## v0.8.0 / 2023-09-27
### Added - TypeScript interfaces. - HMAC feature. ### Fixed - deprecated `new Buffer`, replace with `Buffer.from`. - dependencies and security issues. - don't modify global Array and ArrayBuffer prototypes. - refactor: simplify formatMessage internal logic. ### Changed - remove `eval` and use `require` directly. - throw error by Error oject. - throw error if update after finalize - use unsigned right shift.
