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](https://www.v2fly.org/config/env.html#geodata-%E6%96%87%E4%BB%B6%E5%8A%A0%E8%BD%BD%E5%99%A8).
* 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](https://github.com/v2fly/geoip/releases), which only contains GeoIP list geoip:cn and geoip:private, or
* Customize your own GeoIP file via project [v2fly/geoip](https://github.com/v2fly/geoip).

V2Ray v4.24.2 已发布。
更新内容
* mKCP增加了加密混淆，详情请参考文档。
* VMess 中开始了新协议头的实验，可以更好的防御重放攻击，详情请参考文档。
我们已经知道部分杀毒软件会错误检测V2为病毒，然后暂时交不起让他们别识别V2为病毒的钱。微软的杀毒软件检测V2为"Trojan:Win32/Wacatac.C!ml" , "Program:Win32/Wacapew.C!ml"，我们现在需要每次更新后联系他们让他们把V2从病毒库里面移除。
-----------
V2Ray v4.24.2 has been released.
Update
* VMess's new header format experiment begins. You can now enable VMessAEAD to be better protected. Document
* mKCP can now be encrypted to resist recognition. Document
We are aware some anti-virus software detects V2Ray as malware, which it isn't, but we can't afford to pay the fee needed to make them not detect V2Ray as malware. Microsoft's AV detects V2Ray as "Trojan:Win32/Wacatac.C!ml" , "Program:Win32/Wacapew.C!ml" each time we release a new version, and I have to manually contact them each time to remove it from the malware database.
V2Ray v4.23.4 已发布。
更新内容
* 对 VMess 协议的弱点完成了进一步修复。
* 对 HTTP 头伪装的弱点进行了修复。
-----------
