I am delighted to announce Pugs 6.2.10, released during a slashdotting
on geoffb's "Optimizing for Fun" column:
http://developers.slashdot.org/article.pl?sid=05/10/09/1831219
The release tarball will be available from CPAN shortly:
http://pugscode.org/dist/Perl6-Pugs-6.2.10.tar.gz
SIZE = 2394516
SHA1 = 3d8669fdccc3616c99cdde68659759b8b5782859
With two months of development, this release features more tightly
integrated JavaScript and Perl5 code generator backends, a library
interface to the Pugs system via support for the Haskell Cabal
frameworks, as well as many new tests.
After the release, the push toward 6.28.0 will begin in earnest, with
the newly specified container model and object model integrated back to
the main runtime, fleshing out support for the remaining OO features.
Again, thanks to all the lambdacamels for building this new ship with me. :)
Enjoy!

= Changes for 6.2.10 (r7520) - Oct 10, 2005
== Feature Changes
=== Shared components
* Support for the Haskell Cabal framework, exposing Pugs as a library to
other Haskell users, paving the way for use in IDEs, as well as future
Inline::Pugs and Inline::GHC modules
* Adopted the code convention of expanding literal tab chars to spaces
* JavaScript backend can be invoked with `pugs -B JS`
* Perl 5 backend can be invoked with `pugs -B Perl5`
* Pugs will now compile version ranges in 'use/require' statements
* Significant backend enhancements; see below
* `$?PUGS_BACKEND` can be used to tell which runtime is in use
* `exec` emulated (partially) on Win32
=== JavaScript backend
* Passes 91% of the main test suite (including TODO failures)
* Integrated with MetaModel 1.0
* Faster code generation, taking advantage of `-CPerl5` output.
* Switched to continuation passing style (CPS) to properly support
`return()`, `&?CALLER_CONTINUATION`, coroutines, and `sleep()`
* Improved support for binding and autodereferentiation
* Initial support for multi subs
* Initial support for symbolic dereferentiation
* List construction no longer creates new containers
* Miscellaneous performance improvements
* Named-only arguments (`+$x` and `++$x`) can't be passed positionally
anymore
* Parts of the Prelude can be written in Perl 5 now to improve performance
* Perl 5-like regular expressions mostly working
* Proper UTF-8 handling
* Support for "monkey-but" (`$foo but {...}`)
* Support for `$CALLER::` and `$OUTER::`
* Support for `lazy {...}` blocks for delayed evaluation
* Support for `temp` and `let` declarations
* Support for array and hash autovivification
* Support for array and hash slices
* Support for evaluating expressions in the PIL2JS shell (`:e <exp>`)
* Support for junctions
* Support for loading JSAN modules by using `use jsan:Module.Name`
* Support for lvalue subroutines (`foo() = ...`)
* Support for slurpy hashes in subroutine signatures
* Support for the `Proxy` class (not yet user-visible)
* Support for the `eqv` operator
* Using `for` with only one element to loop over works now
* `int()` works correctly on special values like `Inf` or `NaN` now
* `substr()` returns a r/w proxy: `substr($str, $pos, $len) = $replacement)`
=== Perl 5 backend
* Passes 33% of the main test suite (including TODO failures)
* Integrated with the Perl 5 edition of MetaModel 2.0
* Compiles and runs Perl 6 version of `Test.pm`
* Infinite lazy lists, Pairs, References, and intrinsic classes
* Multi Sub, Class, Match, exceptions, types and subtypes
* Scalar, Hash and Array containers, with tieing, binding and read-onlyness
* Support for an extensive list of operators
* Supports eval() with Perl 5 and Perl 6 code
* `%ENV` is shared with Perl 5; [EMAIL PROTECTED] is separate from [EMAIL
PROTECTED]::INC`
== Bug Fixes
=== Shared components
* Fixed `foo {1}.blah` being misparsed as `foo({1}).blah`
* Fixed a hashref infinite loop
* Fixed infinite loop on sub { 1 }.pairs
* Multiple `sub foo` no longer silently means `multi foo`
=== JavaScript backend
* Fixed evaluation order of assignments and bindings
* Fixed `.values` and `.kv` to return aliases
== Bundled Modules
=== New Perl 6 modules
* Perl6-Container-Array, Perl6-Value-List: prototype modules for
implementing Lazy lists in Perl 6.
* Log-Selective
* Cipher - Cipher API suite for cryptographic ciphers
* FA-DFA
=== Updated modules
* Locale-KeyedText: Synchronized with p5 version 1.6.2
* Test-Builder: new APIs, including test_pass() and test_fail()
=== Experimental modules (in misc/, not installed)
* Blondie, prototype compiler for native code generation and
type-inferencing with Attribute Grammers
* XML::SAX
* Getopt::Long
* Rosetta-Incubator, a complete set of Rosetta[|::*] and
SQL::Routine[|::*] modules, restarted development at 2005.09.29
== Test, Examples and Documentations
* Many new tests and test refactoring, we now have 10300+ tests
* Documentation for draft GC API at `docs/notes/GC.pod`
* Data file for curcular prelude exploratory diagram at
`docs/notes/compilation_of_circular_prelude.graffle`, some examples at
`docs/notes/circular_prelude_stuff.pl`
* Collaborative journal at `/docs/journal`
* Autrijus's CUFP talk at `/mirror/pugs/docs/talks/cufp2005.txt`
* Theory Model proposal at `docs/notes/theory.pod`
