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.

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.

Deprecated in this Release
Items (features and-or functionality) are marked as deprecated when a more current, and usually enhanced, alternative is available.
Whilst the deprecated item will remain usable, it is no longer supported, and will be removed in a future release — see also: Removed in this Release You should plan to move to an alternative, supported, solution as soon as practical.
None for this release.
