+## Recent Changes
+
+**2025-02-14**
+- **Bandwidth Limiting (QoS)** - Per-tunnel bandwidth control with token bucket algorithm, server enforces `min(client, server)` as effective limit
+- **Transport Protocol Control** - Support independent configuration for service domain and tunnel domain
+
+```bash
+# Client: limit to 1MB/s
+drip http 3000 --bandwidth 1M
+```
+
+```yaml
+# Server: global limit (config.yaml)
+bandwidth: 10M
+burst_multiplier: 2.5
+```

+## 最近更新
+
+**2025-02-14**
+- **带宽限速 (QoS)** - 基于令牌桶算法的隧道级带宽控制，服务端取 `min(客户端, 服务端)` 作为生效带宽
+- **传输协议控制** - 支持服务域名与隧道域名独立配置
+
+```bash
+# 客户端：限速 1MB/s
+drip http 3000 --bandwidth 1M
+```
+
+```yaml
+# 服务端：全局限速 (config.yaml)
