Argo CD v1.6.0 — Release Notes & Engineering Impact

## Quick Start ### Non-HA: ``` kubectl create namespace argocd kubectl apply -n argocd -f https://raw.githubusercontent.com/argoproj/argo-cd/v1.6.0/manifests/install.yaml ``` ### HA: ``` kubectl create namespace argocd kubectl apply -n argocd -f https://raw.githubusercontent.com/argoproj/argo-cd/v1.6.0/manifests/ha/install.yaml ``` [1.6 Release blog post](https://blog.argoproj.io/argo-cd-v1-6-democratizing-gitops-with-gitops-engine-5a17cfc87d62) ### 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. #### Enhancements - feat: upgrade kustomize to v3.6.1 version (#3696) - feat: Add build support for ARM images (#3554) - feat: CLI: Allow setting Helm values literal (#3601) (#3646) - feat: argocd-util settings resource-overrides list-actions (#3616) - feat: adding failure retry (#3548) - feat: Implement GKE ManagedCertificate CRD health checks (#3600) - feat: Introduce diff normalizer knobs and allow for ignoring aggregated cluster roles (#2382) (#3076) - feat: Implement Crossplane CRD health checks (#3581) - feat: Adding deploy time and duration label (#3563) - feat: support delete cluster from UI (#3555) - feat: add button loading status for time-consuming operations (#3559) - feat: Add --logformat switch to API server, repository server and controller (#3408) - feat: Add a Get Repo command to see if Argo CD has a repo (#3523) - feat: Allow selecting TLS ciphers on server (#3524) - feat: Support additional metadata in Application sync operation (#3747) - feat: upgrade redis to 5.0.8-alpine (#3783) #### Bug Fixes - fix: settings manager should invalidate cache after updating repositories/repository credentials (#3672) - fix: Allow unsetting the last remaining values file (#3644) (#3645) - fix: Read cert data from kubeconfig during cluster addition and use if present (#3655) (#3667) - fix: oidc should set samesite cookie (#3632) - fix: Allow underscores in hostnames in certificate module (#3596) - fix: apply scopes from argocd-rbac-cm to project jwt group searches (#3508) - fix: fix nil pointer dereference error after cluster deletion (#3634) - fix: Prevent possible nil pointer dereference when getting Helm client (#3613) - fix: Allow CLI version command to succeed without server connection (#3049) (#3550) - fix: Fix login with port forwarding (#3574) - fix: use 'git show-ref' to both retrieve and store generated manifests (#3578) - fix: enable redis retries; add redis request duration metric (#3575) - fix: Disable keep-alive for HTTPS connection to Git (#3531) - fix: use uid instead of named user in Dockerfile (#3108) #### Other - refactoring: Gitops engine (#3066)
