Release Schedule
Next Deadline: Feature Blog Freeze, October 30
We are in the countdown to Code Freeze and this week is full of deadlines. Finish your feature blog entries by October 30, followed by any major deprecations/removals by November 4, with Code and Test Freeze on November 8th.
Featured PRs
125258 Etcd Kubernetes interface
Introduces the alpha version of a defined interface for Kubernetes-etcd communications. The interface will improve tests and reliability as well as permitting (but not implementing) alternate backends. It covers data storage and leases.
KEP of the Week
KEP-1847: Auto delete PVCs created by StatefulSet
The KEP implements automatic deletion of “Persistent Volume Claims (PVCs)” associated with StatefulSets upon their deletion or scale-down. It introduced a PersistentVolumeClaimRetentionPolicy field, allowing users to opt-in for PVC deletion. This enhancement simplifies resource management, while preserving application state during regular operations.
This KEP is tracked for stable release in the ongoing v1.32 cycle, but is considered “at risk” because it is missing requirements for Code Freeze.
