+- New APIs and options.
+- There's no major breaking changes when updating to `v0.7.0` but there are deprecation notices over Media Store and Environment API.
+
+### New
+
+- `openDocument` API with single and multiple files support @honjow.
+- `openDocumentTree` it now also supports `persistablePermission` option which flags an one-time operation to avoid unused permission issues.
+
+### Deprecation notices
+
+- All non SAF APIs are deprecated (Media Store and Environment APIs), if you are using them, let us know by [opening an issue](https://github.com/alexrintt/shared-storage/issues/new) with your use-case so we can implement a new compatible API using a cross-platform approach.

+### Example project

+- Added a new button that implements `openDocument` API.

 - `getExternalStoragePublicDirectory` was marked as deprecated and should be replaced with an equivalent API depending on your use-case, see [how to migrate `getExternalStoragePublicDirectory`](https://stackoverflow.com/questions/56468539/getexternalstoragepublicdirectory-deprecated-in-android-q). This deprecation is originated from official Android documentation and not by the plugin itself.
