Developer Guidelines

Changes to the UpsetConfig type require writing config conversion functions to ensure backwards compatibility. See the note at the top of packages/core/src/convertConfig.ts for details. Additionally, the typechecker for the UpsetConfig must be updated when the type is. See packages/core/src/typecheck.ts. Additionally, all the types used within UpsetConfig have their own typecheck functions; changes to these types must be reflected in the typechecker.
