Checkpoint #5: July 2025

Ethereum’s core development continues to accelerate, with the July 2025 Checkpoint highlighting major progress toward the Fusaka upgrade and laying groundwork for the Glamsterdam upgrade. These efforts aim to improve Layer 2 transaction efficiency, data availability, and overall network scalability, while introducing new planning tools and governance processes.

Key Ideas

Fusaka upgrade is targeted for release by end of 2025, focusing on cheaper L2 transactions and enhanced data availability. EIP-7907 was dropped to maintain timeline integrity.
Glamsterdam upgrade planning begins with a new structured process, featuring “headlining features” selection and stakeholder input via the Forkcast tool.
Gas limit increased to 45M and history expiry now defaults to dropping pre-merge history in validators.

Why It Matters?

Developers have the chance to optimize smart contracts for lower gas usage on L2s and prepare applications that leverage increased data availability. Those interested in expanding contract code size should consider championing EIP-7907 for inclusion in Glamsterdam.
