⚠️ Do NOT use this release. ⚠️ Bugs are fixed in v4.36.2

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
  • Thanks @DuckSoft, @xiaokangwang, @RPRX, @kslr, @maskedeken and an anonymous contributor.
• 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 modded outbound address and dokodemo-door setup while using less system resources. (#770)
  • Docs: Loopback
  • Thanks @xiaokangwang @kslr
• Routing: add a faster and more memory-efficient routing rule matcher MphDomainMatcher that uses minimal perfect hash. (#743)

4. The cache of V2Ray's internal DNS can be disabled now(#699). Document for DNS is updated. Thanks @CalmLong.
5. You can disable compatibility for legacy VMess MD5(#596). Document for VMess have been updated. From Jan 1, 2022, compatibility for legacy VMess MD5 will be disabled by default. Thanks @dyhkwong.
6. You can now completely disable VMess's content encryption and protection, and may achieve better performance than none pseudo encryption. The document for VMess is updated. This is a non-breaking change on client side.
