 ### Bug fixes
@@ -156,3 +157,9 @@ When overriding the `get_form_class` method of a ModelAdmin `CreateView` or `Edi
 `StreamField` now requires a `use_json_field` keyword argument that can be set to `True`/`False`. If set to `True`, the field will use `JSONField` as its internal type instead of `TextField`, which will change the data type used on the database and allow you to use `JSONField` lookups and transforms on the `StreamField`. If set to `False`, the field will keep its previous behaviour and no database changes will be made. If set to `None` (the default), the field will keep its previous behaviour and a warning (`RemovedInWagtail50Warning`) will appear.
 
 After setting the keyword argument, make sure to generate and run the migrations for the models.

+### Removal of legacy `clean_name` on `AbstractFormField`
+
+-   If you have a project migrating from pre 2.10 to this release and you are using the Wagtail form builder and you have existing form submissions you must first upgrade to at least 2.11. Then run migrations and run the application with your data to ensure that any existing form fields are correctly migrated.
+-   In Wagtail 2.10 a `clean_name` field was added to form field models that extend `AbstractFormField` and this initially supported legacy migration of the [Unidecode](https://pypi.org/project/Unidecode/) label conversion.
+-   Any new fields created since then will have used the [AnyAscii](https://pypi.org/project/anyascii/) conversion and Unidecode has been removed from the included packages.

remove unidecode and legacy form field clean name
In Wagtail 2.10 the usage of unidecode was replaced with anyascii to ensure that the licenses used in Wagtail were compatible. 

However, we still have not removed the legacy approach and the package. 

After multiple subsequent releases, I think it is time to do this.
