# Changelog

> Additions and compatibility notes for the Sparkles Sandbox API.

## 2026-09-03

* Added `GET /sandboxes/{id}/files/download`, which streams one working-tree file from a running sandbox as an attachment over the sandbox ACP connection.

## 2026-08-06

* Added organization-bound sandboxes with create, get, list, follow-up, interrupt, approval, terminate, file-read, and draft pull-request operations.
* Added a fetch-authenticated SSE stream and JSON event history using the versioned `sandbox.event` envelope.
* Added independent `sandbox-create` and `stream-connect` limits while retaining the 600 requests-per-minute general limit.
