# v1.2.9 — Aug 4, 2026

<Badge>Latest</Badge>

**Fixes**

* Site `environment` is preserved end-to-end (HTML bootstrap → SDK → flush headers). Omitted environment now defaults to `development` instead of being forced to `production`.
* CDN / npm packages send `X-Environment` on event and replay flushes so ingest can attribute traffic correctly.

```ts theme={null}
init({ token: 'YOUR_TOKEN', environment: 'production' }) // or 'development'
```
