この更新の概要
Claude CodeのZero Data Retention（ZDR）機能の適用条件が更新され、特定の要件を満たした「qualified accounts」のみが対象であることが明示されました。ZDRは標準のエンタープライズプランには含まれず、管理画面からの設定もできないため、個別にAnthropicの営業チームへの問い合わせが必要である旨が追記されています。データ保持に関する制限事項や、有効化のための具体的な手続きについての説明が強化されました。
ZDR機能の利用対象が、Claude for Enterpriseを利用する「qualified accounts（適格なアカウント）」に限定されるよう記述が修正されました。
