packages/matcher/CHANGELOG.md

+## 0.12.1+1
+
+* Produce a better error message when a `CustomMatcher`'s feature throws.
+
+## 0.12.1
+
+* Add containsAllInOrder matcher for Iterables
+
+## 0.12.0+2
+
+* Fix all strong-mode warnings.
+
 ## 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+6
+
+* Fix a bug introduced in 0.11.4+5 in which operator matchers broke when taking
+  lists of matchers.
+
+## 0.11.4+5
+
+* Fix all strong-mode warnings.
+
 ## 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

 * Matchers related to bad language use have been removed. These represent code
 structure that should rarely or never be validated in tests.

     * `throwsAbstractClassInstantiationError`
     * `isFallThroughError`
     * `throwsFallThroughError`
 
 * Added types to a number of method arguments.
