Ethereum Clients Now Support Pruning of Pre-Merge Historical Data

According to PANews, the Ethereum Foundation's official blog announced that all Ethereum execution clients now support pruning of pre-merge historical data. This update will reduce the disk space required for nodes running on the mainnet by 300-500 GB. The upgrade does not affect the normal operation of full nodes and validators, but it does offer storage space savings. Users of archive nodes and application developers who need access to complete historical data will need to gradually transition to external historical data providers. Relevant resources can be found at https://eth-clients.github.io/history-endpoints/. This initiative marks the first step in Ethereum's implementation of the 'historical data expiration' mechanism defined in EIP-4444, aimed at optimizing network storage efficiency. More details can be found in the related EIP documentation.
