 ## 2025.3.2
 
 ### General
--
+- Feat: チャットがリニューアルして復活しました
+  - 既存のDM機能よりも便利で効率的になっています
+  - チャットを受け付ける相手を制限できます
+	- チャット機能を開放するかどうかをロールで制御できます
+- Enhance: セキュリティを強化するため、ジョブキューのダッシュボード(bull-board)統合が削除されました。
+  - Misskeyネイティブでダッシュボードを実装予定です
 
 ### Client
 - Feat: 設定の管理が強化されました
-  - 自動でバックアップされるように
+  - 内部処理が一新され、安定性とパフォーマンスが向上しました
+  - 全てのクライアント設定がエクスポート(バックアップ)/インポート対象に含まれるようになりました
+    - プラグイン、テーマ、クライアントに追加されたすべてのアカウント情報も含まれるようになりました
+  - 自動で設定データをサーバーにバックアップできるように
+    - 設定→設定のプロファイル→自動バックアップ で有効にできます
+    - 新しいデバイスからログインしたり、ブラウザから設定データが消えてしまったときに自動で復元されます(復元をスキップすることも可能)
   - 任意の設定項目をデバイス間で同期できるように
+    - 設定項目の「...」メニュー→「デバイス間で同期」
+    - 同期をオンにした際にサーバーに保存された値とローカルの値が競合する場合はどちらを優先するか選択できます
+  - 任意の設定項目を初期値にリセットできるように
+    - 設定項目の「...」メニュー→「初期値にリセット」
+  - アカウントごとに設定値が分離される設定とそうでないクライアント設定が混在していた(かつ分離するかどうかを設定不可だった)のを、基本的に一律でクライアント全体に適用されるようにし、個別でアカウントごとに異なる設定を行えるように
+    - 設定項目の「...」メニュー→「アカウントで上書き」をオンにすることで、設定値をそのアカウントでだけ適用するようにできます
+  - ログアウトすると設定データもブラウザから消去されるようになりプライバシーが向上しました
+    - 再度ログインすればサーバーのバックアップから設定データを復元可能です
+  - エクスポートした設定データを他のサーバーでインポートして適用すること(設定の持ち運び)が可能になりました
+- Feat: 画面を重ねて表示するオプションを実装(実験的)
+	- 設定 → その他 → 実験的機能 → Enable stacking router view
 - Enhance: プラグインの管理が強化されました
   - インストール/アンインストール/設定の変更時にリロード不要になりました
 - Enhance: ログアウト時、ブラウザに保存されたWebクライアントのデータを全て消去するように
 - Enhance: CWの注釈テキストが入力されていない場合, Postボタンを非アクティブに
 - Enhance: CWを無効にした場合, 注釈テキストが最大入力文字数を超えていても投稿できるように
 - Enhance: テーマ設定画面のデザインを改善
+- Enhance: 投稿フォームの設定メニューを改良
+  - 投稿フォームをリセットできるように
+  - 文字数カウントを復活
+- Enhance: 2段階認証時のリカバリーコードのファイル名にサーバーURLを含めるように
 - Fix: テーマ切り替え時に一部の色が変わらない問題を修正
 
 ### Server
+- Enhance 全体的なパフォーマンス向上
 - Fix: プロフィール追加情報で無効なURLに入力された場合に照会エラーを出るのを修正
 - Fix: ActivityPubリクエストURLチェック実装は仕様に従っていないのを修正
+- Fix: 連合無しモードでも外部から照会可能だった問題を修正
+- Fix: テスト用WebHookのペイロードの`emojis`パラメータが実際のものと異なる問題を修正
