## [4.0.0] - 2022-01-14
### Changed:
- Updated `uuid` package to 8.x.
- In TypeScript, the property `LDEvaluationDetail.reason` is now nullable, which correctly reflects the fact that evaluation reasons may not always be available.
### Removed:
- Removed the type `NonNullableLDEvaluationReason`, which was a side effect of the `LDEvaluationDetail.reason` being incorrectly defined before.
- Removed all types, properties, and functions that were deprecated as of the last 3.x release.
