+    `placeholder.Placeholder.traverse()`.
+*   `placeholder.Predicate.dependent_channels()` was replaced with
+    `channel_utils.get_dependent_channels(Placeholder)`.
+*   `placeholder.Predicate.encode_with_keys(...)` was replaced with
+    `channel_utils.encode_placeholder_with_channels(Placeholder, ...)`.
+
+*   `placeholder.Predicate.from_comparison()` removed (was deprecated)
+*   enable `external_pipeline_artifact_query` for querying artifact within one pipeline
+*   Support `InputArtifact[List[Artifact]]` annotation in Python function custom component
