Based on https://github.com/zendframework/zend-diactoros/releases/tag/1.3.0 (commit 63e4a7610e0c4064db9403ecfa88abf8831cd77b in this repo)

Added
-----

- [zendframework/zend-diactoros#110](https://github.com/zendframework/zend-diactoros/pull/110) adds
  `Laminas\Diactoros\Response\SapiEmitterTrait`, which provides the following
  private method definitions:
  - `injectContentLength()`
  - `emitStatusLine()`
  - `emitHeaders()`
  - `flush()`
  - `filterHeader()`
  The `SapiEmitter` implementation has been updated to remove those methods and
  instead compose the trait.
- [zendframework/zend-diactoros#111](https://github.com/zendframework/zend-diactoros/pull/111) adds
  a new emitter implementation, `SapiStreamEmitter`; this emitter type will
  loop through the stream instead of emitting it in one go, and supports content
  ranges.
