Changelog since v1.20.7

Changes by Kind

Feature

• Kubernetes is now built using Go 1.15.13 (#102786, @thejoycekung) [SIG Cloud Provider, Instrumentation, Release and Testing]

Failing Test

• Fixes the should receive events on concurrent watches in same order conformance test to work properly on clusters that auto-create additional configmaps in namespaces (#101950, @liggitt) [SIG API Machinery and Testing]

Bug or Regression

• Added jitter factor to lease controller that better smears load on kube-apiserver over time. (#101652, @marseel) [SIG API Machinery and Scalability]
• Avoid caching the Azure VMSS instances whose network profile is nil (#100948, @feiskyer) [SIG Cloud Provider]
• Azure: avoid setting cached Sku when updating VMSS and VMSS instances (#102005, @feiskyer) [SIG Cloud Provider]
• Fix a bug on the endpoint slices mirroring controller where endpoint NotReadyAddresses were mirrored as Ready to the corresponding EndpointSlice (#102683, @aojea) [SIG Apps and Network]
• Fix a bug that a preemptor pod may exist as a phantom in the scheduler. (#102498, @Huang-Wei) [SIG Scheduling]
• Fix errors when accessing Windows container stats for Dockershim (#98510, @jsturtevant) [SIG Node and Windows]
• Fix removing pods from podTopologyHints mapping (#101896, @aheng-ch) [SIG Node]
• Fix: avoid nil-pointer panic when checking the frontend IP configuration (#101739, @nilo19) [SIG Cloud Provider]
• Fix: delete non existing disk issue (#102083, @andyzhangx) [SIG Cloud Provider]
• Fixed false-positive uncertain volume attachments, which led to unexpected detachment of CSI migrated volumes (#101737, @Jiawei0227) [SIG Apps and Storage]
• Fixed garbage collection of dangling VolumeAttachments for PersistentVolumes migrated to CSI on startup of kube-controller-manager. (#102176, @timebertt) [SIG Apps and Storage]
• Improve speed of vSphere PV provisioning and reduce number of API calls (#102350, @gnufied) [SIG Cloud Provider and Storage]
• Kubeadm: remove the "ephemeral_storage" request from the etcd static pod that kubeadm deploys on stacked etcd control plane nodes. This request has caused sporadic failures on some setups due to a problem in the kubelet with cadvisor and the LocalStorageCapacityIsolation feature gate. See this issue for more details: https://github.com/kubernetes/kubernetes/issues/99305 (#102673, @jackfrancis) [SIG Cluster Lifecycle]
• Register/Deregister Targets in chunks for AWS TargetGroup (#101592, @M00nF1sh) [SIG Cloud Provider]
• Respect annotation size limit for server-side apply updates to the client-side apply annotation. Also, fix opt-out of this behavior by setting the client-side apply annotation to the empty string. (#102105, @julianvmodesto) [SIG API Machinery]
• Reverted the previous fix for portforward cleanup because it introduced a kubelet regression which can lead into segmentation faults. (#102586, @saschagrunert) [SIG API Machinery and Node]
• ServiceOwnsFrontendIP shouldn't report error when the public IP doesn't match (#102516, @nilo19) [SIG Cloud Provider]

Other (Cleanup or Flake)

• Update the Debian images to pick up CVE fixes in the base images:
  • Update the debian-base image to v1.7.0
  • Update the debian-iptables image to v1.6.1 (#102341, @cpanato) [SIG API Machinery and Testing]
