 The `AbstractImage` and `AbstractRendition` models use a Wagtail-specific `WagtailImageField` which extends Django's `ImageField` 
 to use [Willow](https://github.com/wagtail/Willow/) for image file handling. This will generate a new migration if you 
 are using a [custom image model](custom_image_model)
+
+### Comments within `InlinePanel` not supported
+
+When the commenting system was introduced, support for `InlinePanel` fields was incorrectly added. This has lead to issues
+where comments can be lost on save or in most cases will be added to the incorrect item within the `InlinePanel`. The ability
+to add comments here has now been removed and as such any existing comments that were added will no longer show.
+
+See https://github.com/wagtail/wagtail/issues/9685 for tracking of adding this back officially in the future.
