Legacy XTLS protocols (
xtls-rprx-origin,xtls-rprx-directandxtls-rprx-splice) have been marked as deprecated and got removed in Xray-core v1.8.0+ few months earlier. We are also planning to remove this because the old XTLS protocols are based on a fork of Gocrypto/tlsstandard library, which causes the duplicated compilation of TLS code and about 0.2MB of binary size and runtime memory.Considering that there are still people using these deprecated protocols, we plan to delay merging this change, but would not later than the Go 1.21 release.
If you are a user of legacy XTLS protocols,
Please update your proxy server program as soon as possible and then switch to
xtls-rprx-visionflow.xtls-rprx-visionis the newer version of XTLS protocol family, which has fixed some flow characteristics in its design. Note that legacy XTLS protocols are not compatible with XTLS Vision, you should update both client and server to use that flow.
