+* Thu Mar  3 2022 Paul Howarth <paul@city-fan.org> - 2:1.57-1
+- Update to 1.57
+  - The last release would die if Sub::Util was not available, but this
+    should just be an optional requirement (GH#131); this is the second

+    that DateTime can be loaded if Sub::Util is not installed, which will
+    hopefully prevent a third occurrence of this bug
