On behalf of the Parrot team, I'm proud to announce Parrot 4.11.0, also known as "All together - Happy Birthday Lovebird". Parrot (http://parrot.org/) is a virtual machine aimed at running all dynamic languages.
Parrot 4.11.0 is available on Parrot's FTP site (ftp://ftp.parrot.org/pub/parrot/releases/devel/4.11.0/), or by following the download instructions at http://parrot.org/download. For those who would like to develop on Parrot, or help develop Parrot itself, we recommend using Git to retrieve the source code to get the latest and best Parrot code. 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 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.html and http://niner.name/Hybrid_Threads_for_the_Parrot_VM.pdf Summary: http://perl6advent.wordpress.com/2012/12/11/day-11-parrot-threads/ + New parrot cmdline option --numthreads + Export new dynpmc_class_<ClassName> types [GH #870]. + Changed core_ops library format and ops2c to contain the PBC_COMPAT only, not the parrot version triple.
