+* Fri Feb 24 2017 Paul Howarth <paul@city-fan.org> - 1.815-1
+- Update to 1.815
+  - Fixed divide-by-zero error in MCE->yield
+  - Refactored code for the interval option by moving the code to the manager
+    process, which allows the manager process to accomodate the next available
+    worker ready to run; previously, a worker taking a long time resulted in
+    empty time slots
+  - Revised the description of posix_exit in MCE::Core.pod
+
 * Mon Feb 20 2017 Paul Howarth <paul@city-fan.org> - 1.814-1
