Full Release Notes

## VLESS Reverse Proxy: Transfer real Source & Local (IP & port), enabled by default https://github.com/XTLS/Xray-core/pull/5101#issuecomment-3404979909

### 本次重点更新内容：

1. **VLESS Reverse Proxy 默认加了传递公网端的 Source & Local (IP & port) 到内网端，详见 https://github.com/XTLS/Xray-core/pull/5101#issuecomment-3404979909**
2. **升级了 uTLS 库以修复 Chrome 指纹的问题，客户端应当尽快升级，详见 https://github.com/XTLS/Xray-core/issues/5230#issuecomment-3402916702**
3. 看到很多小白不会配置 XHTTP XMUX 还抱怨测速不理想，索性把 `maxConcurrency` 默认改为了 1 试试
4. @KobeArthurScofield 参考 VLESS 出站简化了所有协议的出站配置，并且现在每个出站只能有一个 end point 和 user
