Ethereum Foundation just announced Glamsterdam upgrade going live on Sepolia testnet October 6th

Key upgrades:
• ePBS - moves block building into protocol layer (huge for MEV)
• Block-Level Access Lists - faster node processing
• New gas structure overhaul

Mainnet date TBA but this is the pre-game. Watch $ETH narrative shift as ePBS rolls out - changes the entire MEV game and validator economics

Sepolia first, then we see if this actually delivers on the efficiency promises
