- [#307](https://github.com/zendframework/zend-diactoros/pull/307) adds the following functions under the `Zend\Diactoros` namespace, each of
  which may be used to derive artifacts from SAPI supergloabls for the purposes
  of generating a `ServerRequest` instance:
  - `normalizeServer(array $server, callable $apacheRequestHeaderCallback = null) : array`
    (main purpose is to aggregate the `Authorization` header in the SAPI params
    when under Apache)
  - `marshalProtocolVersionFromSapi(array $server) : string`
  - `marshalMethodFromSapi(array $server) : string`
  - `marshalUriFromSapi(array $server, array $headers) : Uri`
  - `marshalHeadersFromSapi(array $server) : array`
  - `parseCookieHeader(string $header) : array`
  - `createUploadedFile(array $spec) : UploadedFile` (creates the instance from
    a normal `$_FILES` entry)
  - `normalizeUploadedFiles(array $files) : UploadedFileInterface[]` (traverses
    a potentially nested array of uploaded file instances and/or `$_FILES`
    entries, including those aggregated under mod_php, php-fpm, and php-cgi in
    order to create a flat array of `UploadedFileInterface` instances to use in a
    request)

Changed

- Nothing.

Deprecated
----------

- [#307](https://github.com/zendframework/zend-diactoros/pull/307) deprecates `ServerRequestFactory::normalizeServer()`; the method is
  no longer used internally, and users should instead use `Zend\Diactoros\normalizeServer()`,
  to which it proxies.

- [#307](https://github.com/zendframework/zend-diactoros/pull/307) deprecates `ServerRequestFactory::marshalHeaders()`; the method is
  no longer used internally, and users should instead use `Zend\Diactoros\marshalHeadersFromSapi()`,
  to which it proxies.

- [#307](https://github.com/zendframework/zend-diactoros/pull/307) deprecates `ServerRequestFactory::marshalUriFromServer()`; the method
  is no longer used internally. Users should use `marshalUriFromSapi()` instead.

- [#307](https://github.com/zendframework/zend-diactoros/pull/307) deprecates `ServerRequestFactory::marshalRequestUri()`. the method is no longer
  used internally, and currently proxies to `marshalUriFromSapi()`, pulling the
  discovered path from the `Uri` instance returned by that function. Users
  should use `marshalUriFromSapi()` instead.

- [#307](https://github.com/zendframework/zend-diactoros/pull/307) deprecates `ServerRequestFactory::marshalHostAndPortFromHeaders()`; the method
  is no longer used internally, and currently proxies to `marshalUriFromSapi()`,
  pulling the discovered host and port from the `Uri` instance returned by that
  function. Users should use `marshalUriFromSapi()` instead.

- [#307](https://github.com/zendframework/zend-diactoros/pull/307) deprecates `ServerRequestFactory::getHeader()`; the method is no longer
  used internally. Users should copy and paste the functionality into their own
  applications if needed, or rely on headers from a fully-populated `Uri`
  instance instead.

- [#307](https://github.com/zendframework/zend-diactoros/pull/307) deprecates `ServerRequestFactory::stripQueryString()`; the method is no longer
  used internally, and users can mimic the functionality via the expression
  `$path = explode('?', $path, 2)[0];`.

- [#307](https://github.com/zendframework/zend-diactoros/pull/307) deprecates `ServerRequestFactory::normalizeFiles()`; the functionality
  is no longer used internally, and users can use `normalizeUploadedFiles()` as
  a replacement.

- [#303](https://github.com/zendframework/zend-diactoros/pull/303) deprecates `Zend\Diactoros\Response\EmitterInterface` and its various implementations. These are now provided via the
  [zendframework/zend-httphandlerrunner](https://docs.zendframework.com/zend-httphandlerrunner) package as 1:1 substitutions.

- [#303](https://github.com/zendframework/zend-diactoros/pull/303) deprecates the `Zend\Diactoros\Server` class. Users are directed to the `RequestHandlerRunner` class from the
  [zendframework/zend-httphandlerrunner](https://docs.zendframework.com/zend-httphandlerrunner) package as an alternative.
