Update完了

公式サイトを確認すると、

11.3.10ではsymfonyのセキュリティ修正版である

• 該当するパッケージであるsymfony/http-foundation他を7.4.12
• 該当するパッケージであるtwigを3.26.0

にアップデートを行い

11.3.11ではsymfonyのセキュリティ修正版である

• 該当するパッケージであるsymfony/http-foundation、symfony/routingを7.4.13
• 該当するパッケージであるsymfony/polyfill-intl-idnを1.38.1
• 該当するパッケージであるtwigを3.27.0

にアップデートしています。

このパッケージの修正に関わるsymfonyのアドバイザリーのメッセージが表示されていたので、通常のアップデートと異なるメッセージが表示されました。

今回、見慣れないメッセージが表示されたので、久しぶりに、公式サイトのアップデート内容とその元になるsymfonyのアップデートを確認しました。

本来は、常に確認すべきですが、アップデート通知が来て、--dry-runで問題なければアップデート実行という形で問題なかったので、しばらくアップデートの詳細を公式サイトで確認していなかったのは反省すべきと考えています。今後はアップデート通知やセキュリティ通知が来たら公式サイトで内容をしっかり確認したいと考える出来事でした。
