 %changelog
+* Fri Dec  7 2018 Paul Howarth <paul@city-fan.org> - 1:4.00-1
+- Update to 4.00
+  - BACKWARD INCOMPATIBILITY: As JSON::XS 4.0 changed its policy and enabled
+    allow_nonref by default, JSON::PP also enabled allow_nonref by default
+  - Implement allow_tags that was introduced by JSON::XS 3.0
+  - Add boolean_values that was introduced by JSON::XS 4.0
+  - Allow literal tags in strings in relaxed mode, as JSON::XS 3.02 does
+  - Allow PERL_JSON_PP_USE_B environmental variable to restore old number
+    detection behavior for compatibility
+  - Various documentation updates
+- Drop provides filter, no longer needed
+
 * Fri Jul 13 2018 Fedora Release Engineering <releng@fedoraproject.org> - 1:2.97.001-418
 - Rebuilt for https://fedoraproject.org/wiki/Fedora_29_Mass_Rebuild
