- Kubeadm: removed the integrated support for flex-volumes in kubeadm. Users were advised to migrate away from flex-volumes as recommended by SIG Storage, since 1.22. If kubeadm users wish to continue using the feature, they would need a custom image for the KCM that is not based...

- Make EBS volume expansion faster ([#66728](https://github.com/kubernetes/kubernetes/pull/66728), [@gnufied](https://github.com/gnufied))
- Remove unused binary and container image for kube-aggregator. The functionality is already integrated into the kube-apiserver. ([#67157](https://github.com/kubernetes/kubernetes/pull/67157), [@dims](https://github.com/dims))

- Promotes VolumePVCDataSource (Cloning) feature to beta for 1.16 release ([#81792](https://github.com/kubernetes/kubernetes/pull/81792), [@j-griffith](https://github.com/j-griffith))
- Integrated volume limits for in-tree and CSI volumes into one scheduler predicate. ([#77595](https://github.com/kubernetes/kubernetes/pull/77595), [@bertinatto](https://github.com/bertinatto))

## Deprecations and Removals

- API

- kubeadm has graduated `kubeadm alpha phase` commands to `kubeadm init phase`. This means that the phases of creating a control-plane node are now tightly integrated as part of the `init` command. Alpha features, not yet ready for GA are still kept under `kubeadm alpha` and we appreciate feedback on them.

### go1.15.5

go1.15.5 has been integrated into the Kubernetes project as of this release, [including other infrastructure related updates on this effort](https://github.com/kubernetes/kubernetes/pull/95776).

### CSI Volume Snapshot graduates to General Availability

# GraphQL { #graphql }

As **FastAPI** is based on the **ASGI** standard, it's very easy to integrate any **GraphQL** library also compatible with ASGI.

You can combine normal FastAPI *path operations* with GraphQL on the same application.

/// tip

**GraphQL** solves some very specific use cases.

It has **advantages** and **disadvantages** when compared to common **web APIs**.

OkHttp java.net.CookieHandler
=============================

This module integrates OkHttp with `CookieHandler` from `java.net`.
This used to be part of `okhttp-urlconnection`

### Download

```kotlin
testImplementation("com.squareup.okhttp3:okhttp-java-net-cookiehandler:5.3.0")

OkHttp URLConnection
====================

This module integrates OkHttp with `Authenticator` and `CookieHandler` from `java.net`.

This module is obsolete; prefer `okhttp-java-net-cookiejar`.

### Download

```kotlin
testImplementation("com.squareup.okhttp3:okhttp-urlconnection:5.3.0")

MockWebServer for JUnit 4
=========================

This module integrates mockwebserver3.MockWebServer with JUnit 4.

To use, first add this library as a test dependency:

```
testImplementation("com.squareup.okhttp3:mockwebserver3-junit4:5.3.0")
```

Then in tests annotated `@org.junit.Test`, you may declare a field with the `@Rule` annotation:

```
@Rule public final MockWebServerRule serverRule = new MockWebServerRule();
```
