## Changelog since v1.21.0-alpha.2
## Urgent Upgrade Notes
### (No, really, you MUST read this before you upgrade)
- Newly provisioned PVs by gce-pd will no longer have the beta FailureDomain label. gce-pd volume plugin will start to have GA topology label instead. ([#98700](https://github.com/kubernetes/kubernetes/pull/98700), [@Jiawei0227](https://github.com/Jiawei0227)) [SIG Cloud Provider, Storage and Testing]
- Remove alpha CSIMigrationXXComplete flag and add alpha InTreePluginXXUnregister flag. Deprecate CSIMigrationvSphereComplete flag and it will be removed in 1.22. ([#98243](https://github.com/kubernetes/kubernetes/pull/98243), [@Jiawei0227](https://github.com/Jiawei0227)) [SIG Node and Storage]
## Changes by Kind
### API Change
- Adds support for portRange / EndPort in Network Policy ([#97058](https://github.com/kubernetes/kubernetes/pull/97058), [@rikatz](https://github.com/rikatz)) [SIG Apps and Network]

- Scheduler extender filter interface now can report unresolvable failed nodes in the new field `FailedAndUnresolvableNodes` of `ExtenderFilterResult` struct. Nodes in this map will be skipped in the preemption phase. ([#92866](https://github.com/kubernetes/kubernetes/pull/92866), [@cofyc](https://github.com/cofyc)) [SIG Scheduling]
### Feature
- A lease can only attach up to 10k objects. ([#98257](https://github.com/kubernetes/kubernetes/pull/98257), [@lingsamuel](https://github.com/lingsamuel)) [SIG API Machinery]
- Add ignore-errors flag for drain, support none-break drain in group ([#98203](https://github.com/kubernetes/kubernetes/pull/98203), [@yuzhiquan](https://github.com/yuzhiquan)) [SIG CLI]
- Base-images: Update to debian-iptables:buster-v1.4.0
- Uses iptables 1.8.5
- base-images: Update to debian-base:buster-v1.3.0
- cluster/images/etcd: Build etcd:3.4.13-2 image
- Uses debian-base:buster-v1.3.0 ([#98401](https://github.com/kubernetes/kubernetes/pull/98401), [@pacoxu](https://github.com/pacoxu)) [SIG Testing]
- Export NewDebuggingRoundTripper function and DebugLevel options in the k8s.io/client-go/transport package. ([#98324](https://github.com/kubernetes/kubernetes/pull/98324), [@atosatto](https://github.com/atosatto)) [SIG API Machinery]
- Kubectl wait ensures that observedGeneration >= generation if applicable ([#97408](https://github.com/kubernetes/kubernetes/pull/97408), [@KnicKnic](https://github.com/KnicKnic)) [SIG CLI]
- Kubernetes is now built using go1.15.8 ([#98834](https://github.com/kubernetes/kubernetes/pull/98834), [@cpanato](https://github.com/cpanato)) [SIG Cloud Provider, Instrumentation, Release and Testing]
- New admission controller "denyserviceexternalips" is available. Clusters which do not *need- the Service "externalIPs" feature should enable this controller and be more secure. ([#97395](https://github.com/kubernetes/kubernetes/pull/97395), [@thockin](https://github.com/thockin)) [SIG API Machinery]
- Overall, enable the feature of `PreferNominatedNode` will improve the performance of scheduling where preemption might frequently happen, but in theory, enable the feature of `PreferNominatedNode`, the pod might not be scheduled to the best candidate node in the cluster. ([#93179](https://github.com/kubernetes/kubernetes/pull/93179), [@chendave](https://github.com/chendave)) [SIG Scheduling and Testing]
- Pause image upgraded to 3.4.1 in kubelet and kubeadm for both Linux and Windows. ([#98205](https://github.com/kubernetes/kubernetes/pull/98205), [@pacoxu](https://github.com/pacoxu)) [SIG CLI, Cloud Provider, Cluster Lifecycle, Node, Testing and Windows]

([#98553](https://github.com/kubernetes/kubernetes/pull/98553), [@mtaufen](https://github.com/mtaufen)) [SIG API Machinery, Auth and Testing]
### Documentation
- Feat: azure file migration go beta in 1.21. Feature gates CSIMigration to Beta (on by default) and CSIMigrationAzureFile to Beta (off by default since it requires installation of the AzureFile CSI Driver)
The in-tree AzureFile plugin "kubernetes.io/azure-file" is now deprecated and will be removed in 1.23. Users should enable CSIMigration + CSIMigrationAzureFile features and install the AzureFile CSI Driver (https://github.com/kubernetes-sigs/azurefile-csi-driver) to avoid disruption to existing Pod and PVC objects at that time.
Users should start using the AzureFile CSI Driver directly for any new volumes. ([#96293](https://github.com/kubernetes/kubernetes/pull/96293), [@andyzhangx](https://github.com/andyzhangx)) [SIG Cloud Provider]
### Failing Test
- Kubelet: the HostPort implementation in dockershim was not taking into consideration the HostIP field, causing that the same HostPort can not be used with different IP addresses.
This bug causes the conformance test "HostPort validates that there is no conflict between pods with same hostPort but different hostIP and protocol" to fail. ([#98755](https://github.com/kubernetes/kubernetes/pull/98755), [@aojea](https://github.com/aojea)) [SIG Cloud Provider, Network and Node]

- Fixed a bug that on k8s nodes, when the policy of INPUT chain in filter table is not ACCEPT, healthcheck nodeport would not work.
Added iptables rules to allow healthcheck nodeport traffic. ([#97824](https://github.com/kubernetes/kubernetes/pull/97824), [@hanlins](https://github.com/hanlins)) [SIG Network]
- Fixed kube-proxy container image architecture for non amd64 images. ([#98526](https://github.com/kubernetes/kubernetes/pull/98526), [@saschagrunert](https://github.com/saschagrunert)) [SIG API Machinery, Release and Testing]
- Fixed provisioning of Cinder volumes migrated to CSI when StorageClass with AllowedTopologies was used. ([#98311](https://github.com/kubernetes/kubernetes/pull/98311), [@jsafrane](https://github.com/jsafrane)) [SIG Storage]
- Fixes a panic in the disruption budget controller for PDB objects with invalid selectors ([#98750](https://github.com/kubernetes/kubernetes/pull/98750), [@mortent](https://github.com/mortent)) [SIG Apps]

- If the user specifies an invalid timeout in the request URL, the request will be aborted with an HTTP 400.
- in cases where the client specifies a timeout in the request URL, the overall request deadline is shortened now since the deadline is setup as soon as the request is received by the apiserver. ([#96901](https://github.com/kubernetes/kubernetes/pull/96901), [@tkashem](https://github.com/tkashem)) [SIG API Machinery and Testing]

([#98728](https://github.com/kubernetes/kubernetes/pull/98728), [@stmcginnis](https://github.com/stmcginnis)) [SIG Cluster Lifecycle]
- Kubeadm: fix a bug where external credentials in an existing admin.conf prevented the CA certificate to be written in the cluster-info ConfigMap. ([#98882](https://github.com/kubernetes/kubernetes/pull/98882), [@kvaps](https://github.com/kvaps)) [SIG Cluster Lifecycle]
- Kubeadm: fix bad token placeholder text in "config print *-defaults --help" ([#98839](https://github.com/kubernetes/kubernetes/pull/98839), [@Mattias-](https://github.com/Mattias-)) [SIG Cluster Lifecycle]
- Kubeadm: get k8s CI version markers from k8s infra bucket ([#98836](https://github.com/kubernetes/kubernetes/pull/98836), [@hasheddan](https://github.com/hasheddan)) [SIG Cluster Lifecycle and Release]

- We will no longer automatically delete all data when a failure is detected during creation of the volume data file on a CSI volume. Now we will only remove the data file and volume path. ([#96021](https://github.com/kubernetes/kubernetes/pull/96021), [@huffmanca](https://github.com/huffmanca)) [SIG Storage]
### Other (Cleanup or Flake)
- Fix the description of command line flags that can override --config ([#98254](https://github.com/kubernetes/kubernetes/pull/98254), [@changshuchao](https://github.com/changshuchao)) [SIG Scheduling]
- Migrate scheduler/taint_manager.go structured logging ([#98259](https://github.com/kubernetes/kubernetes/pull/98259), [@tanjing2020](https://github.com/tanjing2020)) [SIG Apps]
- Migrate staging/src/k8s.io/apiserver/pkg/admission logs to structured logging ([#98138](https://github.com/kubernetes/kubernetes/pull/98138), [@lala123912](https://github.com/lala123912)) [SIG API Machinery]
- Resolves flakes in the Ingress conformance tests due to conflicts with controllers updating the Ingress object ([#98430](https://github.com/kubernetes/kubernetes/pull/98430), [@liggitt](https://github.com/liggitt)) [SIG Network and Testing]
- The default delegating authorization options now allow unauthenticated access to healthz, readyz, and livez. A system:masters user connecting to an authz delegator will not perform an authz check. ([#98325](https://github.com/kubernetes/kubernetes/pull/98325), [@deads2k](https://github.com/deads2k)) [SIG API Machinery, Auth, Cloud Provider and Scheduling]
- The e2e suite can be instructed not to wait for pods in kube-system to be ready or for all nodes to be ready by passing `--allowed-not-ready-nodes=-1` when invoking the e2e.test program. This allows callers to run subsets of the e2e suite in scenarios other than perfectly healthy clusters. ([#98781](https://github.com/kubernetes/kubernetes/pull/98781), [@smarterclayton](https://github.com/smarterclayton)) [SIG Testing]
- The feature gates `WindowsGMSA` and `WindowsRunAsUserName` that are GA since v1.18 are now removed. ([#96531](https://github.com/kubernetes/kubernetes/pull/96531), [@ialidzhikov](https://github.com/ialidzhikov)) [SIG Node and Windows]
- The new `-gce-zones` flag on the `e2e.test` binary instructs tests that check for information about how the cluster interacts with the cloud to limit their queries to the provided zone list. If not specified, the current behavior of asking the cloud provider for all available zones in multi zone clusters is preserved.
