**FastAPI** は既に多くのアプリケーションやシステムに本番環境で使われています。また、100%のテストカバレッジを維持しています。しかし、活発な開発が続いています。

高頻度で新機能が追加され、定期的にバグが修正され、実装は継続的に改善されています。

これが現在のバージョンがいまだに `0.x.x` な理由であり、それぞれのバージョンは破壊的な変更がなされる可能性があります。これは、<a href="https://semver.org/" class="external-link" target="_blank">セマンティック バージョニング</a>の規則に則っています。

**FastAPI** を使用すると本番用アプリケーションをすぐに作成できますが (すでに何度も経験しているかもしれませんが)、残りのコードが正しく動作するバージョンなのか確認しなければいけません。
