+
+## New releases
+
+We are happy to announce the latest GA releases for Flux and Flagger.
+
+### Flux v2.1.0
+
+This new release comes with lots of new features,
+fixes, restructured documentation and performance improvements.
+Everyone is encouraged to upgrade for the best experience.
+
+The [Flux APIs](https://github.com/fluxcd/flux2/releases/tag/v2.1.0#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.
+
+In case you missed it, Flux reached General Availability in June.
+You can read the announcement
+[here](https://fluxcd.io/blog/2023/07/flux-ga/).
+
+You can now check the end-of-life(EOL) dates and support information for
+different Flux versions at https://endoflife.date/flux.
+
+#### Features
+
+- The [GitRepository API](https://fluxcd.io/flux/components/source/gitrepositories/#proxy-secret-reference)
+  has a new field `.spec.proxySecretRef` that is used for specifying proxy configuration to use
+  for all remote Git operations related to the particular object.
+- The`.spec.verify.mode` field of the [GitRepository API](https://fluxcd.io/flux/components/source/gitrepositories/#verification)
+  now accepts one of the following values `HEAD`, `Tag`, `TagAndHEAD`. These values are used to specify
+  how the Git tags and commits are verified.
+- The [server-side apply behaviour](https://fluxcd.io/flux/components/kustomize/kustomizations/#controlling-the-apply-behavior-of-resources)
+  in the kustomize-controller has been extended with two extra policies:
+  `IfNotPresent` and `Ignore`. These policies are specified with the `kustomize.toolkit.fluxcd.io/ssa`
+  annotation on the resource manifest. The `IfNotPresent` policy is useful to have Flux create an object
+  that will later be managed by another controller.
+- Support for sending notifications to [DataDog](https://fluxcd.io/flux/components/notification/providers/#datadog).
+- The [ImageUpdateAutomation API](https://fluxcd.io/flux/components/image/imageupdateautomations/#push) has two
+  new optional fields - `.spec.git.push.refspec` and `.spec.git.push.options` for to specify a refspec and push
+  options that will be used when pushing commits upstream.
+
+#### Fixes and improvements
+
+Here is a short list of features and improvements in this release:
+
+- A new flag `--concurrent-ssa` has been introduced in the kustomize-controller to set the number of concurrent
+ server-side operations that will be performed by the controller per object. This increases speed when
+ reconciling Kustomization with a considerable amount of objects.
+- Performance improvement when loading helm repositories with large indexes (up to 80% memory reduction).
+- The load distribution has been improved when reconciling Flux objects in parallel to reduce CPU and memory spikes.
+- The Installation and Monitoring sections of the Flux documentation have been restructured to make navigation
+  and locating guides easier. We are always open to receiving feedback on how we can improve the documentation.
+
+#### Deprecation
+
+- All APIs that accept TLS data have been modified to support Kubernetes TLS style secrets.
+  The keys `caFile`, `certFile` and `keyFile`  have been deprecated. For more details about the TLS changes 
+  please see the [Kubernetes TLS Secrets section](https://github.com/fluxcd/flux2/releases/tag/v2.1.0#kubernetes-tls-secrets).
+- ⚠️ Breaking changes: This release comes with breaking changes to the Flux monitoring stack (Prom+Grafana).
+  The stack now leverages the
+  [kube-state-metrics Custom Resource State metrics](https://github.com/kubernetes/kube-state-metrics/blob/main/docs/customresourcestate-metrics.md)
+  to report some Flux resource metrics. This will allow users to extend the Flux metrics with custom metadata. The
+  [monitoring configuration in the fluxcd/flux2 repository](https://github.com/fluxcd/flux2/tree/v2.1.0/manifests/monitoring#warning-deprecation-notice)
+  is now deprecated and will be removed in a future release. The new monitoring configuration is located at
+  [fluxcd/flux2-monitoring-example](https://github.com/fluxcd/flux2-monitoring-example/).
+  Please see the new monitoring guide https://fluxcd.io/flux/monitoring for more information.
+
+#### Upgrade
+
+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).
+
+To 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).
+
+You can take a look at the [changelog](https://github.com/fluxcd/flux2/releases/tag/v2.1.0) for the full list of changes.
+
+❣️Big thanks to all the Flux contributors who helped us with this release!
+
+#### Flux Grafana Dashboards
+
+The Flux monitoring stack comes with two dashboards
+for easy visualization of Flux controllers and resource metrics. 
+You can follow this [link](https://github.com/fluxcd/flux2-monitoring-example)
+to learn how to set it up.

+
+
+### Flagger v1.33.0
+
+This release fixes bugs related to the Canary lifecycle. The `confirm-traffic-increase` webhook
+is no longer called if the Canary is in the `WaitingPromotion` phase. Furthermore, a bug which
+caused downtime when initializing the Canary deployment has been fixed. Also, a bug in the
+`request-duration` metric for Traefik which assumed the result to be in milliseconds
+instead of seconds has been addressed.
+
+The loadtester now also supports running `kubectl` commands.
+
+Please see the [changelog](https://github.com/fluxcd/flagger/blob/main/CHANGELOG.md#1310) for the full changes.

+## Flux Ecosystem
+
+### Terraform-controller
+
+The ecosystem is buzzing with news about the licensing changes to Hashicorp’s open-source projects
+including Terraform. Weaveworks has released a
+[statement](https://www.weave.works/blog/statement-for-terraform-hashicorp-license-changes)
+on this and the impact on the tf-controller.
+
+### VS Code GitOps Extension
+
+Significant performance upgrades and code refactoring has been introduced with VS Code GitOps Tools
+extension version 0.25.0. Previously cluster metadata was loaded using `kubectl get` commands.
+Now, a new javascript client is also used which permits faster loading and real-time watching of cluster resources.
+`kubectl proxy` is executed in the background for the new client. Rendering of resource treeviews has been reworked
+to minimise data reloading, to maintain collapsible state and to allow visualising resource errors grouped
+by namespaces. Timeout settings were added and bad cluster connections should no longer slow down Clusters treeview rendering.
+
+UI refinements and bug fixes for the new client are ongoing. The most up-to-date UI features can be previewed by
+selecting “Install Pre-Release Version” in the VS Code Extension Browser.
+
+## Flux Fun Fact!
+
+Did you know …
+🔒 Flux is designed with security in mind: Pull vs. Push,
+least amount of privileges, adherence to Kubernetes security
+policies and tight integration with security tools and
+best-practices. Read more about our security considerations.
