{% hint style="warning" %}
**Upgrade of External Secrets**\
\
If you're using  [External Secrets](https://external-secrets.io/), please upgrade your Helm charts to version 0.17.0. This update includes a breaking change with the `apiVersion`, transitioned from `v1beta1` to `v1`. For more details, check the [release notes](https://github.com/external-secrets/external-secrets/releases/tag/helm-chart-0.17.0). This needs to be done before upgrading to the new binaries.
{% endhint %}

{% hint style="warning" %}
**GCP Permission Changes**

To improve the management of keys generated for tenant service accounts, the `TelmaiServicesRunner` requires three additional IAM permissions:

* `iam.serviceAccountKeys.get`
* `iam.serviceAccountKeys.list`
* `iam.serviceAccountKeys.delete`

These permissions will help ensure better control and cleanup of service account keys.

Not adding permissions does not affect running applications.
