# Changelog
All notable changes to this project will be documented in this file, in reverse chronological order by release.
## 1.7.1 - 2018-02-26
### Added
- Nothing.
### Changed
- [#293](https://github.com/zendframework/zend-diactoros/pull/293) updates
`Uri::getHost()` to cast the value via `strtolower()` before returning it.
While this represents a change, it is fixing a bug in our implementation:
the PSR-7 specification for the method, which follows IETF RFC 3986 section
3.2.2, requires that the host name be normalized to lowercase.
### Deprecated
- Nothing.
### Removed
- Nothing.
### Fixed
- [#290](https://github.com/zendframework/zend-diactoros/pull/290) fixes
`Stream::getSize()` such that it checks that the result of `fstat` was
succesful before attempting to return its `size` member; in the case of an
error, it now returns `null`.
## 1.7.0 - 2018-01-04
### Added
- [#285](https://github.com/zendframework/zend-diactoros/pull/285) adds a new
custom response type, `Zend\Diactoros\Response\XmlResponse`, for generating
responses representing XML. Usage is the same as with the `HtmlResponse` or
`TextResponse`; the response generated will have a `Content-Type:
application/xml` header by default.
- [#280](https://github.com/zendframework/zend-diactoros/pull/280) adds the
response status code/phrase pairing "103 Early Hints" to the
`Response::$phrases` property. This is a new status proposed via
[RFC 8297](https://datatracker.ietf.org/doc/rfc8297/).
- [#279](https://github.com/zendframework/zend-diactoros/pull/279) adds explicit
support for PHP 7.2; previously, we'd allowed build failures, though none
occured; we now require PHP 7.2 builds to pass.
### Changed
- Nothing.
### Deprecated
- Nothing.
### Removed
- Nothing.
### Fixed
- Nothing.
## 1.6.1 - 2017-10-12
### Added
- Nothing.
### Changed
- [#273](https://github.com/zendframework/zend-diactoros/pull/273) updates each
of the SAPI emitter implementations to emit the status line after emitting
other headers; this is done to ensure that the status line is not overridden
by PHP.
### Deprecated
- Nothing.
### Removed
- Nothing.
### Fixed
- [#273](https://github.com/zendframework/zend-diactoros/pull/273) modifies how
the `SapiEmitterTrait` calls `header()` to ensure that a response code is
_always_ passed as the third argument; this is done to prevent PHP from
silently overriding it.
## 1.6.0 - 2017-09-13
### Added
- Nothing.
### Changed
- [#270](https://github.com/zendframework/zend-diactoros/pull/270) changes the
behavior of `Zend\Diactoros\Server`: it no longer creates an output buffer.
- [#270](https://github.com/zendframework/zend-diactoros/pull/270) changes the
behavior of the two SAPI emitters in two backwards-incompatible ways:
- They no longer auto-inject a `Content-Length` header. If you need this
functionality, zendframework/zend-expressive-helpers 4.1+ provides it via
`Zend\Expressive\Helper\ContentLengthMiddleware`.
- They no longer flush the output buffer. Instead, if headers have been sent,
or the output buffer exists and has a non-zero length, the emitters raise an
exception, as mixed PSR-7/output buffer content creates a blocking issue.
If you are emitting content via `echo`, `print`, `var_dump`, etc., or not
catching PHP errors or exceptions, you will need to either fix your
application to always work with a PSR-7 response, or provide your own
emitters that allow mixed output mechanisms.
### Deprecated
- Nothing.
### Removed
- Nothing.
### Fixed
- Nothing.
## 1.5.0 - 2017-08-22
### Added
- [#205](https://github.com/zendframework/zend-diactoros/pull/205) adds support
for PHP 7.2.
- [#250](https://github.com/zendframework/zend-diactoros/pull/250) adds a new
API to `JsonResponse` to avoid the need for decoding the response body in
order to make changes to the underlying content. New methods include:
- `getPayload()`: retrieve the unencoded payload.
- `withPayload($data)`: create a new instance with the given data.
- `getEncodingOptions()`: retrieve the flags to use when encoding the payload
to JSON.
- `withEncodingOptions(int $encodingOptions)`: create a new instance that uses
the provided flags when encoding the payload to JSON.
### Changed
- [#249](https://github.com/zendframework/zend-diactoros/pull/249) changes the
behavior of the various `Uri::with*()` methods slightly: if the value
represents no change, these methods will return the same instance instead of a
new one.
- [#248](https://github.com/zendframework/zend-diactoros/pull/248) changes the
behavior of `Uri::getUserInfo()` slightly: it now (correctly) returns the
percent-encoded values for the user and/or password, per RFC 3986 Section
3.2.1. `withUserInfo()` will percent-encode values, using a mechanism that
prevents double-encoding.
- [#243](https://github.com/zendframework/zend-diactoros/pull/243) changes the
exception messages thrown by `UploadedFile::getStream()` and `moveTo()` when
an upload error exists to include details about the upload error.
- [#233](https://github.com/zendframework/zend-diactoros/pull/233) adds a new
argument to `SapiStreamEmitter::emit`, `$maxBufferLevel` **between** the
`$response` and `$maxBufferLength` arguments. This was done because the
`Server::listen()` method passes only the response and `$maxBufferLevel` to
emitters; previously, this often meant that streams were being chunked 2 bytes
at a time versus the expected default of 8kb.
If you were calling the `SapiStreamEmitter::emit()` method manually
previously, you will need to update your code.
### Deprecated
- Nothing.
### Removed
- [#205](https://github.com/zendframework/zend-diactoros/pull/205) and
[#243](https://github.com/zendframework/zend-diactoros/pull/243) **remove
support for PHP versions prior to 5.6 as well as HHVM**.
### Fixed
- [#248](https://github.com/zendframework/zend-diactoros/pull/248) fixes how the
`Uri` class provides user-info within the URI authority; the value is now
correctly percent-encoded , per RFC 3986 Section 3.2.1.
## 1.4.1 - 2017-08-17
### Added
- Nothing.
### Deprecated
- Nothing.
### Removed
- [#260](https://github.com/zendframework/zend-diactoros/pull/260) removes
support for HHVM, as tests have failed against it for some time.
### Fixed
- [#247](https://github.com/zendframework/zend-diactoros/pull/247) fixes the
`Stream` and `RelativeStream` `__toString()` method implementations to check
if the stream `isSeekable()` before attempting to `rewind()` it, ensuring that
the method does not raise exceptions (PHP does not allow exceptions in that
method). In particular, this fixes an issue when using AWS S3 streams.
- [#252](https://github.com/zendframework/zend-diactoros/pull/252) provides a
fix to the `SapiEmitterTrait` to ensure that any `Set-Cookie` headers in the
response instance do not override those set by PHP when a session is created
and/or regenerated.
- [#257](https://github.com/zendframework/zend-diactoros/pull/257) provides a
fix for the `PhpInputStream::read()` method to ensure string content that
evaluates as empty (including `0`) is still cached.
- [#258](https://github.com/zendframework/zend-diactoros/pull/258) updates the
`Uri::filterPath()` method to allow parens within a URI path, per [RFC 3986
section 3.3](https://tools.ietf.org/html/rfc3986#section-3.3) (parens are
within the character set "sub-delims").
## 1.4.0 - 2017-04-06
### Added
- [#219](https://github.com/zendframework/zend-diactoros/pull/219) adds two new
classes, `Zend\Diactoros\Request\ArraySerializer` and
`Zend\Diactoros\Response\ArraySerializer`. Each exposes the static methods
`toArray()` and `fromArray()`, allowing de/serialization of messages from and
to arrays.
- [#236](https://github.com/zendframework/zend-diactoros/pull/236) adds two new
constants to the `Response` class: `MIN_STATUS_CODE_VALUE` and
`MAX_STATUS_CODE_VALUE`.
### Changes
- [#240](https://github.com/zendframework/zend-diactoros/pull/240) changes the
behavior of `ServerRequestFactory::fromGlobals()` when no `$cookies` argument
is present. Previously, it would use `$_COOKIES`; now, if a `Cookie` header is
present, it will parse and use that to populate the instance instead.
This change allows utilizing cookies that contain period characters (`.`) in
their names (PHP's built-in cookie handling renames these to replace `.` with
`_`, which can lead to synchronization issues with clients).
- [#235](https://github.com/zendframework/zend-diactoros/pull/235) changes the
behavior of `Uri::__toString()` to better follow proscribed behavior in PSR-7.
In particular, prior to this release, if a scheme was missing but an authority
was present, the class was incorrectly returning a value that did not include
a `//` prefix. As of this release, it now does this correctly.
### Deprecated
- Nothing.
### Removed
- Nothing.
### Fixed
- Nothing.
## 1.3.11 - 2017-04-06
### Added
- Nothing.
### Changes
- [#241](https://github.com/zendframework/zend-diactoros/pull/241) changes the
constraint by which the package provides `psr/http-message-implementation` to
simply `1.0` instead of `~1.0.0`, to follow how other implementations provide
PSR-7.
### Deprecated
- Nothing.
### Removed
- Nothing.
### Fixed
- [#161](https://github.com/zendframework/zend-diactoros/pull/161) adds
additional validations to header names and values to ensure no malformed values
are provided.
- [#234](https://github.com/zendframework/zend-diactoros/pull/234) fixes a
number of reason phrases in the `Response` instance, and adds automation from
the canonical IANA sources to ensure any new phrases added are correct.
## 1.3.10 - 2017-01-23
### Added
- Nothing.
### Deprecated
- Nothing.
### Removed
- Nothing.
### Fixed
- [#226](https://github.com/zendframework/zend-diactoros/pull/226) fixed an
issue with the `SapiStreamEmitter` causing the response body to be cast
to `(string)` and also be read as a readable stream, potentially producing
double output.
## 1.3.9 - 2017-01-17
### Added
- Nothing.
### Deprecated
- Nothing.
### Removed
- Nothing.
### Fixed
- [#223](https://github.com/zendframework/zend-diactoros/issues/223)
[#224](https://github.com/zendframework/zend-diactoros/pull/224) fixed an issue
with the `SapiStreamEmitter` consuming too much memory when producing output
for readable bodies.
## 1.3.8 - 2017-01-05
### Added
- Nothing.
### Deprecated
- Nothing.
### Removed
- Nothing.
### Fixed
- [#222](https://github.com/zendframework/zend-diactoros/pull/222) fixes the
`SapiStreamEmitter`'s handling of the `Content-Range` header to properly only
emit a range of bytes if the header value is in the form `bytes {first-last}/length`.
This allows using other range units, such as `items`, without incorrectly
emitting truncated content.
## 1.3.7 - 2016-10-11
### Added
- [#208](https://github.com/zendframework/zend-diactoros/pull/208) adds several
missing response codes to `Zend\Diactoros\Response`, including:
- 226 ('IM used')
- 308 ('Permanent Redirect')
- 444 ('Connection Closed Without Response')
- 499 ('Client Closed Request')
- 510 ('Not Extended')
- 599 ('Network Connect Timeout Error')
- [#211](https://github.com/zendframework/zend-diactoros/pull/211) adds support
for UTF-8 characters in query strings handled by `Zend\Diactoros\Uri`.
### Deprecated
- Nothing.
### Removed
- Nothing.
### Fixed
- Nothing.
## 1.3.6 - 2016-09-07
### Added
- [#170](https://github.com/zendframework/zend-diactoros/pull/170) prepared
documentation for publication at https://zendframework.github.io/zend-diactoros/
- [#165](https://github.com/zendframework/zend-diactoros/pull/165) adds support
for Apache `REDIRECT_HTTP_*` header detection in the `ServerRequestFactory`.
- [#166](https://github.com/zendframework/zend-diactoros/pull/166) adds support
for UTF-8 characters in URI paths.
- [#204](https://github.com/zendframework/zend-diactoros/pull/204) adds testing
against PHP 7.1 release-candidate builds.
### Deprecated
- Nothing.
### Removed
- Nothing.
### Fixed
- [#186](https://github.com/zendframework/zend-diactoros/pull/186) fixes a typo
in a variable name within the `SapiStreamEmitter`.
- [#200](https://github.com/zendframework/zend-diactoros/pull/200) updates the
`SapiStreamEmitter` to implement a check for `isSeekable()` prior to attempts
to rewind; this allows it to work with non-seekable streams such as the
`CallbackStream`.
- [#169](https://github.com/zendframework/zend-diactoros/pull/169) ensures that
response serialization always provides a `\r\n\r\n` sequence following the
headers, even when no message body is present, to ensure it conforms with RFC
7230.
- [#175](https://github.com/zendframework/zend-diactoros/pull/175) updates the
`Request` class to set the `Host` header from the URI host if no header is
already present. (Ensures conformity with PSR-7 specification.)
- [#197](https://github.com/zendframework/zend-diactoros/pull/197) updates the
`Uri` class to ensure that string serialization does not include a colon after
the host name if no port is present in the instance.
## 1.3.5 - 2016-03-17
### Added
- Nothing.
### Deprecated
- Nothing.
### Removed
- Nothing.
### Fixed
- [#160](https://github.com/zendframework/zend-diactoros/pull/160) fixes HTTP
protocol detection in the `ServerRequestFactory` to work correctly with HTTP/2.
## 1.3.4 - 2016-03-17
### Added
- [#119](https://github.com/zendframework/zend-diactoros/pull/119) adds the 451
(Unavailable for Legal Reasons) status code to the `Response` class.
### Deprecated
- Nothing.
### Removed
- Nothing.
### Fixed
- [#117](https://github.com/zendframework/zend-diactoros/pull/117) provides
validation of the HTTP protocol version.
- [#127](https://github.com/zendframework/zend-diactoros/pull/127) now properly
removes attributes with `null` values when calling `withoutAttribute()`.
- [#132](https://github.com/zendframework/zend-diactoros/pull/132) updates the
`ServerRequestFactory` to marshal the request path fragment, if present.
- [#142](https://github.com/zendframework/zend-diactoros/pull/142) updates the
exceptions thrown by `HeaderSecurity` to include the header name and/or
value.
- [#148](https://github.com/zendframework/zend-diactoros/pull/148) fixes several
stream operations to ensure they raise exceptions when the internal pointer
is at an invalid position.
- [#151](https://github.com/zendframework/zend-diactoros/pull/151) ensures
URI fragments are properly encoded.
## 1.3.3 - 2016-01-04
### Added
- Nothing.
### Deprecated
- Nothing.
### Removed
- Nothing.
### Fixed
- [#135](https://github.com/zendframework/zend-diactoros/pull/135) fixes the
behavior of `ServerRequestFactory::marshalHeaders()` to no longer omit
`Cookie` headers from the aggregated headers. While the values are parsed and
injected into the cookie params, it's useful to have access to the raw headers
as well.
## 1.3.2 - 2015-12-22
### Added
- [#124](https://github.com/zendframework/zend-diactoros/pull/124) adds four
more optional arguments to the `ServerRequest` constructor:
- `array $cookies`
- `array $queryParams`
- `null|array|object $parsedBody`
- `string $protocolVersion`
`ServerRequestFactory` was updated to pass values for each of these parameters
when creating an instance, instead of using the related `with*()` methods on
an instance.
### Deprecated
- Nothing.
### Removed
- Nothing.
### Fixed
- [#122](https://github.com/zendframework/zend-diactoros/pull/122) updates the
`ServerRequestFactory` to retrieve the HTTP protocol version and inject it in
the generated `ServerRequest`, which previously was not performed.
## 1.3.1 - 2015-12-16
### Added
- Nothing.
### Deprecated
- Nothing.
### Removed
- Nothing.
### Fixed
- [#113](https://github.com/zendframework/zend-diactoros/pull/113) fixes an
issue in the response serializer, ensuring that the status code in the
deserialized response is an integer.
- [#115](https://github.com/zendframework/zend-diactoros/pull/115) fixes an
issue in the various text-basd response types (`TextResponse`, `HtmlResponse`,
and `JsonResponse`); due to the fact that the constructor was not
rewinding the message body stream, `getContents()` was thus returning `null`,
as the pointer was at the end of the stream. The constructor now rewinds the
stream after populating it in the constructor.
## 1.3.0 - 2015-12-15
### Added
- [#110](https://github.com/zendframework/zend-diactoros/pull/110) adds
`Zend\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.
- [#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.
### Deprecated
- Nothing.
### Removed
- Nothing.
### Fixed
- Nothing.
## 1.2.1 - 2015-12-15
### Added
- Nothing.
### Deprecated
- Nothing.
### Removed
- Nothing.
### Fixed
- [#101](https://github.com/zendframework/zend-diactoros/pull/101) fixes the
`withHeader()` implementation to ensure that if the header existed previously
but using a different casing strategy, the previous version will be removed
in the cloned instance.
- [#103](https://github.com/zendframework/zend-diactoros/pull/103) fixes the
constructor of `Response` to ensure that null status codes are not possible.
- [#99](https://github.com/zendframework/zend-diactoros/pull/99) fixes
validation of header values submitted via request and response constructors as
follows:
- numeric (integer and float) values are now properly allowed (this solves
some reported issues with setting Content-Length headers)
- invalid header names (non-string values or empty strings) now raise an
exception.
- invalid individual header values (non-string, non-numeric) now raise an
exception.
## 1.2.0 - 2015-11-24
### Added
- [#88](https://github.com/zendframework/zend-diactoros/pull/88) updates the
`SapiEmitter` to emit a `Content-Length` header with the content length as
reported by the response body stream, assuming that
`StreamInterface::getSize()` returns an integer.
- [#77](https://github.com/zendframework/zend-diactoros/pull/77) adds a new
response type, `Zend\Diactoros\Response\TextResponse`, for returning plain
text responses. By default, it sets the content type to `text/plain;
charset=utf-8`; per the other response types, the signature is `new
TextResponse($text, $status = 200, array $headers = [])`.
- [#90](https://github.com/zendframework/zend-diactoros/pull/90) adds a new
`Zend\Diactoros\CallbackStream`, allowing you to back a stream with a PHP
callable (such as a generator) to generate the message content. Its
constructor accepts the callable: `$stream = new CallbackStream($callable);`
### Deprecated
- Nothing.
### Removed
- Nothing.
### Fixed
- [#77](https://github.com/zendframework/zend-diactoros/pull/77) updates the
`HtmlResponse` to set the charset to utf-8 by default (if no content type
header is provided at instantiation).
## 1.1.4 - 2015-10-16
### Added
- [#98](https://github.com/zendframework/zend-diactoros/pull/98) adds
`JSON_UNESCAPED_SLASHES` to the default `json_encode` flags used by
`Zend\Diactoros\Response\JsonResponse`.
### Deprecated
- Nothing.
### Removed
- Nothing.
### Fixed
- [#96](https://github.com/zendframework/zend-diactoros/pull/96) updates
`withPort()` to allow `null` port values (indicating usage of default for
the given scheme).
- [#91](https://github.com/zendframework/zend-diactoros/pull/91) fixes the
logic of `withUri()` to do a case-insensitive check for an existing `Host`
header, replacing it with the new one.
## 1.1.3 - 2015-08-10
### Added
- [#73](https://github.com/zendframework/zend-diactoros/pull/73) adds caching of
the vendor directory to the Travis-CI configuration, to speed up builds.
### Deprecated
- Nothing.
### Removed
- Nothing.
### Fixed
- [#71](https://github.com/zendframework/zend-diactoros/pull/71) fixes the
docblock of the `JsonResponse` constructor to typehint the `$data` argument
as `mixed`.
- [#73](https://github.com/zendframework/zend-diactoros/pull/73) changes the
behavior in `Request` such that if it marshals a stream during instantiation,
the stream is marked as writeable (specifically, mode `wb+`).
- [#85](https://github.com/zendframework/zend-diactoros/pull/85) updates the
behavior of `Zend\Diactoros\Uri`'s various `with*()` methods that are
documented as accepting strings to raise exceptions on non-string input.
Previously, several simply passed non-string input on verbatim, others
normalized the input, and a few correctly raised the exceptions. Behavior is
now consistent across each.
- [#87](https://github.com/zendframework/zend-diactoros/pull/87) fixes
`UploadedFile` to ensure that `moveTo()` works correctly in non-SAPI
environments when the file provided to the constructor is a path.
## 1.1.2 - 2015-07-12
### Added
- Nothing.
### Deprecated
- Nothing.
### Removed
- Nothing.
### Fixed
- [#67](https://github.com/zendframework/zend-diactoros/pull/67) ensures that
the `Stream` class only accepts `stream` resources, not any resource.
## 1.1.1 - 2015-06-25
### Added
- Nothing.
### Deprecated
- Nothing.
### Removed
- Nothing.
### Fixed
- [#64](https://github.com/zendframework/zend-diactoros/pull/64) fixes the
behavior of `JsonResponse` with regards to serialization of `null` and scalar
values; the new behavior is to serialize them verbatim, without any casting.
## 1.1.0 - 2015-06-24
### Added
- [#52](https://github.com/zendframework/zend-diactoros/pull/52),
[#58](https://github.com/zendframework/zend-diactoros/pull/58),
[#59](https://github.com/zendframework/zend-diactoros/pull/59), and
[#61](https://github.com/zendframework/zend-diactoros/pull/61) create several
custom response types for simplifying response creation:
- `Zend\Diactoros\Response\HtmlResponse` accepts HTML content via its
constructor, and sets the `Content-Type` to `text/html`.
- `Zend\Diactoros\Response\JsonResponse` accepts data to serialize to JSON via
its constructor, and sets the `Content-Type` to `application/json`.
- `Zend\Diactoros\Response\EmptyResponse` allows creating empty, read-only
responses, with a default status code of 204.
- `Zend\Diactoros\Response\RedirectResponse` allows specifying a URI for the
`Location` header in the constructor, with a default status code of 302.
Each also accepts an optional status code, and optional headers (which can
also be used to provide an alternate `Content-Type` in the case of the HTML
and JSON responses).
### Deprecated
- Nothing.
### Removed
- [#43](https://github.com/zendframework/zend-diactoros/pull/43) removed both
`ServerRequestFactory::marshalUri()` and `ServerRequestFactory::marshalHostAndPort()`,
which were deprecated prior to the 1.0 release.
### Fixed
- [#29](https://github.com/zendframework/zend-diactoros/pull/29) fixes request
method validation to allow any valid token as defined by [RFC
7230](http://tools.ietf.org/html/rfc7230#appendix-B). This allows usage of
custom request methods, vs a static, hard-coded list.
## 1.0.5 - 2015-06-24
### Added
- Nothing.
### Deprecated
- Nothing.
### Removed
- Nothing.
### Fixed
- [#60](https://github.com/zendframework/zend-diactoros/pull/60) fixes
the behavior of `UploadedFile` when the `$errorStatus` provided at
instantiation is not `UPLOAD_ERR_OK`. Prior to the fix, an
`InvalidArgumentException` would occur at instantiation due to the fact that
the upload file was missing or invalid. With the fix, no exception is raised
until a call to `moveTo()` or `getStream()` is made.
## 1.0.4 - 2015-06-23
This is a security release.
A patch has been applied to `Zend\Diactoros\Uri::filterPath()` that ensures that
paths can only begin with a single leading slash. This prevents the following
potential security issues:
- XSS vectors. If the URI path is used for links or form targets, this prevents
cases where the first segment of the path resembles a domain name, thus
creating scheme-relative links such as `//example.com/foo`. With the patch,
the leading double slash is reduced to a single slash, preventing the XSS
vector.
- Open redirects. If the URI path is used for `Location` or `Link` headers,
without a scheme and authority, potential for open redirects exist if clients
do not prepend the scheme and authority. Again, preventing a double slash
corrects the vector.
If you are using `Zend\Diactoros\Uri` for creating links, form targets, or
redirect paths, and only using the path segment, we recommend upgrading
immediately.
### Added
- [#25](https://github.com/zendframework/zend-diactoros/pull/25) adds
documentation. Documentation is written in markdown, and can be converted to
HTML using [bookdown](http://bookdown.io). New features now MUST include
documentation for acceptance.
### Deprecated
- Nothing.
### Removed
- Nothing.
### Fixed
- [#51](https://github.com/zendframework/zend-diactoros/pull/51) fixes
`MessageTrait::getHeaderLine()` to return an empty string instead of `null` if
the header is undefined (which is the behavior specified in PSR-7).
- [#57](https://github.com/zendframework/zend-diactoros/pull/57) fixes the
behavior of how the `ServerRequestFactory` marshals upload files when they are
represented as a nested associative array.
- [#49](https://github.com/zendframework/zend-diactoros/pull/49) provides several
fixes that ensure that Diactoros complies with the PSR-7 specification:
- `MessageInterface::getHeaderLine()` MUST return a string (that string CAN be
empty). Previously, Diactoros would return `null`.
- If no `Host` header is set, the `$preserveHost` flag MUST be ignored when
calling `withUri()` (previously, Diactoros would not set the `Host` header
if `$preserveHost` was `true`, but no `Host` header was present).
- The request method MUST be a string; it CAN be empty. Previously, Diactoros
would return `null`.
- The request MUST return a `UriInterface` instance from `getUri()`; that
instance CAN be empty. Previously, Diactoros would return `null`; now it
lazy-instantiates an empty `Uri` instance on initialization.
- [ZF2015-05](http://framework.zend.com/security/advisory/ZF2015-05) was
addressed by altering `Uri::filterPath()` to prevent emitting a path prepended
with multiple slashes.
## 1.0.3 - 2015-06-04
### Added
- [#48](https://github.com/zendframework/zend-diactoros/pull/48) drops the
minimum supported PHP version to 5.4, to allow an easier upgrade path for
Symfony 2.7 users, and potential Drupal 8 usage.

## 1.0.2 - 2015-06-04
### Added
- [#27](https://github.com/zendframework/zend-diactoros/pull/27) adds phonetic
pronunciation of "Diactoros" to the README file.
- [#36](https://github.com/zendframework/zend-diactoros/pull/36) adds property
annotations to the class-level docblock of `Zend\Diactoros\RequestTrait` to
ensure properties inherited from the `MessageTrait` are inherited by
implementations.
### Deprecated
- Nothing.
### Removed
- Nothing.
-
### Fixed
- [#41](https://github.com/zendframework/zend-diactoros/pull/41) fixes the
namespace for test files to begin with `ZendTest` instead of `Zend`.
- [#46](https://github.com/zendframework/zend-diactoros/pull/46) ensures that
the cookie and query params for the `ServerRequest` implementation are
initialized as arrays.
- [#47](https://github.com/zendframework/zend-diactoros/pull/47) modifies the
internal logic in `HeaderSecurity::isValid()` to use a regular expression
instead of character-by-character comparisons, improving performance.
## 1.0.1 - 2015-05-26
### Added
- [#10](https://github.com/zendframework/zend-diactoros/pull/10) adds
`Zend\Diactoros\RelativeStream`, which will return stream contents relative to
a given offset (i.e., a subset of the stream). `AbstractSerializer` was
updated to create a `RelativeStream` when creating the body of a message,
which will prevent duplication of the stream in-memory.
- [#21](https://github.com/zendframework/zend-diactoros/pull/21) adds a
`.gitattributes` file that excludes directories and files not needed for
production; this will further minify the package for production use cases.
### Deprecated
- Nothing.
### Removed
- Nothing.
### Fixed
- [#9](https://github.com/zendframework/zend-diactoros/pull/9) ensures that
attributes are initialized to an empty array, ensuring that attempts to
retrieve single attributes when none are defined will not produce errors.
- [#14](https://github.com/zendframework/zend-diactoros/pull/14) updates
`Zend\Diactoros\Request` to use a `php://temp` stream by default instead of
`php://memory`, to ensure requests do not create an out-of-memory condition.
- [#15](https://github.com/zendframework/zend-diactoros/pull/15) updates
`Zend\Diactoros\Stream` to ensure that write operations trigger an exception
if the stream is not writeable. Additionally, it adds more robust logic for
determining if a stream is writeable.
## 1.0.0 - 2015-05-21
First stable release, and first release as `zend-diactoros`.
