# CRI-O v1.35.9

> Kubernetes Core · 2026-09-21

A narrowly scoped feature release adds checkpoint-restore configuration and changes the default checkpoint behavior. The new default is the main operator-facing concern.

## Action needed
- **[breaking]** Checkpoint-restore configuration and `checkpoint_only` default
  - Checkpoint-restore configuration adds `checkpoint_restore.container_level_enabled` and sets `checkpoint_only` as the default. This change ships in cri-o v1.35.9.
