* [CHANGE] **BREAKING CHANGE** Add maximum spans per span set. Users can set `max_spans_per_span_set` to 0 to obtain the old behavior. [#4275](https://github.com/grafana/tempo/pull/4383) (@carles-grafana)
* [CHANGE] slo: include request cancellations within SLO [#4355] (https://github.com/grafana/tempo/pull/4355) (@electron0zero)
request cancellations are exposed under `result` label in `tempo_query_frontend_queries_total` and `tempo_query_frontend_queries_within_slo_total` with `completed` or `canceled` values to differentiate between completed and canceled requests.
* [CHANGE] update default config values to better align with production workloads [#4340](https://github.com/grafana/tempo/pull/4340) (@electron0zero)
* [CHANGE] Add query-frontend limit for max length of query expression [##4397](https://github.com/grafana/tempo/pull/4397) (@electron0zero)
* [CHANGE] fix deprecation warning by switching to DoBatchWithOptions [#4343](https://github.com/grafana/tempo/pull/4343) (@dastrobu)
* [CHANGE] **BREAKING CHANGE** The Tempo serverless is now deprecated and will be removed in an upcoming release [#4017](https://github.com/grafana/tempo/pull/4017/) @electron0zero
* [CHANGE] **BREAKING CHANGE** Change the AWS Lambda serverless build tooling output from "main" to "bootstrap". Refer to https://aws.amazon.com/blogs/compute/migrating-aws-lambda-functions-from-the-go1-x-runtime-to-the-custom-runtime-on-amazon-linux-2/ for migration steps [#3852](https://github.com/grafana/tempo/pull/3852) (@zatlodan)
* [CHANGE] Add throughput and SLO metrics in the tags and tag values endpoints [#4148](https://github.com/grafana/tempo/pull/4148) (@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.
* [CHANGE] TraceByID: don't allow concurrent_shards greater than query_shards. [#4074](https://github.com/grafana/tempo/pull/4074) (@electron0zero)
* [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)
* [CHANGE] **BREAKING CHANGE** Migrate from OpenTracing to OpenTelemetry instrumentation. Removed the `use_otel_tracer` configuration option.

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 1.23.3 [#4146](https://github.com/grafana/tempo/pull/4146) [#4147](https://github.com/grafana/tempo/pull/4147) [#4380](https://github.com/grafana/tempo/pull/4380) (@javiermolinar @mdisibio)

* [CHANGE] Tighten file permissions [#4251](https://github.com/grafana/tempo/pull/4251) (@zalegrala)
* [CHANGE] Drop max live traces log message and rate limit trace too large. [#4418](https://github.com/grafana/tempo/pull/4418) (@joe-elliott)
* [CHANGE] Update the Open-Telemetry dependencies to v0.116.0 [#4466](https://github.com/grafana/tempo/pull/4466) (@yvrhdn)
* [CHANGE] Replace `cespare/xxhash` with `cespare/xxhash/v2` [#4485](https://github.com/grafana/tempo/pull/4485) (@Juneezee)
**BREAKING CHANGE** After this update the Open-Telemetry Collector receiver will connect to `localhost` instead of all interfaces `0.0.0.0`.
Due to this, Tempo installations running inside Docker have to update the address they listen.
