Labyrinth 1.1: Making End-to-End Encrypted Backups Even More Reliable

Labyrinth 1.1 improves the reliability of end-to-end encrypted backups in Messenger by allowing messages to reach the encrypted backup in real-time, rather than waiting for the device to come back online. This is achieved through a new sub-protocol that ensures messages survive device loss, changes, and extended sign-in gaps. The update enhances the security and integrity of encrypted message history, making it more accessible to users across devices.
