On August 3, 2026, Michael D. Thomas, Director of the Information Security Oversight Office (ISOO), signed ISOO Notice 2026-04: Agencies Eligible to Receive Referrals from Automatic Declassification at 25, 50, and 75 Years. This notice provides a comprehensive list of automatic declassification exemptions approved by the Interagency Security Classification Appeals Panel (ISCAP). It rescinds and replaces ISOO Notice 2024-02.
Clear and updated guidelines for automatic declassification referrals are crucial for maintaining transparency while protecting sensitive national security data. Since ISOO Notice 2026-04 rescinds Notice 2024-02, is there a summary document or changelog highlighting the primary updates or added agencies between these two versions?
Please refer to item 12 on the notice that explains the changes between the 2024 notice and the 2026 notice.
