#Release Notes

#4.3.0

#Features and Enhancements

#Support for Kubernetes 1.34

ACP 4.3 adds support for Kubernetes 1.34 for platform-managed cluster scenarios.

For upgrades to ACP 4.3, the workload-cluster compatible versions are 1.34, 1.33, 1.32, and 1.31. This compatible-version requirement determines whether the global cluster can be upgraded and is separate from the third-party cluster management range.

For more information, see Kubernetes Support Matrix.

#CVO-Based Cluster Upgrade Workflow

ACP 4.3 introduces a Cluster Version Operator (CVO)-based upgrade workflow for both global and workload clusters.

Key capabilities include:

• Preparing upgrade artifacts and the upgrade controller with bash upgrade.sh
• Running preflight checks before execution
• Requesting upgrades from the Web Console or by updating ClusterVersionShadow.spec.desiredUpdate
• Inspecting conditions, preflight results, stages, and history from cvsh.status

ACP CLI also introduces upgrade-oriented administrator commands such as ac adm upgrade, ac adm upgrade status, --to-latest, --to, and --allow-explicit-upgrade for requesting and troubleshooting workload cluster upgrades from the current context.

For operational guidance, see Upgrade.

#Standalone Cluster Plugin Upgrade

ACP 4.3 adds standalone upgrade support for cluster plugins that use the Aligned or Agnostic life cycle.

The Cluster Plugins page now shows the plugin life cycle, and eligible plugins can be upgraded independently from the list page or details page. Core plugins continue to follow cluster upgrades.

#MicroOS-Based Global Clusters on Huawei DCS

ACP 4.3 allows administrators to create the global cluster on Huawei DCS with MicroOS-based immutable infrastructure. This extends the immutable operating model from workload clusters to platform installation scenarios on DCS.

For more information, see About Immutable Infrastructure.

#Huawei Cloud Stack Support in Immutable Infrastructure

ACP 4.3 adds Immutable Infrastructure support for Huawei Cloud Stack (HCS). The HCS provider documentation now covers provider overview, installation, cluster creation, node management, cluster upgrades, and provider APIs in the Immutable Infrastructure documentation set.

For more information, see About Immutable Infrastructure.

#VMware vSphere Support in the 4.3 Cycle

ACP 4.3 begins introducing Immutable Infrastructure support for VMware vSphere. The provider work is now tracked in the Immutable Infrastructure documentation set, while the public installation details and finalized plugin naming are still being published.

For more information, see About Immutable Infrastructure.

#New Web Console Preview Entry

ACP Core now provides the top-navigation anchor required by the next-generation Web Console experience. When Alauda Container Platform Web Console Base is installed on the global cluster, users in the Container Platform and Administrator views can open the new console through a Preview Next-Gen Console entry in a separate browser tab.

The experience is designed for gradual migration and works with the Web Console Base plugin on the global cluster and the Web Console Collector plugin on workload clusters.

#Containerd 2.0 Baseline

ACP 4.3 upgrades the platform runtime baseline to containerd 2.0. Review runtime-dependent operational procedures before upgrading environments that rely on customized containerd configuration.

#Expanded Third-Party Cluster Management Range

For third-party clusters, ACP 4.3 now accepts Kubernetes versions in the range >=1.19.0 <1.35.0.

This management range is separate from the compatible Kubernetes versions used to determine whether the global cluster can be upgraded.

Product documentation continues to publish only the Kubernetes versions that have passed product validation for third-party cluster support and the default Extend baseline.

Product validation for the Extend baseline covers the following capability areas:

• Installing and using Operators
• Installing and using Cluster Plugins
• ClickHouse-based logging
• VictoriaMetrics-based monitoring

This does not mean that all specific Operators or Cluster Plugins are covered by product validation.

For specific Operators or Cluster Plugins outside this baseline, refer to the relevant product documentation or contact technical support.
