### Flow

#### OpenTelemetry Metrics Support in Apica Telemetry Pipeline is now GA.

* **OpenTelemetry Metrics in Telemetry Pipelines**:\
  Apica Flow now fully supports **receiving and forwarding OpenTelemetry (OTLP)-compatible metrics** within Apica telemetry pipelines.
* **OTLP Metrics Endpoint**:\
  You can now ingest metrics through the `/v1/metrics` OTLP-compatible endpoint.
* **Flexible Storage Options**:\
  Configure whether metrics are sent to internal Ascent Prometheus storage or forwarded externally to another OTLP compatible metric storage OR archive to an external object store.
* **OTLP Metrics and Logs Forwarders** to compatible external systems.

***

### Pipelines and Rules Enhancements

#### New Functions

* **`flatten(input: object)`**:\
  Flattens nested JSON structures into simple key-value pairs.
* **`unflatten(input: object)`**:\
  Reconstructs nested JSON objects from flattened structures, enabling full roundtrip transformations.

This release further strengthens Apica Flow’s telemetry capabilities, giving you more flexibility, deeper observability, and better control over your pipelines and metrics.
