+Announce: Rakudo Star - 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 June 2012 release of "Rakudo Star", a useful and
+usable distribution of Perl 6. The tarball for the May 2012
+release is available from <http://github.com/rakudo/star/downloads>.
+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 2012.06 [0] of the
+Rakudo Perl 6 compiler [1], version 4.5 of the Parrot Virtual
+Machine [2], and various modules, documentation, and other
+resources collected from the Perl 6 community.
+Here are some of the major improvements in this release over the
+previous distribution release.
+* Transitive longest-token matching in protoregexes
+* Longest token matching for alternations
+* Enhanced list and .map handling, including laziness fixes and performance
+ improvements
+* Can use an argument list with require
+* Compile time errors in loaded modules now show a module loading backtrace
+* String to number conversion now recognizes radix notation
+* The &push and &unshift functions can now autovivify
+* Rakudo is now compiled with the same regex engine that user-space
+ regexes use; some parsing bugs are fixed as a result
+This release also contains a range of bug fixes, improvements to error
+reporting and better failure modes. More exceptions are thrown as typed
+exceptions, and more meta-model errors have been fixed to properly
+report line numbers.
+This release contains an important breaking change to number parsing.
+Previously, a string such as "foo" would numify to 0. Now this will
+return a Failure.
+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:
+ * macros
+ * threads and concurrency
+ * Unicode strings at levels other than codepoints
+ * interactive readline that understands Unicode
+ * non-blocking I/O
+ * much of Synopsis 9
+There is a new online resource at http://perl6.org/compilers/features
+that lists the known implemented and missing features of Rakudo Star
+2012.06 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.
+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@perl.org
+mailing list, or join us on IRC #perl6 on freenode.
