[1.21.1] - 2025-12-07

  • ADDED: TCP SYN Fake TTL slider option.
  • FIXED: SYN fake packets sent with full TTL when using non-TTL faking strategies (randseq/pastseq), causing fake packets to reach servers and break handshakes.
  • FIXED: Config validation incorrectly comparing set ConnBytesLimit against stale MainSet defaults instead of loaded JSON values.
  • FIXED: UI bug when ui crashes on creating a set with Overlap fragmentation option.
