For anyone upgrading from v9, please be aware there are a LOT of config changes.

To make your lives easier, we wrote a tool to help you...

https://gunbot.tools

Simply paste in your current v9 config, this tool will validate it and tell you everything that is wrong.  (This happens purely client side)
We can also fix it for you, in which case your config (minus its keys, smtp user/pass, withdraw address, telegram token, and other sensitive data) is sent to our server to be upgraded.
