Ethereum client Prysm: System issue identified and temporary solution provided

ChainCatcher reported that the Ethereum client Prysm has identified the issue and provided a quick temporary solution. All nodes should disable the unnecessary generation of old states in Prysm to handle expired attestations. Simply add the flag “--disable-last-epoch-targets” to the beacon node. This parameter applies to version v7.0, so there is no need to further upgrade the beacon node; just add this parameter. No changes are required for the validator client.
