 # Changelog
 
+## Unreleased
+
+### Features
+
+- Accept `Map<String, dynamic>` in `Hint` class ([#1807](https://github.com/getsentry/sentry-dart/pull/1807))
+  - Please check if everything works as expected when using `Hint`
+    - Factory constructor `Hint.withMap(Map<String, dynamic> map)` now takes `Map<String, dynamic>` instead of `Map<String, Object>`
+    - Method `hint.addAll(Map<String, dynamic> keysAndValues)` now takes `Map<String, dynamic>` instead of `Map<String, Object>`
+    - Method `set(String key, dynamic value)` now takes value of `dynamic` instead of `Object`
+    - Method `hint.get(String key)` now returns `dynamic` instead of `Object?`
+
