Nethermind 1.39.0 is live: 337 changes since 1.38.1. 𝗥𝗲𝘀𝘁𝗮𝗿𝘁 𝘀𝗮𝗳𝗲𝘁𝘆: Header sync now recovers after a lost chain level on unclean shutdown, and Flat DB writes are durable across restarts, closing a real gap where nodes could come back up corrupted after a bad shutdown. 𝗥𝗼𝗮𝗱 𝘁𝗼 𝗚𝗹𝗮𝗺𝘀𝘁𝗲𝗿𝗱𝗮𝗺: EIP-7928 (Block-level Access Lists) reaches devnet-7 support with a real performance pass, cutting allocations on the BAL generate and validate paths. eth/71 ships alongside it, the wire protocol that lets peers exchange BALs directly. EIP-8037 rounds it out, metering gas for state growth. 𝗝𝗦𝗢𝗡-𝗥𝗣𝗖: Eight new methods, including eth_sendRawTransactionSync, eth_baseFee, and eth_capabilities, plus streaming responses for debug_ and trace_ calls and a correctness pass across eth_estimateGas, eth_simulateV1, and eth_createAccessList. 𝗙𝗶𝘃𝗲 𝗯𝗿𝗲𝗮𝗸𝗶𝗻𝗴 𝗰𝗵𝗮𝗻𝗴𝗲𝘀 𝘁𝗵𝗶𝘀 𝗿𝗲𝗹𝗲𝗮𝘀𝗲: - Legacy BloomStorage removed - Discovery defaults to V4 - Per-method JSON-RPC metrics on by default - Non-spec error field dropped from receipts - IPC sockets restricted to owner-only(Nethermind)
