+## 2024.10.1
+### Note
+- 悪質なユーザからサーバを守る措置の一環として、モデレータ権限を持つユーザの最終アクティブ日時を確認し、 
+7日間活動していない場合は自動的に招待制へと移行（コントロールパネル -> モデレーション -> "誰でも新規登録できるようにする"をオフに変更）するようになりました。  
+詳細な経緯は https://github.com/misskey-dev/misskey/issues/13437 をご確認ください。
+
+### Client
+- Enhance: l10nの更新
+- Fix: メールアドレス不要でCaptchaが有効な場合にアカウント登録完了後自動でのログインに失敗する問題を修正
+
+### Server
+- Feat: モデレータ権限を持つユーザが全員7日間活動しなかった場合は自動的に招待制へと移行するように ( #13437 )
+- Fix: `admin/emoji/update`エンドポイントのidのみ指定した時不正なエラーが発生するバグを修正
+
+### Server
+- Fix: キューのエラーログを簡略化するように  
+  (Cherry-picked from https://activitypub.software/TransFem-org/Sharkey/-/merge_requests/649)
+
 ## 2024.10.0

 ### Note
- サーバー初期設定時に使用する初期パスワードを設定できるようになりました。今後Misskeyサーバーを新たに設置する際には、初回の起動前にコンフィグファイルの`setupPassword`をコメントアウトし、初期パスワードを設定することをおすすめします。（すでに初期設定を完了しているサーバーについては、この変更に伴い対応する必要はありません）  
+- セキュリティ向上のため、サーバー初期設定時に使用する初期パスワードを設定できるようになりました。今後Misskeyサーバーを新たに設置する際には、初回の起動前にコンフィグファイルの`setupPassword`をコメントアウトし、初期パスワードを設定することをおすすめします。（すでに初期設定を完了しているサーバーについては、この変更に伴い対応する必要はありません）  
  - ホスティングサービスを運営している場合は、コンフィグファイルを構築する際に`setupPassword`をランダムな値に設定し、ユーザーに通知するようにシステムを更新することをおすすめします。
  - なお、初期パスワードが設定されていない場合でも初期設定を行うことが可能です（UI上で初期パスワードの入力欄を空欄にすると続行できます）。
 - ユーザーデータを読み込む際の型が一部変更されました。
