Patch-Release on CuraDevOps

containerd 2.3.4 released with breaking checkpoint-restore change

Mon, 17 Aug 2026 12:38:40 +0000

Platform/SRE — Plan: Despite being a patch release, 2.3.4 ships a breaking change: checkpoint restore in CreateContainer is now disabled by default, requiring an explicit config opt-in. Also fixes a memory leak in the OOM watcher and binary protobuf shim corruption. Review workloads using CRIU/checkpoint restore before upgrading; schedule the upgrade this quarter.

Platform/SRE — Plan: Two regressions introduced in 29.7.0 — image pulls rejecting hardlink targets and file-permission failures on older kernels — are fixed in 29.7.2; if you upgraded to 29.7.x recently, schedule a patch to 29.7.2 to restore stable image pull behavior.

Platform/SRE — Plan: etcd backs every Kubernetes control plane, and a breaking-change flag on a patch release is unusual — review the CHANGELOG and upgrade guide before rolling this out to clusters; no hard deadline, but unreviewed breaking changes in a core datastore warrant a planned change window rather than routine rollout.
