* Tue Sep 03 2019 Paul Howarth <paul@city-fan.org> - 1.847-1
- Update to 1.847
- Obsolete RedHat MCE-1.840-Sereal-deps.patch file; this patch file is no

see https://www.perlmonks.org/?node_id=1214439
- Replaced "PF_UNIX" with "AF_UNIX" in MCE::Util
* Tue Aug 27 2019 Paul Howarth <paul@city-fan.org> - 1.846-1

* Mon Aug 26 2019 Paul Howarth <paul@city-fan.org> - 1.845-1
- Update to 1.845
- Croak if is_joinable, is_running, or join is called by a non-managed
process in MCE::Child; added LIMITATION section to the documentation

MCE::Child
- Added example (consumer requests item) to MCE::Channel documentation

via MCE->print($io, ...), printf, and say
- Support gather ⇒ MCE::Candy::out_iter_fh($io) using MCE::Candy
* Thu Aug 15 2019 Paul Howarth <paul@city-fan.org> - 1.844-1
- Update to 1.844
- Resolved MCE stalling when specifying max_retries with init_relay, ditto
for loop_timeout with init_relay on UNIX platforms
- Enhanced loop_timeout to handle workers dieing uncontrollably from any
user_tasks (i.e. task_id ≥ 0); previously, only task_id == 0
- Improved IPC on the Windows platform for edge case when a worker is
awaiting input while the manager process is restarting a worker
- MCE, MCE::Child workers exit immediately upon receiving a SIGSEGV signal;
this safeguards IPC from stalling inside the manager process
- Enhanced the _wait_one private function in MCE::Child
- Removed Prima from the list for auto-enabling the posix_exit option; Prima
(since 1.52) is parallel safe during global cleanup
- Reached 100% Pod coverage
* Wed Jul 24 2019 Paul Howarth <paul@city-fan.org> - 1.843-1
- Update to 1.843
- Updated results in MCE::Child (Parallel::ForkManager-like demonstration)
- Completed missing interrupt signal-safety for the non-blocking methods in
MCE::Channel::Mutex and MCE::Channel::Threads
* Mon Jul 22 2019 Paul Howarth <paul@city-fan.org> - 1.842-1
- Update to 1.842
- Fixed race condition abnormalities in MCE::Child
- Added Parallel::ForkManager-like demonstration to MCE::Child
* Mon Jul 08 2019 Paul Howarth <paul@city-fan.org> - 1.841-1
- Update to 1.841
- Disabled t/04_channel_threads testing on Unix platforms for Perl less than
5.10.1; basically, the MCE::Channel::Threads implementation is not supported
on older Perls unless the OS vendor applied upstream patches (i.e. works on
RedHat/CentOS 5.x running Perl 5.8.x)
- Added LIMITATIONS section to MCE::Channel::Threads
* Sun Jul 07 2019 Paul Howarth <paul@city-fan.org> - 1.840-1
- Update to 1.840
New Features
- Added MCE::Mutex::Channel2 providing two locks using a single channel; the
secondary lock is accessible by calling methods with the '2' suffix, e.g.
primary mutex ->lock, ->unlock; secondary mutex ->lock2, ->unlock2
- Added MCE::Channel providing queue-like and two-way communication
supporting threads and processes
- Added MCE::Child and compatibility with Perl 5.8; MCE::Child is based on
MCE::Hobo, but using MCE::Channel for data retrieval without involving a
shared-manager process
- Added MCE::Channel examples { channel1.pl and channel2.pl } using threads
and MCE::Child respectively
Enhancements
- IPC update; removed unnecessary overhead including private methods _sysseek
and _syswrite from MCE::Util (no longer needed)
- Improved MCE->do, now callable by workers and the manager process
- Updated MCE::{ Flow, Grep, Loop, Map, Step, and Stream } documentation on
passing an array reference versus a list for deeply input data
- Updated and re-organized the top-level MCE documentation, particularly
improved clarity for the 'MCE Models' section
- Removed MANIFEST.SKIP
- Update MCE::Channel POD documentation
