# Objective - Remove `derive_more`'s error derivation and replace it with `thiserror` ## Solution - Added `derive_more`'s `error` feature to `deny.toml` to prevent it sneaking back in. - Reverted to `thiserror` error derivation ## Notes Merge conflicts were too numerous to revert the individual changes, so this reversion was done manually. Please scrutinise carefully during review.
