+## 0.2.0 - 2017-05-30
+
+### Added
+
+- [#4](https://github.com/weierophinney/problem-details/pull/4) adds
+  `ProblemDetailsReponseFactoryFactory` for generating a
+  `ProblemDetailsResponseFactory` instance.
+
+### Changed
+
+- [#4](https://github.com/weierophinney/problem-details/pull/4) changes the
+  `ProblemDetailsResponseFactory` in several ways:
+  - It is now instantiable. The constructor accepts a boolean indicating debug
+    status (`false` by default), an integer bitmask of JSON encoding flags, a
+    PSR-7 `ResponseInterface` instance, and a callable factory for generating a
+    writable PSR-7 `StreamInterface` for the final problem details response
+    content.
+  - `createResponse()` is now an instance method, and its first argument is no
+    longer an `Accept` header, but a PSR-7 `ServerRequestInterface` instance.
+  - `createResponseFromThrowable()` is now an instance method, and its first
+    argument is no longer an `Accept` header, but a PSR-7
+    `ServerRequestInterface` instance.
+
+- [#4](https://github.com/weierophinney/problem-details/pull/4) changes the
+  `ProblemDetailsMiddleware`; it now composes a `ProblemDetailsResponseFactory`
+  insteead of an `isDebug` flag. Additionally, it no longer wraps processing of
+  the delegate in a try/catch block if the request cannot accept JSON or XML.
+
+- [#4](https://github.com/weierophinney/problem-details/pull/4) changes the
+  `ProblemDetailsMiddlewareFactory` to inject the `ProblemDetailsMiddleware`
+  with a `ProblemDetailsResponseFactory` instead of an `isDebug` flag.
+
+### Deprecated
+
+- Nothing.
+
+### Removed
+
+- [#4](https://github.com/weierophinney/problem-details/pull/4) removes the
+  `ProblemDetailsJsonResponse`; use the `ProblemDetailsResponseFactory` instead.
+
+- [#4](https://github.com/weierophinney/problem-details/pull/4) removes the
+  `ProblemDetailsXmlResponse`; use the `ProblemDetailsResponseFactory` instead.
+
+- [#4](https://github.com/weierophinney/problem-details/pull/4) removes the
+  `CommonProblemDetails` trait; the logic is now incorporated in the
+  `ProblemDetailsResponseFactory`.
+
+- [#4](https://github.com/weierophinney/problem-details/pull/4) removes the
+  `ProblemDetailsResponse` interface; PSR-7 response prototypes are now used
+  instead.
+
+### Fixed
+
+- [#4](https://github.com/weierophinney/problem-details/pull/4) updates JSON
+  response generation to allow specifying your own JSON encoding flags. By
+  default, it now does pretty JSON, with unescaped slashes and unicode.
+
