# Announce: Rakudo Perl 6 compiler, Development Release #88 ("Dresden") | ||
|
||
On behalf of the Rakudo development team, I'm happy to announce the May | ||
2015 release of Rakudo Perl 6 #88 "Dresden". Rakudo is an implementation of | ||
Perl 6 on the Moar Virtual Machine[^1] and the Java Virtual Machine. The | ||
tarball for this release is available from <http://rakudo.org/downloads/rakudo/>. | ||
|
||
Please note: This announcement is not for the Rakudo Star | ||
distribution[^2] --- it's announcing a new release of the compiler | ||
only. For the latest Rakudo Star release, see | ||
<http://rakudo.org/downloads/star/>. | ||
|
||
The Rakudo Perl compiler follows a monthly release cycle, with each | ||
release named after a Perl Mongers group. This month's release is named after | ||
Dresden, where this year's German Perl Workshop happened. | ||
|
||
Some of the changes in this release are outlined below: | ||
|
||
* NFG, NFC, NFD, Uni | ||
* Implemented CLIENT:: (nearest CALLER:: from different package) | ||
* Implemented "is nodal" for signalling behaviour under hypers | ||
* Rudimentary tab completion available via the Linenoise module | ||
* "unit" declaration needed for blockless packages | ||
* Various API changes for the Great List Refactor, such as... | ||
+ 'for' loops not longer flatten; use 'for flat' for that | ||
+ .map no longer flattens, map as a listop does. Use .flatmap to get the | ||
old behavior | ||
+ Likewise other methods that used to flatten their invocant no longer do: | ||
all, any, one, none, unique, squish, min, max, minmax, classify, and categorize | ||
+ Nil no longer iterates like the empty List. Use () or Empty instead. | ||
* .pick($n)/roll($n) now always return lists, even when $n == 1 | ||
* $?FILE is now always an absolute path | ||
* The "is cached" trait no longer works on methods, throws a NYI instead | ||
* Method .map should be used instead of .for | ||
* Test.pm functions are now kebab-cased (e.g. throws_like -> throws-like) | ||
* Hashes use much less memory on Moar | ||
* The REPL is strict by default now, that leaves only '-e' lines to be lax | ||
* site/lib is now in the C library (.dll/.so/.dylib etc) search path | ||
* generating backtraces is now lazy, improving the speed of e.g. warnings | ||
* Implement new @*INC handling (about 30% faster startup time) | ||
(bare startup time is now below 100 ms on some machines) | ||
* Implemented CUnions which map to the union C type definition for NativeCall | ||
* Implemented HAS declarator for attributes to mark it embedded into the | ||
CStruct or CUnion | ||
|
||
These are only some of the changes in this release. For a more | ||
detailed list, see "docs/ChangeLog". | ||

A list of the other planned release dates and code names for future | ||
releases is available in the "docs/release_guide.pod" file. A Rakudo | ||
development release typically occurs a few days (often two) after the | ||
third Tuesday of each month. | ||

[^2]: What's the difference between the Rakudo compiler and the Rakudo | ||
Star distribution? | ||
|
||
The Rakudo compiler is a compiler for the Perl 6 language. | ||
Not much more. | ||
|
||
The Rakudo Star distribution is the Rakudo compiler plus a selection | ||
of useful Perl 6 modules, a module installer, the most recent | ||
incarnation of the "Using Perl 6" book, and other software that can | ||
be used with the Rakudo compiler to enhance its utility. Rakudo Star | ||
is meant for early adopters who wish to explore what's possible with | ||
Rakudo Perl 6 and provide feedback on what works, what doesn't, and | ||
what else they would like to see included in the distribution. |
