 ## 为什么使用 frp ？
 
 通过在具有公网 IP 的节点上部署 frp 服务端，可以轻松地将内网服务穿透到公网，同时提供诸多专业的功能特性，这包括：
 
-* 客户端服务端通信支持 TCP、KCP 以及 Websocket 等多种协议。
-* 采用 TCP 连接流式复用，在单个连接间承载更多请求，节省连接建立时间。
+* 客户端服务端通信支持 TCP、QUIC、KCP 以及 Websocket 等多种协议。
+* 采用 TCP 连接流式复用，在单个连接间承载更多请求，节省连接建立时间，降低请求延迟。
 * 代理组间的负载均衡。
 * 端口复用，多个服务通过同一个服务端端口暴露。
-* 多个原生支持的客户端插件（静态文件查看，HTTP、SOCK5 代理等），便于独立使用 frp 客户端完成某些工作。
-* 高度扩展性的服务端插件系统，方便结合自身需求进行功能扩展。
+* 支持 P2P 通信，流量不经过服务器中转，充分利用带宽资源。
+* 多个原生支持的客户端插件（静态文件查看，HTTPS/HTTP 协议转换，HTTP、SOCK5 代理等），便于独立使用 frp 客户端完成某些工作。
+* 高度扩展性的服务端插件系统，易于结合自身需求进行功能扩展。
 * 服务端和客户端 UI 页面。

+我们正在进行 v2 大版本的开发，将会尝试在各个方面进行重构和升级，且不会与 v1 版本进行兼容，预计会持续较长的一段时间。
+
+现在的 v0 版本将会在合适的时间切换为 v1 版本并且保证兼容性，后续只做 bug 修复和优化，不再进行大的功能性更新。
+
+### 关于 v2 的一些说明
+
+v2 版本的复杂度和难度比我们预期的要高得多。我只能利用零散的时间进行开发，而且由于上下文经常被打断，效率极低。由于这种情况可能会持续一段时间，我们仍然会在当前版本上进行一些优化和迭代，直到我们有更多空闲时间来推进大版本的重构，或者也有可能放弃一次性的重构，而是采用渐进的方式在当前版本上逐步做一些可能会导致不兼容的修改。
+
+v2 的构想是基于我多年在云原生领域，特别是在 K8s 和 ServiceMesh 方面的工作经验和思考。它的核心是一个现代化的四层和七层代理，类似于 envoy。这个代理本身高度可扩展，不仅可以用于实现内网穿透的功能，还可以应用于更多领域。在这个高度可扩展的内核基础上，我们将实现 frp v1 中的所有功能，并且能够以一种更加优雅的方式实现原先架构中无法实现或不易实现的功能。同时，我们将保持高效的开发和迭代能力。
+
+除此之外，我希望 frp 本身也成为一个高度可扩展的系统和平台，就像我们可以基于 K8s 提供一系列扩展能力一样。在 K8s 上，我们可以根据企业需求进行定制化开发，例如使用 CRD、controller 模式、webhook、CSI 和 CNI 等。在 frp v1 中，我们引入了服务端插件的概念，实现了一些简单的扩展性。但是，它实际上依赖于简单的 HTTP 协议，并且需要用户自己启动独立的进程和管理。这种方式远远不够灵活和方便，而且现实世界的需求千差万别，我们不能期望一个由少数人维护的非营利性开源项目能够满足所有人的需求。
+
+最后，我们意识到像配置管理、权限验证、证书管理和管理 API 等模块的当前设计并不够现代化。尽管我们可能在 v1 版本中进行一些优化，但确保兼容性是一个令人头疼的问题，需要投入大量精力来解决。
+
+非常感谢您对 frp 的支持。

-Metadata entries under `[common]` will be sent in `Login` under the key `metas`, and in any other RPC request under `user.metas`.

-### 服务端管理插件
-
-frp 管理插件的作用是在不侵入自身代码的前提下，扩展 frp 服务端的能力。
-
-frp 管理插件会以单独进程的形式运行，并且监听在一个端口上，对外提供 RPC 接口，响应 frps 的请求。
-
-frps 在执行某些操作前，会根据配置向管理插件发送 RPC 请求，根据管理插件的响应来执行相应的操作。
-
-### RPC 请求
-
-管理插件接收到操作请求后，可以给出三种回应。
-
-* 拒绝操作，需要返回拒绝操作的原因。
-* 允许操作，不需要修改操作内容。
-* 允许操作，对操作请求进行修改后，返回修改后的内容。
-
-### 接口
-
-接口路径可以在 frps 配置中为每个插件单独配置，这里以 `/handler` 为例。
-
-Request
-
-```
-POST /handler
-{
-    "version": "0.1.0",
-    "op": "Login",
-    "content": {
-        ... // 具体的操作信息
-    }
-}
-
-请求 Header
-X-Frp-Reqid: 用于追踪请求
-```
-
-Response
-

-
-拒绝执行操作

-允许且内容不需要变动

-    "content": {
-        ... // 替换后的操作信息，格式必须和请求时的一致
-    }

-
-### 操作类型

-path: 插件监听的 HTTP 请求路径。
-ops: 插件需要处理的操作列表，多个 op 以英文逗号分隔。

-### 元数据
-
-为了减少 frps 的代码修改，同时提高管理插件的扩展能力，在 frpc 的配置文件中引入自定义元数据的概念。元数据会在调用 RPC 请求时发送给插件。
-
-元数据以 `meta_` 开头，可以配置多个，元数据分为两种，一种配置在 `common` 下，一种配置在各个 proxy 中。
