* Update GitHub Actions, use commit from PR for docs preview, not commit from pre-merge. PR [#1761](https://github.com/tiangolo/fastapi/pull/1761).
* Update GitHub Actions, refactor Gitter bot. PR [#1746](https://github.com/tiangolo/fastapi/pull/1746).

## 0.60.0

* Add GitHub Action to watch for missing preview docs and trigger a preview deploy. PR [#1740](https://github.com/tiangolo/fastapi/pull/1740).

    .fastFallback(true)
    .build();
```

 *  New: Change the build from Kotlin-JVM to Kotlin-multiplatform (which includes JVM). Both
    native and JavaScript platforms are unstable preview releases and subject to
    backwards-incompatible changes in forthcoming releases.
 *  Fix: Don't crash loading the public suffix database resource in obfuscated builds.

**How can I mitigate this prior to installing 1.5.5?**

1. Export existing PodSecurityPolicy objects:
  * `kubectl get podsecuritypolicies -o yaml > psp.yaml`
2. Review and delete any PodSecurityPolicy objects you do not want all pod-creating users to be able to use (NOTE: Privileged users that were making use of those policies will also lose access to those policies). For example:

使用 Linux 容器有几个优点，包括**安全性**、**可复制性**、**简单性**等。

- **Security**
  - Increased pod-level security granularity (eg: Container Image Policies, AppArmor and `sysctl` support)
  - Increased cluster-level security granularity (eg: Access Review API)

## Features

- DRA device taints: `DeviceTaintRule` status provides information about the rule, including whether Pods still need to be evicted (`EvictionInProgress` condition). The newly added `None` effect can be used to preview what a `DeviceTaintRule` would do if it used the `NoExecute` effect and to taint devices (`device health`) without immediately affecting scheduling or running Pods. ([#134152](https://github.com/kubernetes/kubernetes/pull/134152), [@pohly](https:...

- Added feature support to Windows for configuring session affinity of Kubernetes services.
