Ably

Documentation

You can now read and update LiveObjects from the HTTP client, with no realtime connection. This suits server code that needs to inspect or change object state in response to a request, such as seeding a counter or updating a map from a backend job. Every HTTP channel now has a channel.object property. It is built into the HTTP client, so you don't need the liveobjects plugin to use it.

This 3.1.0 release makes it easier to publish from backend workers. If your server publishes from many concurrent jobs, createRealtimeChannelPool lets them share a small, fixed set of connections instead of opening one per job. If you run Temporal workflows, the new Temporal plugin lets workflow code call the Ably HTTP API directly, and retries and replays don't send duplicate messages.

The 4.2.1 release upgrades Guava to 33.7.2-jre to address security vulnerability CVE-2026-102554. There are no other changes. For the full changelog, please visit the GitHub release page.
