Is Safe Math needed in standard ERC20 using solidity 0.8 >

Support Contracts

Quick question re SafeMath. I have read that since solidity 0.8 was introduced we no longer need to use Safemath.sol. I just want to be 100% sure that this is definitely the case? I have built a basic custom ERC20. I did notice that some governance tokens have used a newer version of safeMath with contracts deployed using solidity 0.8

For reference here is my ERC20.

pragma solidity ^0.8.0;

import "@openzeppelin/contracts/token/ERC20/ERC20.sol";
import "@openzeppelin/contracts/access/ownable.sol";

contract MyToken is ERC20, Ownable {
    constructor() ERC20("myToken", "My") {
        _mint(msg.sender, 100000000000 * 10 ** 18);
    
    }

    function burn(uint256 amount) external {
        require(owner() == _msgSender(), "Ownable: caller is not the owner");
        _burn(msg.sender, amount);
        
    }
}

The SafeMath library is not needed in Solidity 0.8, because it has overflow checks built in.
