Attention Needed

XQUIC now works with other QUIC softwares on stateless reset, but if both XQUIC client and server are used in your system, it is adviced that compile XQUIC with -DXQC_COMPAT_GENERATE_SR_PKT=1. With this macro, XQUIC server will generate the Stateless Reset Token as the original method to compat with the client with older versions of XQUIC, while XQUIC client will try to parse a packet as an original stateless reset packet after failed to decrypt or find a connection with the stateless reset token parsed from the packet as a standard stateless reset packet.
