What's New in Addendum.

• Change your passphrase without typing the old one. Where your device can confirm it's you (Face ID, Touch ID or your Mac login), it steps in instead. • Extra protection to match: if the passphrase is changed without that proof, the few settings that could lock you out stay on hold until you confirm with Face ID, Touch ID or your recovery key. • Updated 2027-cycle guidance in Apply → Guidance for CVs, letters, signaling and DO applicants. • Bug reports you choose to send reach us again. • The app now names both things that can ever leave your device: optional iCloud sync, and a bug report you write and send. • Fixes: two open windows can no longer overwrite each other, a refused save now says what actually happened, printing works on the Mac, and the de-identification check also reads field names and numbers.
