+### Port range mapping
+
+*Added in v0.56.0*
+
+We can use the range syntax of Go template combined with the built-in `parseNumberRangePair` function to achieve port range mapping.
+
+The following example, when run, will create 8 proxies named `test-6000, test-6001 ... test-6007`, each mapping the remote port to the local port.
+
+```
+{{- range $_, $v := parseNumberRangePair "6000-6006,6007" "6000-6006,6007" }}
+[[proxies]]
+name = "tcp-{{ $v.First }}"
+type = "tcp"
+localPort = {{ $v.First }}
+remotePort = {{ $v.Second }}
+{{- end }}
+```
+
 ### Client Plugins
 
 frpc only forwards requests to local TCP or UDP ports by default.

-No feature changes, just a fix for the issue of no released assets in version 0.55.0.
+### Features
+
+* Support range ports mapping in TOML/YAML/JSON configuration file by using go template syntax.
+
+  For example:
+
+  ```
+  {{- range $_, $v := parseNumberRangePair "6000-6006,6007" "6000-6006,6007" }}
+  [[proxies]]
+  name = "tcp-{{ $v.First }}"
+  type = "tcp"
+  localPort = {{ $v.First }}
+  remotePort = {{ $v.Second }}
+  {{- end }}
+  ```
+
+  This will create 8 proxies such as `tcp-6000, tcp-6001, ... tcp-6007`.
+
+* Health check supports custom request headers.
+* Enable compatibility mode for the Android system to solve the issues of incorrect log time caused by time zone problems and default DNS resolution failures.
+
+### Fixes
+
+* Fix the issue of incorrect interval time for rotating the log by day.
+* Disable quic-go's ECN support by default. It may cause issues on certain operating systems.
