| Version | Kublr Agent | Notes |
|---|---|---|
| 1.28 | 1.28.8-1 | Default version: v1.28.8 |
| 1.27 | 1.27.12-1 | |
| 1.26 | 1.26.15-1 | |
| 1.25 | 1.25.16-1 | Deprecated in 1.29.0 |

Kublr 1.28 CNCF Kubernetes conformance
Before upgrading your managed cluster, make sure to upgrade all Kublr components to v1.28.0 or above. Note that if you use Pod Security Policies (PSP) in your application deployments, be aware of the PSP end of support in Kubernetes v1.25.0.
Deprecations:
Kublr now supports cluster specification templating. You can utilize Go template functionality in the cluster specification.
The Kublr Helm Manager enables helm package installation on the infrastructure layer before Kubernetes nodes reach the Ready state. The Manager utilizes Kubernetes secrets as CR definitions and operates as a Kubernetes operator, functioning similarly to the native Kubernetes Addon Manager.
Kublr Operator contains values.yaml templating logic in the helm packages. You can specify templates/kublr/values-template.yaml file in the helm chart for values.yaml calculating before install/upgrade begins
The Kublr Operator incorporates values.yaml templating logic in the helm packages. You can specify the templates/kublr/values-template.yaml file in the helm chart to calculate values.yaml before the install/upgrade process begins.
Kublr Helm packages now utilize the Kublr Common package. Helm development standards have been implemented.
The Cluster Controller has undergone a complete refactor of its node update/reconcile logic. As a result, you now have access to comprehensive node status information on the UI.
A Velero-based BackUp controller has been implemented for AWS (technical preview). Please refer to our support portal for usage examples.
