Important changes

Rewritten DNS

  • added DNS Over TLS and QUIC support

example:

tls://dns.google
quic://dns.adguard.com

All available DNS schemes:

tcp
tcp+local
udp
udp+local
tls
tls+local
https
https+local
quic
quic+local
  • multiple DNS now share the cache.
  • concurrent query support
{
  "dns": [
    {
      "address": "tls://1.0.0.1",
      "concurrency": true
    }
  ]
}

Other

  • concurrency option for outbound observation
{
  "observatory": {
    "enableConcurrency": true
  }
}
  • DNS sniffer
{
  "routing": {
    "rules": [
      {
        "type": "field",
        "protocol": "dns",
        "outbound": "dns-out"
      }
    ]
  }
}
  • disableExpire dns option
{
  "dns": {
    "disableExpire": true
  }
}
  • removed FakeDNS
FakeDNS is a bad idea, and v2ray's current implementation
causes memory leaks, whether enabled or not.
  • wireguard outbound
WireGuard outbound supports proxy ping requests.

    {
      "protocol": "shadowsocks",
      "settings": {
        ...
      },
      "domainStrategy": "AsIs/UseIP/UseIPv[4/6]/PreferIPv[4/6]"

          }
        ]
      }
    }

  • shadowsocks SIP003 plugin
{
  "outbounds": [
    {
      "protocol": "shadowsocks",
      "settings": {
        ...
        "plugin": "path to plugin",
        "pluginOpts": "args;args2",
        "pluginArgs": [
          "--arg1=true"
        ]
      }
    }
  ]
}
  • embed v2ray-plugin for shadowsocks
{
  "outbounds": [
    {
      "protocol": "shadowsocks",
      "settings": {
        ...
        "plugin": "v2ray-plugin",
        "pluginOpts": "host=shadow.v2fly.org"
      }
    }
  ]
}
  • trojan_sing outbound

high performance trojan outbound.

notice: only the origin trojan (tls) protocol is supported.

{
  "outbounds": [
    {
      "protocol": "trojan_sing",
      "settings": {
        "address": "my.address",
        "serverName": "my.domain",
        "port": 443,
        "password": "my password",
        "insecure": false
      }
    }
  ]
}
  • route only sniffing option
Allows the sniffed domain to be used for routing only, 
without overriding the destination address. 
This improves the routing accuracy of AsIs, 
and provides the expected connection behavior of the client 
(not resolving the domain name again on the server side)

{
  "inbounds": [
    {
      ...
      "sniffing": {
        "destOverride": [
          "http",
          "tls",
          "quic"
        ],
        "enabled": true,
        "routeOnly": true
      },
      "tag": "socks"
    }
  ]
}
  • endpoint independent mapping support (aka full cone NAT)

for protocols other than v*ess, no configuration is required.

{
  "outbounds": [
    {
      "protocol": "v[m/l]ess",
      "settings": {
        "vnext": ...,
        "packetEncoding": "[none/packet/xudp]"
        // none: disabled
        // packet: requires v2ray/v2ray-core v5.0.2+ or SagerNet/v2ray-core
        // xudp: requires XTLS/Xray-core or SagerNet/v2ray-core
      },
      "mux": {
        "enabled": true,
        "packetEncoding": "[none/packet/xudp]"
        // packetEncoding for mux
      }
    }
  ]
}
  • ping proxy support
{
  "ping": {
    "protocol": "<default/unprivileged>",
    "gateway4": "<0.0.0.0>",
    "gateway6": "<::>",
    "disableIPv6": true
  }
}

protocol: udp connection with port 7.

  • XTLS protocol compatibility for vless and trojan

  • gRPC multi/raw mode
