 ## 2026.6.1
 
+### Note
+
 **今回のリリースではMisskeyの各種動作要件が変更されます。必ずアップグレード前にお使いの環境をご確認ください。**
 
-### Note
 - センシティブメディアの判定 (NSFW検出) が、本体に内蔵された nsfwjs による推論から、外部サービス [sensitive-detector](https://github.com/misskey-dev/sensitive-detector) への HTTP 呼び出し方式に変更されました。
 	- これに伴い、本体から `nsfwjs` / `@tensorflow/tfjs` / `@tensorflow/tfjs-node` および同梱の NSFW 判定モデルが削除され、インストール要件 (ネイティブ ML スタック) が緩和されました。
 	- **センシティブ判定機能を利用しているサーバーは対応が必要です。** 別途 [sensitive-detector](https://github.com/misskey-dev/sensitive-detector) サービスを立ち上げ、コントロールパネルの「モデレーション > センシティブなメディアの検出」で接続先 URL を設定してください。接続先が未設定の場合、センシティブ判定は行われません (すべて非センシティブ扱い)。
 	- 画像の正規化・動画フレームの抽出・しきい値判定・集約は引き続き本体側で行われ、外部サービスには正規化済み画像の推論のみを委譲します。
-- バックエンドで画像処理に用いているライブラリ sharp のシステム要件の変更により、**SSE4.2 命令セットをサポートしていない CPU では Misskey が正しく動作しなくなります**。仮想マシンに Misskey をデプロイしている場合や、古いハードウェアをお使いの場合は、アップデート前にお使いの環境をご確認ください。
-- Node.jsの最低サポートバージョンを 22.22.2 に引き上げました。これより古いバージョンの Node.js では Misskey が起動しません。
+- Node.js v24, v26 をサポートしました。**Node.js v22 でも動作しますが、今後のリリースで v22 のサポートを終了する予定**ですので、Node.js のアップデートをご検討ください。
+  - Node.js のセキュリティアップデートに伴い、最低動作バージョンを 22.22.2 / 24.17.0 / 26.4.0 に引き上げました。
+  - Docker Image は Node.js 26.4.0-trixie に更新されています。
+- バックエンドで画像処理に用いているライブラリ sharp のシステム要件の変更により、**SSE4.2 命令セットをサポートしていない x86_64 CPU では Misskey が正しく動作しなくなります**。仮想マシンに Misskey をデプロイしている場合や、古いハードウェアをお使いの場合は、アップデート前にお使いの環境をご確認ください。なお、ARM64 など x86_64 ではない環境においてはこの変更による影響はありません。
 
 ### General
 - Feat: コントロールパネルから二要素認証を解除できるように
 
 ### Client
+- Fix: チャットでIMEの変換を確定するEnterでメッセージが送信されてしまうことがある問題を修正
 - 2025.4.0 以前の設定情報の移行処理が削除されました
 	- 2025.4.0 から直接 2026.6.0 以上にアップデートする場合は設定が移行されませんので注意してください。移行したい場合は一度 2026.5.1 を経由してください。
+- Fix: デバイスタイプをスマートフォンに固定している状態で画面幅が広いとき、画面左上のアイコンが表示されない問題を修正
 
 ### Server
 - Enhance: センシティブメディアの判定を外部サービス ([sensitive-detector](https://github.com/misskey-dev/sensitive-detector)) に分離し、`nsfwjs` / `@tensorflow/tfjs(-node)` の同梱と NSFW 判定モデルを廃止 (#16804)
-
+- Enhance: Node.js 22.23.0以降、24.17.0以降、26.4.0以降をサポートするように
+- Enhance: Docker Image の Node.js を 26.4.0 に、Debian を trixie (v13) に更新
+- Fix: `/stats` API のレスポンス型が正しくない問題を修正
+- Fix: ハッシュタグに関連するデータを更新する際のエラーハンドリングを修正

+### 命名規則
+
+本来それが略称であっても、通常それでひとつのワードとして用いられるものは、略称として扱わない。
+
+#### 例: IP address
+
+Good: `ipAddress` / `IpAddress`
+
+Bad: `IPAddress`
+
+#### 例: User ID
+
+Good: `userId` / `UserId`
+
+Bad: `userID` / `UserID`
+
+#### 例: XMLなHTTPのRequest
+
+Good: `xmlHttpRequest` / `XmlHttpRequest`
+
+Bad: `XMLHttpRequest` / `XMLHTTPRequest`
+
+### 関数化の基準
+
+汎用性が低く(例えばそれを関数化したとしてもその呼び出しが元の場所一か所しか存在しない)、内容も短い処理(例えば10行以下)は、かえって読みにくくなるため、関数化しない。
+
+また、関数化する場合でも、呼び出しがある特定のスコープに限られる場合は、そのスコープ内に閉じ込めた方が分かりやすく簡潔になる場合がある(ただし本来その処理に不要であっても、構造上親のスコープにある関係のない変数や引数にもアクセスできるようになるため、必ずしもそうすれば設計上綺麗になるというわけでもない。状況に応じて判断すべし)。
+
+Bad:
+
+``` ts
+function withBrankets(x) {
+	return `(${x})`;
+}
+
+function formatPercent(x) {
+	return `${x}%`;
+}
+
+function formatValue(x) {

+}
+
+function showData(a, b) {
+	console.log(formatValue(a));
+	console.log(formatValue(b));

+function formatValue(x) {
+	return `(${x}%)`;
+}
+
+function showData(a, b) {
