- New whole-object local cache: immutable data objects on S3 are kept on the local node, so repeated reads after a restore — and re-importing the same snapshot — hit the local cache instead of going…
- Reduced read amplification during restore: scattered small reads are coalesced into whole-object GETs, and the concurrent fetch budget is capped.
- With the default MinIO setup, cross-node restore / create-from-snapshot reaches running in under 1 second.
- S3lvol hot upgrade: fixes the EIO errors seen inside sandboxes when upgrading the CubeS3lvol storage component.
- Local-filesystem storage for component repositories and template artifacts (#1749): component repositories and template artifacts can be stored on S3 / local disk / PVC / NFS.
- Incremental snapshot fix (#1343): fixed data loss in incremental snapshots.

What changed: recent CubeSandbox releases
7 stable releases in the last 90 days · Full changelog
- Dedicated kernel assets release (BM + PVM guest + PVM host).
- A standalone template-center service enables multi-replica CubeMaster deployment.
- The lifecycle management service now supports active/standby deployment.
- Snapshot support for Host Mount and Volume Plugin: snapshot, restore, rollback, and clone now work for sandboxes with external mounts (#1654, #1656).
- Standalone CubeTemplateCenter: template build / delete / reclaim is split out of CubeMaster into an independently scalable multi-replica service. Build artifacts are persisted to S3/MinIO (AWS S3…
- Faster same-bucket cross-node snapshot restore (#1663): restoring a snapshot from the same bucket now uses object-storage server-side copy, which is significantly faster. Also improves…
- CLM now supports active/standby disaster recovery.
- Newly created templates and snapshots now record the versions of the components they depend on. After components on compute nodes are upgraded, historical templates and snapshots remain usable,…
- Architecture: fewer components to deploy — the network-agent component is merged into Cubelet, reducing inter-process RPC calls during sandbox creation; TAP device lifecycle management is…
- Performance: optimized the eBPF network policy provisioning path, significantly reducing sandbox creation latency for sandboxes with network rules; removed unnecessary netlink dump operations so…
- CubeS3lvol COW (#1490): besides the local XFS COW engine, cubecow now supports remote snapshot storage on S3 object storage, enabling cross-node pause/resume and snapshot cloning.
- Private HTTP image registry support (#1369): pull images from HTTP image registries to build templates.
- Built-in MinIO as the default S3 volume backend (#1408): MinIO is deployed by default as the S3 backend for the volume feature and cross-node pause/resume. Users can also specify their own S3 backend.
