All core dev call has just wrapped up.
Devs have decided to delay the difficulty bomb. Initial block delay adjustment is as published in the proposed EIP-5133 (
https://github.com/ethereum/EIPs/blob/master/EIPS/eip-5133.md) but the delay value may be adjusted. Fork to implement the delay is planned to go in effect around Jun 29.
Also, second testnet for merge will be Sepolia, beacon chain for Sepolia will launch around Jun 20 with merge TTD to follow around 2 weeks after.
