+* Mon Jul  8 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
