I am a user what have i to do?

if you are a holder and you keep funds into third parties wallet (for example exchangers as Kraken, Coinbase, etc) or into Metamask or Myetherwallet or hardware wallets as Ledger nano S, etc you will have nothing particular to do. You should not worry in any way. If your provider will push some changes it will advise you on any additional steps. On web wallets or exchangers, for example, they will take care of software fixes. In case of hardware wallet, it may be possible that the supplier will decide a software upgrade on the wallet itself. in that case the notice will be provided as connecting to the device next time after the upgrade.

i am an operator or miner

in this case you shall download the latest version of your Ethereum client and install them on your system. Consider the following:

  • Latest geth client (v1.8.23)
  • Latest Parity client (v2.2.10-stable)
  • Latest Harmony client (v2.3 Build 74)
  • Latest Pantheon client (v0.9.1)
  • Latest EthereumJS VM client (v2.6.0)
  • Latest version of Nethermind client (v0.9.4)
  • Latest version of Ethereum Wallet/Mist (v0.11.1)

if you are miner or operator and dont upgrade the software you will not be able to run new transactions on the network after the upgrade. So stay tuned.
