 ### New
 
-* Server Plugin supports HTTPS.
+* Added config `bandwidth_limit_mode` in frpc, default value is `client` which is current behavior. Optional value is `server`, to enable bandwidth limit in server. The major aim is to let server plugin has the ability to modify bandwidth limit for each proxy.
 
-### Fix
+### Improve
 
-* Fix IPv6 address parse problem.
-* HTTP type proxy can't handle websocket protocol due to error `Connection` header value.
+* `dns_server` supports ipv6.
+* frpc supports graceful shutdown for protocol `quic`.

-### 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

-### frps 中插件配置
-
-```ini
-[common]
-bind_port = 7000
-
-[plugin.user-manager]
-addr = 127.0.0.1:9000
-path = /handler
-ops = Login
-
-[plugin.port-manager]
-addr = 127.0.0.1:9001
-path = /handler
-ops = NewProxy
-```
-
-addr: 插件监听的网络地址。
-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。
-
-```
-# frpc.ini
-[common]
-server_addr = 127.0.0.1
-server_port = 7000
-user = fake
-meta_token = fake
-meta_version = 1.0.0
-
-[ssh]
-type = tcp
-local_port = 22
-remote_port = 6000
-meta_id = 123

+So far, there is no mature Go project that does well in parsing `*.ini` files. 
+
+By comparison, we have selected an open source project: `https://github.com/go-ini/ini`.
+
+This library helped us solve most of the key-value matching, but there are still some problems, such as not supporting parsing `map`.
+
+We add our own logic on the basis of this library. In the current situationwhich, we need to complete the entire `Unmarshal` in two steps:
+
+* Step#1, use `go-ini` to complete the basic parameter matching;
+* Step#2, parse our custom parameters to realize parsing special structure, like `map`, `array`.
+
+Some of the keywords in `tag`(like inline, extends, etc.) may be different from standard libraries such as `json` and `protobuf` in Go. For details, please refer to the library documentation: https://ini.unknwon.io/docs/intro.
