+# Announce: Rakudo Star Release 2013.09
+## 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 September 2013 release of "Rakudo Star", a useful and usable
+distribution of Perl 6. The tarball for the September 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 2013.09] of the
+[Rakudo Perl 6 compiler], version 5.5.0 of the [Parrot Virtual
+Machine], plus various modules, documentation, and other resources
+collected from the Perl 6 community.
+[release 2013.09]:
+ https://github.com/rakudo/rakudo/blob/nom/docs/announce/2013.09.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:
++ candidate argument to bless removed (per spec change)
++ @a.VAR.name and %h.VAR.name implemented
++ The $var.++ and $var.() syntaxes work
++ tr/// implemented
++ Sockets on JVM implemented
++ Sets/Bags/KeySet/KeyBag now up to spec, except for the empty set symbol '∅'
+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 small IO bits are still
+missing, rendering some crucial parts like the module installer unusable.
+We hope to provide a JVM-based Rakudo Star release soon.
+The following 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:
+ * `postcircumfix:<[ ]>` and `postcircumfix:<{ }>` will become
+ multi-subs rather than multi-methods *IN THE NEXT RELEASE* of Rakudo
+ Star. Both at_pos and at_key will remain methods.
+ * 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.
+ * The Str.ucfirst builtin is deprecated; it will be replaced by
+ Str.tc. In the next Rakudo Star release, use of Str.ucfirst will actually
+ generate a warning upon first usage.
+ * Leading whitespace in rules and under :sigspace will no longer be
+ converted to `<.ws>`. For existing regexes that expect this
+ conversion, add a `<?>` in front of leading whitespace to make it
+ meta again.
+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
+ * 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.
