Changelog
What shipped, and when. Version numbers and dates are pulled from the App Store listing, so this page cannot quietly disagree with what Apple shows.
1.0
- First App Store release.
- End-to-end encrypted one-to-one messaging using X3DH and the Double Ratchet with AES-256-GCM.
- Post-quantum handshake on iOS 26: X-Wing, combining ML-KEM-768 with X25519.
- Accounts are BIP-39 recovery phrases generated on device - no phone number, no email.
- Stealth addressing: a fresh one-time address per message.
- Fixed padding buckets at 32, 64, 128, 256 and 512 bytes.
- Optional cover traffic at random 3-10 minute intervals, off by default.
- Anonymous payment via RSA blind signatures, so a send cannot be linked to a purchase.
One release so far. This page exists at version one rather than appearing later, because a changelog that starts when the history is already flattering is not much of a record. Security fixes will appear here and on the security page as they ship.
