新年快乐

中秋快乐！

v4.38.3 is released. (Stable Release)

This release includes security functionality improvement for some users.

Feature

* FakeDNS: Added fakedns+others sniffer. Thanks yuhan6665 .
* TLS: A SECURITY improvement that allow the remote peer's TLS certificate to be pinned to a known value.
* Observatory: A component that measure the connectivity of selected outbounds.
* Routing : leastPing balancing strategy is added. This strategy will select a outbound that is alive and completed HTTPS GET request in the least time.

Fix

* Fixed crashing in fake dns. Thanks IceCodeNew
* Added IPv6 pool in fake dns by default. Thanks Loyalsoldier
* Return ErrEmptyResponse for fakedns. Thanks sixg0000d
* Fixed UDP DNS connection cause crash. Thanks nekohasekai
* Multi-json support for observatory, browser forwarder. Thanks ha-ku AkinoKaede

Chore

* Fixed two typo in comments. Thanks U-v-U

Security Advisory

* TLS connections with dangerous diagnose option allowInsecure turn on and without certificate pin with pinnedPeerCertificateChainSha256 will not be able protect your data at all from a attacker in privileged network path(for example ISP or any firewall or censorship infrastructure). This is especially dangerous when an unprotected protocol or option is used, such as any VLess configuration, VMess with none or zero security, and any trojan configuration, in which case your data is accessible to attacker in plain text and attacker can inject arbitrary data pretending to the the remote server. In the case of VLess and trojan, the proxy protocol access control credential is also exposed to the attacker, the attacker will be able to use your proxy. You are advised to use certificate pin (and/or other security features provided in a later version of V2Ray) whenever allowInsecure is turned on. Attempting to MITM your connection temporarily to identify TLS based proxy is a known threat.

Features

* Transport: add gRPC / gun transport. This transport's connections can be relayed over Nginx and other supported CDNs, have an ALPN of h2 and a built-in mux. (#757 #783)
-> Docs: Transport; gRPC transport

* Proxy: add loopback proxy. This proxy allows you to send connections back to router to be routed again. It is a drop-in replacement for modified outbound address and dokodemo-door setup while using less system resources. (#770)
-> Docs: Loopback

* Routing: add a faster and more memory-efficient routing rule matcher MphDomainMatcher that uses minimal perfect hash. (#743)
-> Docs: Routing

Fixes

* DNS: Refined DNS default setting logics in Android (#767)
* FakeDNS: use 198.18.0.0/15 as default FakeDNS IP pool (#779)

Notices

* VMess: From Jan 1, 2022, compatibility for legacy VMess MD5 will be disabled by default. Visit here for more information.
* You are able to compile exactly the same binaries as the ones in Assets section below by simply following the compiling guide.

For Downstream Developers

The Go module name of v2ray-core has been changed to github.com/v2fly/v2ray-core/v4. Do NOT use v2ray.com/core anymore.

New API Service: ReflectionService

This service enables the clients to retrieve gRPC service's API list and signatures without prior access to its proto files. In this way, tools like grpcurl could easily interact with the API service:

v2ray.core.app.proxyman.command.HandlerService
v2ray.core.app.stats.command.StatsService

# h2 with tls

最新的 v4.32.1 版本中，VLESS XTLS Direct Mode 引入了 ReadV 增强，减少一层内存 Copy，性能已与 VLESS 无加密裸奔持平（接近于纯流量转发），为传统 VMess WS TLS 方案的五倍、VLESS TCP TLS 的三倍（且测试机器 CPU 均有 AES 指令集，否则差距更大，如硬路由器上），强烈建议测试体验。这或许是当前性能最强的安全代理方式，但并不是上限，因为下一步优化方向是 V2Ray 框架本身的性能。

尽管任何人都可以检查自由开源软件中的源代码是否存在恶意漏洞，但大多数情况下都只是获取这些软件的预编译版本，没有办法确认它们和源代码是否一致。

这就刺激了对发布软件的开发者的攻击 —— 不仅是传统的对漏洞的利用，还以政治影响、勒索甚至暴力威胁的形式。

比起开发者本身，攻击构建程序的基础设施更能控制大量的用户设备，而二进制文件变化，对开发者和用户而言是个共同的盲区。

这些攻击可能还导致特定目标，如异见者，新闻工作者和举报人，以及希望进行自由通信的任何人，可能仅仅因为在专制政权下自由通信而遭受处罚。

因此，Reproducible Builds 允许验证在编译过程中没有漏洞或后门被引入。通过相同的源代码生成相同的二进制，让多个第三方就 "正确" 的结果达成共识，突出任何可疑的和值得仔细检查的偏差。

现在，我们在 https://github.com/v2fly/reproducible-builds 提供该工具，你可以快速运行并校验发布文件是否被修改。
