+### 2.7.2
+
+* Fix rare panic that occurred when a querier modified results from ingesters and generators while they were being marshalled to proto. This bug also impacted query correctness on recent trace data by returning incomplete results before they were ready. ([#4790](https://github.com/grafana/tempo/pull/4790))

+### 2.7.0
+
 * Add `invalid_utf8` to reasons span metrics will discard spans. ([#4293](https://github.com/grafana/tempo/pull/4293)) We now catch values in your tracing data that can't be used as valid metrics labels. If you want span metrics by foo, but foo has illegal prom changes in it, then they won't be written.
 * Metrics-generators: Correctly drop from the ring before stopping ingestion to reduce drops during a rollout. ([#4101](https://github.com/grafana/tempo/pull/4101))
 * Correctly handle 400 Bad Request and 404 Not Found in gRPC streaming. ([#4144](https://github.com/grafana/tempo/pull/4144))
