+## 1.4.0-wip
+
+* The type of the `buffer` constructor argument to `TypedDataBuffer` is now
+  `TypeDataList<E>` (instead of `List<E>`). While this is breaking change
+  statically there was a runtime cast that makes this change a no-op in
+  practice. 
+* Require Dart 3.5
+
+## 1.3.2
+
+* Added package topics to the pubspec file.
+* Require Dart 2.17.
+
+## 1.3.1
+
+* Switch to using `package:lints`.
+* Populate the pubspec `repository` field.
+
+## 1.3.0
+
+* Stable release for null safety.
+* Update SDK constraints to `>=2.12.0-0 <3.0.0` based on beta release
+  guidelines.
+
+## 1.2.0
+
+* Add typed queue classes such as `Uint8Queue`. These classes implement both
+  `Queue` and `List` with a highly-efficient typed-data-backed implementation.
+  Their `sublist()` methods also return typed data classes.
+* Update min Dart SDK to `2.4.0`.
+
+## 1.1.6
+
+* Set max SDK version to `<3.0.0`, and adjust other dependencies.
+
+## 1.1.5
+
+* Undo unnecessary SDK version constraint tweak.
+
+## 1.1.4
+
+* Expand the SDK version constraint to include `<2.0.0-dev.infinity`.
+
+## 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

+Helper libraries for working with typed data lists.
+
+The `typed_data` package contains utility functions and classes that makes working with typed data lists easier.
+
+## Using
+
+The `typed_data` package can be imported using:
+
+```dart
+import 'package:typed_data/typed_data.dart';
+```
+
+## Typed buffers
+
+Typed buffers are growable lists backed by typed arrays. These are similar to
+the growable lists created by `<int>[]` or `<double>[]`, but store typed data
+like a typed data list.
