+## 2.2.2-wip
+
+- Suppress warnings previously printed to `stdout` when parsing YAML internally.
+- Fix error thrown when inserting duplicate keys to different maps in the same
+  list.
+  ([#69](https://github.com/dart-lang/yaml_edit/issues/69))
+
+- Fix error thrown when inserting in nested list using `spliceList` method
+  ([#83](https://github.com/dart-lang/yaml_edit/issues/83))
+
+- Fix error thrown when string has spaces when applying `ScalarStyle.FOLDED`.
+  ([#41](https://github.com/dart-lang/yaml_edit/issues/41)). Resolves
+  ([[#86](https://github.com/dart-lang/yaml_edit/issues/86)]).
+
+- Require Dart 3.1
+
+## 2.2.1
+
+- Require Dart 3.0
+- Fix removal of last key in blockmap when key has no value
+  ([#55](https://github.com/dart-lang/yaml_edit/issues/55)).
+
+## 2.2.0
+
+- Fix inconsistent line endings when inserting maps into a document using `\r\n`.
+  ([#65](https://github.com/dart-lang/yaml_edit/issues/65))
+
+- `AliasError` is changed to `AliasException` and exposed in the public API.
+
+  All node-mutating methods on `YamlEditor`, i.e. `update()`, `appendToList()`,
+  `prependToList()`, `insertIntoList()`, `spliceList()`, `remove()` will now
+  throw an exception instead of an error when encountering an alias on the path
+  to modify.
+
+  This allows catching and handling when this is happening.
+
+## 2.1.1
+
+- Require Dart 2.19
+
+## 2.1.0
+
+- **Breaking** `wrapAsYamlNode(value, collectionStyle, scalarStyle)` will apply
+  `collectionStyle` and `scalarStyle` recursively when wrapping a children of
+  `Map` and `List`.
+  While this may change the style of the YAML documents written by applications
+  that rely on the old behavior, such YAML documents should still be valid.
+  Hence, we hope it is reasonable to make this change in a minor release.
+- Fix for cases that can't be encoded correctly with
+  `scalarStyle: ScalarStyle.SINGLE_QUOTED`.
+- Fix YamlEditor `appendToList` and `insertIntoList` functions inserts new item into next yaml item
+  rather than at end of list.
+  ([#23](https://github.com/dart-lang/yaml_edit/issues/23))
+
+## 2.0.3
+
+- Updated the value of the pubspec `repository` field.
+
+## 2.0.2
+
+- Fix trailing whitespace after adding new key with block-value to map
+  ([#15](https://github.com/dart-lang/yaml_edit/issues/15)).
+- Updated `repository` and other meta-data in `pubspec.yaml`.
+
+## 2.0.1
+
+- License changed to BSD, as this package is now maintained by the Dart team.
+- Fixed minor lints.
+
+## 2.0.0
+
+- Migrated to null-safety.
+- API will no-longer return `null` in-place of a `YamlNode`, instead a
+  `YamlNode` with `YamlNode.value == null` should be used. These are easily
+  created with `wrapAsYamlNode(null)`.
+
+## 1.0.3
+
+- Fixed bug in adding an empty map as a map value.
+
+## 1.0.2
+
+- Throws an error if the final YAML after edit is not parsable.
+- Fixed bug in adding to empty map values, when it is followed by other content.
+
+## 1.0.1
+
+- Updated behavior surrounding list and map removal.
+- Fixed bug in dealing with empty values.
+
+## 1.0.0
+
+- Initial release.

+
+A library for [YAML](https://yaml.org) manipulation while preserving comments.
+
+## Usage
+
+A simple usage example:
+
+```dart
+import 'package:yaml_edit/yaml_edit.dart';
+
+void main() {
+  final yamlEditor = YamlEditor('{YAML: YAML}');
+  yamlEditor.update(['YAML'], "YAML Ain't Markup Language");
+  print(yamlEditor);
+  // Expected output:
+  // {YAML: YAML Ain't Markup Language}
+}
+```
+
+### Example: Converting JSON to YAML (block formatted)
+
+```dart
+void main() {
+  final jsonString = r'''
+{
+  "key": "value",
+  "list": [
+    "first",
+    "second",
+    "last entry in the list"
+  ],
+  "map": {
+    "multiline": "this is a fairly long string with\nline breaks..."
+  }
+}
+''';
+  final jsonValue = json.decode(jsonString);
+
+  // Convert jsonValue to YAML
+  final yamlEditor = YamlEditor('');
+  yamlEditor.update([], jsonValue);
+  print(yamlEditor.toString());
+}
+```
+
+## Testing
+
+Testing is done in two strategies: Unit testing (`/test/editor_test.dart`) and
+Golden testing (`/test/golden_test.dart`). More information on Golden testing
+and the input/output format can be found at `/test/testdata/README.md`.
+
+These tests are automatically run with `pub run test`.
+
+## Limitations
+
+1. Users are not allowed to define tags in the modifications.
+2. Map keys will always be added in the flow style.
