SHA2 miners should stop mining Saturday.\n\n- nostr:nprofile1qqsg3mj8tuxhxvy5w0qt9altpgcrqttdfxg9glvsdfhkpa3plcxfudgpzpmhxue69uhkummnw3ezumt0d5hszrnhwden5te0dehhxtnvdakz7qgawaehxw309ahx7um5wghxy6t5vdhkjmn9wgh8xmmrd9skctckum9s8 29.4.1rc4 will be released tomorrow, setup for mainnet rehearsal. This locks-in the final SHA2 block.\n- After NYPost updates their Sunday morning print online, I'll post the canonical blake2b_headline parameter.\n- If things go perfectly, Knots 29.4.1 final will be released Sep 1 on schedule, keeping the Aug 30 blockchain.\n- If there's any issues (unlikely at this point), we address them and reset to the last SHA2 block for rc5.\n\nIf you intend to mine from day 1, I recommend getting setup with testnet4 (rc3) _now_ so you're ready for mainnet on Sunday."}
