+* Mon Nov  6 2017 Paul Howarth <paul@city-fan.org> - 0.42-1
+- Update to 0.42
+  - Fixed checks for whether a class is loaded in light of upcoming
+    optimization in Perl 5.28 (GH#12)
+  - The Perl library claimed it provided types named LaxVersionStr and
+    StrictVersionStr but they were really named LaxVersion and StrictVersion;
+    the names have now been fixed to match the documentation, so they are
+    LaxVersionStr and StrictVersionStr
