+### 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`.
+
 ### Fixes
 
 * Fix the issue of incorrect interval time for rotating the log by day.
