The tarball for the June 2012 +release is available from . + +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 + +* p6doc is now shipped with Rakudo Star. It is a small collection of + user-oriented documentation, along with the `p6doc` script for viewing + them. + +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.

Bug reports about missing and broken +features are welcomed at . + +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 + in the release tarball. + +The development team thanks all of the contributors and sponsors +for making Rakudo Star possible.
