+## 1.6.0
+
+**Release date:** 2025-05-27
+
+This minor release promotes the OCIRepository API to GA, and comes with new features,
+improvements and bug fixes.
+
+### OCIRepository
+
+The `OCIRepository` API has been promoted from `v1beta2` to `v1` (GA).
+The `v1` API is backwards compatible with `v1beta2`.
+
+OCIRepository API now supports object-level workload identity by setting
+`.spec.provider` to one of `aws`, `azure`, or `gcp`, and setting
+`.spec.serviceAccountName` to the name of a service account in the same
+namespace that has been configured with appropriate cloud permissions.
+For this feature to work, the controller feature gate
+`ObjectLevelWorkloadIdentity` must be enabled. See a complete guide
+[here](https://fluxcd.io/flux/integrations/).
+
+OCIRepository API now caches registry credentials for cloud providers
+by default. This behavior can be disabled or fine-tuned by adjusting the
+token cache controller flags (see [docs](https://fluxcd.io/flux/components/source/options/)).
+The token cache also exposes metrics that are documented
+[here](https://fluxcd.io/flux/monitoring/metrics/#controller-metrics).
+
+### GitRepository
+
+GitRepository API now supports sparse checkout by setting a list
+of directories in the `.spec.sparseCheckout` field. This allows
+for optimizing the amount of data fetched from the Git repository.
+
+GitRepository API now supports mTLS authentication for HTTPS Git repositories
+by setting the fields `tls.crt`, `tls.key`, and `ca.crt` in the `.data` field
+of the referenced Secret in `.spec.secretRef`.
+
+GitRepository API now caches credentials for non-`generic` providers by default.
+This behavior can be disabled or fine-tuned by adjusting the
+token cache controller flags (see [docs](https://fluxcd.io/flux/components/source/options/)).
+The token cache also exposes metrics that are documented
+[here](https://fluxcd.io/flux/monitoring/metrics/#controller-metrics).
+
+### General updates
+
+In addition, the Kubernetes dependencies have been updated to v1.33 and
+various other controller dependencies have been updated to their latest
+version. The controller is now built with Go 1.24.
