### [](#new-features)New Features

#### [](#multipeer-replicator)Multipeer Replicator

Couchbase Lite 3.3.0 introduces the new Multipeer Replicator API for bidirectional peer-to-peer synchronization in both Swift and Kotlin platforms. This replicator enables secure, direct synchronization between devices without the need for a centralized Sync Gateway.

The Multipeer Replicator supports:

* Peer discovery using DNS-SD (Bonjour) over a shared Wi-Fi network
* Encrypted TLS connections with certificate-based authentication
* Automatic mesh formation and replication routing between peers
* Real-time updates using continuous, push-and-pull replication

Each device advertises itself using a shared group ID, discovers others, and forms an optimized mesh network for efficient data sync. Multipeer Replicator performs authentication using client/server certificates, and applications can configure custom filters, conflict resolvers, and listeners for fine-grained control.

For more information about Multipeer Replicator, see:

* [Swift Multipeer Replicator](swift/p2psync-multipeer.md)
* [Android Multipeer Replicator](android/p2psync-multipeer.md)

> [!NOTE]
> This feature supports only continuous, push-and-pull replication. Version 3.3.0 disables Delta Sync by default.
