+- deprecated `new Buffer`, replace with `Buffer.from`. #10
+- dependencies and security issues.
+- refactor: simplify formatMessage internal logic.
+- Generates incorrect hash in some cases.
+
+### Changed
+- remove `eval` and use `require` directly. #8
+- throw error by Error oject.
+- throw error if update after finalize
+- use unsigned right shift.
