Changelog since v1.26.0

Changes by Kind

API Change

The list-type of the alpha resourceClaims field introduced to Pods in 1.26.0 was modified from "set" to "map", resolving an incompatibility with use of this schema in CustomResourceDefinitions and with server-side apply. (#114617, @JoelSpeed) [SIG API Machinery]

Feature

Kubernetes is now built with Go 1.19.5 (#115014, @cpanato) [SIG Release and Testing]

Failing Test

Deflake a preemption test that may patch Nodes incorrectly. (#114350, @Huang-Wei) [SIG Scheduling and Testing]

Bug or Regression

Client-go: fixes potential data races retrying requests using a custom io.Reader body; with this fix, only requests with no body or with string / []byte / runtime.Object bodies can be retried (#113933, @liggitt) [SIG API Machinery]
Do not include preemptor pod metadata in the event message (#114946, @mimowo) [SIG Scheduling]
Do not include preemptor pod metadata in the message of DisruptionTarget condition (#114945, @mimowo) [SIG Scheduling]
Failed pods associated with a job with parallelism = 1 are recreated by the job controller honoring exponential backoff delay again. However, for jobs with parallelism > 1, pods might be created without exponential backoff delay. (#115027, @nikhita) [SIG Apps]
Fix a regression that the scheduler always goes through all Filter plugins. (#114524, @Huang-Wei) [SIG Scheduling]
Fix bug in CRD Validation Rules (beta) and ValidatingAdmissionPolicy (alpha) where all admission requests could result in internal error: runtime error: index out of range [3] with length 3 evaluating rule: <rule name> under certain circumstances. (#114861, @jpbetz) [SIG API Machinery, Auth and Cloud Provider]
Fix clearing of rate-limiter for the queue of checks for cleaning stale pod disruption conditions. The bug could result in the PDB synchronization updates firing too often or the pod disruption cleanups taking too long to happen. (#114780, @mimowo) [SIG Apps]
Fixed DaemonSet to update the status even if it fails to create a pod. (#114819, @gjkim42) [SIG Apps and Testing]
Fixes stuck apiserver if an aggregated apiservice returned 304 Not Modified for aggregated discovery information (#114459, @alexzielenski) [SIG API Machinery]
Fixing issue in Winkernel Proxier - Unexpected active TCP connection drops while horizontally scaling the endpoints for a LoadBalancer Service with External Traffic Policy: Local (#114038, @princepereira) [SIG Network]
Fixing issue with Winkernel Proxier - No ingress load balancer rules with endpoints to support load balancing when all the endpoints are terminating. (#114453, @princepereira) [SIG Network and Windows]
Optimizing loadbalancer creation with the help of attribute Internal Traffic Policy: Local (#114468, @princepereira) [SIG Network]
