Ethereum developers have tentatively scheduled the mainnet Fusaka upgrade for December 3, following a key decision at the ACDC 165 meeting. The upgrade timeline includes the Holesky upgrade on October 1, Sepolia on October 14, and Hoodi on October 28. The exact date, time, and epoch number for the mainnet upgrade will be confirmed soon. Initial analysis of Fusaka Devnet-5 suggests that blob capacity will more than double within two weeks of activation. The first BPO fork will increase the target/maximum blob count from 6/9 to 10/15, with a second fork further increasing it to 14/21.
