+## 1.1.3
+
+* Fix all strong-mode warnings.
+
+## 1.1.2
+
+* Fix a bug where `TypedDataBuffer.insertAll` could fail to insert some elements
+  of an `Iterable`.
+
+## 1.1.1
+
+* Optimize `insertAll` with an `Iterable` argument and no end-point.
+
+## 1.1.0
+
+* Add `start` and `end` parameters to the `addAll()` and `insertAll()` methods
+  for the typed data buffer classes. These allow efficient concatenation of
+  slices of existing typed data.
+
+* Make `addAll()` for typed data buffer classes more efficient for lists,
+  especially typed data lists.
+
+## 1.0.0
+
+* ChangeLog starts here
