packages/matcher/CHANGELOG.md

+## 0.12.0+1
+
+* Fix test files to use `test` instead of `unittest` pkg.
+
+## 0.12.0
+
+* Moved a number of members to the
+  [`unittest`](https://pub.dartlang.org/packages/unittest) package.
+  * `TestFailure`, `ErrorFormatter`, `expect`, `fail`, and 'wrapAsync'.
+  * `completes`, `completion`, `throws`, and `throwsA` Matchers.
+  * The `Throws` class.
+  * All of the `throws...Error` Matchers.
+
+* Removed `FailureHandler`, `DefaultFailureHandler`,
+  `configureExpectFailureHandler`, and `getOrCreateExpectFailureHandler`.
+  Now that `expect` is in the `unittest` package, these are no longer needed.
+
+* Removed the `name` parameter for `isInstanceOf`. This was previously
+  deprecated, and is no longer necessary since all language implementations now
+  support converting the type parameter to a string directly.
+
+## 0.11.4+4
+
+* Deprecate the name parameter to `isInstanceOf`. All language implementations
+  now support converting the type parameter to a string directly.
+
+## 0.11.4+3
+
+* Fix the examples for `equalsIgnoringWhitespace`.
+
+## 0.11.4+2
+
+* Improve the formatting of strings that contain unprintable ASCII characters.
+
+## 0.11.4+1
+
+* Correctly match and print `String`s containing characters that must be
+  represented as escape sequences.
+
+## 0.11.4
+
+* Remove the type checks in the `isEmpty` and `isNotEmpty` matchers and simply
+  access the `isEmpty` respectively `isNotEmpty` fields. This allows them to
+  work with custom collections. See [Issue
+  21792](https://code.google.com/p/dart/issues/detail?id=21792) and [Issue
+  21562](https://code.google.com/p/dart/issues/detail?id=21562)
+
+## 0.11.3+1
+
+* Fix the `prints` matcher test on dart2js.
+
+## 0.11.3
+
+* Add a `prints` matcher that matches output a callback emits via `print`.
+
+## 0.11.2
+
+* Add an `isNotEmpty` matcher.
+
+## 0.11.1+1
+
+* Refactored libraries and tests.
+
+* Fixed spelling mistake.
+
+## 0.11.1
+
+* Added `isNaN` and `isNotNaN` matchers.
+
+## 0.11.0
+
+* Removed deprecated matchers.
+
+## 0.10.1+1
+
+* Get the tests passing when run on dart2js in minified mode.
+
+## 0.10.1
+
+* Compare sets order-independently when using `equals()`.
+
+## 0.10.0+3
+
+* Removed `@deprecated` annotation on matchers due to 
+[Issue 19173](https://code.google.com/p/dart/issues/detail?id=19173)
+
+## 0.10.0+2
+
+* Added types to a number of constants.
+
+## 0.10.0+1
+
+* Matchers related to bad language use have been removed. These represent code
+structure that should rarely or never be validated in tests.
+    * `isAbstractClassInstantiationError`
+    * `throwsAbstractClassInstantiationError`
+    * `isFallThroughError`
+    * `throwsFallThroughError`
+
+* Added types to a number of method arguments.
+
+* The structure of the library and test code has been updated.
