 %changelog
+* Tue Aug 28 2018 Paul Howarth <paul@city-fan.org> - 1.839-1
+- Update to 1.839
+  - Seeds the Math::Random::MT::Auto generator automatically when present in
+    MCE::Hobo, similarly to Math::Random and Math::Prime::Util, to avoid child
+    processes sharing the same seed value as the parent and each other; the new
+    seed is computed using the current seed
+  - Updated MCE::Shared::Cache to support optional argument "expires_in" for
+    set and sugar methods
+  - Updated MCE::Shared documentation
+  - Bumped MCE dependency to 1.837
+
 * Fri Jul 13 2018 Fedora Release Engineering <releng@fedoraproject.org> - 1.838-3
 - Rebuilt for https://fedoraproject.org/wiki/Fedora_29_Mass_Rebuild
