+* Mon May 11 2020 Paul Howarth <paul@city-fan.org> - 1.868-1
+- Update to 1.868
+  - Bug fix for UTF-8 issues during inter-process communication:
+    - This update required undoing optimizations specific to scalar args
+    - Essentially, IPC involves serialization for everything going forward
+    - Install Sereal::Encoder and Sereal::Decoder for better performance in
+      Perl 5.8.8+
+  - MCE options flush_stdout, flush_stderr, and flush_file now default to
+    enabled for the MCE->print, MCE->printf, and MCE->say output routines
+  - Improved MCE::Child with threads-like detach capability (see POD)
+  - Improved IPC in MCE::Queue with permanent fast-like dequeue including
+    dequeue_nb; going forward, the fast and barrier options are silently
+    ignored if specified (i.e. no-op)
+  - Improved IPC performance on Linux
+  - Completed threads-like detach capability in MCE::Child
+  - Resolved MCE::Channel failing when calling dequeue multiple times on an
+    ended channel
+  - MCE->say, MCE->print, and MCE->printf now return 1
