+We are excited to announce the v0.5.0 release of Gateway API. For the first
+time, several of our most important Gateway API resources are graduating to
+beta. Additionally, we are starting a new initiative to explore how Gateway API
+can be used for mesh and introducing new experimental concepts such as URL
+rewrites. We'll cover all of this and more below. 
+-->
+我们很高兴地宣布 Gateway API 的 v0.5.0 版本发布。
+我们最重要的几个 Gateway API 资源首次进入 Beta 阶段。
+此外，我们正在启动一项新的倡议，探索如何将 Gateway API 用于网格，还引入了 URL 重写等新的实验性概念。
+下文涵盖了这部分内容和更多说明。
+
+<!-- 
+## What is Gateway API? 
+-->
+## 什么是 Gateway API？
+
+<!-- 
+Gateway API is a collection of resources centered around [Gateway][gw] resources
+(which represent the underlying network gateways / proxy servers) to enable
+robust Kubernetes service networking through expressive, extensible and
+role-oriented interfaces that are implemented by many vendors and have broad
+industry support. 
+-->
+Gateway API 是以 [Gateway][gw] 资源（代表底层网络网关/代理服务器）为中心的资源集合，
+Kubernetes 服务网络的健壮性得益于众多供应商实现、得到广泛行业支持且极具表达力、可扩展和面向角色的各个接口。
+
+<!-- 
+Originally conceived as a successor to the well known [Ingress][ing] API, the
+benefits of Gateway API include (but are not limited to) explicit support for
+many commonly used networking protocols (e.g. `HTTP`, `TLS`, `TCP`, `UDP`) as
+well as tightly integrated support for Transport Layer Security (TLS). The
+`Gateway` resource in particular enables implementations to manage the lifecycle
+of network gateways as a Kubernetes API. 
+-->
+Gateway API 最初被认为是知名 [Ingress][ing] API 的继任者，
+Gateway API 的好处包括（但不限于）对许多常用网络协议的显式支持
+（例如 `HTTP`、`TLS`、`TCP `、`UDP`) 以及对传输层安全 (TLS) 的紧密集成支持。
+特别是 `Gateway` 资源能够实现作为 Kubernetes API 来管理网络网关的生命周期。
+
+<!-- 
+If you're an end-user interested in some of the benefits of Gateway API we
+invite you to jump in and find an implementation that suits you. At the time of
+this release there are over a dozen [implementations][impl] for popular API
+gateways and service meshes and guides are available to start exploring quickly. 
+-->
+如果你是对 Gateway API 的某些优势感兴趣的终端用户，我们邀请你加入并找到适合你的实现方式。
+值此版本发布之时，对于流行的 API 网关和服务网格有十多种[实现][impl]，还提供了操作指南便于快速开始探索。

+### Getting started 
+-->
+### 入门
+
+<!-- 
+Gateway API is an official Kubernetes API like
+[Ingress](https://kubernetes.io/docs/concepts/services-networking/ingress/).
+Gateway API represents a superset of Ingress functionality, enabling more
+advanced concepts. Similar to Ingress, there is no default implementation of
+Gateway API built into Kubernetes. Instead, there are many different
+[implementations][impl] available, providing significant choice in terms of underlying
+technologies while providing a consistent and portable experience. 
+-->
+Gateway API 是一个类似 [Ingress](/zh-cn/docs/concepts/services-networking/ingress/)
+的正式 Kubernetes API。Gateway API 代表了 Ingress 功能的一个父集，使得一些更高级的概念成为可能。
+与 Ingress 类似，Kubernetes 中没有内置 Gateway API 的默认实现。
+相反，有许多不同的[实现][impl]可用，在提供一致且可移植体验的同时，还在底层技术方面提供了重要的选择。
+
+<!-- 
+Take a look at the [API concepts documentation][concepts] and check out some of
+the [Guides][guides] to start familiarizing yourself with the APIs and how they
+work. When you're ready for a practical application open the [implementations
+page][impl] and select an implementation that belongs to an existing technology
+you may already be familiar with or the one your cluster provider uses as a
+default (if applicable). Gateway API is a [Custom Resource Definition
+(CRD)][crd] based API so you'll need to [install the CRDs][install-crds] onto a
+cluster to use the API. 
+-->
+查看 [API 概念文档][concepts] 并查阅一些[指南][guides]以开始熟悉这些 API 及其工作方式。
+当你准备好一个实用的应用程序时，
+请打开[实现页面][impl]并选择属于你可能已经熟悉的现有技术或集群提供商默认使用的技术（如果适用）的实现。
+Gateway API 是一个基于 [CRD][crd] 的 API，因此你将需要[安装 CRD][install-crds] 到集群上才能使用该 API。
+
+<!-- 
+If you're specifically interested in helping to contribute to Gateway API, we
+would love to have you! Please feel free to [open a new issue][issue] on the
+repository, or join in the [discussions][disc]. Also check out the [community
+page][community] which includes links to the Slack channel and community meetings.
