### [`v2.2.3`](https://github.com/fluxcd/flux2/releases/tag/v2.2.3)

[Compare Source](fluxcd/flux2@v2.2.2...v2.2.3)

#### Highlights

Flux v2.2.3 is a patch release which comes with various fixes and improvements. Users are encouraged to upgrade for the best experience.

:bulb: For upgrading to Flux v2.2, please see [the procedure documented in 2.2.0](https://github.com/fluxcd/flux2/releases/tag/v2.0.0).

This release updates the Kubernetes dependencies to v1.28.6 and various other dependencies to their latest version to patch upstream CVEs.

All controllers are built with Go 1.21.6 using Alpine Linux 3.19.1 base image.

> \[!NOTE]
> Due to breaking changes in [Helm v3.14.0](https://github.com/helm/helm/releases/tag/v3.14.0), the helm-controller version included in this patch release comes with Helm SDK v3.13.3.
> A preview build of the helm-controller with the latest Helm SDK is available at [helm-controller#879](fluxcd/helm-controller#879).

Fixes:

-   Reconciling empty directories and directories without Kubernetes manifests no longer results in an error. This regressing bug was introduced with the kustomize-controller upgrade to Kustomize v5.3 and has been fixed in this patch release.
-   The regression due to which `Roles` and `ClusterRoles` with aggregated roles were continuous reconciled by kustomize-controller has been fixed.
-   Fix the Git revision displaying when notification-controller sends alerts to Grafana.
-   The HelmRelease status reporting has been improved by ensuring that the stale failure conditions get updated after failure recovery.

See the components changelog for a full list of bug fixes.
