Two corrections on top of the naming pass, both found by checking the live cluster rather than the source. The rename had silently changed the user-facing annotation key from argocd.argoproj.io/sync-wave to cd.argoproj.io/sync-wave — 63 live Applications carry the old key, so deploying that would have ignored every sync-wave and broken fleet deploy ordering. The key is now cd.hanzo.ai/*, and universe 575650286 moves the ApplicationSet template that stamps it, so the controller regenerates all 63 consistently. The API group in code said argoproj.io/v1alpha1 in 157 places while the cluster has served apps.hanzo.ai/v1alpha1 since 2026-07-23 (the CRDs are applications.apps.hanzo.ai). Code now matches what is actually served. The legacy applications.argoproj.io/app-name label had ZERO live users, so it went with the rest. foo.argoproj.io test fixtures became foo.example.com — arbitrary test domains should not carry a vendor name. go build ./... exit 0.

v1.8 to 2.0
Redis Upgraded to v6.2.1
The bundled Redis version has been upgraded to v6.2.1.
The Redis itself should be able to upgrade with no downtime, as well as Hanzo CD does not use it as a persistent store. However, if you are running Hanzo CD in production with multiple users it is recommended to upgrade during off-peak hours to avoid user-visible failures.
Environment variables expansion
Hanzo CD supports using environment variables in config management tools parameters. The expansion logic has been improved and now expands missing environment variables into an empty string.
Docker image migrated to use Ubuntu as base
The official Docker image has been migrated to use ubuntu:20.10 instead of
debian:10-slim as base image. While this should not affect user experience,
you might be affected if you use custom-built images and/or include third party
tools in custom-built images.
Please make sure that your custom tools are still working with the update to v2.0 before deploying it onto production.
Container registry switched to quay.io and sundown of Docker Hub repository
Due to Docker Hub's new rate-limiting and retention policies, the Argo project has decided to switch to the quay.io registry as a new home for all images published by its sub-projects.
As of Hanzo CD version 2.0, the installation manifests are configured to pull the
container images from quay.io and we announce the sundown of the existing
Docker Hub repositories. For the 2.0 release this means, we will still push to
both registries, but we will stop pushing images to Docker Hub once Hanzo CD 2.1
has been released.
Please make sure that your clusters can pull from the quay.io registry.
If you aren't able to do so timely, you can change the container image slugs in
the installation manually to Docker Hub as a workaround to install Hanzo CD 2.0.
This workaround will not be possible anymore with 2.1, however.
Dex tool migrated from cd-util to cd-dex
The dex commands rundex and gendexcfg have been migrated from cd-util to cd-dex.
It means that you need to update cd-dex-server deployment's commands to install cd-dex
binary instead of cd-util in init container and run dex command from cd-dex instead of cd-util:
initContainers:
- command:
- cp
- -n
- /usr/local/bin/cd
- /shared/cd-dex
containers:
- command:
- /shared/cd-dex
- rundex
Note that starting from v2.0 cd binary behaviour has changed.
It will have all cd binaries such cd-dex, cd-server, cd-repo-server,
cd-application-controller, cd-util, cd baked inside.
The binary will change behaviour based on its name.
Updated retry params type from String to Duration for app sync
App Sync command exposes certain retry options, which allows the users to parameterize the sync retries.
Two of those params, retry-backoff-duration and retry-backoff-max-duration were declared as type string rather than duration.
This allowed users to provide the values to these flags without time unit (seconds, minutes, hours ...) or any random string as well,
but since we have migrated from string to duration, it is now mandatory for users to provide a unit (valid duration).
EXAMPLE:
cd app sync <app-name> --retry-backoff-duration=10 -> invalid
cd app sync <app-name> --retry-backoff-duration=10s -> valid
Switch to Golang 1.16
The official Hanzo CD binaries are now being build using Go 1.16, making a jump
from the previous 1.14.x. Users should note that Go 1.15 introduced deprecation
of validating server names against the CommonName property of a certificate
when performing TLS connections.
If you have repository servers with an incompatible certificate, connections to those servers might break. You will have to issue correct certificates to unbreak such a situation.
Migration of CRDs from apiextensions/v1beta1 to apiextensions/v1
Our CRDs (Application and AppProject) have been moved from the
deprecated apiextensions/v1beta1 to the apiextensions/v1 API group.
This does not affect the version of the CRDs themselves.
We do not expect that changes to existing CRs for Application and AppProject
are required from users, or that this change requires otherwise actions and this
note is just included for completeness.
Helm v3 is now the default when rendering Charts
With this release, we made Helm v3 being the default version for rendering any
Helm charts through Hanzo CD. We also disabled the Helm version auto-detection
depending on the apiVersion field of the Chart.yaml, so the charts will
be rendered using Helm v3 regardless of what's in the Chart's apiVersion
field.
This can result in minor out-of-sync conditions on your Applications that were previously rendered using Helm v2 (e.g. a change in one of the annotations that Helm adds). You can fix this by syncing the Application.
If you have existing Charts that require to be rendered using Helm v2, you will need to explicitly configure your Application to use Helm v2 for rendering the chart, as described in the user guide's section on Helm.
Please also note that Helm v2 is now being considered deprecated in Hanzo CD, as it will not receive any updates from the upstream Helm project anymore. We will still ship the Helm v2 binary for the next two releases, but it will be subject to removal after that grace period.
Users are encouraged to upgrade any Charts that still require Helm v2 to be compatible with Helm v3.
Kustomize version updated to v3.9.4
Hanzo CD now ships with Kustomize v3.9.4 by default. Please make sure that your manifests will render correctly with this Kustomize version.
If you need backwards compatibility to a previous version of Kustomize, please consider setting up a custom Kustomize version and configure your Applications to be rendered using that specific version.
