Just a quick heads up that the Ethereum network will experience a planned hard fork at some point early tomorrow. A few of you have emailed me with questions about what you need to do to prepare, and the short answer is that no action is immediately necessary if you’re primarily worried about the continued operation of your miners. Your rigs will continue mining after the fork, and your mining pool will continue payouts to your wallet address (most large pools, including ethermine and nanopool, have already announced readiness for the fork).
You will need to make sure to update your wallet software before creating new transactions (e.g.: sending your ETH to another address) on the Ethereum network post-fork. You don’t need to do this immediately—just make sure that you update before sending coins from your wallet. The latest release of Mist (the official Ethereum client, and the wallet I generally recommend) can be found here. If you use another wallet, make sure that you grab the latest update from your wallet provider.
If you followed my mining guide and installed geth to generate your initial wallet address, there is no need to update it unless you want to use geth to perform manual transactions (which I really don’t recommend!).
