The Ethereum Foundation announced the Platåberget testnet, an early public testing ground for the Glamsterdam upgrade (combining 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. Platåberget is open for public participation ahead of mainnet, and the Ethereal news weekly #36 newsletter additionally flagged the Glamsterdam upgrade as a headline item for the ecosystem.

• Platåberget testnet validates the Glamsterdam changes across consensus client teams (PandaOps).
• Developers relying on hardcoded gas cap limits must update their tooling.
