+* [ENHANCEMENT] tempo-query: separate tls settings for server and client [#4177](https://github.com/grafana/tempo/pull/4177) (@frzifus)
+* [ENHANCEMENT] Pushdown collection of results from generators in the querier [#4119](https://github.com/grafana/tempo/pull/4119) (@electron0zero)
+* [ENHANCEMENT] Send semver version in api/stattus/buildinfo for cloud deployments [#4110](https://github.com/grafana/tempo/pull/4110) [@Aki0x137]
+* [ENHANCEMENT] Speedup tempo-query trace search by allowing parallel queries [#4159](https://github.com/grafana/tempo/pull/4159) (@pavolloffay)
+* [ENHANCEMENT] Speedup DistinctString and ScopedDistinctString collectors [#4109](https://github.com/grafana/tempo/pull/4109) (@electron0zero)
+* [CHANGE] tempo-cli: add support for /api/v2/traces endpoint [#4127](https://github.com/grafana/tempo/pull/4127) (@electron0zero)
+  **BREAKING CHANGE** The `tempo-cli` now uses the `/api/v2/traces` endpoint by default, 
+  please use `--v1` flag to use `/api/traces` endpoint, which was the default in previous versions.
+* [ENHANCEMENT] Speedup collection of results from ingesters in the querier [#4100](https://github.com/grafana/tempo/pull/4100) (@electron0zero)

+* [ENHANCEMENT] Add disk caching in ingester SearchTagValuesV2 for completed blocks [#4069](https://github.com/grafana/tempo/pull/4069) (@electron0zero)
+* [BUGFIX] Replace hedged requests roundtrips total with a counter. [#4063](https://github.com/grafana/tempo/pull/4063) [#4078](https://github.com/grafana/tempo/pull/4078) (@galalen)
+* [BUGFIX] Metrics generators: Correctly drop from the ring before stopping ingestion to reduce drops during a rollout. [#4101](https://github.com/grafana/tempo/pull/4101) (@joe-elliott)
+* [BUGFIX] Bring back application-json content-type header. [#4121](https://github.com/grafana/tempo/pull/4121) (@javiermolinar)

+* [BUGFIX] Pushes a 0 to classic histogram's counter when the series is new to allow Prometheus to start from a non-null value. [#4140](https://github.com/grafana/tempo/pull/4140) (@mapno)
+* [CHANGE] TraceByID: don't allow concurrent_shards greater than query_shards. [#4074](https://github.com/grafana/tempo/pull/4074) (@electron0zero)
+* **BREAKING CHANGE** tempo-query is no longer a jaeger instance with grpcPlugin. Its now a standalone server. Serving a grpc api for jaeger on `0.0.0.0:7777` by default. [#3840](https://github.com/grafana/tempo/issues/3840) (@frzifus)
+* [CHANGE] **BREAKING CHANGE** The dynamic injection of X-Scope-OrgID header for metrics generator remote-writes is changed. If the header is aleady set in per-tenant overrides or global tempo configuration, then it is honored and not overwritten. [#4021](https://github.com/grafana/tempo/pull/4021) (@mdisibio)
+* [CHANGE] **BREAKING CHANGE** Migrate from OpenTracing to OpenTelemetry instrumentation. Removed the `use_otel_tracer` configuration option. Use the OpenTelemetry environment variables to configure the span exporter [#3646](https://github.com/grafana/tempo/pull/3646) (@andreasgerstmayr)
+  To continue using the Jaeger exporter, use the following environment variable: `OTEL_TRACES_EXPORTER=jaeger`.
+* [CHANGE] No longer send the final diff in GRPC streaming. Instead we rely on the streamed intermediate results. [#4062](https://github.com/grafana/tempo/pull/4062) (@joe-elliott)
+* [CHANGE] Update Go to 1.23.1 [#4146](https://github.com/grafana/tempo/pull/4146) [#4147](https://github.com/grafana/tempo/pull/4147) (@javiermolinar)

 * [FEATURE] TraceQL support for instrumentation scope [#3967](https://github.com/grafana/tempo/pull/3967) (@ie-pham)
