 **Internal**:
 
 - Emit the `quantity` field for outcomes of events. This field describes the total size in bytes for attachments or the event count for all other categories. A separate outcome is emitted for attachments in a rejected envelope, if any, in addition to the event outcome. ([#942](https://github.com/getsentry/relay/pull/942))
+- Add experimental metrics ingestion without bucketing or pre-aggregation. ([#948](https://github.com/getsentry/relay/pull/948))
+- Skip serializing some null values in frames interface. ([#944](https://github.com/getsentry/relay/pull/944))
 - Add experimental metrics ingestion with bucketing and pre-aggregation. ([#948](https://github.com/getsentry/relay/pull/948), [#952](https://github.com/getsentry/relay/pull/952), [#958](https://github.com/getsentry/relay/pull/958), [#966](https://github.com/getsentry/relay/pull/966), [#969](https://github.com/getsentry/relay/pull/969))
 - Change HTTP response for upstream timeouts from 502 to 504. ([#859](https://github.com/getsentry/relay/pull/859))
 - Add rule id to outcomes coming from transaction sampling. ([#953](https://github.com/getsentry/relay/pull/953))
