+## Migration operations enhancements
+* `RunSQL`, `RunPython`  
+  Can accept `hints: dict = {}` parameter in order to set migration database alias (`force_migrate_on_databases: List[str]` key) or model (`model: Union[str, Type[ClickHouseModel]]` key)
+  
+
 ## Migration algorithm
 - Get a list of databases from `CLICKHOUSE_DATABASES` setting. Migrate them one by one.  
   - Find all django apps from `INSTALLED_APPS` setting, which have no `readonly=True` attribute and have `migrate=True` attribute. Migrate them one by one.
