Now we are on 0.14.x software, what would happen if someone opens a 0.11.x, 0.12.x or 0.13.x GUI/CLI?

Also, when Monero forks again later in 2019, what will the 0.14.x GUI/CLI present to the user?

When starting the daemon, monerod, or one of the command line wallets (monero-wallet-cli, monero-wallet-rpc), if you are running an old version, it prints a warning message telling you an update is needed. It's worth noting that it does this by checking your blockchain height against the hard-coded fork heights, not by calling some remote update server.

I'm not as familiar with the GUI, but presumably it warns you also.

  • So if you're using the CLI and haven't updated you get a warning, but you continue to download blocks from the old chain? If this is right, I think I read somewhere that when you update your software, it pops-blocks (deletes) back to a block height before the fork. Then when block height catches up to the forking block height, it starts downloading blocks from the latest chain. Is this correct? Mar 16, 2019 at 12:48
  • No, if you're on the wrong chain, you'll need to manually pop blocks.

  • Thanks. I'll explore what the GUI does unless someone else pipes up. Mar 19, 2019 at 10:58
