+package:
+  name: confluent-kafka
+  # Upstream versioning is too weird that we need to work-around it.
+  # Release Monitor returns the latest version as `7.7.0-314-ccs` format:
+  # https://release-monitoring.org/api/v2/versions/?project_id=371656
+  # In order to make the `update:` section happy:
+  # 1. We need to transform it by replacing the last `-` with `.` to match
+  # with the `version:` field.
+  # 2. Created a new variable `mangled-package-version` to append `-ccs` to the
+  # version.
+  version: 7.8.0.3
