0.1.0

The 0.1.0 release moves the Models SDK onto Ably Pub/Sub v3. The Models SDK runs on end-user devices, so it now works with a client from @ably/pubsub-device, the Ably Pub/Sub package for browsers, mobile apps and other end-user runtimes. @ably/pubsub-device is a peer dependency, so you install it alongside @ably-labs/models.

Below is an overview of the major changes in this release.

Please refer to the upgrade guide for the full details, including a list of all breaking changes and instructions on how to address them.

Ably Pub/Sub v3

• The Models SDK no longer uses the ably package. Create the Pub/Sub client you pass to the Models SDK with createClient from @ably/pubsub-device instead of new Realtime().

Client API naming

• ModelsClient is now an interface. Create clients with the createModelsClient factory function instead of new ModelsClient(). The package no longer has a default export.
• The ably option is renamed pubsubClient.
• The ModelsClient.ably getter is renamed pubsubClient.

Supported platforms changes

• Support for Node.js versions lower than 22 has been dropped.
