+
+On behalf of the Rakudo development team, I'm happy to announce the
+December 2010 release of Rakudo Perl #36 "New York".  Rakudo is an 
+implementation of Perl 6 on the Parrot Virtual Machine (see 
+<http://www.parrot.org>). The tarball for the December 2010 release
+is available from <http://github.com/rakudo/rakudo/downloads>.
+
+Please note: This announcement is not for the Rakudo Star distribution --
+it's announcing a new release of the compiler only.  For the latest
+Rakudo Star release, see <http://github.com/rakudo/star/downloads>.
+
+The Rakudo Perl compiler follows a monthly release cycle, with each release
+named after a Perl Mongers group. The December 2010 release is code named
+"New York" the first PM group, created by brian d foy, in tribute to Perl's
+23rd anniversary, which was celebrated on the 18th of this month.
+
+Some of the specific changes and improvements occurring with this
+release include:
+
+* new .trans algorithm
+
+* configuration improvements
+
+* several bug fixes
+
+For a more detailed list of changes, see "docs/ChangeLog".
+
+The development team thanks all of our contributors and sponsors for
+making Rakudo Perl possible, as well as those people who worked on 
+Parrot, the Perl 6 test suite and the specification.
+
+The following people contributed to this release:
+
+Moritz Lenz, Carl Masak, Solomon Foster, Kodi Arfer, Fernando Brito,
+Tomoki Aonuma, Nick Wellnhofer, Patrick R. Michaud, Abi Salloum, frettled,
+smashz and Jonathan Scott Duff.

+If you would like to contribute, see <http://rakudo.org/how-to-help>, ask on
+the perl6-compiler@perl.org mailing list, or ask on IRC #perl6 on freenode.
+
+The next release of Rakudo (#37) is scheduled for January 20, 2011.
+A list of the other planned release dates and code names for 2011 is
+available in the "docs/release_guide.pod" file.  In general, Rakudo
+development releases are scheduled to occur two days after each
+Parrot monthly release.  Parrot releases the third Tuesday of each month.
