Bitcoin Core v31.0 discloses privacy bug: -privatebroadcast feature can expose node IP addresses

Bitcoin Core developers disclosed on June 6 that the optional -privatebroadcast feature in v31.0 — designed to route transactions privately via Tor — can reveal the originating node's IP address due to a BIP324 v2 handshake failure.
