Ethereum Holešky testnet to shut down soon

The Holešky testnet has reached end-of-life. Two weeks after the Fusaka upgrade is complete, most validators will be shut down. It will no longer receive support from the client, test, and infrastructure teams. Existing Holešky users should migrate to the new testnet, Hoodi, while application and tool developers are encouraged to use Sepolia. Following the closure of Holešky, the Ethereum testnet ecosystem will consist of Sepolia, Hoodi, and Ephemery.
