      New Features

      Peer-to-Peer Synchronization

      Using Couchbase Lite’s Peer-to-Peer Synchronization solution, you can build offline-first applications on edge devices that directly collaborate in secure bi-directional database synchronization without depending on centralized cloud-based control.

      The solution provides an out-of-the-box implementation of a websocket based listener for use in peer-to-peer applications communicating over in IP-based networks.

      • CBL-954 — Return 403 for forbidden listener requests

      API Changes

      The API has been enhanced with the following changes:

      • The Database.close() method now automatically handles stopping open replicators, closing peer-to-peer websocket listener and removing observers for live queries.

      • The Database.delete() method now automatically handles stopping open replicators, closing peer-to-peer websocket listener and removing observers for live queries.

      • The Replicator.isDocumentPending() method checks whether or not the document with the given ID has any pending revisions to push

      • The Replicator.pendingDocumentIds() method gets the Ids of all documents currently pending push

      • Meta.revisionID property is now available as a metadata property, which can be accessed directly in queries

      Issues and Resolutions

      Known Issues

      • CBL-1403 — Compiling an app archive for distribution with the Rebuild from Bitcode option enabled will result in compiler errors. Disable bitcode to allow your compilation to proceed
