# WorkSpaces アプリケーションエージェントのリリースノート
<a name="agent-software-versions"></a>

Amazon WorkSpaces Applications エージェントソフトウェアはストリーミングインスタンスで実行され、エンドユーザーはストリーミングアプリケーションに接続して開始できます。2017 年 12 月 7 日以降、ストリーミングインスタンスは、利用可能な最新の機能、パフォーマンスの向上、およびセキュリティ更新プログラムで自動的に更新できます AWS。2017 年 12 月 7 日より前は、新しいベースイメージリリースにエージェントの更新プログラムが含まれていました。

最新の WorkSpaces Applications エージェントソフトウェアを使用するには、2017 年 12 月 7 日以降 AWS に によって公開された新しいベースイメージを使用してイメージを再構築する必要があります。この操作を行う場合、エージェントの自動更新を有効にするオプションが Image Assistant でデフォルトで選択されます。このオプションを選択したままにし、新しい Image Builder またはイメージから起動される新しいフリートインスタンスで、常に最新バージョンのエージェントが表示されるようにすることをお勧めします。詳細については、「[チュートリアル: WorkSpaces アプリケーションコンソールを使用してカスタム WorkSpaces アプリケーションイメージを作成する](tutorial-image-builder.md)」を参照してください。

次の表は、Windows インスタンス用の WorkSpaces アプリケーションエージェントのリリースバージョンで利用可能な最新の更新を示しています。
