Preface: My iPhone 15 pushed the iOS 26.4.2 update again on May 2, 2026. I think even if you installed it around April 24—is likely because Apple released a revised build of that same update to address continued issues, or my device failed to properly register the previous installation due to the emergency nature of the patch.

Background: Why I received the update again on 1st May 2026. The NVD’s last modified date is shown as April 29, 2026. Therefore, this is one of the reasons why I need to perform the analysis again. Why update again? Similar to previous scenarios in 2023, Apple often re-issues critical patches if the first version did not fully resolve the issue, was causing compatibility problems, or if new information about the vulnerability arose.

My observation: The April 29 update reinforces why your switch to PRAGMA secure_delete = ON; is the right move. The official fix description—”improved data redaction”—aligns with the behavior of secure_delete, which physically overwrites data to ensure it cannot be recovered via forensic tools.

By using the PRAGMA, you are implementing at the application level what Apple has now implemented at the OS level: ensuring that when a record is “deleted,” its physical remnants are immediately destroyed.
