+ + Chg : The new environment variable to enable thread tests on older
+ perls is PERL_FORCE_TEST_THREADS. Note that this variable
+ should only be turned on by authors.
+ + Chg : A large chunk of boilerplate XS code, which is also used in
+ other XS modules, has been factored out of the main .xs file
+ to a collection of .h files in the xsh subdirectory.
+ + Fix : This module can once again be built with strict C89 compilers.
+ + Fix : Update the Windows ActivePerl + gcc 3.4 workaround for
+ ExtUtils::MakeMaker 7.04. Thanks Christian Walde for reporting
+ and feedback on this issue.
+ + Fix : Segfaults when the module is loaded by several threads (or
+ Windows emulated processes) ran in parallel.
+ + Fix : Test failures of threads tests on systems with harsh resource
+ constraints causing the threads to exit() during run.

+ + Chg : perl 5.8.4 is now required (instead of 5.8.3).
+ + Fix : [RT #100202] : Fix for 5.21.6-to-be.
+ Thanks Father Chrysostomos for reporting and contributing a
+ patch.
+ + Fix : Be really compatible with the optional OP_PARENT feature.
+ + Tst : $ENV{$Config{ldlibpthname}} is now preserved on all platforms,
+ which will address failures of t/81-threads-teardown.t with
+ unusual compilers (like icc) that link all their compiled
+ objects to their own libraries.

+ + Add : Support for the PERL_OP_PARENT optional feature introduced in
+ perl 5.21.2.
+ + Doc : The CAVEATS section now warns about the global slowdown during
+ compilation caused by this pragma.
+ + Fix : [RT #86112] : Doesn't hook new PADRANGE op in Perl 5.18.
+ The PADRANGE optimization is now fully supported.
+ Thanks Dagfinn Ilmari Mannsåker for reporting.
+ + Fix : Segfaults in eval in an END block of a Win32 pseudo-fork.
+ + Fix : Segfaults during global destruction of a thread or a
+ pseudo-fork.
+ + Fix : Check functions are now replaced and restored in a thread-safe
+ manner, either by using the wrap_op_checker() function from perl
+ when it is available (starting from perl 5.16) or by taking the
+ OP_REFCNT mutex on older perls.
+ + Tst : Author tests are no longer bundled with this distribution.
+ They are only made available to authors in the git repository.
+ + Tst : Test failures of t/81-threads-teardown.t on Cygwin and Android
+ should have been addressed.
+ + Tst : Threads tests will not fail anymore if resources constraints
+ prevent the system from creating all the required threads.
+ + Upd : Metadata overhaul.
