This release focuses on messaging reliability and post-quantum session stability. • Fixed an issue where messages could fail to deliver after deleting and re-adding a contact, or after reinstalling the app. Sessions now recover automatically — no need to log out. • Hardened post-quantum (Kyber) key handling so encryption keys stay consistent across app updates, logins, and device changes. • Improved identity-change recovery: when a contact reinstalls or switches devices, conversations re-establish securely on both the sending and receiving side. • More reliable group chats: correct message timestamps and ordering, plus group push notifications for offline members. • Faster, more dependable chat list updates. • General stability, security, and performance improvements.

What's New: New languages Zero is now available in Spanish, French, German, Portuguese, and Dutch, alongside English. The interface, settings, chats, calls, and the secure vault are translated, and your language is selected automatically based on your device settings. Bug fixes and performance improvements.

This release focuses on reliability around encryption recovery, identity verification, and a cleaner first-launch experience. What's new — Auto-recovery when a contact reinstalls. Your messages now retry against the new session automatically — up to ten recent in-flight messages are resent once the secure channel rebuilds, so you no longer need to send a new message just to restart the conversation. — Identity-change banner. If a contact's encryption identity changes (for example, after a reinstall on their side), Zero now shows a clear banner in the chat. Tap it to compare the old and new safety numbers side-by-side and explicitly accept or reject the change instead of silently trusting the new key. — Cleaner reinstall. Reinstalling Zero now starts you with an empty chat list. New conversations appear as messages come in, the same way Android works. — Friendlier placeholder for messages that can't be decrypted, instead of empty bubbles. Security — Removed a legacy encryption fallback that could expose messages to a key derivable from public information. Every message is now end-to-end encrypted via Signal Protocol with no exception path. — Crypto errors that were previously silent are now logged for diagnosis, so future issues can be tracked down faster. Fixed — An issue causing some users to be logged out unexpectedly during normal app use. As always, no message content, no metadata, no logs, and no telemetry leave your device unencrypted.

What's new in 1.0.7 Group Calls. Encrypted voice and video calls with up to 8 people. Already in a 1:1 call? Add anyone in your contacts and turn it into a group call instantly. Story Indicators. A small red dot appears on a contact's avatar — in your conversation list, contacts list, and on the toolbar plus button — whenever they post a story you haven't seen yet. Modern Composer. The message input has been completely redesigned: a floating glass pill with a morphing send button and tactile spring-press feedback. Custom Chat Backgrounds. Set any photo from your library as the wallpaper for individual chats, with a built-in scrim that keeps text readable. Redesigned Account & License Screens. Floating avatar above the account card, copy-to-clipboard Zero ID, status pill colored by subscription health, and a sleeker license activation screen with one-tap paste. A Cleaner Look. Conversation list cards now match the Settings card style, so the whole app reads with a single, consistent surface. Reliability - VoIP push tokens refresh on every login and unregister on logout, so call notifications work correctly when switching accounts on the same device. - Re-register Encryption Keys performs a full local session reset before uploading, fixing rare decryption failures after long offline periods. - Account deletion now reliably wipes every trace of cryptographic material from our servers. Plus a long list of bug fixes and stability improvements.
