Error when compiling ValidatorSmartContractAllowList.sol with Solc 0.8.10

[bgravenorst]

I get the following error when compiling the file:

$ solc --optimize --bin-runtime --evm-version=byzantium -o . ./ValidatorSmartContractAllowList.sol

Warning: Visibility for constructor is ignored. If you want the contract to be non-deployable, making it "abstract" is sufficient.
  --> ValidatorSmartContractAllowList.sol:49:5:
   |
49 |     constructor (address[] memory initialAccounts, address[] memory initialValidators) public {
   |     ^ (Relevant source part starts here and spans across multiple lines).

Deleting public appears to work.
