On behalf of the Rakudo development team, I'm pleased to announce the
June 2010 development release of Rakudo Perl #30 "Kiev". Rakudo is an
implementation of Perl 6 on the Parrot Virtual Machine (see
<http://www.parrot.org>). The tarball for the June 2010 release is
available from <http://github.com/rakudo/rakudo/downloads>.

Rakudo Perl follows a monthly release cycle, with each release named
after a Perl Mongers group. This release is named after the Perl
Mongers from the beautiful Ukrainian capital, Kiev. They recently
helped organize and participated in the Perl Mova + YAPC::Russia
conference, the хакмит (hackathon) of which was a particular success
for Rakudo. All those who joined the Rakudo hacking - from Kiev and
further afield - contributed spec tests as well as patches to Rakudo,
allowing various RT tickets to be closed, and making this month's
release better. Дякую!

Some of the specific changes and improvements occurring with this
release include:

* Rakudo now uses immutable iterators internally, and generally hides
their existence from programmers. Many more things are now evaluated

* Backtraces no longer report routines from Parrot internals. This
used to be the case in the Rakudo alpha branch as well, but this time
they are also very pleasant to look at.

* Match objects now act like real hashes and arrays.

* Regexes can now interpolate variables.

* Hash and array slicing has been improved.

* The REPL shell now prints results, even when not explicitly asked to
print them, thus respecting the "P" part of "REPL".

* Rakudo now passes 33,378 spectests. We estimate that there are about
39,900 tests in the test suite, so Rakudo passes about 83% of all

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 next release of Rakudo (#31) is scheduled for July 22, 2010. A
list of the other planned release dates and code names for 2010 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.

Have fun!
