Ethereum Foundation launches Platåberget testnet for Glamsterdam upgrade

The Ethereum Foundation opened the Platåberget testnet, an early public testing ground for the Glamsterdam upgrade — the combination of the Gloas and Amsterdam upgrades. The upgrade introduces breaking changes for application developers: any tool that relies on a hardcapped maximum gas limit — such as wallets, indexers, and gas estimators — will break and must be updated.

The testnet is validating the Glamsterdam changes across consensus client teams including PandaOps, and is open for public participation ahead of mainnet. Notably, Glamsterdam's repricing means gas pricing will no longer be capped at a fixed hardcoded maximum, so developers should update any tooling that assumes a maximum gas limit.
