+## [1.4.0]
+- Added `filterQuality` property to control the performance vs quality trade-off to use when drawing images
+
+## [1.3.0]
+- Added support for rounded corners on shapes and rects
+- Add support for text in dynamic properties (`ValueDelegate`)
+
+Example:
+
+```dart
+Lottie.asset(
+  'assets/DynamicText.json',
+  delegates: LottieDelegates(values: [
+    ValueDelegate.text(
+      ['Text layer'], // The path to the text element to change
+      value: 'The new text',
+    ),
+  ]),
+)
+```
+
+- Improve stroke with offset
+- Add support for reversed polystar paths
+- Enforce order of operations to avoid rounding errors
+
+## [1.2.2]
+- Internal maintenance: fix lints for Flutter 2.10
+
+## [1.2.1]
+- Fix: Revert Cubic to `PathInterpolator.cubic`
+
+## [1.2.0]
+- Add support for gaussian blurs.
+
+Example to blur some elements dynamically:
+  
+```dart
+Lottie.asset(
+  'assets/AndroidWave.json',
+  delegates: LottieDelegates(values: [
+    ValueDelegate.blurRadius(
+      ['**'], // The path to the element to blur
+      value: 20,
+    ),
+  ]),
+)
+```
+
+- Add support for drop shadows.
+
+Example to add a shadow dynamically:
+```dart
+Lottie.asset(
+  'assets/animation.json',
+  delegates: LottieDelegates(values: [
+    ValueDelegate.dropShadow(
+      ['**'], // The path to the elements with shadow
+      value: const DropShadow(
+        color: Colors.blue,
+        direction: 140,
+        distance: 60,
+        radius: 10,
+      ),
+    ),
+  ]),
+)
+```
+
 ## [1.1.0]
 - Add `errorBuilder` callback to provide an alternative widget in case an error occurs during loading.
 ```dart
