 # B4 - Bye Bye Big Bro
 
-## [1.61.0] - 2026-05-09
+## [1.61.1] - 2026-05-09
 
 - ADDED: **Custom payload for UDP fake packets** - new "Fake Packet Payload" picker in the UDP fake settings of each set. Choose a captured `.bin` (uploaded in Settings → Payloads, or auto-captured from live QUIC traffic) to use as the body of fake UDP packets. Empty = zero fill (previous behavior). The Settings → Payloads upload form now has an explicit TLS/QUIC protocol selector.
 - ADDED: **Auto-generated QUIC Initial payload** - new "(auto: QUIC Initial)" option in the UDP Fake Packet Payload picker. b4 generates a fresh randomized QUIC Initial packet for every fake, with random connection IDs each time, so no upload is needed and the bytes can't be fingerprinted by repetition. Recommended packet size for this mode is 1200 bytes. Works with any Faking Strategy (None / TTL / Checksum).
