+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 February 2013 release of "Rakudo Star", a useful and
+usable distribution of Perl 6. The tarball for the February 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 2013.02.1 [0] of the
+Rakudo Perl 6 compiler [1], version 4.10.0 of the Parrot Virtual
+Machine [2], and various modules, documentation, and other
+resources collected from the Perl 6 community.
+Some of the new features added to this release include:
+* "Did you mean ..." suggestions for symbol-not-found errors
+* Compile-time optimization of some cases of junctions in boolean context
+* IO::Socket.get now works again with non-ASCII characters
+* constant folding for routines marked as 'is pure'
+* natively typed variables and better error reporting in the REPL
+* speed up eqv-comparison of Bufs
+* warnings for useless use of (some) literals, variables and constant
+ expressions in sink context
+This release also contains a range of bug fixes, improvements to error reporting
+and better failure modes.
+The following features have been deprecated or modified from previous
+releases due to changes in the Perl 6 specification, and are being removed
+or changed as follows:
+* .gist on a type object will return '(Typename)' instead of 'Typename()'.
+ If you want to get the class name directly, use $obj.^name
+* postcircumfix:<[ ]> and postcircumfix:<{ }> will become multi-subs rather
+ than multi-methods. Both at_pos and at_key will remain methods.
+* Unary hyper ops currently descend into nested arrays and hashes.
+ This will change to make them equivalent to a one-level map.
+* The Str.ucfirst builtin is deprecated; it will be replaced by Str.tc.
+* 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.
+* The ?-quantifier on captures in regexes currently binds the capture
+ slot to a List containing either zero or one Match objects; i.e., it
+ is equivalent to "** 0..1". In the future, the ?-quantifier will
+ bind the slot directly to a captured Match or to Nil. Existing code
+ can manage the transition by changing existing ?-quantifiers to
+ use "** 0..1", which will continue to return a List of matches.
+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
+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.
