Ethereum puts compatibility under the spotlight

Why the upgrade process paused

An Ethereum Foundation post dated November 6 says testing of the proposed Glamsterdam changes revealed compatibility concerns involving EIP-8037 and EIP-8038. The changes affect gas accounting and state costs. The post says the hard-fork process and Hoodi activation were delayed while the issues are examined; work on Hegota continues separately.

The latest published update

The November 9 update says four reports had identified deployed contracts that might break under the proposed changes. It lists audit reporting on November 13, a findings discussion on November 16 and a further discussion on November 19. These are scheduled steps, not completed events. No decision on the next steps was pre-committed in that update. ChainSecurity’s technical write-up provides further detail on the gas-behavior concerns.

Our perspective

This is a compatibility story, not proof that a mainnet upgrade has already happened or that all contracts are affected. The useful distinction is between a proposal, a test result and an activated network change. Readers following the roadmap should look for the published audit findings and explicit updated activation instructions, rather than treating an older roadmap date as final.
