References * [CBL-2832](https://issues.couchbase.com/browse/CBL-2832) — [Implement the API to specify network interface used by the replicator](https://issues.couchbase.com/browse/CBL-2832) ### [](#issues-and-resolutions-3-0-1)Issues and Resolutions #### [](#fixed-issues-2)Fixed Issues * [CBL-2825](https://issues.couchbase.com/browse/CBL-2825) — [Missing \_attachments metadata when pushing updated docs to Sync Gateway](https://issues.couchbase.com/browse/CBL-2825) #### [](#known-issues-4)Known Issues None for this release. ## [](#major)3.0.15 — February 2022 _Quick Links_ [New Features](#new-features-3-0-0) **|** [Enhancements](#improvements-3-0-0) **|** [API Changes](#lbl-api-changes) **|** [Known Issues](#lbl-know-issues-this-release) **|** [Fixed Issues](#lbl-fixed-this-release) **|** [Deprecated in this Release](#lbl-deprecated-this-release) **|** [Removed in this Release](#lbl-removed-this-release) **|** [Support Notices](#lbl-support-notices) **|** > [!IMPORTANT] > 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-3-0-0)New Features #### [](#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. Read More . . . [SQL++ for Mobile](query-n1ql-mobile.md) ### [](#improvements-3-0-0)Enhancements #### [](#auto-purge-on-channel-access-revocation)Auto-purge on Channel Access Revocation An auto-purge feature is introduced for loss of access to channels and the documents in them. This is important for enforcement of data governance and data retention policies. Channels are the fundamental mechanism for enforcement of access control using Sync Gateway. They guarantee that only users with access to a specific channel can access documents in that channel. When a user loses access to a channel (_and so to its documents_) Couchbase Lite clients will auto purge all local documents on devices that belong to the revoked channel (during Pull or PushAndPull replication), unless the user has access to the document via some other channel. Read More . . . [Auto-purge on Channel Access Revocation](replication.md#anchor-auto-purge-on-revoke) #### [](#document-api-support-for-json-data)Document API Support for JSON Data The Couchbase Lite API now offers out-of-the box support for document data in JSON format. This will make it easier for developers' applications to store, transform and manipulate JSON data in the database. The API offers JSON support for Documents, MutableDocuments, Arrays, MutableArrays, Dictionaries, MutableDictionaries and Query Results. Read More . . . [Documents](document.md) | [Blobs](blob.md) #### [](#replicator-change-listeners)Replicator Change Listeners The API is enhanced to allow replicator listeners to be added at any point without requiring a replicator restart. ### [](#other-enhancements)Other Enhancements * [CBL-2633](https://issues.couchbase.com//browse/CBL-2633) — [Update support level and message note of
