Parrot 4.2.0 News:
- API Changes
+ The signature of getprop was changed from (PMC,String,PMC) to
(PMC, PMC,String) for consistency
- Core
+ Parrot Calling Conventions (pcc) now reuses Continuation PMCs
internally, which reduces GC work by 25% and improves
the fib.pir benchmark by 6%
+ Winxed snapshot updated to 1.6.devel 44a04cfa7b
+ Improved the detection of Clang-ish compilers during configuration
+ Fixed a possible segfault bug when reading packfiles with no
constants or main_sub
+ By default, Parrot has now elevated these GCC warnings to errors
during compile time:
implicit-function-declaration, undef, missing-braces,
nested externs, old-style-definition, strict-prototypes,
+ The OS Dynamic PMC now has separate functions to unlink a file
and remove an empty directory (rmdir)
+ Fix building on Cygwin due to an improperly named DLL file
+ Various small bug fixes pointed out by static and dynamic analysis
tools
- Branches
+ Work on M0 continues now in the m0 branch, which contains both
implementations (currently C and Perl) and specification.
+ Good progress has been made on the threads branch which builds
on the green_threads branch. This gets Parrot much closer to
being able to utilize multiple CPU cores seemlessly. More details
at http://niner.name/Hybrid_Threads_for_the_Parrot_VM.pdf
- Documentation
+ New release manager documentation for parrot.github.com :
http://git.io/parrot-github-guide
- Community
+ Parrot was accepted to Google Summer of Code 2012!
