-users en perl.org, parrot-dev en lists.parrot.org


On behalf of the Rakudo and Perl 6 development teams, I'm happy to
announce the August 2010 release of "Rakudo Star", a useful and usable
distribution of Perl 6.  The tarball for the August 2010 release is
available from <http://github.com/rakudo/star/downloads>.

Rakudo Star is aimed at "early adopters" of Perl 6.  We know that
it still has some bugs, it is far slower than it ought to be, and
there are some advanced pieces of the Perl 6 language specification
that aren't implemented yet.  But Rakudo Perl 6 in its current form
is also proving to be viable (and fun) for developing applications
and exploring a great new language.  These "Star" releases are
intended to make Perl 6 more widely available to programmers, grow
the Perl 6 codebase, and gain additional end-user feedback about the
Perl 6 language and Rakudo's implementation of it.

In the Perl 6 world, we make a distinction between the language
("Perl 6") and specific implementations of the language such as
"Rakudo Perl".  The August 2010 Star release includes release #32
of the Rakudo Perl 6 compiler [1], version 2.7.0 of the Parrot
Virtual Machine [2], and various modules, documentation,
and other resources collected from the Perl 6 community.

This release of Rakudo Star adds the following features over the
previous Star release:
 * Nil is now undefined
 * Many regex modifiers are now recognized on the outside of regexes
 * Mathematic and range operations are now faster (they're still slow,
   but they're significantly faster than they were in the previous release)
 * Initial implementations of .pack and .unpack
 * MAIN can parse short arguments
 * Removed a significant memory leak for loops and other repeated blocks

This release (temporarily?) omits the Config::INI module that was
included in the 2010.07 release, as it no longer builds with the
shipped version of Rakudo.  We hope to see Config::INI return soon.

There are some key features of Perl 6 that Rakudo Star does not
yet handle appropriately, although they will appear in upcoming
releases.  Thus, we do not consider Rakudo Star to be a
"Perl 6.0.0" or "1.0" release.  Some of the not-quite-there
features include:
 * nested package definitions
 * binary objects, native types, pack and unpack
 * typed arrays
 * macros
 * state variables
 * threads and concurrency
 * Unicode strings at levels other than codepoints
 * pre and post constraints, and some other phasers
 * interactive readline that understands Unicode
 * backslash escapes in regex <[...]> character classes
 * non-blocking I/O
 * most of Synopsis 9
 * perl6doc or pod manipulation tools

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.

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.
An updated 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 en perl.org
mailing list, or join us on IRC #perl6 on freenode.

Rakudo Star releases are created on a monthly cycle or as needed
in response to important bug fixes or improvements.  The next planned
release of Rakudo Star will be on September 28, 2010.
