# Version 1.3 release notes

The Tempo team is excited to announce the release of Tempo 1.3.

## Features and enhancements

- **Search** In addition to the existing search of recent traces, support has been added to search traces in the backend store. Refer to [Tempo search](../../../introduction/tempo-in-grafana/) for details.
- **Improve ring functionality** The compactor ring automatically forgets about unhealthy ring members.
- **Protect instances from very large traces** The ingester keeps track of traces that exceed the configured maximum size, extending protection from very large traces to after the traces are flushed to disk.
- **Expose additional metrics** These new metrics are exposed:
  
  - `tempo_limits_overrides`
  - `tempo_limits_defaults`
  - `tempo_ingester_live_traces`
  - `tempodb_compaction_outstanding_blocks`
- **Azure credentials may be set in the environment** Instead of setting values in the configuration, environment variables may specify `AZURE_STORAGE_ACCOUNT` and `AZURE_STORAGE_KEY`.

## Upgrade considerations

When upgrading to Tempo v1.3, be aware of these breaking changes:

- [PR 1142](https://github.com/grafana/tempo/pull/1142): The OpenTelemetry Collector’s GRPC receiver’s default port changed from 55680 to 4317.
- [PR 1174](https://github.com/grafana/tempo/pull/1174): Configuration option `querier.search_max_result_limit` is renamed to `query_frontend.search.max_result_limit`. Configuration option `querier.search_default_result_limit` is renamed to `query_frontend.search.default_result_limit`.
- [PR 1173](https://github.com/grafana/tempo/pull/1173): Removed the deprecated `Push` method from `tempopb.Pusher`.

## Known issues

- Grafana does not yet support the `tempoBackendSearch` feature toggle to enable searches in the backend datastore.
