Notice

Due to increase in size of the geoip.dat file recently, devices with insufficient ROM/RAM are experiencing difficulties in using V2Ray. The solution is as follows:

• For RAM insufficient devices: Enable the Geodata loader optimized for memory-constrained devices by setting the environment variable V2RAY_CONF_GEOLOADER to value memconservative. For more details, see documentation.
• For ROM insufficient devices:
  • Use the newly added GeoIP file geoip-only-cn-private.dat in the zip package or download it from release page, which only contains GeoIP list geoip:cn and geoip:private, or
  • Customize your own GeoIP file via project v2fly/geoip.

v4.41.1

Features

• VMess: Added 2 VMess experiments
  • AuthenticatedLength : Make the length of each payload segment no longer malleable. This experiment requires the server and client use the same version of v2ray-core. More breaking updates on this experiment is expected.
  • NoTerminationSignal : Do not send connection single duplex termination signal for TCP connection when transferred over VMess. This will break some application.
  • #940 Thanks @RPRX
• Hardening Draining connection at client side when receiving invalid data.
  • #940 Thanks @RPRX
• Observatory Support custom probe interval and probe URL. Thanks @nekohasekai .

Fixes

• Fixed connection stability issue when in h2, grpc transport. #1059 #1058 #1056 Thanks @IRN-Kawakaze @architecturers @lijinglin3
• Further fixed connection stability issue when in h2, grpc transport.

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.
