Summary

Reduce gas usage by moving to Solidity 0.8.19 or later

Vulnerability Details

In earlier releases and in the default legacy code generation, when an internal library function or a free function accessed via a module was called only during contract creation, e.g. only in the constructor, a copy of the function still also occurred in the contract's runtime bytecode. This was fixed in the version 0.8.19 and later.
