# Stock field on the products API and cancelable sessions

*Version 1.255 – released 2026-05-19*

## `stock` field on the products API

`POST /products` now accepts a `stock` field and deprecates the old `quantity` parameter, aligning the API with how inventory is tracked everywhere else.

## Cancel a session while the preview is preparing

You can now cancel a feedback session while its preview is still spinning up, instead of waiting for the deploy to finish before backing out.
