      3.1.0 — March 2023

      Version 3.1.0 for C delivers the following features and enhancements:

      Scopes and Collections

      Couchbase Mobile’s cloud-to-edge support for scopes and collections allows application developers to organize and logically isolate data.

      Independent lifecycle management and fine-grained security control simplifies the deployment of multi-tenant and high-application density cloud-to-edge applications at scale.

      Scopes and Collections are a first class concept, synced between Couchbase Lite and Sync Gateway, between Sync Gateways (Inter Sync Gateway Replication), between Couchbase Lite peers, as well as available offline-first on Couchbase Lite devices.

      3.0.0 — February 2022

      On upgrading from a 2.x release, all Couchbase Lite databases will be automatically re-indexed on initial database open.
      This can result in a delay before the database is usable.

      New Features

      Couchbase Lite for C

      Couchbase Lite now has an officially supported C API, which builds on the success of the well-received engineering labs C API for Couchbase Lite.

      The C API now includes support for Enterprise-grade features like database encryption. This optimized implementation is ensured feature parity with our other Couchbase Lite platforms and is supported on a wide-range of mobile and desktop platforms — see: Supported Platforms.

      The ease of building language bindings on top of the C API means application developers can build for edge and embedded IoT devices using their preferred languages to harness the power of Couchbase Lite.

      SQL++/N1QL Query Strings

      Couchbase Lite’s SQL++ for Mobile query API vastly simplifies the integration of Couchbase Lite within hybrid/cross platform apps.

      N1QL for Mobile is an implementation of the emerging SQL-for-JSON query language specification (SQL++). It provides native, hybrid and cross-platform mobile app developers with a consistent, convenient and flexible interface to query JSON documents within the embedded database using a SQL-based syntax. This means developers can reuse queries across platforms, reducing development, testing and maintenance costs.
