v4.32.1 Released

https://github.com/v2fly/v2ray-core/releases/tag/v4.32.1

Important improvement
* VLESS XTLS Direct Mode ReadV Experiment
It's strongly recommended to test this change, as it reaches the best performance of current V2Ray platform.
Remember to use V2Ray v4.32.1+ on at least client side. For more information, please visit

#performance

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。

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:

# h2c
$ grpcurl -plaintext localhost:10086 list
grpc.reflection.v1alpha.ServerReflection
v2ray.core.app.proxyman.command.HandlerService
v2ray.core.app.stats.command.StatsService

# h2 with tls
$ grpcurl -insecure -cert cert.crt -key cert.key localhost:10086 v2ray.core.app.stats.command.StatsService/GetSysStats

Breaking Changes
* Support for the legacy Shadowsocks protocol with stream ciphers has been removed (#566). If you are still using the unsecure stream ciphers, migrate to Shadowsocks AEAD (ChaCha20Poly1305 and AES-GCM) immediately.
* Binaries of the following architectures are no longer a part of the release: s390x, ppc64, ppc64le, mips softfloat.

Changes
* DNS: refactoring DNS (#169)
* DNS: support DNS over QUIC (#534) (currently only non-proxied lookup)
* DNS: add clientIp feature support for every nameserver (#504)
* Release: add Android release (#512)
* Android: default dns set to 8.8.8.8:53 (#572)
* TLS Session Resumption is now disabled by default (#569). See #557 for more information.

* FakeDNS, an imaginary DNS server to preserve the domain information even if the software do not support proxy settings
* HybridDomainMatcher: a faster and more memory-efficient routing rule matcher.
* Outbound transport level proxySettings: comprehensive chained proxy support
* Support Apple Silicon: add pre-built binary for Apple Silicon named v2ray-macos-arm64-v8a.zip

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.

v4.38.0 is released. (Unstable 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.

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.
