 ## Unreleased
 
+* [shipping] Add `intlShippingSlowdown` integer feature flag to delay
+  international (non-US) shipments by N seconds via flagd with OpenTelemetry tracing
+  ([#346](https://github.com/open-telemetry/opentelemetry-demo/issues/346))
+* [collector] Add `transform/sanitize_logs` processor to work around
+  `otelcol.signal` scope attribute conflict with `otelcol.signal.output`
+  that causes OpenSearch/Elasticsearch mapping failures
+  ([#3321](https://github.com/open-telemetry/opentelemetry-demo/pull/3321))
 * [telemetry-docs] Add a new service to provide telemetry documentation based
   on Weaver
   ([#2794](https://github.com/open-telemetry/opentelemetry-demo/pull/2794))
