 ## 2023.x.x (unreleased)
 
+### Note
+- 絵文字ピッカーにピン留め表示する絵文字設定が「リアクション用」と「絵文字入力用」に分かれました。以前の設定は「リアクション用」として使用されます。  
+
+	**影響：**  
+	それにより、投稿フォームから表示される絵文字ピッカーのピン留め絵文字がリセットされたように感じるかもしれません（新設された投稿用のピン留め絵文字が使われるため）。   
+	投稿用のピン留め絵文字をアップデート前の状態にするには、以下の手順で操作します。
+
+	1. 「設定」メニューに移動し、「絵文字ピッカー」タブを選択します。
+	2. 「ピン留 (全般)」のタブを選択します。
+	3. 「リアクション設定からコピーする」ボタンを押すことで、アップデート前の状態に戻すことができます。
+
