+* Mon Mar  2 2020 Paul Howarth <paul@city-fan.org> - 1:1.77-1
+- Update to 1.77
+  - When the parsed string contained an invalid time zone offset (parsed with
+    "%%z") like "-9999", the error handling set in the parser's constructor was
+    ignored and an exception was always thrown (GH#25)
+- Use %%{make_build} and %%{make_install}

 * Wed Jan 29 2020 Fedora Release Engineering <releng@fedoraproject.org> - 1:1.76-4
