June 2026

Version	Compatibility with Kubernetes version	Version status	Description	Impact
v0.4.6-vke.1	v1.26 ≤ Cluster version	Maintained	Community feature alignment The prewarming pool's object model has evolved from ‌direct Pod binding‌ to ‌Sandbox binding‌. Sandbox Service creation is now optional‌. VCI enhancements In-place updates‌ of Sandbox container images are supported, eliminating the need for Pod recreation. Snapshot creation upon Sandbox suspension is now ‌optional‌ (previously default). Helm Chart template optimizations The workload type of agent-sandbox-controller changed from StatefulSet to Deployment. Helm values ‌are aligned with community standards‌. Bug fixes Fixed an issue where the E2B List API did not support pagination.	Due to the workload type change from ‌StatefulSet‌ to ‌Deployment‌, ‌existing Sandboxes cannot be created, deleted, or modified during add-on upgrades‌. In the old version, a Service is automatically created for each Pod, and this behavior cannot be disabled. In the new version, Service creation is optional. The Helm Chart's defaultSandboxService parameter defaults to true (creating Pod Services) to ensure upgrade compatibility. Helm Chart template parameters have changed. After selecting this version, you need to configure the relevant parameters. For details, please see the installation guide.
