# Release Notes

This page describes Telmai latest release notes

## v26.3.4

Release date: 2026-09-16

### Product Changes

#### Major Changes

* [Hybrid deployment model](/telmai/deployment-models/hybrid-deployment.md) — Telmai hosts the control plane while scans run on your own Spark engine in your own environment, so raw data never leaves your network. Supported on GCP Dataproc, Azure Databricks, and AWS Databricks, with additional engines planned.
* [Microsoft Fabric connector](/telmai/connect-to-data/data-connections/microsoft-fabric.md) — connect to Fabric Warehouse and Lakehouse SQL analytics endpoints, including support for SQL queries
* [Databricks Unity Catalog integration](/telmai/integrations/catalog-integration/databricks-unity-catalog.md) — read Unity Catalog metadata for monitor recommendations, available as a new catalog type
* [Write-back to Actian Data Intelligence](/telmai/integrations/catalog-integration/zeenea.md#writing-results-back-to-actian-data-intelligence) — publish data quality scores and incident details into the catalog's native data quality section on scan completion

#### General Improvements

* [API keys are now supported at user scope](/telmai/api-reference/authentication-api/api-keys.md#key-scope) — any user can create a key for themselves through the new `auth/api_keys` endpoints, which take no tenant parameter. Key creation was previously restricted to tenant administrators, and the tenant-scoped `auth/{tenant}/apiKeys` endpoints are now deprecated. Existing keys continue to work.

#### Bug Fixes

* General fixes and improvements

#### Deprecations

* The Statistics page has reached end of life. Use the [Asset Manager](/telmai/connect-to-data/managing-assets.md) page instead.

{% 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.
