## Version 4.0.0-RC2

_2019-06-21_

 *  New: Require Kotlin 1.3.40.
 *  New: Change the Kotlin API from `File.toRequestBody()` to `File.asRequestBody()` and
    `BufferedSource.toResponseBody()` to `BufferedSource.asResponseBody()`. If the returned value

For most migration scenarios, we recommend using the modern JSON Search API (`/api/v1/documents`) instead.

### Admin APIs

All admin APIs require authentication (`-u admin:admin` or Bearer token).

**Base Path**: `/api/admin/`

**Available Endpoints**:
- `POST /backup/upload` - Upload backup/import files
- `GET /backup/export` - Export configurations
