Client Library SDK Improvement

LiveObjects

Version 2.16.0 of the JS Client Library has been released.

This release introduces a redesigned LiveObjects API centered around path-based operations. The new PathObject abstraction provides a more intuitive interaction model where operations resolve at runtime against the current value at a path, rather than being bound to specific object instances.

With this release, the ably-js LiveObjects API is no longer marked as @experimental and is in Public Preview.

Key improvements:

• Resilient subscriptions: Subscribe to paths rather than object instances, so subscriptions automatically follow whatever object exists at that location even when it's replaced.
• Deep subscriptions: Observe changes at any depth below a path with configurable depth control.
• Operation context: Subscription callbacks now receive the complete ObjectMessage that triggered the change, including information about the publishing client and operation details.
• Simplified object creation: Create deeply nested structures in a single operation using LiveMap.create() and LiveCounter.create() static methods, eliminating the risk of orphaned objects.
• Compact representations: New .compact() and .compactJson() methods for converting LiveObjects to plain JavaScript objects.

This release contains breaking changes to the LiveObjects API. See the LiveObjects migration guide for detailed instructions on updating your code.

Chat

New feature

We are excited to announce a new integration for text moderation in Ably Chat. The Azure Content Safety integration leverages powerful AI models to handle inappropriate content before it's published to other users. With it, you can customise what categories are unacceptable, and to what degree of severity, in your chat rooms.

For more information, check out the moderation docs. To get started for free and set up the integrations, log in to your Ably dashboard.

Pub/Sub

For approximately the last year, due to a misconfiguration that affected a subset of accounts, app and account stats for history queries have been undercounted.

Specifically, if a user of one of the affected accounts made a single history query that returned 10 messages, the messages.outbound.rest.all.count stat should have been incremented by 10; instead it was incremented by only 1. (The corresponding data stat was not affected). Since billing is calculated from account stats, the affected accounts may also have been billed less than they should have been.

The fix for this will be rolled out this week.

We know customers expect us to provide stats that they can rely on, and this falls far below our normal standards, for which we apologise.
