Changelog since v1.21.10

Changes by Kind

API Change

Fixes a regression in v1beta1 PodDisruptionBudget handling of "strategic merge patch"-type API requests for the selector field. Prior to 1.21, these requests would merge matchLabels content and replace matchExpressions content. In 1.21, patch requests touching the selector field started replacing the entire selector. This is consistent with server-side apply and the v1 PodDisruptionBudget behavior, but should not have been changed for v1beta1. (#108142, @liggitt) [SIG Auth and Testing]

Feature

Kubernetes is now built with Golang 1.16.15 (#108565, @cpanato) [SIG Cloud Provider, Instrumentation, Release and Testing]

Bug or Regression

Bump sigs.k8s.io/apiserver-network-proxy/konnectivity-client to v0.0.30, fixing goroutine leaks in kube-apiserver. (#108440, @andrewsykim) [SIG API Machinery and Cloud Provider]
Fixes a bug where a partial EndpointSlice update could cause node name information to be dropped from endpoints that were not updated. (#108203, @robscott) [SIG Network]
Kubelet: Fixes memory usage within the kubelet's inotify subsystem. (#108335, @rphillips) [SIG API Machinery, CLI, Cloud Provider, Cluster Lifecycle, Instrumentation, Node and Storage]
