# What’s New

> [!NOTE]
> Couchbase Lite 3.0 introduces some breaking changes.  
> If you are upgrading from 2.x, please refer to the appropriate upgrade page — see: [Upgrading](#lbl-upgrade)

## [](#release-3-0-february-2022)Release 3.0 (February 2022)

Couchbase Lite Release 3.0 introduces enhanced platform support with the introduction of:

* Couchbase Lite for C — extending your apps beyond mobile to the IoT application space
* Couchbase Lite for Android now offers a new, fully supported, out-of-the-box, idiomatic api for Kotlin
* SQL++ for Mobile (also referred to as N1QL) --supporting the emerging SQL for JSON technology, SQL++.

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

#### [](#couchbase-lite-for-c)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](c/supported-os.md).

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.

#### [](#kotlin-support-in-android)Kotlin Support in Android

_Couchbase Lite for Android_ delivers an idiomatic Kotlin API out-of-the-box. This enables seamless integration with Android apps developed in Kotlin without the need for custom extensions.

Kotlin developers can now build apps using [common Kotlin Patterns](https://developer.android.com/kotlin/common-patterns) and use familiar Kotlin features such as:

* Nullability annotations
* Named parameters
* Kotlin Flows

Java support and functionality continues for Android. You can choose whether to use the Kotlin extensions API or continue using the Java api.

#### [](#sqln1ql-query-strings)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.
