 ## [Unreleased]
 
+## [0.4.0] — 2026-04-24
+
+### Added
+- `src/p2p.rs` — `P2pSender` ve `NodeP2pEvent` (BlockAnnounce, TxGossip); block loop ve RPC handler'larının P2P event'i yayınlamasını sağlar
+- `--p2p-addr` ve `--bootstrap` CLI flag'leri — P2P etkinleştirildiğinde event channel başlatılır
+- `RpcServer::with_p2p` constructor — RPC katmanına P2P gossip sender enjekte eder
+- `nu_sendRawTx`: tx kabul edildiğinde raw bytes P2P gossip channel'ına iletilir
+
 ## [0.3.0] — 2026-04-24
