Container Images

All container images are available as manifest lists and support the described architectures. It is also possible to pull a specific architecture directly by adding the "-$ARCH" suffix to the container image name.

Changelog since v1.27.0-beta.0

Changes by Kind

API Change

Added a new alpha API: ClusterTrustBundle (certificates.k8s.io/v1alpha1). A ClusterTrustBundle may be used to distribute X.509 trust anchors to workloads within the cluster. (#113218, @ahmedtd) [SIG API Machinery, Auth and Testing]
Remove kubernetes.io/grpc standard appProtocol (#116866, @LiorLieberman) [SIG API Machinery and Apps]

Feature

Give terminal phase correctly to all pods that will not be restarted.
In particular, assign Failed phase to pods which are deleted while pending. Also, assign a terminal phase (Succeeded or Failed, depending on the exit statuses of the pod containers) to pods which are deleted while running.
This fixes the issue for jobs using pod failure policy (with JobPodFailurePolicy and PodDisruptionConditions feature gates enabled) that their pods could get stuck in the pending phase when deleted. (#115331, @mimowo) [SIG Cloud Provider, Node and Testing]

Bug or Regression

Fixed two regressions introduced by the PodDisruptionConditions feature (on by default in 1.26):
- pod eviction API calls returned spurious precondition errors and required a second evict API call to succeed
- dry-run eviction API calls persisted a DisruptionTarget condition into the pod being evicted (#116554, @atiratree) [SIG API Machinery and Testing]
Fixes a regression in the pod binding subresource to honor the metadata.uid precondition. This allows kube-scheduler to ensure it is assigns node names to the same instances of pods it made scheduling decisions for. (#116550, @alculquicondor) [SIG API Machinery and Testing]
Fixes bug in beta aggregated discovery endpoint which caused CRD discovery information to be temporarily missing when an Aggregated APIService with the same GroupVersion is deleted (and vice versa). (#116770, @alexzielenski) [SIG API Machinery and Testing]
