+## 1.14.1
+
+* Make `Equality` implementations accept `null` as argument to `hash`.
+
+## 1.14.0
+
+* Add `CombinedListView`, a view of several lists concatenated together.
+* Add `CombinedIterableView`, a view of several iterables concatenated together.
+* Add `CombinedMapView`, a view of several maps concatenated together.
+
+## 1.13.0
+
+* Add `EqualityBy`
+
+## 1.12.0
+
+* Add `CaseInsensitiveEquality`.
+
+* Fix bug in `equalsIgnoreAsciiCase`.
+
+## 1.11.0
+
+* Add `EqualityMap` and `EqualitySet` classes which use `Equality` objects for
+  key and element equality, respectively.
+
+## 1.10.1
+
+* `Set.difference` now takes a `Set<Object>` as argument.
+
+## 1.9.1
+
+* Fix some documentation bugs.
+
+## 1.9.0
+
+* Add a top-level `stronglyConnectedComponents()` function that returns the
+  strongly connected components in a directed graph.
+
+## 1.8.0
+
+* Add a top-level `mapMap()` function that works like `Iterable.map()` on a
+  `Map`.
+
+* Add a top-level `mergeMaps()` function that creates a new map with the
+  combined contents of two existing maps.
+
+* Add a top-level `groupBy()` function that converts an `Iterable` to a `Map` by
+  grouping its elements using a function.
+
+* Add top-level `minBy()` and `maxBy()` functions that return the minimum and
+  maximum values in an `Iterable`, respectively, ordered by a derived value.
+
+* Add a top-level `transitiveClosure()` function that returns the transitive
+  closure of a directed graph.
+
+## 1.7.0
+
+* Add a `const UnmodifiableSetView.empty()` constructor.
+
+## 1.6.0
+
+* Add a `UnionSet` class that provides a view of the union of a set of sets.
+
+* Add a `UnionSetController` class that provides a convenient way to manage the
+  contents of a `UnionSet`.
+
+* Fix another incorrectly-declared generic type.
+
+## 1.5.1
+
+* Fix an incorrectly-declared generic type.
+
+## 1.5.0
+
+* Add `DelegatingIterable.typed()`, `DelegatingList.typed()`,
+  `DelegatingSet.typed()`, `DelegatingMap.typed()`, and
+  `DelegatingQueue.typed()` static methods. These wrap untyped instances of
+  these classes with the correct type parameter, and assert the types of values
+  as they're accessed.
+
+* Fix the types for `binarySearch()` and `lowerBound()` so they no longer
+  require all arguments to be comparable.
+
+* Add generic annotations to `insertionSort()` and `mergeSort()`.
+
+## 1.4.1
+
+* Fix all strong mode warnings.
+
+## 1.4.0
+
+* Add a `new PriorityQueue()` constructor that forwards to `new
+  HeapPriorityQueue()`.
+
+* Deprecate top-level libraries other than `package:collection/collection.dart`,
+  which exports these libraries' interfaces.
+
+## 1.3.0
+
+* Add `lowerBound` to binary search for values that might not be present.
+
+* Verify that the is valid for `CanonicalMap.[]`.
+
 ## 1.2.0
 
 * Add string comparators that ignore ASCII case and sort numbers numerically.
 
 ## 1.1.3
 
 * Fix type inconsistencies with `Map` and `Set`.
 
 ## 1.1.2
 
@@ skipping 16 matching lines @@
 
 * Fix all analyzer hints.
 
 ## 0.9.3
 
 * Add a `MapKeySet` class that exposes an unmodifiable `Set` view of a `Map`'s
   keys.
 
 * Add a `MapValueSet` class that takes a function from values to keys and uses
   it to expose a `Set` view of a `Map`'s values.
