 This release makes the following changes to the API.  You may need to update your implementation to
 accommodate these changes.
 
+- Check value of ManyToManyField in skip_row() (#1271)
+   - This fixes an issue where ManyToMany fields are not checked correctly in `skip_row()`.
+     This means that `skip_row()` now takes `row` as a mandatory arg.
+     If you have overridden `skip_row()` in your own implementation, you will need to add `row`
+     as an arg.
+
+- Use 'create' flag instead of instance.pk (#1362)
+   - ``import_export.resources.save_instance()`` now takes an additional mandatory argument: `is_create`.
+     If you have over-ridden `save_instance()` in your own code, you will need to add this new argument.
+
+- Add support for multiple resources in ModelAdmin. (#1223)
+  - The `*Mixin.resource_class` accepting single resource has been deprecated (will work for few next versions) and
+    the new `*Mixin.resource_classes` accepting subscriptable type (list, tuple, ...) has been added.
+  - Same applies to all of the `get_resource_class`, `get_import_resource_class` and `get_export_resource_class` methods.
+
 - Deprecated `exceptions.py` - this module will be removed in a future release (#1372)
