### Release Notes

<details>
<summary>fluxcd/flux2 (fluxcd/flux2)</summary>

### [`v2.1.0`](https://github.com/fluxcd/flux2/releases/tag/v2.1.0)

[Compare Source](fluxcd/flux2@v2.0.1...v2.1.0)

#### Highlights

Flux v2.1.0 is a feature release. Users are encouraged to upgrade for the best experience.

The [Flux APIs](#api-changes) were extended with new opt-in features in a backwards-compatible manner.

The Flux Git capabilities have been improved with support for Git push options, Git refspec, Gerrit, HTTP/S and SOCKS5 proxies.

The Flux alerting capabilities have been extended with [Datadog](https://fluxcd.io/flux/components/notification/provider/#pagerduity) support.

The Flux controllers come with performance improvements when reconciling Helm repositories with large indexes (80% memory reduction), and when reconciling Flux Kustomizations with thousands of resources (x4 faster server-side apply). The load distribution has been improved when reconciling Flux objects in parallel to reduce CPU and memory spikes.

:heart: Big thanks to all the Flux contributors that helped us with this release!

#### Deprecations

Flux v2.1.0 comes with support for Kubernetes TLS Secrets when referring to secrets containing TLS certs, and deprecates the usage of `caFile`, `keyFile` and `certFile` keys.

For more details about the TLS changes please see the [Kubernetes TLS Secrets section](#kubernetes-tls-secrets).

Flux v2.1.0 comes with major improvements to the Prometheus monitoring stack. Starting with this version, Flux is leveraging the `kube-state-metrics` CRD exporter to report metrics containing rich information about Flux reconciliation status e.g. Git revision, Helm chart version, OCI artifacts digests, etc. The `gotk_reconcile_condition` metrics was deprecated in favor of the `gotk_resource_info`.

For more details about the new monitoring stack please see the [Flux Prometheus metrics documentation](https://fluxcd.io/flux/monitoring/metrics) and the [flux2-monitoring-example repository](https://github.com/fluxcd/flux2-monitoring-example).

#### API changes

##### GitRepository v1

The [GitRepository](https://fluxcd.io/flux/components/source/gitrepositories/) API was extended with the following fields:

-   `.spec.proxySecretRef.name` is an optional field used to specify the name of a Kubernetes Secret that contains the HTTP/S or SOCKS5 proxy settings.
-   `.spec.verify.mode` now support one of the following values `HEAD`, `Tag`, `TagAndHEAD`.

##### Kustomization v1

The [Kustomization](https://fluxcd.io/flux/components/kustomize/kustomization/) API was extended with two apply policies `IfNotPresent` and `Ignore`.

Changing the apply behaviour for specific Kubernetes resources, can be done using the following annotations:

| Annotation                          | Default    | Values                                                         | Role            |
|-------------------------------------|------------|----------------------------------------------------------------|-----------------|
| `kustomize.toolkit.fluxcd.io/ssa`   | `Override` | - `Override`<br/>- `Merge`<br/>- `IfNotPresent`<br/>- `Ignore` | Apply policy    |
| `kustomize.toolkit.fluxcd.io/force` | `Disabled` | - `Enabled`<br/>- `Disabled`                                   | Recreate policy |
| `kustomize.toolkit.fluxcd.io/prune` | `Enabled`  | - `Enabled`<br/>- `Disabled`                                   | Delete policy   |

The `IfNotPresent` policy instructs the controller to only apply the Kubernetes resources if they are not present on the cluster.
This policy can be used for Kubernetes `Secrets` and `ValidatingWebhookConfigurations` managed by cert-manager,
where Flux creates the resources with fields that are later on mutated by other controllers.

##### ImageUpdateAutomation v1beta1

The [ImageUpdateAutomation](https://fluxcd.io/flux/components/image/imageupdateautomations/) was extended with the following fields:

-   `.spec.git.push.refspec` is an optional field used to specify a Git refspec used when pushing commits upstream.
-   `.spec.git.push.options` is an optional field used to specify the Git push options to be sent to the Git server when pushing commits upstream.

##### Kubernetes TLS Secrets

All the Flux APIs that accept TLS data have been modified to adopt Secrets of type
`kubernetes.io/tls`. This includes:

-   **HelmRepository**: The field `.spec.secretRef` has been deprecated in favor of a new field [`.spec.certSecretRef`](https://fluxcd.io/flux/components/source/helmrepositories/#cert-secret-reference).
-   **OCIRepository**: Support for the `caFile`, `keyFile` and `certFile` keys in the Secret specified in [`.spec.certSecretRef`](https://fluxcd.io/flux/components/source/ocirepositories/#cert-secret-reference) have been deprecated in favor of `ca.crt`, `tls.key` and `tls.crt`.
-   **ImageRepository**: Support for the`caFile`, `keyFile` and `certFile` keys in the Secret specified in [`.spec.certSecretRef`](https://fluxcd.io/flux/components/source/imagerepositories/#cert-secret-reference) have been deprecated in favor of `ca.crt`, `tls.key` and `tls.crt`.
-   **GitRepository**: CA certificate can now be provided in the Secret specified in `.spec.secretRef` using the `ca.crt` key, which takes precedence over the `caFile` key.

#### Upgrade procedure

Upgrade Flux from `v2.0.x` to `v2.1.0` either by [rerunning bootstrap](https://fluxcd.io/flux/installation/#bootstrap-upgrade) or by using the [Flux GitHub Action](https://github.com/fluxcd/flux2/tree/main/action).

To upgrade Flux from `v0.x` to `v2.1.0` please follow the [Flux GA upgrade procedure](https://github.com/fluxcd/flux2/releases/tag/v2.0.0#upgrade).

#### Kubernetes compatibility

This release is compatible with the following Kubernetes versions:

| Kubernetes version | Minimum required |
|--------------------|------------------|
| `v1.25`            | `>= 1.25.0`      |
| `v1.26`            | `>= 1.26.0`      |
| `v1.27`            | `>= 1.27.1`      |
| `v1.28`            | `>= 1.28.0`      |

Note that Flux may work on older versions of Kubernetes e.g. 1.21, but we don't recommend running end-of-life versions in production nor do we offer support for these versions.
