 # Changelog
 
+## v2.4.0 (Unreleased)
+
+### Web Terminal In Argo CD UI
+
+Feature enables engineers to start a shell in the running application container without leaving the web interface. Just find the required Kubernetes
+Pod using the Application Details page, click on it and select the Terminal tab. The shell starts automatically and enables you to execute the required
+commands, and helps to troubleshoot the application state.
+
+### Access Control For Pod Logs & Web Terminal
+
+Argo CD is used to manage the critical infrastructure of multiple organizations, which makes security the top priority of the project. We've listened to
+your feedback and introduced additional access control settings that control access to Kubernetes Pod logs and the new Web Terminal feature.
+
+#### Known UI Issue for Pod Logs Access
+
+Currently, upon pressing the "LOGS" tab in pod view by users who don't have an explicit allow get logs policy, the red "unable to load data: Internal error" is received in the bottom of the screen, and "Failed to load data, please try again" is displayed.
+
+### OpenTelemetry Tracing Integration
+
+The new feature allows emitting richer telemetry data that might make identifying performance bottlenecks easier. The new feature is available for argocd-server
+and argocd-repo-server components and can be enabled using the --otlp-address flag.
+
+### Power PC and IBM Z Support
+
+The list of supported architectures has been expanded, and now includes IBM Z (s390x) and PowerPC (ppc64le). Starting with the v2.4 release the official quay.io
+repository is going to have images for amd64, arm64, ppc64le, and s390x architectures.
+
+### Other Notable Changes
+
+Overall v2.4 release includes more than 300 hundred commits from nearly 90 contributors. Here is a short sample of the contributions:
+
+* Enforce the deployment to remote clusters only
+* Native support of GCP authentication for GKE
+* Secured Redis connection
+* ApplicationSet Gitea support
+
+
+## v2.3.3 (2022-03-29)
+
+- fix: prevent excessive repo-server disk usage for large repos (#8845) (#8897)
+- fix: Set QPS and burst rate for resource ops client (#8915)
+
+## v2.3.2 (2022-03-22)
+
+- fix: application resource APIs must enforce project restrictions
+
+## v2.3.1 (2022-03-10)
+
+- fix: Retry checkbox unchecked unexpectedly; Sync up with YAML (#8682) (#8720)
+- chore: Bump stable version of application set addon (#8744)
+- fix: correct jsonnet paths resolution (#8721)
+- fix(ui): Applications page incorrectly resets to tiles view. Fixes #8702 (#8718)
+
+## v2.3.0 (2022-03-05)
+
+### Argo CD ApplicationSet and Notifications are now part of Argo CD
+
+Two popular [Argoproj Labs](https://github.com/argoproj-labs) projects [Argo CD ApplicationSet](https://github.com/argoproj/applicationset) and
+[Argo CD Notifications](https://github.com/argoproj-labs/argocd-notifications) are now part of Argo CD! The default Argo CD installation manifests now
+bundle both projects out of the box. Going forward you can expect more tightened integration of these projects into Argo CD.
+
+### New sync and diff strategies
+
+Users can now configure the Application resource to instruct Argo CD to consider the ignore difference setup during the sync process.
+In order to do so, add the new sync option RespectIgnoreDifferences=true in the Application resource. Once the sync option is added,
+Argo CD won't change ignored fields during the syncing process.
+
+Configuring ignored fields is also easier now. Instead of listing fields one by one users can now leverage the 
+managedFields metadata to instruct Argo CD about trusted managers and automatically ignore any fields owned by them. A new diff customization
+(managedFieldsManagers) is now available allowing users to specify managers the application should trust and to ignore all fields owned by those managers.
+Read more about these changes at [New sync and diff strategies in ArgoCD](https://blog.argoproj.io/new-sync-and-diff-strategies-in-argocd-44195d3f8b8c) blog post.
+
+### ARM Images
+
+An officially supported ARM 64 image is now available. Enjoy running Argo CD on your Raspberry Pi! Additionally, the image size was reduced by nearly ~50%
+and is only 200MB now. The ARM version of `argocd` CLI is also available and published as a Github release artifact.
+
+### Compact Tree View And Click Application Navigation
+
+The application details page now supports compact application resources tree visualization. Using the "Group Nodes" button, you can collapse the similar resources
+into a single group node to remove the clutter and make it easier to understand the state of application resources. You still can get detailed information about the collapsed resources by clicking on the group node. The list of collapsed resources will be available in a sliding panel. Compact resource tree is still too big?
+You can use the zoom in and zoom out feature to make it smaller - or even larger!
+
+You no longer need to move back and forth between the application details page and the application list page. Instead you can navigate directly to the required application by clicking the search icon in the application details page title.
+
+### Upgraded Config Management Tools
+
+Both bundled Helm and Kustomize binaries have been upgraded to the latest versions. Kustomize has been upgraded from 4.2.0 to 4.4.1 and Helm has been upgraded from 3.7.1 to 3.8.0.
+

+# How the Cluster Decision Resource generator works for clusterDecisionResource
+1. The Cluster Decision Resource generator reads a configurable status format:
+```yaml
+status:
+  clusters:
+  - name: cluster-01
+  - name: cluster-02
+```
+This is a common status format.  Another format that could be read looks like this:
+```yaml
+status:
+  decisions:
+  - clusterName: cluster-01
+    namespace: cluster-01
+  - clusterName: cluster-02
+    namespace: cluster-02
+```
+2. Any resource that has a list of key / value pairs, where the value matches ArgoCD cluster names can be used.
+3. The key / value pairs found in each element of the list will be available to the template. As well, `name` and `server` will still be available to the template.
+4. The Service Account used by the ApplicationSet controller must have access to `Get` the resource you want to retrieve the duck type definition from
+5. A configMap is used to identify the resource to read status of generated ArgoCD clusters from. You can use multiple resources by creating a ConfigMap for each one in the ArgoCD namespace.
+```yaml
+apiVersion: v1
+kind: ConfigMap
+metadata:
+  name: my-configmap
+data:
+  apiVersion: group.io/v1
+  kind: mykinds
+  statusListKey: clusters
+  matchKey: name
+```
+  * `apiVersion`    - This is the apiVersion of your resource
+  * `kind`          - This is the plural kind of your resource
+  * `statusListKey` - Default is 'clusters', this is the key found in your resource's status that is a list of ArgoCD clusters.
+  * `matchKey`      - Is the key name found in the cluster list, `name` and `clusterName` are the keys in the examples above.
+
+# Applying the example
+1. Connect to a cluster with the ApplicationSet controller running
+2. Edit the Role for the ApplicationSet service account, and grant it permission to `list` the `placementdecisions` resources, from apiGroups `cluster.open-cluster-management.io/v1alpha1`
+```yaml
+- apiGroups:
+  - "cluster.open-cluster-management.io/v1alpha1"
+  resources:
+  - placementdecisions
+  verbs:
+  - list
+```
+3. Apply the following controller and associated ManagedCluster CRD's:
+https://github.com/open-cluster-management/placement
+4. Now apply the PlacementDecision and an ApplicationSet:
+```bash
+kubectl apply -f ./placementdecision.yaml
+kubectl apply -f ./configMap.yaml
+kubectl apply -f ./ducktype-example.yaml
+```
+5. For now this won't do anything until you create a controller that populates the `Status.Decisions` array.
