## AI overview

This July 2025 Ethereum checkpoint covers core developers' work toward the Fusaka upgrade and early discussions about Glamsterdam. Fusaka is intended to deliver cheaper L2 transactions and more data availability, with a target release by the end of 2025. The article explains schedule buffers for security reviews, testnet preparation, and mainnet coordination, and notes that EIP-7907 was removed because it lacked necessary benchmarking.

Ethereum's weekly All Core Developer calls are a lot to keep up with, so this "Checkpoint" series aims for high-level updates roughly every 4-5 weeks, depending on what's happening in core development. See the previous update here. !we-are-here.png...
