### Added

- TypeScript interfaces. #6, #9
- HMAC feature.
- support for web worker. #14

### Fixed
- 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.

Avioehdolla voit määrätä, että puolet kuolleen puolison omaisuudesta siirtyy verovapaasti leskelle.\n\nVoit halutessasi hyödyntää seuraavia tietoja tekstin muotoilussa persoonallisemmaksi: Käyttäjällä on kumppani nimeltä PARTNER_NAME. Käyttäjällä on suurperhe. Käyttäjällä on lapsiperhe.\n\nPuhuttele käyttäjää siihen sävyyn että tiedät jo mitä käyttäjä haluaa, koska hän on kertonut toiveistaan, ja niiden perusteella tehty suositus on ilmiselvä. Joten älä käytä epävarmoja ilmaisuja kuten "halutessasi", vaan kirjoita itsevarmoilla ilmaisuilla kuten "koska haluat". Älä tee oletuksia käyttäjän sukupuolesta, emme tiedä onko hän mies vai nainen. Älä käytä sanaa jälkikasvu, puhu ennemmin lapsesta tai lapsista riippuen onko lapsia yksi vai useampia. Älä puhuttele käyttäjää ensimmäisessä persoonassa, käytä ennemmin passiivimuotoa. Tekstin sävyn tulisi olla neutraalin asiallinen, ei melodramaattinen eikä leikkisä. Pysy totuudessa, älä keksi uusia seikkoja yllä listattujen lisäksi. Viittaa ihmisiin nimillä silloin kun se on mahdollista. Tekstin tulisi olla vain muutaman lauseen mittainen. Älä siis kirjoita pitkiä selityksiä äläkä kirjoita listoja.
