 - Only extract span metrics / tags when they are needed. ([#2907](https://github.com/getsentry/relay/pull/2907), [#2923](https://github.com/getsentry/relay/pull/2923), [#2924](https://github.com/getsentry/relay/pull/2924))
 - Normalize metric resource identifiers in `event._metrics_summary` and `span._metrics_summary`. ([#2914](https://github.com/getsentry/relay/pull/2914))
 - Validate error_id and trace_id vectors in replay deserializer. ([#2931](https://github.com/getsentry/relay/pull/2931))
+- Add a data category for indexed spans. ([#2937](https://github.com/getsentry/relay/pull/2937))

 - This release requires Python 3.9 or later. There are no intentionally breaking changes included in this release, but we stopped testing against Python 3.8.
 - Normalize event timestamps before validating them, fixing cases where Relay would drop valid events with reason "invalid_transaction". ([#2878](https://github.com/getsentry/relay/pull/2878))
 - Normalize error and trace-ids. Values must be valid UUIDs. ([#2931](https://github.com/getsentry/relay/pull/2931))
+- Add a data category for indexed spans. ([#2937](https://github.com/getsentry/relay/pull/2937))
