The katalyst add-on provides fine-grained resource management capabilities, such as topology reporting in Remote Direct Memory Access (RDMA) scenarios and core binding in Non-Uniform Memory Access (NUMA)-aware scheduling. This topic describes the change history of the katalyst add-on.

For more information about add-ons and how to use them, see Add-on management.

v0.5.13-vke.14	v1.24.15-vke.13 ≤ Cluster version < v1.26 v1.26.10-vke.13 ≤ Cluster version < v1.36	Maintained	Supports automatic detection of Cgroup v1 and Cgroup v2 nodes. Fixes an issue where some versions lacked a closed‑interval configuration for Kubernetes version compatibility.	None

July 2025

Version	Compatibility with Kubernetes version	Version status	Description	Impact
v0.5.13-vke.10	v1.24.15-vke.13 ≤ Cluster version < v1.26 Cluster version ≥ v1.26.10-vke.13	Maintained	The Identity and Access Management (IAM) authentication method of the add-on is optimized.	None

April 2025

Version	Compatibility with Kubernetes version	Version status	Description	Impact
v0.5.13-vke.9	v1.24.15-vke.13 ≤ Cluster version < v1.26 Cluster version ≥ v1.26.10-vke.13	Maintained	The issue where the add-on fails to start after being upgraded from an earlier version is fixed. Fixed the issue where the number of data points queried from Volcengine Managed Service for Prometheus (VMP) by the intelligent Horizontal Pod Autoscaler (HPA) exceeded VMP's query limit.	After you upgrade the version from v0.3.5-vke.5 to v0.5.x or later, you need to change the topology-manager-policy field of the kubelet parameter for the node pool associated with the add-on to none, and synchronize the update to existing nodes. For detailed operations, refer to FAQ.
