I was checking some pretty old contract samples of OpenZeppelin v2.5, and they are in Solidity 0.5.0, and I am not sure if it is a safe version, or not.
If I extend these types of contracts, it makes me use Solidity 0.5.0 in my contracts, when we are in Solidity >0.8.
Should I keep my Solidity version updated to the 0.8, and only use compatible contracts, or should I forget about the Solidity versions?
Thanks everybody
