Xray-core v26.1.23 | Github List

Proxy: Add TUN inbound for Windows & Linux, including Android https://github.com/XTLS/Xray-core/pull/5464 https://github.com/XTLS/Xray-core/pull/5509 & Proxy: Add Hysteria outbound & transport (version 2, udphop) and Salamander udpmask https://github.com/XTLS/Xray-core/pull/5508

新年好！2026 第一版 Xray-core 重点更新内容：

新增 TUN 入站（Windows、Linux、Android、macOS）https://github.com/XTLS/Xray-core/pull/5464 ，默认 UDP FullCone 与 XUDP UoT Migration https://github.com/XTLS/Xray-core/pull/5509
新增 process 路由规则（Windows、Linux），匹配进程名/绝对路径/文件夹，支持任何入站 https://github.com/XTLS/Xray-core/pull/5496
新增 Hysteria 2 出站、Hysteria 2 传输层（支持端口跳跃）、Salamander 伪装层，完整配置示例详见 https://github.com/XTLS/Xray-core/pull/5508
新增“最终伪装层”概念 https://t.me/projectXtls/1354 ，比 TLS/QUIC 更底层，下一步计划 https://github.com/XTLS/Xray-core/pull/5508#issuecomment-3743864399
TLS 客户端使用 pinnedPeerCertSha256 取代原有两项参数 https://github.com/XTLS/Xray-core/pull/5154 https://github.com/XTLS/Xray-core/pull/5532 https://github.com/XTLS/Xray-core/commit/760223ad70f822fcb859a217e60e038a970610f9 ，分享链接标准 https://github.com/XTLS/Xray-core/discussions/716 已更新 pcs
REALITY 客户端收到目标网站的真证书时打印出更加明确的警报（potential MITM or redirection）https://github.com/XTLS/Xray-core/pull/5427
为废弃特性/过时协议提醒迁移 https://github.com/XTLS/Xray-core/commit/cd8aab9544bc35fbc9990f61cb3613d0abbbe775 ，创建了 SECURITY.md https://github.com/XTLS/Xray-core/commit/1cf5662949aa32cebeb0f3ae79564819374ced7a 以明确安全漏洞/协议识别问题提交途径

为了使用 TUN，配置文件需要以下修改，以 Windows 为例：

配置文件加一个 "tun" 入站，无需 settings，加一个 "direct" 作为默认出站
为所有出站设置 sockopt "interface": "WLAN" 或 "以太网" 防止出站回流 Xray-core
设置 routing 比如 "process": ["NatTypeTester.exe"] 导向代理协议出站
浏览器会有 QUIC，注意设置路由 block UDP/443，或为 sniffing 启用 "quic"

TUN 尚未支持“自动修改系统路由表”，目前需要手动设置：

以管理员权限启动 Xray-core，静置数秒等 Windows 自动为 TUN 分配 IP
执行 ipconfig 与 route print 查看 Xray TUN 的 IPv4 地址与 interface ID
以管理员权限执行 route add 0.0.0.0 mask 0.0.0.0 *.*.*.* if ** 新增系统路由

感谢 @Owersun @yuhan6665 @Fangliding @KobeArthurScofield @RPRX @osypai 为支持 TUN 所作出的贡献！

@Meo597 将 https://xtls.github.io/ 升级至了 VitePress，本次更新内容也会陆续更新至文档中

由于伊朗目前完全断网，致力于内存优化的贡献者 @hossinasaadi 已有半个月没有活动，盼望他早日回归！
