 # Changelog
 
+## 0.9.0
+
+**Release date:** 2021-03-26
+
+This prerelease comes with a breaking change to the leader election ID
+from `5b6ca942.fluxcd.io` to `helm-controller-leader-election`
+to be more descriptive. This change should not have an impact on most
+installations, as the default replica count is `1`. If you are running
+a setup with multiple replicas, it is however advised to scale down
+before  upgrading.
+
+To ease debugging wait timeout errors, the last 5 deduplicated log lines
+from Helm are now recorded in the status conditions and events of the
+`HelmRelease`.
+
+To track the origin of resources that are created by a Helm operation
+performed by the controllers, they are now labeled with
+`helm.toolkit.fluxcd.io/name` and `helm.toolkit.fluxcd.io/namespace`
+using a builtin post render.
+
+The suspended status of resources is now recorded to a
+`gotk_suspend_status` Prometheus gauge metric.
+

+* Capture and expose debug (log) information on release failure
