# 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

## v2.3.0 (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.

### Project Scoped repositories and clusters

The project scoped repositories and clusters is a feature that simplifies registering the repositories and cluster credentials.
Instead of requiring operators to set up in advance all clusters and git repositories that can be used, developers can now do
this on their own in a self-service manner.

### Config Management Plugins V2

The Config Management Plugins V2 is set of enhancement of the existing config management plugins feature.
The list includes improved installation experience, ability to package plugin into a separate image and
improved plugin manifests discovery.

### Resource tracking

Argo CD has traditionally tracked the resources it manages by the well-known "app.kubernetes.io/instance" property.
While using this property works ok in simple scenarios, it also has several limitations. ArgoCD now allows you to use
a new annotation (argocd.argoproj.io/tracking-id) for tracking your resources. Using this annotation is a much more flexible approach
as there are no conflicts with other Kubernetes tools, and you can easily install multiple Argo CD instances on the same clusters.

### Argo CD Core

Argo CD Core - lightweight Argo CD distribution that packages only core GitOps features and relies
on Kubernetes API/RBAC to power UI and CLI.

### Core Features

* The synchronization process became much much faster and requires significantly less memory.
* An additional caching that ensures that each repository's target revisions are queried only once per
  reconciliation cycle. This dramatically reduces the number of Git requests.
* Improved Diffing Customizations: use JQ path expressions to exclude required fields from the diffing.
* Health assessment support for new CRDs: introduced health assessment of CRDs from trident.netapp.io,
  elasticsearch.k8s.elastic.co, cluster.x-k8s.io, and minio.min.io API groups.

### Improved Settings

A set of changes had been implemented to simplify configuring Argo CD.

* Simplified Repository Registration: you no longer need to modify the argocd-cm ConfigMap to register a
  new Git or Helm repository.
* Enhanced Resource Customizations: the resource.customizations key has been deprecated in favor of
  a separate ConfigMap key per resource.
* Reference secret values from any Kubernetes secret: starting v2.1 you can use sensitive data stored in 
  any Kubernetes secret to configure Argo CD.
* Simplify parametrization of Argo CD server processes: an additional optional ConfigMap argocd-cmd-params-cm
  has been introduced.

### Refreshed User Interface

* Enhanced and more consistent filters on Applications List and Applications Details pages.
* Status bar on the Application List page.
* The redesigned search box on the Application List page and more.

### The argocd-util CLI deprecation

The argocd CLI and now available under argocd admin subcommand.

## v2.0.0 (2021-04-07)

> [Upgrade instructions](./docs/operator-manual/upgrading/1.8-2.0.md)

### Pods View

Pods View is particularly useful for applications that have hundreds of pods. Instead of visualizing all Kubernetes
resources for the application, it only shows Kubernetes pods and closely related resources. The Pods View supports
grouping related resources by Parent Resource, Top Level Parent, or by Node. Each way of grouping solves a particular
use case. For example grouping by Top Level Parent allows you to quickly find how many pods your application is running
and which resources created them. Grouping by Node allows to see how Pods are spread across the nodes and how many
resources they requested.


### Logs Viewer

Argo CD provides a way to see live logs of pods, which is very useful for debugging and troubleshooting. In the v2.0
release, the log visualization has been rewritten to support pagination, filtering, the ability to disable/enable log
streaming, and even a dark mode for terminal lovers. Do you want to see aggregated logs of multiple deployment pods?
Not a problem! Just click on the parent resource such as Deployment, ReplicaSet, or StatefulSet and navigate
to the Logs tab.

### Banner Feature

Want to notify your Argo CD users of upcoming changes? Just specify the notification message and optional URL using the
`ui.bannercontent` and `ui.bannerurl` attributes in the `argocd-cm` ConfigMap. 

### Core Features

* The new sync option `PrunePropagationPolicy=background` allows using background deletion during syncing
* New application finalizer `resources-finalizer.argocd.argoproj.io:background` allows using background deletion when the application is deleted
* The new sync option `ApplyOutOfSyncOnly=true` allows skipping syncing resources that are already in the desired state.
* The new sync option `PruneLast=true` allows deferring resource pruning until the last synchronization phase after all other resources are synced and healthy.

### The argocd-util CLI

Argo CD Util is a CLI tool that contains useful commands for operators who manage Argo CD. Starting from this release
the Argo CD Utility is published with every Argo CD release as a Homebrew installation.

## v1.8.7 (2021-02-26)

### Important note
This release fixed a regression regarding which cluster resources are permitted on the AppProject level.
Previous to this fix, after #3960 has been merged, all cluster resources were allowed on project level when neither of
the allow or deny lists was defined. However, the correct behavior is to block all resources in this case.

If you have Projects with empty allow and deny lists, but want the associated applications be able to sync cluster
resources, you will have to adapt your cluster resources allow lists to explicitly allow the resources.

## v1.8.0 (2020-12-09)

### Mono-Repository Improvements

Enhanced performance during manifest generation from mono-repository - the repository that represents the
desired state of the whole cluster and contains hundreds of applications. The improved argocd-repo-server
now able to concurrently generate manifests from the same repository and for the same commit SHA. This
might provide 10x performance improvement of manifests generation.

### Annotation Based Path Detection

The feature that allows specifying which source repository directories influence the application manifest generation
using the `argocd.argoproj.io/manifest-generate-paths` annotation. The annotation improves the Git webhook handler
behavior. The webhook avoids related applications reconciliation if no related files have been changed by the Git commit
and even allows to skip manifests generation for new commit by re-using generation manifests for the previous commit.

### Horizontal Controller Scaling

This release allows scaling the `argocd-application-controller` horizontally. This allows you to manage as many Kubernetes clusters
as needed using a single Argo CD instance.

## New Core Functionality Features

Besides performance improvements, Argo CD got a lot of usability enhancements and new features:

* Namespace and CRD creation [#4354](https://github.com/argoproj/argo-cd/issues/4354)
* Unknown fields of built-in K8S types [#1787](https://github.com/argoproj/argo-cd/issues/1787)
* Endpoints Diffing [#1816](https://github.com/argoproj/argo-cd/issues/1816)
* Better compatibility with Helm Hooks [#1816](https://github.com/argoproj/argo-cd/issues/1816)
* App-of-Apps Health Assessment [#3781](https://github.com/argoproj/argo-cd/issues/3781)

## Global Projects

This release makes it easy to manage an Argo CD that has hundreds of Projects. Instead of duplicating the same organization-wide rules in all projects
you can put such rules into one project and make this project “global” for all other projects. Rules defined in the global project are inherited by all
other projects and therefore don’t have to be duplicated. The sample below demonstrates how you can create a global project and specify which project should
inherit global project rules using Kubernetes labels. 

## User Interface Improvements

The Argo CD user interface is an important part of a project and we keep working hard on improving the user experience. Here is an incomplete list of implemented improvements:

* Improved Applications Filters [#4622](https://github.com/argoproj/argo-cd/issues/4622)
* Git tags and branches autocompletion [#4713](https://github.com/argoproj/argo-cd/issues/4713)
* Project Details Page [#4400](https://github.com/argoproj/argo-cd/issues/4400)
* New version information panel [#4376](https://github.com/argoproj/argo-cd/issues/4376)
* Progress Indicators [#4411](https://github.com/argoproj/argo-cd/issues/4411)
* External links annotations [#4380](https://github.com/argoproj/argo-cd/issues/4380) and more!

## Config Management Tools Enhancements

* OCI Based Repositories [#4018](https://github.com/argoproj/argo-cd/issues/4018)
* Configurable Helm Versions [#4111](https://github.com/argoproj/argo-cd/issues/4111)

## v1.7.0 (2020-08-24)

### GnuPG Signature Verification

The feature allows to only sync against commits that are signed in Git using GnuPG. The list of public 
GPG keys required for verification is configured at the system level and can be managed using Argo CD CLI or Web user interface.
The keys management is integrated with Argo CD SSO and access control system (e.g. `argocd gpg add --from <path-to-key>`)

The signature verification is enabled on the project level. The ApplicationProject CRD has a new signatureKeys field that includes
a list of imported public GPG keys. Argo CD will verify the commit signature by these keys for every project application.

### Cluster Management Enhancements

The feature allows using the cluster name instead of the URL to specify the application destination cluster.
Additionally, the cluster CLI and Web user interface have been improved. Argo CD operators now can view and edit cluster
details using the Cluster Details page. The page includes cluster settings details as well as runtime information such
as the number of monitored Kubernetes resources.

### Diffing And Synchronization Usability

* **Diffing logic improvement** Argo CD performs client-side resource diffing to detect deviations and present detected
differences in the UI and CLI. The 1.7 release aligns a comparison algorithm with server-side Kubernetes implementation
and removes inaccuracies in some edge cases.

* **Helm Hooks Compatibility** The improvement removes the discrepancy between the way how Argo CD and Helm deletes
hooks resources. This significantly improves the compatibility and enables additional use cases.

* **Namespace Auto-Creation** With a new option for applications Argo CD will ensure that namespace specified as the
application destination exists in the destination cluster. 

* **Failed Sync Retry** This feature enables retrying of failed synchronization attempts during both manually-triggered
and automated synchronization.

### Orphaned Resources Monitoring Enhancement

The enhancement allows configuring an exception list in Orphaned Resources settings to avoid false alarms.

### GitOps Engine

As part of 1.6 release, the core Argo CD functionality has been moved into [GitOps Engine](https://github.com/argoproj/gitops-engine).
GitOps Engine is a reusable library that empowers you to quickly build specialized tools that implement specific GitOps
use cases, such as bootstrapping a Kubernetes cluster, or decentralized management of namespaces.

## v1.5.3 (2020-05-01)

This patch release introduces a set of enhancements and bug fixes. Here are most notable changes:

#### Multiple Kustomize Versions

The bundled Kustomize version had been upgraded to v3.5.4. Argo CD allows changing bundled version using
[custom image or init container](https://argoproj.github.io/argo-cd/operator-manual/custom_tools/). 
This [feature](https://argoproj.github.io/argo-cd/user-guide/kustomize/#custom-kustomize-versions)
enables bundling multiple Kustomize versions at the same time and allows end-users to specify the required version per application.

#### Custom Root Path

The feature allows accessing Argo CD UI and API using a custom root path(for example https://myhostname/argocd).
This enables running Argo CD behind a proxy that takes care of user authentication (such as Ambassador) or hosting
multiple Argo CD using the same hostname. A set of bug fixes and enhancements had been implemented to makes it easier.
Use new `--rootpath` [flag](https://argoproj.github.io/argo-cd/operator-manual/ingress/#argocd-server-and-ui-root-path-v153) to enable the feature.

### Login Rate Limiting

The feature prevents a built-in user password brute force attack and addresses the known 
[vulnerability](https://argoproj.github.io/argo-cd/security_considerations/#cve-2020-8827-insufficient-anti-automationanti-brute-force).

### Settings Management Tools

A new set of [CLI commands](https://argoproj.github.io/argo-cd/operator-manual/troubleshooting/) that simplify configuring Argo CD.
Using the CLI you can test settings changes offline without affecting running Argo CD instance and have ability to troubleshot diffing
customizations, custom resource health checks, and more.

### Other

* New Project and Application CRD settings ([#2900](https://github.com/argoproj/argo-cd/issues/2900), [#2873](https://github.com/argoproj/argo-cd/issues/2873)) that allows customizing Argo CD behavior.
* Upgraded Dex (v2.22.0) enables seamless [SSO integration](https://www.openshift.com/blog/openshift-authentication-integration-with-argocd) with OpenShift.

#### Critical security fix

This release contains a critical security fix. Please refer to the
[security document](https://argoproj.github.io/argo-cd/security_considerations/#CVE-2020-5260-possible-git-credential-leak)
for more information.

**Upgrading is strongly recommended**

## v1.4.3 (2020-04-20)

#### Critical security fix

This release contains a critical security fix. Please refer to the
[security document](https://argoproj.github.io/argo-cd/security_considerations/#CVE-2020-5260-possible-git-credential-leak)
for more information.

## v1.5.1 (2020-04-06)

#### Bug Fixes

* fix: return 401 error code if username does not exist (#3369)
* fix: Do not panic while running hooks with short revision (#3368)
* fix: Increase HAProxy check interval to prevent intermittent failures (#3356)
* fix: Helm v3 CRD are not deployed (#3345)

## v1.5.0 (2020-04-02)

#### Helm Integration Enhancements - Helm 3 Support And More

Introduced native support Helm3 charts. For backward compatibility Helm 2 charts are still rendered using Helm 2 CLI. Argo CD inspects the
Charts.yaml file and choose the right binary based on `apiVersion` value.

Following enhancement were implemented in addition to Helm 3:
* The `--api-version` flag is passed to the `helm template` command during manifest generation.
* The `--set-file` flag can be specified in the application specification.
* Fixed bug that prevents automatically update Helm chart when new version is published (#3193)

#### Better Performance and Improved Metrics

 If you are running Argo CD instances with several hundred applications on it, you should see a
 huge performance boost and significantly less Kubernetes API server load.

 The Argo CD controller Prometheus metrics have been reworked to enable a richer Grafana dashboard.
 The improved dashboard is available at [examples/dashboard.json](https://github.com/argoproj/argo-cd/blob/master/examples/dashboard.json).
 You can set `ARGOCD_LEGACY_CONTROLLER_METRICS=true` environment variable and use [examples/dashboard-legacy.json](https://github.com/argoproj/argo-cd/blob/master/examples/dashboard-legacy.json)
 to keep using old dashboard.

#### Local accounts

The local accounts had been introduced additional to `admin` user and SSO integration. The feature is useful for creating authentication
tokens with limited permissions to automate Argo CD management. Local accounts also could be used small by teams when SSO integration is overkill.
This enhancement also allows to disable admin user and enforce only SSO logins.

#### Redis HA Proxy mode

As part of this release, the bundled Redis was upgraded to version 4.3.4 with enabled HAProxy.
The HA proxy replaced the sentinel and provides more reliable Redis connection.

> After publishing 1.5.0 release we've discovered that default HAProxy settings might cause intermittent failures.
> See [argo-cd#3358](https://github.com/argoproj/argo-cd/issues/3358)

#### Windows CLI

Windows users deploy to Kubernetes too! Now you can use Argo CD CLI on Linux, Mac OS, and Windows. The Windows compatible binary is available 
in the release details page as well as on the Argo CD Help page.

#### Breaking Changes

The `argocd_app_sync_status`, `argocd_app_health_status` and `argocd_app_created_time` prometheus metrics are deprecated in favor of additional labels
to `argocd_app_info` metric. The deprecated labels are still available can be re-enabled using `ARGOCD_LEGACY_CONTROLLER_METRICS=true` environment variable.
The legacy example Grafana dashboard is available at [examples/dashboard-legacy.json](https://github.com/argoproj/argo-cd/blob/master/examples/dashboard-legacy.json).

## v1.4.2 (2020-01-24)

- fix: correctly replace cache in namespace isolation mode (#3023)

## v1.4.1 (2020-01-23)

- fix: impossible to config RBAC if group name includes ',' (#3013)

## v1.4.0 (2020-01-17)

The v1.4.0 is a stability release that brings multiple bug fixes, security, performance enhancements, and multiple usability improvements.

#### New Features

#### Security
A number of security enhancements and features have been implemented (thanks to [@jannfis](https://github.com/jannfis) for driving it! ):
* **Repository Credential Templates Management UI/CLI**. Now you can use Argo CD CLI or UI to configure
[credentials template](https://argoproj.github.io/argo-cd/user-guide/private-repositories/#credential-templates) for multiple repositories!
* **X-Frame-Options header on serving static assets**. The X-Frame-Options prevents third party sites to trick users into interacting with the application.
* **Tighten AppProject RBAC enforcement**. We've improved the enforcement of access rules specified in the
[application project](https://argoproj.github.io/argo-cd/operator-manual/declarative-setup/#projects) configuration.

#### Namespace Isolation
With the namespace isolation feature, you are no longer have to give full read-only cluster access to the Argo CD. Instead, you can give access only to selected namespaces with-in
the cluster:

```bash
argocd cluster add <mycluster> --namespace <mynamespace1> --namespace <mynamespace2>
```

This feature is useful if you don't have full cluster access but still want to use Argo CD to manage some cluster namespaces. The feature also improves performance if Argo CD is
used to manage a few namespaces of a large cluster.

#### Reconciliation Performance
The Argo CD no longer fork/exec `kubectl` to apply resource changes in the target cluster or convert resource manifest to the required manifest version. This reduces
CPU and Memory usage of large Argo CD instances.

#### Resources Health based Hook Status
The existing Argo CD [resource hooks](https://argoproj.github.io/argo-cd/user-guide/resource_hooks/) feature allows running custom logic during the syncing process. You can mark
any Kubernetes resource as a hook and Argo CD assess hook status if resource is a `Pod`, `Job` or `Argo Workflow`. In the v1.4.0 release Argo CD is going to leverage resource
[health assessment](https://argoproj.github.io/argo-cd/operator-manual/health/) to get sync hook status. This allows using any custom CRD as a sync hook and leverage custom health
check logic.

#### Manifest Generation
* **Track Helm Charts By Semantic Version**. You've been able to track charts hosted in Git repositories using branches to tags. This is now possible for Helm charts. You no longer
 need to choose the exact version, such as v1.4.0 ,instead you can use a semantic version constraint such as v1.4.* and the latest version that matches will be installed.
* **Build Environment Variables**. Feature allows config management tool to get access to app details during manifest generation via
[environment variables](https://argoproj.github.io/argo-cd/user-guide/build-environment/).
* **Git submodules**. Argo CD is going to automatically fetch sub-modules if your repository has `.gitmodules` directory.

#### UI and CLI
* **Improved Resource Tree View**. The Application details page got even prettier. The resource view was tuned to fit more resources into the screen, include more information about
each resource and don't lose usability at the same time.
* **New Account Management CLI Command**. The CLI allows to check which actions are allowed for your account: `argocd account can-i sync applications '*'`

#### Maintenance Tools
The team put more effort into building tools that help to maintain Argo CD itself:
* **Bulk Project Editing**. The `argocd-util` allows to add and remove permissions defined in multiple project roles using one command.
* **More Prometheus Metrics**. A set of additional metrics that contains useful information managed clusters is exposed by application controller.

More documentation and tools are coming in patch releases.

#### Breaking Changes

The Argo CD deletes all **in-flight** hooks if you terminate running sync operation. The hook state assessment change implemented in this release the Argo CD enables detection of 
an in-flight state for all Kubernetes resources including `Deployment`, `PVC`, `StatefulSet`, `ReplicaSet` etc. So if you terminate the sync operation that has, for example,
`StatefulSet` hook that is `Progressing` it will be deleted. The long-running jobs are not supposed to be used as a sync hook and you should consider using
[Sync Waves](https://argo-cd.readthedocs.io/en/stable/user-guide/sync-waves/) instead.

#### New Features

##### Helm 1st-Class Support

We know that for many of our users, they want to deploy existing Helm charts using Argo CD. Up until now that has required you to create an Argo CD app in a Git repo that does nothing but point to that chart. Now you can use a Helm chart repository is the same way as a Git repository.

On top of that, we've improved support for Helm apps. The most common types of Helm hooks such as `pre-install` and `post-install` are supported as well as a the delete policy `before-hook-creation` which makes it easier to work with hooks.

##### Orphan Resources

Some users would like to make sure that resources in a namespace are managed only by Argo CD. So we've introduced the concept of an "orphan resource" - any resource that is in namespace associated with an app, but not managed by Argo CD. This is enabled in the project settings. Once enabled, Argo CD will show in the app view any resources in the app's namespace that is not managed by Argo CD. 

https://youtu.be/9ZoTevVQf5I

##### Sync Windows

There may be instances when you want to control the times during which an Argo CD app can sync. Sync Windows now gives you the capability to create windows of time in which apps are either allowed or denied the ability to sync. This can apply to both manual and auto-sync, or just auto-sync. The windows are configured at the project level and assigned to apps using app name, namespace or cluster. Wildcards are supported for all fields.

### New Features

#### Server Certificate And Known Hosts Management

The Server Certificate And Known Hosts Management feature makes it really easy to connect private Git repositories to Argo CD. Now Argo CD provides UI and CLI which
enables managing certificates and known hosts which are used to access Git repositories. It is also possible to configure both hosts and certificates in a declarative manner using
[argocd-ssh-known-hosts-cm](https://github.com/argoproj/argo-cd/blob/master/docs/operator-manual/argocd-ssh-known-hosts-cm.yaml) and 
[argocd-tls-certs-cm.yaml](https://github.com/argoproj/argo-cd/blob/master/docs/operator-manual/argocd-tls-certs-cm.yaml) config maps.

#### Self-Healing

The existing Automatic Sync feature allows to automatically apply any new changes in Git to the target Kubernetes cluster. However, Automatic Sync does not cover the case when the
application is out of sync due to the unexpected change in the target cluster. The Self-Healing feature fills this gap. With Self-Healing enabled Argo CD automatically pushes the desired state from Git into the cluster every time when state deviation is detected.

**Anonymous access** - enable read-only access without authentication to anyone in your organization.

Support for Git LFS enabled repositories - now you can store Helm charts as tar files and enable Git LFS in your repository.

**Compact diff view** - compact diff summary of the whole application in a single view.

**Badge for application status** - add badge with the health and sync status of your application into README.md of your deployment repo.

**Allow configuring google analytics tracking** - use Google Analytics to check how many users are visiting UI or your Argo CD instance.

#### Backward Incompatible Changes
- Kustomize v1 support is removed. All kustomize charts are built using the same Kustomize version
- Kustomize v2.0.3 upgraded to v3.1.0 . We've noticed one backward incompatible change: https://github.com/kubernetes-sigs/kustomize/issues/42 . Starting v2.1.0 namespace prefix feature works with CRD ( which might cause renaming of generated resource definitions)
- Argo CD config maps must be annotated with `app.kubernetes.io/part-of: argocd` label. Make sure to apply updated `install.yaml` manifest in addition to changing image version.

### New Features

#### Sync Waves

Sync waves feature allows executing a sync operation in a number of steps or waves. Within each synchronization phase (pre-sync, sync, post-sync) you can have one or more waves,
than allows you to ensure certain resources are healthy before subsequent resources are synced.

#### Optimized Interaction With Git

Argo CD needs to execute `git fetch` operation to access application manifests and `git ls-remote` to resolve ambiguous git revision. The `git ls-remote` is executed very frequently
and although the operation is very lightweight it adds unnecessary load on Git server and might cause performance issues. In v1.1 release, the application reconciliation process was
optimized which significantly reduced the number of Git requests. With v1.1 release, Argo CD should send 3x ~ 5x fewer Git requests.

#### User Defined Application Metadata

User-defined Application metadata enables the user to define a list of useful URLs for their specific application and expose those links on the UI
(e.g. reference to a CI pipeline or an application-specific management tool). These links should provide helpful shortcuts that make easier to integrate Argo CD into existing
systems by making it easier to find other components inside and outside Argo CD.

### Deprecation Notice

## v1.0.0 (2019-05-16)

### New Features

#### Network View

A new way to visual application resources had been introduced to the Application Details page. The Network View visualizes connections between Ingresses, Services and Pods
based on ingress reference service, service's label selectors and labels. The new view is useful to understand the application traffic flow and troubleshot connectivity issues.

#### Custom Actions

Argo CD introduces Custom Resource Actions to allow users to provide their own Lua scripts to modify existing Kubernetes resources in their applications. These actions are exposed in the UI to allow easy, safe, and reliable changes to their resources.  This functionality can be used to introduce functionality such as suspending and enabling a Kubernetes cronjob, continue a BlueGreen deployment with Argo Rollouts, or scaling a deployment. 

#### UI Enhancements & Usability Enhancements

* New color palette intended to highlight unhealthily and out-of-sync resources more clearly.
* The health of more resources is displayed, so it easier to quickly zoom to unhealthy pods, replica-sets, etc.
* Resources that do not have health no longer appear to be healthy. 
* Support for configuring Git repo credentials at a domain/org level
* Support for configuring requested OIDC provider scopes and enforced RBAC scopes
* Support for configuring monitored resources whitelist in addition to excluded resources

### New Features

#### Improved UI

Many improvements to the UI were made, including:

* Table view when viewing applications
* Filters on applications
* Table view when viewing application resources
* YAML editor in UI
* Switch to text-based diff instead of json diff
* Ability to edit application specs

#### Custom Health Assessments (CRD Health)

Argo CD has long been able to perform health assessments on resources, however this could only
assess the health for a few native kubernetes types (deployments, statefulsets, daemonsets, etc...).
Now, Argo CD can be extended to gain understanding of any CRD health, in the form of Lua scripts.
For example, using this feature, Argo CD now understands the CertManager Certificate CRD and will
report a Degraded status when there are issues with the cert.

#### Configuration Management Plugins

Argo CD introduces Config Management Plugins to support custom configuration management tools other
than the set that Argo CD provides out-of-the-box (Helm, Kustomize, Ksonnet, Jsonnet). Using config
management plugins, Argo CD can be configured to run specified commands to render manifests. This
makes it possible for Argo CD to support other config management tools (kubecfg, kapitan, shell
scripts, etc...).

#### High Availability

Argo CD is now fully HA. A set HA of manifests are provided for users who wish to run Argo CD in
a highly available manner. NOTE: The HA installation will require at least three different nodes due
to pod anti-affinity roles in the specs.

#### Improved Application Source

* Support for Kustomize 2
* YAML/JSON/Jsonnet Directories can now be recursed
* Support for Jsonnet external variables and top-level arguments

#### Additional Prometheus Metrics

Argo CD provides the following additional prometheus metrics:
* Sync counter to track sync activity and results over time
* Application reconciliation (refresh) performance to track Argo CD performance and controller activity
* Argo CD API Server metrics for monitoring HTTP/gRPC requests

#### Fuzzy Diff Logic

Argo CD can now be configured to ignore known differences for resource types by specifying a json
pointer to the field path to ignore. This helps prevent OutOfSync conditions when a user has no
control over the manifests. Ignored differences can be configured either at an application level, 
or a system level, based on a group/kind.

#### Resource Exclusions

Argo CD can now be configured to completely ignore entire classes of resources group/kinds.
Excluding high-volume resources improves performance and memory usage, and reduces load and
bandwidth to the Kubernetes API server. It also allows users to fine-tune the permissions that
Argo CD needs to a cluster by preventing Argo CD from attempting to watch resources of that
group/kind.

#### gRPC-Web Support

The argocd CLI can be now configured to communicate to the Argo CD API server using gRPC-Web
(HTTP1.1) using a new CLI flag `--grpc-web`. This resolves some compatibility issues users were
experiencing with ingresses and gRPC (HTTP2), and should enable argocd CLI to work with virtually
any load balancer, ingress controller, or API gateway.

#### CLI features

Argo CD introduces some additional CLI commands:

* `argocd app edit APPNAME` - to edit an application spec using preferred EDITOR
* `argocd proj edit PROJNAME` - to edit an project spec using preferred EDITOR
* `argocd app patch APPNAME` - to patch an application spec
* `argocd app patch-resource APPNAME` - to patch a specific resource which is part of an application


### Breaking Changes

#### Label selector changes, dex-server rename

The label selectors for deployments were been renamed to use kubernetes common labels
(`app.kubernetes.io/name=NAME` instead of `app=NAME`). Since K8s deployment label selectors are
immutable, during an upgrade from v0.11 to v0.12, the old deployments should be deleted using
`--cascade=false` which allows the new deployments to be created without introducing downtime.
Once the new deployments are ready, the older replicasets can be deleted. Use the following
instructions to upgrade from v0.11 to v0.12 without introducing downtime:

```
# delete the deployments with cascade=false. this orphan the replicasets, but leaves the pods running
kubectl delete deploy --cascade=false argocd-server argocd-repo-server argocd-application-controller

# apply the new manifests and wait for them to finish rolling out
kubectl apply <new install manifests>
kubectl rollout status deploy/argocd-application-controller
kubectl rollout status deploy/argocd-repo-server
kubectl rollout status deploy/argocd-application-controller

# delete old replicasets which are using the legacy label
kubectl delete rs -l app=argocd-server
kubectl delete rs -l app=argocd-repo-server
kubectl delete rs -l app=argocd-application-controller

# delete the legacy dex-server which was renamed
kubectl delete deploy dex-server
```

#### Deprecation of spec.source.componentParameterOverrides

For declarative application specs, the `spec.source.componentParameterOverrides` field is now
deprecated in favor of application source specific config. They are replaced with new fields
specific to their respective config management. For example, a Helm application spec using the
legacy field:

```yaml
spec:
  source:
    componentParameterOverrides:
    - name: image.tag
      value: v1.2
```

should move to:

```yaml
spec:
  source:
    helm:
      parameters:
      - name: image.tag
        value: v1.2
```

Argo CD will automatically duplicate the legacy field values to the new locations (and vice versa)
as part of automatic migration. The legacy `spec.source.componentParameterOverrides` field will be
kept around for the v0.12 release (for migration purposes) and will be removed in the next Argo CD
release.

#### Removal of spec.source.environment and spec.source.valuesFiles

The `spec.source.environment` and `spec.source.valuesFiles` fields, which were deprecated in v0.11,
are now completely removed from the Application spec.


#### API/CLI compatibility

Due to API spec changes related to the deprecation of componentParameterOverrides, Argo CD v0.12
has a minimum client version of v0.12.0. Older CLI clients will be rejected.

## v0.11.0 (2019-01-10)
This is Argo CD's biggest release ever and introduces a completely redesigned controller architecture.

### New Features

#### Performance & Scalability
The application controller has a completely redesigned architecture which improved performance and
scalability during application reconciliation.

This was achieved by introducing an in-memory, live state cache of lightweight Kubernetes object 
metadata. During reconciliation, the controller no longer performs expensive, in-line queries of app
related resources in K8s API server, instead relying on the metadata available in the live state 
cache. This dramatically improves performance and responsiveness, and is less burdensome to the K8s
API server.

#### Object relationship visualization for CRDs
With the new controller design, Argo CD is now able to understand ownership relationship between
*all* Kubernetes objects, not just the built-in types. This enables Argo CD to visualize
parent/child relationships between all kubernetes objects, including CRDs.

#### Multi-namespaced applications
During sync, Argo CD will now honor any explicitly set namespace in a manifest. Manifests without a
namespace will continue deploy to the "preferred" namespace, as specified in app's
`spec.destination.namespace`. This enables support for a class of applications which install to
multiple namespaces. For example, Argo CD can now install the
[prometheus-operator](https://github.com/helm/charts/tree/master/stable/prometheus-operator)
helm chart, which deploys some resources into `kube-system`, and others into the
`prometheus-operator` namespace.

#### Large application support
Full resource objects are no longer stored in the Application CRD object status. Instead, only
lightweight metadata is stored in the status, such as a resource's sync and health status.
This change enabled Argo CD to support applications with a very large number of resources 
(e.g. istio), and reduces the bandwidth requirements when listing applications in the UI.

#### Resource lifecycle hook improvements
Resource lifecycle hooks (e.g. PreSync, PostSync) are now visible/manageable from the UI.
Additionally, bare Pods with a restart policy of Never can now be used as a resource hook, as an
alternative to Jobs, Workflows.

#### K8s recommended application labels
The tracking label for resources has been changed to use `app.kubernetes.io/instance`, as
recommended in [Kubernetes recommended labels](https://kubernetes.io/docs/concepts/overview/working-with-objects/common-labels/),
(changed from `applications.argoproj.io/app-name`). This will enable applications managed by Argo CD
to interoperate with other tooling which are also converging on this labeling, such as the
Kubernetes dashboard. Additionally, Argo CD no longer injects any tracking labels at the
`spec.template.metadata` level.

#### External OIDC provider support
Argo CD now supports auth delegation to an existing, external OIDC providers without the need for
running Dex (e.g. Okta, OneLogin, Auth0, Microsoft, etc...)

The optional, [Dex IDP OIDC provider](https://github.com/dexidp/dex) is still bundled as part of the
default installation, in order to provide a seamless out-of-box experience, enabling Argo CD to
integrate with non-OIDC providers, and to benefit from Dex's full range of
[connectors](https://dexidp.io/docs/connectors/).

#### OIDC group bindings to Project Roles
OIDC group claims from an OAuth2 provider can now be bound to a Argo CD project roles. Previously,
group claims could only be managed in the centralized ConfigMap, `argocd-rbac-cm`. They can now be
managed at a project level. This enables project admins to self service access to applications
within a project.

#### Declarative Argo CD configuration
Argo CD settings can be now be configured either declaratively, or imperatively. The `argocd-cm`
ConfigMap now has a `repositories` field, which can reference credentials in a normal Kubernetes
secret which you can create declaratively, outside of Argo CD.

#### Helm repository support
Helm repositories can be configured at the system level, enabling the deployment of helm charts
which have a dependency to external helm repositories.

### Breaking changes:

* Argo CD's resource names were renamed for consistency. For example, the application-controller
  deployment was renamed to argocd-application-controller. When upgrading from v0.10 to v0.11,
  the older resources should be pruned to avoid inconsistent state and controller in-fighting.

* As a consequence to moving to recommended kubernetes labels, when upgrading from v0.10 to v0.11,
  all applications will immediately be OutOfSync due to the change in tracking labels. This will
  correct itself with another sync of the application. However, since Pods will be recreated, please
  take this into consideration, especially if your applications are configured with auto-sync.

* There was significant reworking of the `app.status` fields to reduce the payload size, simplify
  the datastructure and remove fields which were no longer used by the controller. No breaking
  changes were made in `app.spec`.

* An older Argo CD CLI (v0.10 and below) will not be compatible with Argo CD v0.11. To keep
  CI pipelines in sync with the API server, it is recommended to have pipelines download the CLI
  directly from the API server https://${ARGOCD_SERVER}/download/argocd-linux-amd64 during the CI
  pipeline.

### Notes about upgrading from v0.8
* Cluster wide resources should be allowed in default project (due to issue #330):

```
argocd project allow-cluster-resource default '*' '*'
```

* Projects now provide the ability to allow or deny deployments of cluster-scoped resources
(e.g. Namespaces, ClusterRoles, CustomResourceDefinitions). When upgrading from v0.8 to v0.9, to
match the behavior of v0.8 (which did not have restrictions on deploying resources) and continue to
allow deployment of cluster-scoped resources, an additional command should be run:

```bash
argocd proj allow-cluster-resource default '*' '*'
```

The above command allows the `default` project to deploy any cluster-scoped resources which matches
the behavior of v0.8.

* The secret keys in the argocd-secret containing the TLS certificate and key, has been renamed from
  `server.crt` and `server.key` to the standard `tls.crt` and `tls.key` keys. This enables Argo CD
  to integrate better with Ingress and cert-manager. When upgrading to v0.9, the `server.crt` and
  `server.key` keys in argocd-secret should be renamed to the new keys.

## v0.8.0 (2018-09-04)

### Notes about upgrading from v0.7
* The RBAC model has been improved to support explicit denies. What this means is that any previous
RBAC policy rules, need to be rewritten to include one extra column with the effect:
`allow` or `deny`. For example, if a rule was written like this:
    ```
    p, my-org:my-team, applications, get, */*
    ```
    It should be rewritten to look like this:
    ```
    p, my-org:my-team, applications, get, */*, allow
    ```

### Changes since v0.7:
+ Support kustomize as an application source (issue #510)
+ Introduce project tokens for automation access (issue #498)
+ Add ability to delete a single application resource to support immutable updates (issue #262)
+ Update RBAC model to support explicit denies (issue #497)
