Parrot 4.11.0 "All together - Happy Birthday Lovebird" Released!

On behalf of the Parrot team, I'm proud to announce Parrot 4.11.0, also known as "All together - Happy Birthday Lovebird". Parrot is a virtual machine aimed at running all dynamic languages.

Threads are considered experimental. There are a known GC bugs when running large threads on darwin and sometimes linux. There are no known problems when running large single-threaded programs.
Reading from shared variables is transparent, writing must be done via scheduled updater subs on the owner thread.
You can use the API without using native OS threads by configuring --without-threads.

Parrot 4.11.0 is available on Parrot's FTP site, or by following the download instructions. For those who want to hack on Parrot or languages that run on top of Parrot, we recommend our organization page on GitHub, or you can go directly to the official Parrot Git repo on Github

To clone the Parrot Git repo into a directory called 'parrot', use the following:

    git clone git://github.com/parrot/parrot.git

If you want it to be in a directory other than 'parrot', then just give that as a second argument to clone:

    git clone git://github.com/parrot/parrot.git parrot_foo

Parrot 4.11.0 News:

    - Core
        + Parrot now supports fast and lightweight OS threads, based on Nat Tucks's
          initial GSoC work on green threads and then Stefan Seifert's extension
          to true parallel OS threads as hybrid threads.
          See http://wknight8111.blogspot.co.at/2010/08/gsoc-threads-chandons-results....
          and http://niner.name/Hybrid_Threads_for_the_Parrot_VM.pdf

        + Changed core_ops library format and ops2c to contain the PBC_COMPAT only,
          not the parrot version triple. Removed the duplicate PARROT_DYNOP_CORE_INIT
          cpp definition in include/parrot/oplib/core_ops.h, use only
          PARROT_CORE_OPLIB_INIT from config.h

        + Added getprotobyname method to the Socket PMC

    - Languages
        + nqp-rx tests updated from perl6/nqp-rx.git, and enabled to run on make test
    - Platforms
        + More compilation fixes on Windows without working mt.exe or ranlib=rem,
          enable smoking without git binary.
    - Tools
        + Re-enabled pbc_dump -h --header-only
        + Improved pmc2c, added more UNUSED(arg) macros [GH #836]. Parrot is now almost
          -Wunused-parameters safe.
    - Tests
        + failing Pod::Simple pod_todo.t tests are now skipped
        + added nqp-rx tests
