AI Summary

REALITY post-handshake record detection to fix Aparecium detection tool issues and performance fixes.

Key Highlights

  • REALITY now detects and imitates target's post-handshake records (NewSessionTicket) to prevent detection.
  • REALITY server now uses AES-NI hardware acceleration to fix performance issues.
  • DNS module received new features like `disableCache`, `finalQuery`, and `unexpectedIPs`.

New Features

  • REALITY post-handshake record imitation
  • DNS new features (disableCache, finalQuery, unexpectedIPs)
  • Happy Eyeballs (RFC 8305) support
  • REALITY AES-NI hardware acceleration

Full Release Notes

## REALITY practice: Detect & imitate target's post-handshake records

https://github.com/XTLS/Xray-core/issues/4778 提到 @ban6cat6 发布了检测工具 [Aparecium](https://github.com/ban6cat6/aparecium)，通过检测“未模仿 OpenSSL 握手后发的两个 `NewSessionTicket`”来检测 REALITY、ShadowTLS 等可以“偷别人”的协议，对此，Xray 团队迅速响应，研究并着手修复该问题

**该版本 REALITY 服务端启动后会自动用 Chrome 指纹探测 target 的 post-handshake records 长度，耗时半分钟左右（期间会阻塞代理请求），并在后续的 REALITY 连接中模仿发送这些 records，从而初步修复了上述问题，请大家尽快升级服务端**

再次感谢 @ban6cat6 的发现，与此同时，Xray 团队对这类问题的响应与修复速度也非常值得骄傲

该版本还重点修复了上个版本中 REALITY 服务端未用上 AES-NI 硬件加速导致性能下降的问题 https://github.com/XTLS/Xray-core/issues/4741 ，以及合并了 [REALITY 回落限速](https://github.com/XTLS/Xray-core/pull/4553)、[Docker 镜像重构](https://github.com/XTLS/Xray-core/pull/4738)、[Happy Eyeballs](https://github.com/XTLS/Xray-core/pull/4667)、[DNS New Features](https://github.com/XTLS/Xray-core/pull/4666) 等重要 PR，[Serverless-for-Iran](https://github.com/XTLS/Xray-examples/tree/main/Serverless-for-Iran) 预计会有更新
