# Version 2.9 release notes

Grafana Labs is excited to announce the release of Grafana Enterprise Metrics (GEM) 2.9, which is built on top of Grafana Mimir 2.9.

GEM 2.9 inherits all of the features, enhancements, and bugfixes that are in the Grafana Mimir 2.9 release. Given this, it’s best to start with the [Grafana Mimir 2.9 release notes](/docs/mimir/latest/release-notes/v2.9/).

## Features and enhancements

- The admin API now has experimental support for audit logging of requests. More information is available in [the documentation](/docs/enterprise-metrics/latest/api/admin-api/audit-logging/).
- We’ve added `arm64` Docker images for GEM to enable organizations to run GEM on ARM-based machines. These images are available on the [Enterprise Metrics Docker Registry](https://hub.docker.com/r/grafana/enterprise-metrics/tags), as described on the [Grafana Enterprise Metrics Downloads page](/docs/enterprise-metrics/latest/get-started/download-gem/#v290----june-22nd-2023). In our own initial internal tests, highlighted in our [GrafanaCon 2023 presentation at 15:55](/about/events/grafanacon/2023/session/tsdb-mimir-recap/), we saw a cost reduction of 20% when comparing GEM on ARM to GEM on x86 with no noticeable performance difference.

## Upgrade considerations

There are no breaking changes in this release of GEM.

This release also inherits the [upgrade considerations](/docs/mimir/latest/release-notes/v2.9/#upgrade-considerations) from the Grafana Mimir 2.9 release.

After you upgrade to GEM 2.9, upgrade your [GEM plugin](/grafana/plugins/grafana-metrics-enterprise-app/) to the latest version. For more information about the most recent enhancements and bugfixes in the GEM plugin, see the [Grafana Enterprise Metrics: Changelog](/grafana/plugins/grafana-metrics-enterprise-app/?tab=changelog).
