     - この Firefish はよく Firefish neko flavor と呼ばれていますが、これはこのバージョン番号に由来します。私自身は特にこの呼称を普及させたいわけではなかったのですが、[私のアカウント](https://post.naskya.net/@dev)の数割のフォロワーが英語圏の本家 Firefish の利用者であるため単に「この機能を追加しました！」などと投稿すると本家版の更新と誤解される恐れがありますし、「私の Firefish フォークにこの機能を追加しました！」などと投稿すると私が本家 Firefish の開発を離れて新たなハードフォークを作っているのだと誤解される恐れがあるため、投稿を機械翻訳で英訳されて読まれてもなるべく誤解されないための苦肉の策としてこの呼称を使い始めました。このソフトフォークはあくまで本家 Firefish の私による「味付け」です。
 - 依存ライブラリをほとんど常に最新版にアップデート
   - 本家版を更新する前にちゃんと動くか実験したいという意図もあります
-- `native-utils/migration` を廃止
+- Rust によるデータベースのマイグレーションを廃止
   - Rust に移植できる部分は少しずつ移植していきますが、Rust によるデータベースのマイグレーションは（少なくとも当面の間）行いません
