Remember: if you are a GPU miner (not a mobile miner!) you'll need to ensure you update your mining software - even if you mine to a pool.
For instance:
https://github.com/nanopool/Claymore-XMR-Miner/releases
Claymore miner will need the flag -pow7 1
to use the new algorithm and get you mining Electroneum again.
https://github.com/fireice-uk/xmr-stak/releases
XMR Stak, you need to update the “currency” option in the config file "pools.txt" to "cryptonight_v7". Do NOT use "electroneum" as this won’t work.
Check your pool or your pool's social media channels. They will probably have provided details.
