Currently I am running EOS version 1.1.1 for my smart contract, But within a short time so many versions had been released. Before that I was working with 1.0.1 because of some issues I switched to version 1.0.2, Later on I had to upgrade to 1.1.1 within few days.
I know upgradation is a very crucial step in development. But my question is If a beginner want to learn EOS what is the suitable version to start with?
