+Subject: [PATCH] Fix for #2677 (#2705)
+
+* Update docs given https://github.com/yaml/go-yaml/pull/348
+
+* Fix for https://github.com/mikefarah/yq/issues/2677
+
+Depends on https://github.com/yaml/go-yaml/pull/348
+
+* Test for https://github.com/mikefarah/yq/issues/2677
+
+* Remove redundant check and add test case for explicit `!!merge` on `*+` traversal
+
+* Bump go.yaml.in/yaml/v4 from 4.0.0-rc.4 to 4.0.0-rc.5
