 ## 1.更新信息
+2025.11.12 v1.3.1 1. Reality Configuration Update: In Reality configurations, the original multiplexing (multiplex) has been replaced with xtls-rprx-vision flow control, improving transmission efficiency, reducing latency, and enhancing security. The original configuration conversion script command remains fully compatible and unchanged — `bash <(curl -sSL https://raw.githubusercontent.com/fscarmen/tools/main/vision.sh)`; 2. Quick Install Mode: Added a one-click installation feature that auto-fills all parameters, simplifying the deployment process. Chinese users can use -l or -L; English users can use -k or -K. Case-insensitive support makes operations more flexible; 3. Custom Reality Key Support: In response to user feedback, you can now specify a custom Reality private key via --REALITY_PRIVATE=<privateKey>. The script will automatically compute the corresponding public key using the integrated API. If left blank, it generates a random private-public key pair in real-time; 4. Enhanced HTTP + Reality Support in Clash Clients: Added full compatibility for HTTP + Reality transport in Clash clients, improving connection stability and performance; 1. Reality 配置变更：在 Reality 配置中，将原来的多路复用（multiplex）替换为 xtls-rprx-vision 流控，提升传输效率、降低延迟并增强安全性。原配置转换脚本命令—— `bash <(curl -sSL https://raw.githubusercontent.com/fscarmen/tools/main/vision.sh)` ; 2. 极速安装模式：新增一键安装功能，所有参数自动填充，简化部署流程。中文用户使用 -l 或 -L，英文用户使用 -k 或 -K，大小写均支持，操作更灵; 3. 自定义 Reality 密钥支持：响应用户反馈，现支持通过 --REALITY_PRIVATE=<privateKey> 指定自定义 Reality 私钥，脚本将调用相关 API 自动计算对应公钥。若留空，则实时生成随机公私钥; 4. HTTP + Reality 在 Clash 客户端的增强支持：补充了对 Clash 客户端中 HTTP + Reality 传输方式的完整兼容，提升了连接稳定性和性能
