Changelog since v1.33.0-alpha.3

Changes by Kind

API Change

  • DRA support for a "one-of" prioritized list of selection criteria to satisfy a device request in a resource claim. (#128586, @mortent) [SIG API Machinery, Apps, Etcd, Node, Scheduling and Testing]
  • For the InPlacePodVerticalScaling feature, the API server will no longer set the resize status to Proposed upon receiving a resize request. (#130574, @natasha41575) [SIG Apps, Node and Testing]
  • The apiserver will now return warnings if you create objects with "invalid" IP or CIDR values (like "192.168.000.005", which should not have the extra zeros). Values with non-standard formats can introduce security problems, and will likely be forbidden in a future Kubernetes release. (#128786, @danwinship) [SIG Apps, Network and Node]
  • When the PodObservedGenerationTracking feature gate is set, the kubelet will populate status.observedGeneration to reflect the pod's latest metadata.generation that it has observed. (#130352, @natasha41575) [SIG API Machinery, Apps, CLI, Node, Release, Scheduling, Storage, Testing and Windows]

Feature

  • Add mechanism that every 5 minutes calculates a digest of etcd and watch cache and exposes it as apiserver_storage_digest metric (#130475, @serathius) [SIG API Machinery, Instrumentation and Testing]
  • Adds apiserver.latency.k8s.io/authentication annotation to the audit log to record the time spent authenticating slow requests.
  • Allow for dynamic configuration of service account name and audience kubelet can request a token for as part of the node audience restriction feature. (#130485, @aramase) [SIG Auth and Testing]
  • Endpoints resources created by the Endpoints controller now have a label indicating this. (Users creating Endpoints by hand can also add this label themselves, but they ought to switch to creating EndpointSlices rather than Endpoints anyway.) (#130564, @danwinship) [SIG Apps and Network]
  • Pod resource checkpointing is now tracked by the allocated_pods_state and actuated_pods_state files, and pod_status_manager_state is no longer used. (#130599, @tallclair) [SIG Node]
  • Scheduling Framework exposes NodeInfo to the ScorePlugin. (#130537, @saintube) [SIG Scheduling, Storage and Testing]
  • Set feature gate OrderedNamespaceDeletion on by default. (#130507, @cici37) [SIG API Machinery and Apps]

Bug or Regression

  • Fix a bug on InPlacePodVerticalScalingExclusiveCPUs feature gate exclusive assignment availability check. (#130559, @esotsal) [SIG Node]
  • Fix kubelet restart unmounts volumes of running pods if the referenced PVC is being deleted by the user (#130335, @carlory) [SIG Node, Storage and Testing]
  • Removed a warning around Linux user namespaces and kernel version. If the feature gate UserNamespacesSupport was enabled, the kubelet previously warned when detecting a Linux kernel version earlier than 6.3.0. User namespace support on Linux typically does still need kernel 6.3 or newer, but it can work in older kernels too. (#130243, @rata) [SIG Node]
  • The BalancedAllocation plugin will skip all best-effort (zero-requested) pod. (#130260, @Bowser1704) [SIG Scheduling]
  • YAML input which might previously have been confused for JSON is now accepted. (#130666, @thockin) [SIG API Machinery]

Other (Cleanup or Flake)

  • Changed the error message displayed when a pod is trying to attach a volume that does not match the label/selector from "x node(s) had volume node affinity conflict" to "x node(s) didn't match PersistentVolume's node affinity". (#129887, @rhrmo) [SIG Scheduling and Storage]
  • Client-gen now sorts input group/versions to ensure stable output generation even with unsorted inputs (#130626, @BenTheElder) [SIG API Machinery]
  • E2e.test: [Feature:OffByDefault] is added to test names when specifying a featuregate which is not on by default (#130655, @BenTheElder) [SIG Auth and Testing]
  • Kubelet no longer logs multiple errors when running on a system with no iptables binaries installed. (#129826, @danwinship) [SIG Network and Node]
