3.1.0 — March 2023
Version 3.1.0 for Objective-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.

On upgrading from a 2.x release, all Couchbase Lite databases will be automatically re-indexed on initial database open. |
New Features
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.

Enhancements
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.

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.

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.
-
The [Database.compact()] method is deprecated (as of 2.8), instead use CBLDatabase.performMaintenance().
