Fixed notification duplicates after the encryption upgrade. UI improvements.

Encryption upgrade We’ve upgraded Cord’s end-to-end encryption. Your existing cords stay the same — no need to recreate them Messaging continues once everyone in a cord has updated Messages sent while someone was still on an older version may not decrypt If you previously verified contacts, compare safety numbers again Privacy unchanged: no phone number, email, or contact upload required.

• Stronger cord invites — new cords use a secure invite (QR or share link). The Cord ID alone is no longer enough to join • Share invite from an empty chat works reliably on iPhone and iPad • Clearer guidance when creating and joining cords

React to messages with emoji Mute notifications for a cord (1h, 8h, or until you unmute) Follow your device’s light/dark appearance, or lock Light or Dark

Fixed issue with delay on first chat in new cords and an issue with viewing files in chat.

Minor fixes to chat and UI

Stability and speed improvements

UI/UX • General improvements across the app. Security & privacy • Stronger encryption: improved forward secrecy for new sessions and ongoing key rotation. • Display names and profile photos in a cord are now encrypted with a per-cord key—servers only store ciphertext. • Verify a contact’s safety number from a participant’s profile to check for impersonation. • Reduced metadata on our servers (including more private routing identifiers).

• Stronger privacy: cord and member details are now restricted to cord members only. • More secure joining: passphrases are verified safely on the server and never exposed. • Smoother QR scanning and a fix for the missing back button after joining. • Reliability improvements to joining cords. Your messages remain end-to-end encrypted. Please update to keep joins working smoothly.

Improved group chat functionality Improved tablet compatibility Minor UI improvements Enjoy!

This update improves navigation and removes a few confusing edge cases to make Cord feel smoother in daily use. * Added swipe-back navigation support (edge swipe from left to right) where available, while keeping the back button. * Improved Cord creation flow so the same Cord ID is shown and used throughout creation. * Updated onboarding copy to reflect that Cord is now live in production. * Added clear/remove options for aliases, so you can easily remove an alias when needed. * General UI polish and reliability improvements. * Android 16 KB page-size compatibility improvements.
