[1.18.0] - 2025-11-24

• IMPROVED: Overall performance/stability (frontend and backend).
• ADDED: TCP Window Manipulation (--tcp-win-mode) - sends fake packets with manipulated TCP window sizes to confuse stateful DPI. Modes: oscillate (cycling window values), zero (zero-window probe attack), random (randomized windows), escalate (gradually increasing windows).
• ADDED: TCP Desync Attack (--tcp-desync-mode) - injects fake TCP control packets (RST/FIN/ACK) with low TTL and corrupted checksums to desynchronize DPI connection tracking. Modes: rst, fin, ack, combo, full.
• ADDED: SNI Mutation for ClientHello fingerprint evasion - modifies TLS handshake structure to bypass DPI fingerprinting. Modes: duplicate (inject fake SNIs), grease (add GREASE extensions), padding (add padding extension), reorder (shuffle extensions), full (all mutations combined), advanced (TLS 1.3 features like PSK/key_share).
